Single and two-dose typhoid conjugate vaccine safety and immunogenicity in HIV-exposed uninfected and HIV-unexposed uninfected Malawian children. Hum Vaccin Immunother 2024; 20:2384760. [PMID: 39263923 PMCID: PMC11404620 DOI: 10.1080/21645515.2024.2384760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 07/03/2024] [Accepted: 07/23/2024] [Indexed: 09/13/2024] Open
Abstract
Vaccine safety and immunogenicity data in human immunodeficiency virus (HIV)-exposed uninfected (HEU) children are important for decision-making in HIV and typhoid co-endemic countries. In an open-label study, we recruited Malawian HEU and HIV unexposed uninfected (HUU) infants aged 9 - 11 months. HEU participants were randomized to receive Vi-tetanus toxoid conjugate vaccine (Vi-TT) at 9 months, Vi-TT at 15 months, or Vi-TT at 9 and 15 months. HUU participants received Vi-TT at 9 and 15 months. Safety outcomes included solicited and unsolicited adverse events (AE) and serious AEs (SAEs) within 7 days, 28 days, and 6 months of vaccination, respectively. Serum was collected before and at day 28 after each vaccination to measure anti-Vi IgG antibodies by enzyme-linked immunosorbent assay (ELISA). Cohort 1 (66 participants) enrollment began 02 December 2019, and follow-up was terminated before completion due to the COVID-19 pandemic. Cohort 2 (100 participants) enrollment began 25 March 2020. Solicited AEs were mostly mild, with no significant differences between HEU and HUU participants or one- and two-dose groups. All six SAEs were unrelated to vaccination. Anti-Vi geometric mean titers (GMT) increased significantly from 4.1 to 4.6 ELISA units (EU)/mL at baseline to 2572.0 - 4117.6 EU/mL on day 28 post-vaccination, and similarly between HEU and HUU participants for both one- and two-dose schedules. All participants seroconverted (>4-fold increase in GMT) by the final study visit. Our findings of comparable safety and immunogenicity of Vi-TT in HUU and HEU children support country introductions with single-dose Vi-TT in HIV-endemic countries.

SARS-CoV-2-specific T-cell responses are induced in people living with human immunodeficiency virus after booster vaccination. Chin Med J (Engl) 2024:00029330-990000000-01148. [PMID: 39028115 DOI: 10.1097/cm9.0000000000003176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND T-cell-mediated immunity is crucial for the effective clearance of viral infection, but the T-cell-mediated immune responses that are induced by booster doses of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in people living with human immunodeficiency virus (PLWH) remain unclear. METHODS Forty-five PLWH who had received antiretroviral therapy (ART) for more than two years and 29 healthy controls (HCs) at Beijing Youan Hospital were enrolled to assess the dynamic changes in T-cell responses between the day before the third vaccine dose (week 0) and 4 or 12 weeks (week 4 or week 12) after receiving the third dose of inactivated SARS-CoV-2 vaccine. Flow cytometry, enzyme-linked immunospot (ELISpot), and multiplex cytokines profiling were used to assess T-cell responses at the three timepoints in this study. RESULTS The results of the ELISpot and activation-induced marker (AIM) assays showed that SARS-CoV-2-specific T-cell responses were increased in both PLWH and HCs after the third dose of the inactivated SARS-CoV-2 vaccine, and a similar magnitude of immune response was induced against the Omicron (B.1.1.529) variant compared to the wild-type strain. In detail, spike-specific T-cell responses (measured by the ELISpot assay for interferon γ [IFN-γ] release) in both PLWH and HCs significantly increased in week 4, and the spike-specific T-cell responses in HCs were significantly stronger than those in PLWH 4 weeks after the third vaccination. In the AIM assay, spike-specific CD4+ T-cell responses peaked in both PLWH and HCs in week 12. Additionally, significantly higher spike-specific CD8+ T-cell responses were induced in PLWH than in HCs in week 12. In PLWH, the release of the cytokines interleukin-2 (IL-2), tumour necrosis factor-alpha (TNF-α), and IL-22 by peripheral blood mononuclear cells (PBMCs) that were stimulated with spike peptides increased in week 12. In addition, the levels of IL-4 and IL-5 were higher in PLWH than in HCs in week 12. Interestingly, the magnitude of SARS-CoV-2-specific T-cell responses in PLWH was negatively associated with the extent of CD8+ T-cell activation and exhaustion. In addition, positive correlations were observed between the magnitude of spike-specific T-cell responses (determined by measuring IFN-γ release by ELISpot) and the amounts of IL-4, IL-5, IL-2 and IL-17F. CONCLUSIONS Our findings suggested that SARS-CoV-2-specific T-cell responses could be enhanced by the booster dose of inactivated COVID-19 vaccines and further illustrate the importance of additional vaccination for PLWH.

Abstract
Vaccine-preventable diseases (VPDs) pose a serious public health concern for people living with HIV (PLH). PLH experience a delayed and weakened response to many vaccines available, compared to the general population. Lower seroconversion rates, along with a decreased efficacy and durability of vaccines, increases the susceptibility of PLH to VPDs. Vaccination guidelines specifically targeting this population have been modified to overcome these challenges. However, vaccine uptake remains suboptimal due to multiple barriers, highlighting the need for further studies and the additional implementation of public health measures specifically tailored to PLH.

Abstract
This narrative review describes genomic characteristic, serotyping, immunogenicity, and vaccine development of Streptococcus pneumoniae capsular polysaccharide (CPS). CPS is a primary virulence factor of S. pneumoniae. The genomic characteristics of S. pneumoniae CPS, including the role of biosynthetic gene and genetic variation within cps (capsule polysaccharide) locus which may lead to serotype replacement are still being investigated. One hundred unique serotypes of S. pneumoniae have been identified through various methods of serotyping using phenotypic and genotypic approach. The advantages and limitations of each method are various, emphasizing the need for accurate and comprehensive serotyping for effective disease surveillance and vaccine targeting. In addition, we elaborate the critical role of CPS in vaccine development by providing an overview of immunogenicity, ongoing research of pneumococcal vaccines, and the impact on disease burden.

Abstract
Background The effect of booster vaccinations with the coronavirus virus disease (COVID-19) vaccine on people living with HIV (PLWH) remains unknown. In this study, we aimed to investigate the immunogenicity and effectiveness of booster doses of the COVID-19 vaccine in PLWH. Methods Literature research was done through the PubMed, Embase, Cochrane Review, and Web of Science databases up to 4 July 2023. Pooled estimates were calculated and compared using the DerSimonian and Laird method for a random effects model. Randomized control trials and observational studies were both considered for inclusion. Results We included 35 eligible studies covering 30,154 PLWH. The pooled immune response rate (IRR) of PLWH after the COVID-19 booster vaccination was 97.25% (95% confidence interval [CI], 93.81-99.49), and similar to healthy control (HC) (risk ratio [RR] = 0.98, 95% CI, 0.96-1.00). The pooled IRR for PLWH with CD4+ T-cell counts ≤ 200 was 86.27 (95% CI, 65.35-99.07). For Omicron variants, the pooled IRR for PLWH after booster dose was 74.07% (95% CI, 58.83-89.30), and the risk of IRR was reduced by 10% in PLWH compared with HC (RR = 0.90, 95% CI, 0.80-1.00). The T-cell immune response of PLWH was found to be comparable to HC (p ≥ 0.05). Subgroup analyses revealed that mRNA vaccines produced a relatively high IRR in PLWH compared to other vaccines. In addition, the results showed that booster vaccination appeared to further reduce the risk of COVID-19-related infections, hospitalizations, and deaths compared with the primary vaccination. Conclusion It was shown that booster vaccination with the COVID-19 vaccine provided a high IRR in PLWH and still produced a desirable moderate IRR in PLWH with a CD4+ T-cell count of ≤ 200. Importantly, the humoral and T-cell responses to booster vaccination in PLWH were comparable to HC, and similar results were observed with the SARS-CoV-2 Omicron variant. Our review strongly emphasizes the effect of mRNA vaccine booster vaccination in PLWH on eliciting desirable protective IRR. Furthermore, booster vaccination appears to further reduce the risk of COVID-19 infection, hospitalization, and death in PLWH compared to primary vaccination. However, more evidence is needed to confirm its effectiveness.

Abstract
OBJECTIVES People with HIV (PWH) experience a greater risk of morbidity and mortality following COVID-19 infection, and poorer immunological responses to several vaccines. We explored existing evidence regarding the immunogenicity, effectiveness, and safety of SARS-CoV-2 vaccines in PWH compared with controls. METHODS We conducted a systematic search of electronic databases from January 2020 until June 2022, in addition to conference databases, to identify studies comparing clinical, immunogenicity, and safety in PWH and controls. We compared results between those with low (<350 cells/μl) and high (>350 cells/μl) CD4 + T-cell counts where possible. We performed a meta-analysis of seroconversion and neutralization responses to calculate a pooled risk ratio as the measure of effect. RESULTS We identified 30 studies, including four reporting clinical effectiveness, 27 immunogenicity, and 12 reporting safety outcomes. PWH were 3% [risk ratio 0.97, 95% confidence interval (95% CI) 0.95-0.99] less likely to seroconvert and 5% less likely to demonstrate neutralization responses (risk ratio 0.95, 95% CI 0.91-0.99) following a primary vaccine schedule. Having a CD4 + T-cell count less than 350 cells/μl (risk ratio 0.91, 95% CI 0.83-0.99) compared with a CD4 + T-cell count more than 350 cells/μl, and receipt of a non-mRNA vaccine in PWH compared with controls (risk ratio 0.86, 95% CI 0.77-0.96) were associated with reduced seroconversion. Two studies reported worse clinical outcomes in PWH. CONCLUSION Although vaccines appear well tolerated in PWH, this group experience poorer immunological responses following vaccination than controls, particularly with non-mRNA vaccines and low CD4 + T-cell counts. PWH should be prioritized for mRNA COVID-19 vaccines, especially PWH with more advanced immunodeficiency.

Abstract
OBJECTIVES To evaluate the safety and immunogenicity of V114 [15-valent pneumococcal conjugate vaccine (PCV) containing serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9 V, 14, 18C, 19A, 19F, 22F, 23F, 33F], followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) 8 weeks later, in children with HIV. DESIGN This phase 3 study (NCT03921424) randomized participants 6-17 years of age with HIV (CD4 + T-cell count ≥200 cells/μl, plasma HIV RNA <50 000 copies/ml) to receive V114 or 13-valent PCV (PCV13) in a double-blind manner on Day 1, followed by PPSV23 at Week 8. METHODS Adverse events (AEs), pneumococcal serotype-specific immunoglobulin G (IgG), and opsonophagocytic activity (OPA) were evaluated 30 days after each vaccination. RESULTS The proportion of participants experiencing at least one AE post-PCV was 78.8% in the V114 group ( n = 203) and 69.6% in the PCV13 group ( n = 204); respective proportions post-PPSV23 were 75.4% ( n = 203) and 77.2% ( n = 202). There were no vaccine-related serious AEs. IgG geometric mean concentrations (GMCs) and OPA geometric mean titers (GMTs) were generally comparable between V114 and PCV13 for shared serotypes at Day 30, and were higher for V114 compared with PCV13 for the additional V114 serotypes 22F and 33F. Approximately 30 days after PPSV23, IgG GMCs and OPA GMTs were generally comparable between the V114 and PCV13 groups for all 15 serotypes in V114. CONCLUSIONS In children with HIV, a sequential administration of V114 followed 8 weeks later with PPSV23 is well tolerated and induces immune responses for all 15 pneumococcal serotypes included in V114.

Abstract
Background Currently, data on long-term immune responses to a homogenous booster dose of the inactivated COVID-19 vaccine are still limited among people living with HIV (PLWH). Methods A prospective cohort study with a 13-month follow-up was conducted in China between March 2021 and August 2022 to evaluate the dynamics of SARS-CoV-2 specific humoral and cellular immunity against three doses of the inactivated COVID-19 vaccine from before the first dose until 6 months after the booster dose vaccination among PLWH in comparison to healthy controls (HC). Results 43 PLWH on antiretroviral therapy (ART) and 23 HC were enrolled. Compared with HC, the neutralizing antibodies (nAbs) levels among PLWH were significantly lower on days 14, 30, 60, 90, and 120 after the booster dose vaccination. Among PLWH, the nAbs titers on days 14, 30, and 60 after the booster dose were significantly higher than the peak of the second dose. However, on day 180 after the booster dose, the nAbs titers were similar to the peak of the second dose vaccination. Compared with HC, the frequencies of IFN-γ-secreting and TNF-α-secreting CD4+ and CD8+ T cells among PLWH were lower on days 14 and 180 after the booster dose vaccination. Among PLWH, increased T cell immunity was induced by the booster dose of the vaccine and kept stable on day 180 after the booster dose vaccination. Conclusion Although a homogenous booster dose following two doses of the inactivated COVID-19 vaccine among PLWH could elicit higher nAb titers, reduce antibody decay, and maintain T cell responses even 6 months after vaccination, the overall immunogenicity of the booster dose was found to be lower among PLWH than among healthy controls. Further strategies are needed to improve immunogenicity to the inactivated COVID-19 vaccine among PLWH.

Abstract
OBJECTIVE The article describes a strategy to facilitate access to pneumococcal conjugate vaccine 13 (PCV-13) for people living with HIV/AIDS (PLHIV) during the COVID-19 pandemic. METHOD report on the experience regarding the organization of a care service for PLHIV in the city of São Paulo to facilitate access to PCV-13 in the framework of the 2020 influenza vaccination campaign during the COVID-19 pandemic. RESULTS through the integration between a PLHIV care service and an Immunization Center (CRIE in Portuguese), it was possible to offer PCV-13 to PLHIV at the point of care, reducing physical barriers to access to immunization. Thus, of the 1,906 PLHIV who passed through the service during the period March 23-July 31, 2020, 84.4% (1,609) received the influenza vaccine, PCV-13 or both. Of the 1609 vaccinated, 50.6% (814) were eligible and received PCV-13. CONCLUSION offering the vaccine at the point of care and orienting PLHIV on the importance of vaccination as a disease prevention strategy, identifying those eligible to receive it, was an important action carried out by the institution together with the nursing team, as a strategy to facilitate access to vaccination.

Abstract
Asplenia (the congenital or acquired absence of the spleen) and hyposplenism (defective spleen function) are common causes of morbidity and mortality. The spleen is a secondary lymphoid organ that is responsible for the regulation of immune responses and blood filtration. Hence, asplenia or hyposplenism increases susceptibility to severe and invasive infections, especially those sustained by encapsulated bacteria (namely, Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b). Asplenia is predominantly due to splenectomy for either traumatic events or oncohaematological conditions. Hyposplenism can be caused by several conditions, including haematological, infectious, autoimmune and gastrointestinal disorders. Anatomical disruption of the spleen and depletion of immune cells, especially IgM memory B cells, seem to be predominantly responsible for the clinical manifestations. Early recognition of hyposplenism and proper management of asplenia are warranted to prevent overwhelming post-splenectomy infections through vaccination and antibiotic prophylaxis. Although recommendations are available, the implementation of vaccination strategies, including more effective and immunogenic vaccines, is needed. Additionally, screening programmes for early detection of hyposplenism in high-risk patients and improvement of patient education are warranted.

Abstract
Vaccine preventable diseases (VPDs) are a prevailing concern among the adult population, despite availability of vaccines. Unlike pediatric vaccination programs, adult vaccination programs lack the required reach, initiative, and awareness. Clinical studies and real-world data have proven that vaccines effectively reduce the disease burden of VPDs and increase life expectancy. In Tunisia and Morocco, the national immunization program (NIP) focuses more on pediatric vaccination and have limited vaccination programs for adults. However, some vaccination campaigns targeting adults are organized. For example, influenza vaccination campaigns prioritizing at risk adults which includes healthcare professionals, elderly, and patients with comorbidities. Women of childbearing age who have never been vaccinated or whose information is uncertain are recommended to receive tetanus vaccination. Tunisia NIP recommends rubella vaccine mainly for women of childbearing age, while in Morocco, national vaccination campaigns were organized for girls and women (up to 24 years of age) to eliminate rubella. Further, travelers from both countries are recommended to follow all requirements and recommendations in the travel destination. The objective of this manuscript is to provide an overview of the global disease burden of common VPDs including (but not limited to) meningococcal diseases, pneumococcal diseases, hepatitis, and influenza. The review also provides an overview of clinical data and guidelines/recommendations on adult vaccination practices, with special focus on Tunisia and Morocco. Some European and North American countries have concrete recommendations and strategies for adult vaccination to keep the VPDs in check. In Morocco and Tunisia, although, there are sporadic adult vaccination initiatives, the efforts still need upscaling and endorsements to boost vaccination awareness and uptake. There is a need to strengthen strategies in both countries to understand the disease burden and spread awareness. Additional studies are needed to generate economic evidence to support cost-effectiveness of vaccines. Integration of private and public healthcare systems may further improve vaccination uptake in adults.

Abstract
The optimal schedule of pneumococcal vaccination after allogeneic hematopoietic stem cell transplantation (allo‐HSCT) remains controversial. The objective of this study was to investigate the immunogenicity of a 5‐dose pneumococcal vaccination schedule in adult allo‐HSCT recipients with and without immunosuppressive therapy. In this prospective cohort study, allo‐HSCT recipients received four doses of the 13‐valent pneumococcal conjugate vaccine (PCV13) and one dose of the 23‐valent pneumococcal polysaccharide vaccine (PPSV23) starting 4–6 months after allo‐HSCT. PCV13 was administered at T0, T1, T2, and T8 (T = months from enrollment) and PPSV23 at T10. Serum was collected at T0, T4, T8, T10, and T12, and IgG levels were measured for all 24 vaccine serotypes by immunoassay. The primary outcome was overall seroprotection at T12 defined as an IgG concentration ≥1.3 μg/ml for 17/24 vaccine serotypes in allo‐HCST recipients with and without immunosuppressive therapy at baseline. Secondary outcomes were serotype‐specific seroprotection and dynamics of IgG levels. We included 89 allo‐HSCT recipients in the final analysis. Overall seroprotection was 47% (15/32) for patients without immunosuppressive therapy at baseline versus 24% (11/46) for patients with immunosuppressive therapy (p = .03). Seroprotection was higher for PCV13 serotypes (78% and 54% respectively; p = .03) and lower for PPSV23‐unique serotypes (28% and 13% respectively; p = .1). IgG concentrations increased significantly over time for all 24 serotypes. Concluding, although immunogenicity of PCV13 serotypes was reasonable, the poor response to PPSV23 serotypes resulted in an insufficient overall response to pneumococcal vaccination for allo‐HSCT recipients. Research into vaccination strategies with higher‐valent T‐cell‐dependent pneumococcal vaccines is needed.

Abstract
OBJECTIVES To evaluate safety and immunogenicity of V114 [15-valent pneumococcal conjugate vaccine (PCV) containing serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F, and 33F], followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) 8 weeks later, in adults living with HIV. DESIGN In this phase 3 study (V114-018; NCT03480802), pneumococcal vaccine-naive adults with HIV (CD4+ cell count ≥50 cells/μl, plasma HIV RNA <50 000 copies/ml, receiving antiretroviral therapy) were randomized 1 : 1 to receive one dose of V114 or licensed 13-valent PCV (PCV13) on day 1; participants received PPSV23 at week 8. METHODS Adverse events and serotype-specific opsonophagocytic activity (OPA) and immunoglobulin G (IgG) antibodies were evaluated after each vaccination. RESULTS Of 302 participants enrolled, 292 (96.7%) completed the study. Proportions of participants experiencing at least one adverse event were 73.0 and 62.7% in the V114 and PCV13 groups following PCV and 60.7 and 71.6% following PPSV23. Most solicited adverse events were of mild or moderate severity and short duration. OPA geometric mean titers (GMTs) and IgG geometric mean concentrations (GMCs) were generally comparable between groups for shared serotypes at day 30 and maintained at week 12. OPA and IgG responses for additional serotypes in V114 (22F, 33F) were higher following V114 than PCV13 at day 30 but comparable at week 12, 30 days post-PPSV23. CONCLUSION In pneumococcal vaccine-naive adults living with HIV, V114 was well tolerated and induced immune responses for all 15 pneumococcal serotypes. V114 can be followed by PPSV23 8 weeks later to broaden serotype coverage.

Abstract
Background Patients living with HIV (PLHIV) are prone to invasive pneumococcal disease. The 13-valent conjugated pneumococcal vaccine (PCV13) is currently recommended for all PLHIV, followed in most guidelines by a 23-valent polysaccharide pneumococcal vaccine. Data are scarce concerning the immunological efficacy of PCV13 among PLHIV. Objective To assess the immunological response at one month, and the immunological protection at 1-, 6-, and 12 months in PLHIV with a CD4 cell count above 200 cells/µl after a single dose of PCV13, as measured by both ELISA and opsonophagocytic assay (OPA). Methods PLHIV with CD4 cell count >200 cells/µl were included. Specific IgG serum concentrations for eight serotypes by ELISA and seven serotypes by OPA were measured at baseline, 1-, 6-, and 12 months after the PCV13 vaccination. Global response was defined as a two-fold increase from baseline of specific IgG antibody levels (μg/ml) assayed by ELISA or as a four-fold increase in OPA titer from baseline, for at least five serotypes targeted by PCV13. Global protection was defined as an IgG-concentration ≥1 µg/ml by ELISA or as an opsonization titer ≥LLOQ by OPA for at least five tested serotypes targeted by PCV13. Factors associated with global response and global protection were assessed using logistic regression. Results Of the 38 PLHIV included, 57.9% and 63.2% were global responders, 92.1% and 78.9% were globally protected at one month, and 64.7% and 55.9% were still protected at 12 months, by ELISA and OPA respectively. A CD4/CD8 ratio of >0.8 was significantly associated with a better global response by OPA (OR=6.11, p=0.02), and a CD4 nadir <200 was significantly associated with a poorer global response by ELISA (OR=0.22, p=0.04). A CD4 cell count nadir <200 and age over 50 years were associated with poorer global protection by OPA at M1 (OR=0.18, p=0.04) and M12 (OR= 0.15, p=0.02), respectively. Plasma HIV RNA viral load <40 copies/ml was significantly associated with a better global protection at M1 by ELISA and OPA (OR=21.33, p=0.025 and OR=8.40, p=0.04) Conclusion Vaccination with PCV13 in these patients induced immunological response and protection at one month. At one year, more than half of patients were still immunologically protected.

Abstract
Pneumococcal disease is one of the most common and severe vaccine-preventable diseases (VPDs). Despite the advances in antimicrobial treatment, pneumococcal disease still remains a global burden and exhibits a high mortality rate among people of all ages worldwide. The immunization program of the pneumococcal conjugate vaccine (PCV) in children has decreased pneumococcal disease incidence in several countries. However, there are several problems regarding the pneumococcal vaccine, such as indications for immunocompetent persons with underlying medical conditions with a risk of pneumococcal disease, the balance of utility and cost, i.e., cost-effectiveness, vaccine coverage rate, serotype replacement, and adverse events. Especially for individuals aged 19-64 at risk of pneumococcal disease, physicians and vaccine providers should make a rational decision whether the patients should be vaccinated or not, since there is insufficient evidence supporting it. We describe this review regarding topics and problems regarding pneumococcal vaccination from the clinician's point of view.

Abstract
BACKGROUND Trials of the Pfizer-BioNTech BNT162b2 mRNA vaccine showed 95% efficacy in preventing symptomatic disease; however, the trials excluded immunocompromised patients (ICPs). We aim at analyzing antibody response in ICPs. METHODS A prospective cohort study was conducted at Sheba Medical Center, Israel, between January and April 2020, in 1274 participants who received the vaccine, including 1002 ICPs and 272 immunocompetent healthcare workers (HCWs). Antibodies were measured two-four weeks after vaccination by SARS-CoV-2 anti-receptor binding domain IgG antibodies (RBD IgG) and pseudo-virus neutralization assays. Multivariable logistic regression analyses were used to identify factors associated with vaccine-induced antibody response. Adverse events (AEs) were monitored. FINDINGS RBD-IgG antibodies were detected in 154/156 (98.7%) of patients with HIV, 75/90 (83.3%) with solid malignancies, 149/187 (79.7%) with myeloma, 83/111 (74.8%) following hematopoietic stem cell transplants, 25/36 (69.4%) following liver transplantation, 26/43 (60.5%) with myelodysplastic syndrome, 96/188 (51.0%) with chronic lymphocytic leukemia/non-Hodgkin's lymphoma, 50/110 (45.5%) following kidney transplantation, 15/80 (18.8%) following heart transplantation, and 269/272 (98.9%) in controls. There was a significant correlation r = 0.74 (95%CI 0.69,0.78) between RBD-binding IgG and neutralizing antibodies in all groups. Multivariate logistic regression analysis showed that age > 65 years (OR 0.41,95%CI 0.30,0.57) and underlying immunosuppression (OR 0.02,95%CI 0.01,0.07) were significantly associated with a non-reactive response of IgG antibodies. HIV patients showed a similar immunological response as healthy adults. The vaccine was safe without any episodes of rejection, graft-versus-host disease (GVHD) or allergy. Immunocompetent HCWs experienced significantly more AEs than ICPs. INTERPRETATION Antibody response to the Pfizer-BioNTech vaccine was highly variable among different ICPs; thus, individual recommendations should be provided for the different immunosuppression states.

Abstract
Infections with the pathogen, Streptococcus pneumoniae, are a common cause of morbidity and mortality worldwide. It particularly affects those at the extremes of age and immunocompromised individuals. Preventing pneumococcal disease is paramount in at risk individuals, and pneumococcal vaccination should be offered. Here, we discuss the role of pneumococcal vaccination in specific groups of immunocompromised hosts.
