Abstract
BACKGROUND An mRNA-based RSV vaccine, mRNA-1345, is under clinical investigation to address RSV disease burden in older adults. METHODS This phase 1, randomized, observer-blind, placebo-controlled, dose-ranging study evaluated safety, reactogenicity, and immunogenicity of mRNA-1345 in adults 65-79 years (NCT04528719). Participants were randomized to receive 1-dose of mRNA-1345 (12.5, 25, 50, 100, or 200-µg) or placebo and matched mRNA-1345 booster or placebo at 12-months. RESULTS Overall, 298 participants received the first injection; 247 received the 12-month booster injection. mRNA-1345 was generally well-tolerated after both injections, with the most frequently reported solicited adverse reactions being injection-site pain, fatigue, headache, arthralgia, and myalgia. Reactogenicity was higher after the booster injection than the first injection but similar severity, time-to-onset, and duration. A single mRNA-1345 injection boosted RSV-A and RSV-B neutralizing antibody titers (nAb) and prefusion-F-binding antibody (preF-bAb) concentrations at 1-month (geometric mean-fold rises: RSV-A, 10.2-16.5; RSV-B, 5.3-12.5; preF-bAb, 7.2-12.1). RSV antibody levels remained above baseline through 12-months, indicating immune persistence. A 12-month booster injection also increased RSV-A and RSV-B nAb titers and preF-bAb concentrations; titers post-booster injection were numerically lower compared to titers after the first-dose, with overlapping 95% CIs. CONCLUSIONS mRNA-1345 was well-tolerated and immunogenic following a single injection and a 12-month booster. TRIAL REGISTRATION ClinicalTrials.gov, NCT04528719.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) presents a global health concern. A lipid nanoparticle-encapsulated mRNA-based RSV vaccine (mRNA-1345) encoding the membrane-anchored RSV prefusion stabilised F glycoprotein (preF) is under clinical investigation. METHODS This phase 1, randomized, observer-blind, placebo-controlled dose escalation study assessed safety and immunogenicity of mRNA-1345 in healthy adults aged 18-49 years (NCT04528719). Participants were randomized to receive one dose of mRNA-1345 (50, 100, or 200 µg) or placebo, or 3 doses of mRNA-1345 (100 µg) or placebo 56 days apart. RESULTS mRNA-1345 was well-tolerated at all dose levels. The most common solicited adverse reactions were pain, headache, fatigue, myalgia, or chills, which were all generally mild to moderate. A single injection of mRNA-1345 boosted RSV neutralizing antibody titers (geometric mean fold rise [GMFR]: RSV-A, 20.0 to 23.5; RSV-B, 11.7 to 16.0) and RSV preF binding antibody concentrations (GMFR: 16.1 to 21.8) at 1 month post injection, with no apparent dose response. Antibody levels remained above baseline through 6 months. Sequential doses of 100 µg were well tolerated but did not further boost antibody levels. CONCLUSIONS A single mRNA-1345 injection demonstrated an acceptable safety profile in younger adults and induced a durable neutralizing antibody response, supporting its continued development.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) is a common cause of lower respiratory tract infections in infants. This phase 1/2, observer-blind, randomized, controlled study assessed the safety and immunogenicity of an investigational chimpanzee-derived adenoviral vector RSV vaccine (ChAd155-RSV, expressing RSV F, N, and M2-1) in infants. METHODS Healthy 6- to 7-month-olds were 1:1:1-randomized to receive 1 low ChAd155-RSV dose (1.5 × 1010 viral particles) followed by placebo (RSV_1D); 2 high ChAd155-RSV doses (5 × 1010 viral particles) (RSV_2D); or active comparator vaccines/placebo (comparator) on days 1 and 31. Follow-up lasted approximately 2 years. RESULTS Two hundred one infants were vaccinated (RSV_1D: 65; RSV_2D: 71; comparator: 65); 159 were RSV-seronaive at baseline. Most solicited and unsolicited adverse events after ChAd155-RSV occurred at similar or lower rates than after active comparators. In infants who developed RSV infection, there was no evidence of vaccine-associated enhanced respiratory disease (VAERD). RSV-A neutralizing titers and RSV F-binding antibody concentrations were higher post-ChAd155-RSV than postcomparator at days 31, 61, and end of RSV season 1 (mean follow-up, 7 months). High-dose ChAd155-RSV induced stronger responses than low-dose, with further increases post-dose 2. CONCLUSIONS ChAd155-RSV administered to 6- to 7-month-olds had a reactogenicity/safety profile like other childhood vaccines, showed no evidence of VAERD, and induced a humoral immune response. Clinical Trials Registration. NCT03636906.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) can cause substantial morbidity and mortality among older adults. An mRNA-based RSV vaccine, mRNA-1345, encoding the stabilized RSV prefusion F glycoprotein, is under clinical investigation. METHODS In this ongoing, randomized, double-blind, placebo-controlled, phase 2-3 trial, we randomly assigned, in a 1:1 ratio, adults 60 years of age or older to receive one dose of mRNA-1345 (50 μg) or placebo. The two primary efficacy end points were the prevention of RSV-associated lower respiratory tract disease with at least two signs or symptoms and with at least three signs or symptoms. A key secondary efficacy end point was the prevention of RSV-associated acute respiratory disease. Safety was also assessed. RESULTS Overall, 35,541 participants were assigned to receive the mRNA-1345 vaccine (17,793 participants) or placebo (17,748). The median follow-up was 112 days (range, 1 to 379). The primary analyses were conducted when at least 50% of the anticipated cases of RSV-associated lower respiratory tract disease had occurred. Vaccine efficacy was 83.7% (95.88% confidence interval [CI], 66.0 to 92.2) against RSV-associated lower respiratory tract disease with at least two signs or symptoms and 82.4% (96.36% CI, 34.8 to 95.3) against the disease with at least three signs or symptoms. Vaccine efficacy was 68.4% (95% CI, 50.9 to 79.7) against RSV-associated acute respiratory disease. Protection was observed against both RSV subtypes (A and B) and was generally consistent across subgroups defined according to age and coexisting conditions. Participants in the mRNA-1345 group had a higher incidence than those in the placebo group of solicited local adverse reactions (58.7% vs. 16.2%) and of systemic adverse reactions (47.7% vs. 32.9%); most reactions were mild to moderate in severity and were transient. Serious adverse events occurred in 2.8% of the participants in each trial group. CONCLUSIONS A single dose of the mRNA-1345 vaccine resulted in no evident safety concerns and led to a lower incidence of RSV-associated lower respiratory tract disease and of RSV-associated acute respiratory disease than placebo among adults 60 years of age or older.

Abstract
BACKGROUND There are limited data describing adverse infant outcomes in infants born to women with a low risk of complications during pregnancy, such as those who may be enrolled in maternal immunization trials. This retrospective study estimated incidence proportions of infant outcomes in different cohorts of liveborn infants in England between 2005 and 2017. METHODS The incidence proportions of 10 infant outcomes were calculated for liveborn infants from pregnancies represented in the Clinical Practice Research Datalink (CPRD) Mother-Baby Link (MBL) and linkage to Hospital Episode Statistics (HES). Three infant cohorts were designed: (1) the all pregnancies infants cohort (N = 185,119), (2) the all pregnancies with a gestational age (GA) ≥ 24 weeks infants cohort (N = 183,869), and (3) the low-risk pregnancies infants cohort (LR infants cohort, N = 121,871), which included pregnancies with a GA ≥ 24 weeks and no diagnosis of predefined high-risk medical conditions until 24 weeks GA. RESULTS The most common adverse infant outcome in the three infant cohorts was macrosomia (e.g., 1,085.9/10,000 live births in the LR infants cohort), followed by minor congenital anomalies (e.g., 800.6/10,000 in the LR infants cohort), very low/low birth weight (e.g., 400.6/10,000 in the LR infants cohort), and major congenital anomalies (e.g., 270.4/10,000 in the LR infants cohort). The incidence proportions for early-onset sepsis, very low/low birth weight, and minor and major congenital anomalies were lower in the LR infants than in the other cohorts (non-overlapping confidence intervals [CIs]). The incidence proportions of neonatal death, infant death, late-onset sepsis, macrosomia, small for GA, and large for GA were similar between cohorts (overlapping CIs). CONCLUSIONS This study generated background rates of adverse infant outcomes from liveborn infants of all and low-risk pregnancies represented in the CPRD Pregnancy Register MBL and linkage to HES. The results indicate lower incidence proportions of several adverse infant outcomes in infants from low-risk pregnancies compared to all pregnancies, illustrating the importance of considering maternal risk factors. These background rates may facilitate the interpretation of safety data from maternal immunization trials and of pharmacovigilance data from maternal vaccines. They may also be of interest for other interventions studied in pregnant women.

Abstract
BACKGROUND Various case definitions of respiratory syncytial virus lower respiratory tract infection (RSV-LRTI) are currently proposed. We assessed the performance of three clinical case definitions against the World Health Organization definition recommended in 2015 (WHO 2015). METHODS In this prospective cohort study conducted in eight countries, 2401 children were followed up during 2 years from birth. Suspected LRTIs were detected via active and passive surveillance, followed by in-person clinical evaluation including single timepoint respiratory rate and oxygen saturation (by pulse oximetry) assessment, and nasopharyngeal sampling for RSV testing by polymerase chain reaction. Agreement between case definitions was evaluated using Cohen's κ statistics. RESULTS Of 1652 suspected LRTIs, 227 met the WHO 2015 criteria for RSV-LRTI; 73 were classified as severe. All alternative definitions were highly concordant with the WHO 2015 definition for RSV-LRTI (κ: 0.95-1.00), but less concordant for severe RSV-LRTI (κ: 0.47-0.82). Tachypnea was present for 196/226 (86.7%) WHO 2015 RSV-LRTIs and 168/243 (69.1%) LRTI/bronchiolitis/pneumonia cases, clinically diagnosed by non-study physicians. Low oxygen saturation levels were observed in only 55/226 (24.3%) WHO 2015 RSV-LRTIs. CONCLUSION Three case definitions for RSV-LRTI showed high concordance with the WHO 2015 definition, while agreement was lower for severe RSV-LRTI. In contrast to increased respiratory rate, low oxygen saturation was not a consistent finding in RSV-LRTIs and severe RSV-LRTIs. This study demonstrates that current definitions are highly concordant for RSV-LRTIs, but a standard definition is still needed for severe RSV-LRTI.

Abstract
Background Respiratory syncytial virus (RSV) is a public health burden; no vaccine is currently available. An mRNA-based RSV vaccine (mRNA-1345) encoding the RSV prefusion stabilized F (preF) glycoprotein is under clinical investigation. Methods A phase 1, randomized, observer-blind, placebo-controlled, dose-ranging study assessed safety and immunogenicity of mRNA-1345 in younger adults (YA; 18-49 years) and older adults (OA; 65-79 years) (NCT04528719). YA and OA were randomized to receive 1 dose of mRNA-1345 (50, 100, or 200 µg) or placebo. Results In all, 74 YA participants (mRNA-1345, n=19-20; placebo, n=15) and 202 OA participants (mRNA-1345, n=47-48; placebo, n=59) received study injections. mRNA-1345 was well-tolerated in both groups, with lower reactogenicity observed in OA vs YA at higher doses. Injection site pain was the most frequent local solicited adverse reaction (SAR, YA: mRNA-1345, 73.7-100%; placebo, 0%; OA: mRNA-1345, 61.7-78.7%; placebo, 12.7% [Fig 1]). Erythema and swelling were less frequent (mRNA-1345: YA, 5.3-15.0%; OA, 0-4.3%; and YA, 5.0-15.0%; OA, 2.1-4.3%; respectively vs placebo 0% for all). Overall, 57.9-100% (YA) and 53.2-78.7% (OA) of mRNA-1345 and 40.0% (YA) and 45.5% (OA) of placebo groups reported ≥ 1 systemic SAR, most commonly headache, fatigue, myalgia, and arthralgia. As expected, neutralizing antibodies (nAbs) were present at baseline (BL; Fig 2); mRNA-1345 significantly boosted antibody titers through month (M) 1 in YA and OA, with comparable immunogenicity observed across age groups. M1 geometric mean fold rise (GMFR) for RSV-A nAbs were 20.0-22.3 (YA) and 12.1-16.6 (OA) and for RSV-B, nAbs were 11.7-14.4 (YA) and 8.7-12.6 (OA). M1 PreF binding antibody (bAb) GMFRs were 16.1-21.7 (YA) and 8.4-12.1 (OA; Fig 3). Peak antibody titers declined through M6, but levels remained ≥ 4.1-fold above BL with minimal dose response. M6 GMFR for RSV-A nAbs were 7.0-9.6 (YA) and 4.1-5.8 (OA) and for RSV-B, nAbs were 5.0-8.9 (YA) and 4.5-5.5 (OA). M6 PreF bAbs GMFR were 5.9-7.0 (YA) and 4.1-4.7 (OA). Antibody decline over time was comparable in YA and OA cohorts.
![]() ![]() ![]() Conclusion mRNA-1345 is well-tolerated in YA and OA. Antibody levels were boosted substantially above BL through M6 in both cohorts. These data support the continued development of mRNA-1345 as an RSV vaccine. Disclosures Grace L.

Abstract
Background The true burden of lower respiratory tract infections (LRTIs) due to respiratory syncytial virus (RSV) remains unclear. This study aimed to provide more robust, multinational data on RSV-LRTI incidence and burden in the first 2 years of life. Methods This prospective, observational cohort study was conducted in Argentina, Bangladesh, Canada, Finland, Honduras, South Africa, Thailand, and United States. Children were followed for 24 months from birth. Suspected LRTIs were detected via active (through regular contacts) and passive surveillance. RSV and other viruses were detected from nasopharyngeal swabs using PCR-based methods. Results Of 2401 children, 206 (8.6%) had 227 episodes of RSV-LRTI. Incidence rates (IRs) of first episode of RSV-LRTI were 7.35 (95% confidence interval [CI], 5.88–9.08), 5.50 (95% CI, 4.21–7.07), and 2.87 (95% CI, 2.18–3.70) cases/100 person-years in children aged 0–5, 6–11, and 12–23 months. IRs for RSV-LRTI, severe RSV-LRTI, and RSV hospitalization tended to be higher among 0–5 month olds and in lower-income settings. RSV was detected for 40% of LRTIs in 0–2 month olds and for approximately 20% of LRTIs in older children. Other viruses were codetected in 29.2% of RSV-positive nasopharyngeal swabs. Conclusions A substantial burden of RSV-LRTI was observed across diverse settings, impacting the youngest infants the most. Clinical Trials Registration. NCT01995175.

Abstract
Background Maternal characteristics like medical history and health-related risk factors can influence the incidence of pregnancy outcomes and pregnancy-related events of interest (EIs). Data on the incidence of these endpoints in low-risk pregnant women are needed for appropriate external safety comparisons in maternal immunization trials. To address this need, this study estimated the incidence proportions of pregnancy outcomes and pregnancy-related EIs in different pregnancy cohorts (including low-risk pregnancies) in England, contained in the Clinical Practice Research Datalink (CPRD) Pregnancy Register linked to Hospital Episode Statistics (HES) between 2005 and 2017. Methods The incidence proportions of 7 pregnancy outcomes and 15 EIs were calculated for: (1) all pregnancies (AP) represented in the CPRD Pregnancy Register linked to HES (AP cohort; N = 298 155), (2) all pregnancies with a gestational age (GA) ≥ 24 weeks (AP24+ cohort; N = 208 328), and (3) low-risk pregnancies (LR cohort; N = 137 932) with a GA ≥ 24 weeks and no diagnosis of predefined high-risk medical conditions until 24 weeks GA. Results Miscarriage was the most common adverse pregnancy outcome in the AP cohort (1 379.5 per 10 000 pregnancies) but could not be assessed in the other cohorts because these only included pregnancies with a GA ≥ 24 weeks, and miscarriages with GA ≥ 24 weeks were reclassified as stillbirths. Preterm delivery (< 37 weeks GA) was the most common adverse pregnancy outcome in the AP24+ and LR cohorts (742.9 and 680.0 per 10 000 pregnancies, respectively). Focusing on the cohorts with a GA ≥ 24 weeks, the most common pregnancy-related EIs in the AP24+ and LR cohorts were fetal/perinatal distress or asphyxia (1 824.3 and 1 833.0 per 10 000 pregnancies), vaginal/intrauterine hemorrhage (799.2 and 729.0 per 10 000 pregnancies), and labor protraction/arrest disorders (752.4 and 774.5 per 10 000 pregnancies). Conclusions This study generated incidence proportions of pregnancy outcomes and pregnancy-related EIs from the CPRD for different pregnancy cohorts, including low-risk pregnancies. The reported incidence proportions of pregnancy outcomes and pregnancy-related EIs are largely consistent with external estimates. These results may facilitate the interpretation of safety data from maternal immunization trials and the safety monitoring of maternal vaccines. They may also be of interest for any intervention studied in populations of pregnant women.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) is the most common cause of acute lower respiratory infection in young children. We previously estimated that in 2015, 33·1 million episodes of RSV-associated acute lower respiratory infection occurred in children aged 0-60 months, resulting in a total of 118 200 deaths worldwide. Since then, several community surveillance studies have been done to obtain a more precise estimation of RSV associated community deaths. We aimed to update RSV-associated acute lower respiratory infection morbidity and mortality at global, regional, and national levels in children aged 0-60 months for 2019, with focus on overall mortality and narrower infant age groups that are targeted by RSV prophylactics in development. METHODS In this systematic analysis, we expanded our global RSV disease burden dataset by obtaining new data from an updated search for papers published between Jan 1, 2017, and Dec 31, 2020, from MEDLINE, Embase, Global Health, CINAHL, Web of Science, LILACS, OpenGrey, CNKI, Wanfang, and ChongqingVIP. We also included unpublished data from RSV GEN collaborators. Eligible studies reported data for children aged 0-60 months with RSV as primary infection with acute lower respiratory infection in community settings, or acute lower respiratory infection necessitating hospital admission; reported data for at least 12 consecutive months, except for in-hospital case fatality ratio (CFR) or for where RSV seasonality is well-defined; and reported incidence rate, hospital admission rate, RSV positive proportion in acute lower respiratory infection hospital admission, or in-hospital CFR. Studies were excluded if case definition was not clearly defined or not consistently applied, RSV infection was not laboratory confirmed or based on serology alone, or if the report included fewer than 50 cases of acute lower respiratory infection. We applied a generalised linear mixed-effects model (GLMM) to estimate RSV-associated acute lower respiratory infection incidence, hospital admission, and in-hospital mortality both globally and regionally (by country development status and by World Bank Income Classification) in 2019. We estimated country-level RSV-associated acute lower respiratory infection incidence through a risk-factor based model. We developed new models (through GLMM) that incorporated the latest RSV community mortality data for estimating overall RSV mortality. This review was registered in PROSPERO (CRD42021252400). FINDINGS In addition to 317 studies included in our previous review, we identified and included 113 new eligible studies and unpublished data from 51 studies, for a total of 481 studies. We estimated that globally in 2019, there were 33·0 million RSV-associated acute lower respiratory infection episodes (uncertainty range [UR] 25·4-44·6 million), 3·6 million RSV-associated acute lower respiratory infection hospital admissions (2·9-4·6 million), 26 300 RSV-associated acute lower respiratory infection in-hospital deaths (15 100-49 100), and 101 400 RSV-attributable overall deaths (84 500-125 200) in children aged 0-60 months. In infants aged 0-6 months, we estimated that there were 6·6 million RSV-associated acute lower respiratory infection episodes (4·6-9·7 million), 1·4 million RSV-associated acute lower respiratory infection hospital admissions (1·0-2·0 million), 13 300 RSV-associated acute lower respiratory infection in-hospital deaths (6800-28 100), and 45 700 RSV-attributable overall deaths (38 400-55 900). 2·0% of deaths in children aged 0-60 months (UR 1·6-2·4) and 3·6% of deaths in children aged 28 days to 6 months (3·0-4·4) were attributable to RSV. More than 95% of RSV-associated acute lower respiratory infection episodes and more than 97% of RSV-attributable deaths across all age bands were in low-income and middle-income countries (LMICs). INTERPRETATION RSV contributes substantially to morbidity and mortality burden globally in children aged 0-60 months, especially during the first 6 months of life and in LMICs. We highlight the striking overall mortality burden of RSV disease worldwide, with one in every 50 deaths in children aged 0-60 months and one in every 28 deaths in children aged 28 days to 6 months attributable to RSV. For every RSV-associated acute lower respiratory infection in-hospital death, we estimate approximately three more deaths attributable to RSV in the community. RSV passive immunisation programmes targeting protection during the first 6 months of life could have a substantial effect on reducing RSV disease burden, although more data are needed to understand the implications of the potential age-shifts in peak RSV burden to older age when these are implemented.

Abstract
Background Lower respiratory tract infections (LRTIs) are a leading cause of pediatric morbidity and mortality worldwide, with ~650,000 deaths recorded in < 5-year-olds in 2016. Cross-sectional studies on hospitalized LRTIs are available, but longitudinal studies on the total burden of viral LRTIs are scarce. This study (NCT01995175) prospectively collected incident RSV and other viral LRTIs in a multinational cohort. Methods From 2013 to 2017, infants in 8 countries were enrolled at birth and followed for LRTIs up to 2 years of age. Infants with suspected LRTIs were clinically examined and swabbed. Nasal swab samples were tested using quantitative real-time PCR for RSV and multiplex PCR panel for 16 other respiratory viruses/subtypes; bacterial culture was not performed. LRTI and severe LRTI episodes were defined per 2015 WHO LRTI case definitions. Viruses detected from nasal swabs collected from participants with WHO-defined LRTI and severe LRTI episodes are reported. Results The 2401 infants followed experienced 1012 LRTI episodes; 259 of these were severe LRTIs. At least 1 virus was detected from 909 (90%) and 235 (91%) LRTI and severe LRTI episodes, respectively. Enteroviruses/Rhinoviruses (EV/RV, 49%) were detected most frequently in samples collected from LRTI episodes, followed by RSV (22%), parainfluenza (PIV, 14%), human metapneumovirus (hMPV, 8%) and seasonal coronavirus (CoV, 6%). RSV was detected in 39% of samples from LRTI episodes in < 3-month-olds and in 18% of 1-year-olds (Table 1). In a similar trend, RSV was detected in 47% of samples from severe LRTI episodes in < 3-month-olds and in 21% of 1-year-olds (Table 2). Co-infection with another virus was common in CoV-positive samples (67%), while most samples positive for RSV (71%), hMPV (70%), EV/RV (67%) and PIV (58%) had no other virus detected. Table 1. Occurrence of laboratory confirmed respiratory viral infections by viral pathogens identified in nasal swab samples from WHO-defined LRTI episodes ![]()
Table 2. Occurrence of laboratory confirmed respiratory viral infections by viral pathogens identified in nasal swab samples from WHO-defined severe LRTI episodes ![]()
Conclusion Respiratory viruses are detected in the majority of LRTIs during the first 2 years of life. RSV likely accounts for much of this overall LRTI burden. Our results suggest that RSV most strongly impacted the very young; it was the most commonly detected virus in severe LRTIs in infants aged < 3 months. RSV was also persistently detected at high levels in samples from LRTIs (22%) and severe LRTIs (28%) in children up to 2 years old.

Abstract
Respiratory syncytial virus-associated acute respiratory infection (RSV-ARI) constitutes a substantial disease burden in older adults aged ≥65 years. We aimed to identify all studies worldwide investigating the disease burden of RSV-ARI in this population. We estimated the community incidence, hospitalization rate, and in-hospital case-fatality ratio (hCFR) of RSV-ARI in older adults, stratified by industrialized and developing regions, using data from a systematic review of studies published between January 1996 and April 2018 and 8 unpublished population-based studies. We applied these rate estimates to population estimates for 2015 to calculate the global and regional burdens in older adults with RSV-ARI in the community and in hospitals for that year. We estimated the number of in-hospital deaths due to RSV-ARI by combining hCFR data with hospital admission estimates from hospital-based studies. In 2015, there were about 1.5 million episodes (95% confidence interval [CI], .3 million-6.9 million) of RSV-ARI in older adults in industrialized countries (data for developing countries were missing), and of these, approximately 14.5% (214 000 episodes; 95% CI, 100 000-459 000) were admitted to hospitals. The global number of hospital admissions for RSV-ARI in older adults was estimated at 336 000 hospitalizations (uncertainty range [UR], 186 000-614 000). We further estimated about 14 000 in-hospital deaths (UR, 5000-50 000) related to RSV-ARI globally. The hospital admission rate and hCFR were higher for those aged ≥65 years than for those aged 50-64 years. The disease burden of RSV-ARI among older adults is substantial, with limited data from developing countries. Appropriate prevention and management strategies are needed to reduce this burden.

Abstract
Background Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infections (LRTI) during infancy worldwide. High cord blood (CB) concentrations of anti-RSV neutralizing antibody (nAb) may attenuate, delay, or prevent infant infection. We report RSV A and B nAb concentrations in CB and serum from a birth cohort at different time points through 2 years of age. Methods Between 2013 and 2017, newborns from 8 countries were studied prospectively from birth to 2 years of age (NCT01995175). CB was collected at birth for the entire cohort. A subcohort of children was randomly assigned to have one blood sample collected again at either 2, 4, 6, 12, 18, or 24 months of age. Sera were analyzed for RSV A and B nAb concentrations by serum neutralization assay. Active surveillance was used to identify LRTIs during the 2-year follow-up as previously reported. Results In total, 2,401 newborns were enrolled and followed up. >99% of infants had detectable CB RSV A and B nAb. Geometric mean antibody titers (GMTs) varied by country, but were overall higher for RSV B than for RSV A (327 vs. 251; Figure 1). The lowest GMTs were seen from CB sera collected from South African newborns (197 RSV A, 255 RSV B); Canadian newborns had the highest RSV A GMT (383), while Hondurans had the highest RSV B GMT (460). 1380 infants provided follow-up serum nAb results as part of the subcohort (Figure 2). Dramatic waning of GMTs was evident, with a ~3-fold drop in GMTs at 2 months of age, and an additional ~2-fold drop between 2 and 4 months of age. At 6 and 12 months of age, 71% and 50% of infants had RSV A nAb and GMTs were at a nadir of 14. At 6, 12, and 18 months of age, RSV B nAb was detected in 98%, 69%, and 63% of infants, respectively. The RSV B nAb nadir GMT of 20 was observed at 12 months of age, while the 6- and 18-month RSV B nAb GMTs were 30 and 31, respectively. A total of 1,017 LRTIs were identified during the 2-year study period; of which, 94 (9%) were caused by RSV A and 132 (13%) by RSV B. Associations between CB nAb levels and RSV infection will be presented. Conclusion Neutralizing Ab to RSV A and B was present at birth in infants from 8 countries, and waned over time. GMTs were at a nadir at 6 to 12 months of age. Funding. GlaxoSmithKline Biologicals SA. ![]()

Abstract
AbstractPneumonia constitutes a substantial disease burden among adults overall and those who are elderly. We aimed to identify all studies investigating the disease burden among older adults (age, ≥65 years) admitted to the hospital with pneumonia. We estimated the hospital admission rate and in-hospital case-fatality ratio (CFR) of pneumonia in older adults, stratified by age and economic status (industrialized vs developing), with data from a systematic review of studies published from 1996 through 2017 and from 8 unpublished population-based studies. We applied these rate estimates to population estimates for 2015 to calculate the global and regional burden in older adults who would have been admitted to the hospital with pneumonia that year. We estimated the number of in-hospital pneumonia deaths by combining in-hospital CFRs with hospital admission estimates from hospital-based studies. We identified 109 eligible studies; 73 used clinical pneumonia as the case definition, and 36 used radiologically confirmed pneumonia as the case definition. We estimated that, in 2015, 6.8 million episodes (uncertainty range [UR], 5.8–8.0 episodes) of clinical pneumonia resulted in hospital admissions of older adults worldwide. The hospital admission rate increased with advancing age and was higher in men. The total disease burden was likely underestimated when using the definition of radiologically confirmed pneumonia. Based on data from 52 hospital studies reporting data on pneumonia mortality, we estimated that about 1.1 million in-hospital deaths (UR, 0.9–1.4 in-hospital deaths) occurred among older adults. The burden of pneumonia requiring hospitalization among older adults is substantial. Appropriate prevention and management strategies should be developed to reduce its impact.

Abstract
We estimated the prevalence of human immunodeficiency virus (HIV) disclosure in children from a prospective observational cohort study conducted at clinical sites in Brazil, Mexico, and Peru. Fewer than half of the children in this study knew their HIV status, which highlights the need for better strategies for disclosure that are age and culturally appropriate.

Abstract
Progress in tuberculosis clinical research is hampered by a lack of reliable biomarkers that predict progression from latent to active tuberculosis, and subsequent cure, relapse, or failure. Regional Prospective Observational Research in Tuberculosis (RePORT) International represents a consortium of regional cohorts (RePORT India, RePORT Brazil, and RePORT Indonesia) that are linked through the implementation of a Common Protocol for data and specimen collection, and are poised to address this critical research need. Each RePORT network is designed to support local, in-country tuberculosis-specific data and specimen biorepositories, and associated research. Taken together, the expected results include greater global clinical research capacity in high-burden settings, and increased local access to quality data and specimens for members of each network and their domestic and international collaborators. Additional networks are expected to be added, helping to spur tuberculosis treatment and prevention research around the world.

Abstract
BACKGROUND The authors assessed acceptance and safety of, and adherence to, perinatal HIV-1 transmission prophylaxis at 2 public hospitals in rural Tamil Nadu, India. METHODS Eligible HIV-1-infected women were offered zidovudine (ZDV) beginning at 28-weeks gestation until delivery. Their infants received ZDV for 6 weeks. A subsequent revision to the protocol added 1 dose of nevirapine (NVP) for mother and infant. RESULTS Sixty of 67 women (90%) met inclusion criteria for the cohort study. Thirty-four of 36 eligible women and all 19 eligible live born infants received prophylaxis on study. Infant, but not maternal, adherence to ZDV varied by antiretroviral prophylaxis group (those receiving combined prophylaxis with ZDV and NVP had lower median adherence) (P = .02). Neutropenia (usually transient) was the most common severe adverse event. Only 1 of 5 women with neutropenia possibly related to ZDV permanently discontinued ZDV. ZDV was not discontinued for any infant. CONCLUSION With the exception of neutropenia, usually transient and always without clinical consequences, long-term ZDV (with or without NVP prophylaxis) is well tolerated.

Abstract
BACKGROUND Maternal human immunodeficiency virus (HIV) coinfection has been associated with increased hepatitis C virus (HCV) mother-to-child transmission (MTCT). We hypothesized that HCV/HIV-coinfected women with well-controlled HIV disease would not have increased HCV MTCT. METHODS The NISDI Perinatal and LILAC cohorts enrolled HIV-infected pregnant women and their infants in Latin America and the Caribbean. This substudy evaluated the HCV infection status of mothers at participating sites and their live born, singleton infants who had a 6-month postnatal visit by December 31, 2008. Mothers who were anti-HCV-positive, or who had CD4 counts (cells/mm(3)) <200 with detectable HCV RNA, were considered HCV-infected. All HCV-infected women were tested for HCV RNA. Infants with HCV RNA were considered HCV-infected. RESULTS Of 1042 enrolled women, 739 (71%) mother-infant pairs met the inclusion criteria. Of the 739 women, 67 (9%) were anti-HCV-positive and 672 anti-HCV-negative [68 (10%) with CD4 counts <200; of these, 3 (4.4%) were HCV RNA-positive]. Therefore, our study population comprised 70 HCV-infected (47 with HCV RNA) and 669 HCV-uninfected women (and their infants). Factors associated with maternal HCV infection included unemployment (odds ratio [OR] = 2.58); tobacco (OR = 1.73) or marijuana (OR = 3.88) use during pregnancy; enrollment HIV viral load ([VL] copies/mL) ≥10 000 (OR = 2.27); HIV clinical disease stage C (OR = 2.12); and abnormal alanine aminotransferase (OR = 4.24) or aspartate aminotransferase (OR = 11.98). Four of 47 infants (8.5%) born to HCV-viremic women were HCV-infected, and all 4 mothers had HIV VL <1000 at hospital discharge after delivery. CONCLUSIONS HCV MTCT among HIV/HCV-coinfected women with well-controlled HIV disease may be lower than reported in other coinfected populations. Studies with longer infant follow-up are needed.

Abstract
OBJECTIVE To describe temporal management and outcome trends among HIV-1-infected pregnant women and their infants enrolled in the NISDI Perinatal and LILAC cohorts. METHODS A prospective cohort of 1548 HIV-1-infected pregnant women and their 1481 singleton live-born infants was analyzed. Participants were enrolled at 24 Latin American and Caribbean sites and followed-up for at least 6 months postpartum. Variables were compared by 2-year enrollment periods from September 27, 2002, to June 30, 2009, using logistic and linear regression modeling. RESULTS Antiretroviral (ARV) use during pregnancy remained high (99.0%). ARVs became increasingly used for treatment (P<0.001). Regimens containing 2 nucleoside reverse transcriptase inhibitors plus a protease inhibitor became more common in later years (P<0.001). The proportion of women with viral loads below 1000 copies/mL at hospital discharge after delivery (HD) increased over time (P=0.0031). Median CD4 lymphocyte counts also rose at HD, from 441 cell/mm(3) to 515 cells/mm(3) (P<0.05). Elective cesarean deliveries increased from 30.5% to 42.0% (P=0.018). Most infants received ARV prophylaxis (99.7%). Few infants were breastfed (0.5%) or became infected with HIV-1 (1.2%). CONCLUSION The results indicate that national HIV-1 treatment and transmission prevention policies are effective among patients with healthcare access in the region.

Abstract
OBJECTIVE To evaluate respiratory morbidity (RM) in HIV-exposed newborns according to mode of delivery. METHODS The NISDI Perinatal/LILAC prospective cohort studies enrolled HIV-infected pregnant women and their newborns in Latin America and the Caribbean. Associations between RM and delivery mode or other characteristics were evaluated. RESULTS Between September 2002 and December 2009, 1630 women were enrolled, and 1443 mother-infant pairs met the inclusion criteria. There were 561 vaginal (VD), 269 cesarean before labor and membrane rupture (SCS) for preventing mother-to-child transmission (SCS-PMTCT), 248 other SCS, and 365 cesarean after labor and/or ruptured membranes (NSCS) deliveries. In total, 108 (7.5%) newborns had RM: 49 had respiratory distress syndrome (RDS), 39 had transient tachypnea (TTN), and 28 had other events (7 newborns had >1 RM event). Delivery mode was associated with RDS (P<0.005) and TTN (P<0.001). The proportion with RDS and TTN was lowest for VD (1.6% and 0.5%, respectively), highest for NSCS (4.9% and 4.7%), and intermediate for SCS-PMTCT (3.0% and 2.6%). Newborns with RDS or TTN were hospitalized longer (median +1day) than those without. A minority required ventilatory support (RDS, 24.5%-28.6%; TTN, 2.6%-15.4%). CONCLUSIONS SCS-PMTCT is relatively safe for newborns of HIV-infected women.

Abstract
A prospective cohort study of the incidence and risk factors for hepatitis C virus (HCV) infection was performed in 2171 pregnant women in three rural Egyptian villages who were HCV antibody (anti-HCV) and RNA (HCV-RNA) negative at baseline. During an average of 2.2 years follow up, 25 incident cases were observed, giving an estimated HCV incidence of 5.2/1000 person-years (PY). The infection rate correlated with community anti-HCV prevalence in pregnant women, while the perinatal incidence rate of 11.2/1000 PY was almost five times that of the non-perinatal rate (2.3/1000 PY). The data suggested iatrogenic perinatal risk factors were associated with infection in one village, while health education reduced infections in another. Among the 25 incident cases, eight were HCV-RNA negative when they were first found to be anti-HCV positive and one-third of the 15 viraemic cases with follow-up data available cleared their HCV-RNA after an average of 1.3 years. None of the 25 incident cases were jaundiced or had symptoms of hepatitis but elevated serum alanine aminotransferase levels confirmed hepatitis in nine. Our data suggest that asymptomatic HCV infections frequently occurred during the perinatal period but often cleared and that educating medical personnel on safe practices possibly reduced HCV transmission.

Abstract
OBJECTIVE To describe the management of a population of human immunodeficiency virus (HIV)-infected pregnant women in Latin America and the Caribbean, and to assess factors associated with maternal viral load of 1,000 copies/mL or more and with infant HIV-1 infection. METHODS Eligibility criteria were enrollment in the prospective cohort study as of March 2006; delivery of a liveborn, singleton infant; and completion of the 6-month postpartum or postnatal visit. RESULTS Of 955 women enrolled in Argentina, the Bahamas, Brazil, and Mexico, 770 mother-infant pairs were eligible. At enrollment, most women were relatively healthy (87% asymptomatic, 59% with viral load less than 1,000 copies/mL, 62% with CD4(+)% of 25% or more). Most (99%) received antiretrovirals during pregnancy (56% prophylaxis, 44% treatment), and 38% delivered by cesarean before labor and before ruptured membranes. Only 18% of women had a viral load of 1,000 copies/mL or more after delivery (associated in adjusted analyses with receipt of antiretrovirals at conception, CD4(+)% [lower], viral load [higher], and country at enrollment, enrollment late in pregnancy, and inversely related to antiretroviral regimen [two nucleoside or nucleotide analogue reverse transcriptase inhibitors plus one nonnucleoside reverse transcriptase inhibitor] during pregnancy). None of the infants breastfed, and all received antiretroviral prophylaxis. Seven infants became infected (0.91%; 95% confidence interval 0.37-1.86). Low birth weight infants and those whose mothers had a low CD4(+)% at hospital discharge after delivery and were not receiving antiretrovirals at enrollment were at higher risk of HIV infection. CONCLUSION Only a minority of women had a viral load of 1,000 copies/mL or more around delivery, and mother-to-child transmission of HIV occurred rarely (1%).

Abstract
Prevalence and risk factors for hepatitis C virus (HCV) infection were studied in 2,587 pregnant women from three rural Egyptian villages in the Nile Delta being admitted to a prospective cohort study of maternal-infant transmission; 408 (15.8%) had antibodies to HCV (anti-HCV) and 279 (10.8%) also had HCV-RNA. Fewer than 1% gave a history of jaundice or liver disease. Risk factors for anti-HCV included increasing age, low socioeconomic status and a history of blood transfusion or injection therapy for schistosomiasis. Sub-analyses after stratification of subjects by village revealed risks associated with specific venues for medical care, having a previous delivery attended by a traditional birth assistant (TBA), receiving medical care in a temporary clinic located in a mosque, overnight admission to a private doctor's clinic, and circumcision by a TBA or a 'health barber'. Our results suggest HCV causes very little detected illness in young adult Egyptian women and some sources of HCV transmission in rural Egypt in the past were associated with the provision of medical care and varied by location. Prevention should be focused on providing appropriate resources and health education should be given to formal and informal health care providers and should be sufficiently broad to adjust for local variations in exposures.

Abstract
BACKGROUND Acute viral hepatitis is less frequent in Egypt than serum antibody levels suggest. Because acute viral hepatitis has a wide clinical spectrum, we tested the hypothesis that many cases are undetected because of mild illness caused by initial, early-childhood exposure to hepatitis viruses. METHODS During active case detection among 20,000 inhabitants of rural villages in Egypt, we screened 1715 symptomatic patients for serum alanine aminotransferase (ALT) levels. Viral hepatitis markers were tested in 47 subjects who had ALT levels that were least twice the normal level. RESULTS Of the 47 individuals tested, 4 children aged 3-5 years had immunoglobulin M (IgM) antibodies to hepatitis A virus (anti-HAV IgM). One also had a possible false-positive result to a test for IgM antibodies to hepatitis E virus. None had serological evidence of acute hepatitis B virus (HBV) infection or hepatitis C virus (HCV) infection. However, 33 of the remaining 43 had active HCV infection, having both antibodies to HCV (anti-HCV) and HCV RNA. Four others anti-HCV without HCV RNA, and 2 others had seroconversion to anti-HCV during follow-up. Two patients who were positive for hepatitis B surface antigen had chronic HBV infection. Only 3 with elevated ALT levels had no evidence of acute or chronic infections with known hepatitis viruses. Immunoglobulin G antibodies to hepatitis E virus was detected in 40 patients. CONCLUSION Active surveillance covering approximately 50,000 person-years detected only 4 cases of acute HAV infection. Almost all persons with mild symptoms and elevated ALT levels had serological evidence of chronic viral hepatitis, most often associated with HCV. Many of these cases were probably "flare-ups" of HCV infection or incidental illness in patients with chronic HCV infection, but some could have been caused by difficult-to-confirm initial HCV infections. Although serological evidence for exposures was highly prevalent, hepatitis viruses seldom caused acute viral hepatitis in these communities.

Abstract
Prevalence and risk factors for hepatitis C virus (HCV) infection were studied in 2,587 pregnant women from three rural Egyptian villages in the Nile Delta being admitted to a prospective cohort study of maternal-infant transmission; 408 (15.8%) had antibodies to HCV (anti-HCV) and 279 (10.8%) also had HCV-RNA. Fewer than 1% gave a history of jaundice or liver disease. Risk factors for anti-HCV included increasing age, low socioeconomic status and a history of blood transfusion or injection therapy for schistosomiasis. Sub-analyses after stratification of subjects by village revealed risks associated with specific venues for medical care, having a previous delivery attended by a traditional birth assistant (TBA), receiving medical care in a temporary clinic located in a mosque, overnight admission to a private doctor's clinic, and circumcision by a TBA or a 'health barber'. Our results suggest HCV causes very little detected illness in young adult Egyptian women and some sources of HCV transmission in rural Egypt in the past were associated with the provision of medical care and varied by location. Prevention should be focused on providing appropriate resources and health education should be given to formal and informal health care providers and should be sufficiently broad to adjust for local variations in exposures.

Abstract
Hepatitis E virus (HEV) is enterically transmitted and causes self-limiting acute viral hepatitis (AVH) primarily in less developed countries. A prospective cohort study to assess incidence of, and risk factors for, seroconversion to HEV (anti-HEV) was conducted in two Egyptian villages with a 67.7% anti-HEV prevalence. Nine hundred and nineteen villagers who were initially anti-HEV-negative were followed for 10.7 months. Thirty-four (3.7%) had strong anti-HEV serologic responses at follow-up giving an estimated anti-HEV incidence of 41.6/1,000 person-years. No significant associations were found between anti-HEV seroincidence and demographic and socioeconomic factors, source of water, household plumbing or sanitation, hand and vegetable washing, ownership of animals, jaundice and many other variables. None of the seroconverting subjects gave a history compatible with AVH during the interval. We hypothesize that both zoonotic and anthroponotic transmission of avirulent (possibly genotype-3) HEV is occurring extensively in these rural villages. An alternative explanation for the lack of morbidity among anti-HEV incident cases could be initial asymptomatic infections occur during early childhood with subsequent antibody titer boosting without illness upon re-exposure to the virus.
