Abstract
Background The administration of COVID-19 vaccines has been critical in controlling the spread of the virus. However, understanding the potential adverse events (AEs) associated with these vaccines is crucial for public health. While most previous studies observed only short-term AEs, this study aimed to investigate the immediate and long-term AEs following the first and second doses of Pfizer, AstraZeneca, and Sinopharm vaccines, providing valuable long-term insights. Methodology A prospective, one-year, follow-up study was conducted by tracking 922 vaccinated individuals to assess short-term and long-term AEs. Demographics, clinical characteristics, vaccine types, and dose effects were taken into consideration. AEs were classified based on severity and duration. Statistical analyses were performed to compare differences among the vaccine groups, with p-values <0.05 considered significant. Bowker's and chi-square tests were performed using JMP Pro 14.3.0. Results Of the 922 participants, 55.53% (n = 512) were vaccinated with Pfizer, and 23.32% (n = 215) and 21.15% (n = 195) were vaccinated with Sinopharm and AstraZeneca, respectively. Overall, 72.34% of participants (n = 667) were suffering from AEs after the first dose, with a lower prevalence of AEs after the second dose (52.71%, n = 486). Pfizer exhibited the highest percentage and severity of AEs, followed by AstraZeneca and Sinopharm. Most AEs reported in this study were mild and resolved within 72 hours, with females experiencing more frequent AEs. The common short-term AEs observed were fever, injection-site pain, myalgia, fatigue, and headache. Notably, there were no chronic AEs, and only one case of myocarditis was associated with AstraZeneca. Conclusions Despite the variation in the prevalence of AEs among the three vaccines, the vaccination process proved to be safe with no serious short-term AEs. However, the long-term AEs associated with AstraZeneca and the decrease in the prevalence of AEs after the second dose of the COVID-19 vaccines warrant further investigations and priority for future research.

Abstract
Coronavirus disease (COVID-19) is among the most contagious viral illnesses, affecting millions worldwide. Although precautions such as social distancing, hand sanitizing, and the use of masks decreased the transmission of the virus, the situation went uncontrolled until vaccination came to light. Vaccination was vital in limiting the incidence, prevalence, and severity caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Based on the mechanism, several types of vaccines, such as Pfizer-BioNTech, Moderna, AstraZeneca, Johnson & Johnson, and Covaxin, were approved by the US Food and Drug Administration (FDA). A booster dose was implemented as the vaccine's effectiveness decreased with time. Several side effects, such as fever, soreness around the injection site, fatigue, chills, muscle weakness, and headache, have been reported after vaccination with Pfizer-BioNTech, but thyroid dysfunction is relatively rare. Several case reports and even case series describing links between COVID-19 vaccination and various types of thyroid dysfunction have appeared in the literature. However, the exact reasons have yet to be explained. This report presents the case of a healthy 50-year-old woman diagnosed with overt hypothyroidism three weeks after the administration of the Pfizer-BioNTech vaccine.

Abstract
Introduction Following the World Health Organization (WHO) declaration of coronavirus disease 2019 (COVID-19) as a pandemic, Saudi Arabia took unpreceded precautions to prevent and control the spread of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) infection. It is one of the first countries in the world to grant the authorization to use the Pfizer-BioNTech vaccine. This study aimed to assess the effect of one dose of COVID-19 vaccines (Pfizer-BioNTech, Manhattan, New York City, and Oxford-AstraZeneca, Cambridge, United Kingdom) among the Saudi population regarding symptom severity, hospital admission rate, and death. Methods An observational retrospective cohort study was conducted using data from COVID-19 surveillance records at King Abdulaziz Medical City (KAMC), Saudi Arabia, from January to May 2021. All confirmed COVID-19 patients who had positive tests by reverse transcription polymerase chain reaction (RT-PCR) assay of a nasopharyngeal swab were included in the study. Patients diagnosed outside KAMC and cases below 18 years old were excluded from the study. The research was approved by King Abdullah International Medical Research Center (NRJ21J/303/12). Multivariable logistic regression was conducted to estimate the odds of hospitalization among vaccinated and unvaccinated patients. Results A total of 1058 cases were included in the analysis. Two hundred sixty-five (265; 25%) patients were vaccinated with one dose of either Pfizer-BioNTech or Oxford Astra-Zeneca, and 793 (75%) were unvaccinated. The median age was 34 (IQR 25-51), primarily Saudi (94.6%) and male (59.5%). The odds of being vaccinated (CI: 1.284-2.882, P 0.002) were 1.924 times greater for males than females. Young patients below 40 had 1.997 times higher odds (CI: 1.238-3.222, P 0.004) of being vaccinated than patients above 60. The hospital admission rate was low among both groups (12.9%); however, it was significantly lower among the vaccinated group (2.3%) as compared to the unvaccinated (16.5%). The results showed significant differences in symptom severity among the groups. For vaccinated, only one patient (0.4%) died, one patient was admitted to the ICU, and one patient (0.4%) was admitted to the hospital isolation ward. On the contrary, among the unvaccinated group, 19 patients (2.4%) died, 17 patients (2.1%) were admitted to the ICU, and 114 patients (14.4%) were admitted to the hospital isolation ward. Conclusion This study demonstrates that one dose of COVID-19 vaccines, either Pfizer-BioNTech or Oxford-AstraZeneca, reduced the probability of death by 2% and hospital admission by 15% before the spread of the Delta variant (B.1.617). For generalizable results, nationwide studies using national surveillance data are recommended to assess multiple doses efficacy on different variants of the SARS-CoV-2 infection.

Abstract
INTRODUCTION There are limited data on the safety profile of the severe acute respiratory syndrome coronavirus-2 vaccine among patients taking immunosuppressive medications. Our aim was to evaluate the adverse events related to the vaccines in a nationwide cohort of patients with inflammatory bowel disease on diverse immunosuppressive medications. METHODS This was a retrospective cohort study using data from the Veterans Health Administration. The primary outcome was any adverse event of special interest (cerebrovascular accident, venous thromboembolism, acute myocardial infarction, Bell palsy) within 90 days of vaccination. RESULTS A total of 17,201 patients were included, and 12,351 patients (71.8%) received at least 1 vaccine dose. The most common adverse events were acute myocardial infarction and venous thromboembolism. In inverse probability treatment weighting-adjusted logistic regression, full vaccination was not significantly associated with increased adverse events through 90 days, relative to unvaccinated patients. DISCUSSION Full severe acute respiratory syndrome coronavirus-2 vaccination was not associated with an increased rate of key adverse events relative to unvaccinated individuals among patients with inflammatory bowel disease.

Abstract
Since 2019, COVID-19 has plagued the world with its unfortunate death toll; however, with the introduction of multiple COVID vaccines, mortality and morbidity rates have severely declined. There have been misconceptions surrounding these vaccines, and at the same time, many documented conditions precipitated by the vaccines. This case highlights a speculated relationship between new-onset Latent Autoimmune Diabetes in Adults (LADA) (presenting with diabetic ketoacidosis) and the COVID-19 vaccine. There have been articles suggesting the precipitation of diabetic ketoacidosis /hyperosmolar hyperglycemic syndrome, as well as new-onset diabetes mellitus (DM) with the COVID-19 vaccines but no documented link between LADA and the vaccine. The endpoint of this case is not only to highlight a newfound side-effect of the vaccine but also to urge primary care providers and physicians to closely monitor glucose levels and patient's A1C after vaccine administration to prevent the formation of these hyperglycemic crises, as well as to consider autoimmune conditions in the differential diagnosis post-vaccination.

Abstract
For the primary prevention of coronavirus disease 2019 (COVID-19), there are currently four different vaccines available in the USA. These are Pfizer (messenger RNA [mRNA]), Moderna (mRNA), Novavax (recombinant protein), and Jansen/Johnson & Johnson (adenoviral vector). All individuals should get vaccinated, and the Centers for Disease Control and Prevention (CDC) has provided comprehensive guidelines on recommended doses, their frequency by age group, and vaccine types, all discussed in detail in this article. Vaccines are a critical and cost-effective tool for preventing the disease. Prior to receiving a vaccine, patients should get adequate counseling regarding any potential adverse effects post vaccination. Appropriate safety precautions must be taken for those more likely to experience adverse consequences. Healthcare professionals should be aware of the symptoms, indicators, and treatment of any adverse event post-vaccination. We have provided a comprehensive review of the different characteristics of COVID-19 vaccines available in the United States, including their effectiveness against various variants, adverse effects, and precautions necessary for healthcare professionals and the general population. This article also briefly covers COVID-19 vaccines available worldwide, specifically their mode of action and effectiveness.

Abstract
BACKGROUND Many studies show significantly improved survival after R0 resection compared with R1 resection in pancreatic adenocarcinoma (PAC); however, the effect of neoadjuvant chemoradiation (NACRT) on this association is unknown. OBJECTIVE The aim of this study was to evaluate the prognostic significance of positive surgical margins (SMs) after NACRT compared with upfront surgery + adjuvant therapy in PAC. METHODS All cases of surgically resected PAC at a single institution were reviewed from 1996 to 2014; patients treated with palliative intent, metastatic disease, and biliary/ampullary tumors were excluded. The primary endpoint was overall survival (OS). RESULTS Overall, 300 patients were included; 134 patients received NACRT with concurrent 5-fluorouracil or gemcitabine followed by surgery, and 166 patients received upfront surgery (+ adjuvant chemotherapy in 72% of patients and RT in 65%); 31% of both groups had a positive SM (+SM). The median OS for patients with a +SM or negative SM (-SM) was 26.6 and 31.6 months, respectively for NACRT, and 12.0 and 24.5 months, respectively, for upfront surgery. OS was significantly improved with -SM compared with +SM in both groups (p = 0.006). When resection yielded +SM, NACRT patients had improved OS compared with upfront surgery patients (p < 0.001). On multivariable analysis, +SM in the upfront surgery group (hazard ratio [HR] 2.94, 95% confidence interval [CI] 2.04-4.24; p < 0.001) and older age (HR 1.01, 95% CI 1.00-1.03, per year; p = 0.007) predicted worse OS. +SM in the NACRT group was not associated with worse OS (HR 1.09, 95% CI 0.72-1.65; p = 0.70). CONCLUSION Patients with a positive margin after NACRT and surgery had longer survival compared with patients with a positive margin after upfront surgery. NACRT should be strongly considered for patients at high risk of R1 resections.

Abstract
Vaccine-related erythema nodosum is uncommon, especially after the coronavirus disease 2019 (COVID-19) vaccine. This study presents the first case of the Pfizer vaccine associated with erythema nodosum. A 22-year-old healthy woman presented with a five-day history of several red painful areas with swelling in the lower extremities that started one day after receiving the first dose of Pfizer vaccine. Past medical history, laboratory investigation, and chest radiograph revealed normal results. Erythema nodosum is an immune reaction that manifests as multiple, painful nodules commonly seen on the shin that resolved spontaneously two to eight weeks after the onset. In the absence of laboratory and chest radiograph abnormalities and shortly after receiving the Pfizer vaccine, vaccine-related erythema nodosum is the only possible explanation.

Abstract
"Necessity is the mother of invention:" An adage was brought to life with the emergence of the mRNA vaccine against the backdrop of the foreboding and mercurial COVID-19 pandemic. Considering a negligible adverse-effect profile and a break-neck manufacturing speed, it shone bright as the ideal vaccine candidate. However, "all that glitters is not gold," as was evidenced by the significant reactogenicity, a host of multi-systemic side-effects, that are being reported by the vaccine recipients; which is palpably resulting in a shift of emotions for the vaccine, accounting for vaccine hesitancy. Anaphylaxis, antibody-dependent enhancements, and deaths, comprise the most serious side-effects, albeit occurring in sparing numbers. Storage and transportation require fastidious temperatures, rendering it substantially inaccessible to a country like India. The biggest jolt, however, was the unfolding of the biases in reporting vaccine efficacy, as only the attractively high numbers of the relatively equivocal relative risk reduction were reported while keeping at bay the meager numbers of the more forthright absolute risk reduction. Notwithstanding the fallacies, the mRNA vaccine still promises hope; and with the right precautions and finesse, can be potentiated, as "a watched pot never boils."

Abstract
Introduction Vaccinations against COVID-19 were licensed with limited testing assurances to the public triggering a widespread hesitancy around expected adverse reactions. Limited data was reported from Arabian Gulf countries on vaccine adverse effects. Objectives This study looked at the rate of reporting at least one side effect post-COVID-19 vaccination and its associated factors (sociodemographic characteristics, clinical condition, and type of vaccines). Additionally, questions about safety and willingness to recommend them were included. Study design Phone interviews on post-COVID-19 vaccination adverse effects were utilized to record responses related to reporting at least one side effect post vaccinations across the studied variables. Data collection continued for two months (from 1st March to 30th April 2021). Methodology Participants were adults (Omani citizens and non-citizens) who received AstraZeneca (AZ) or Pfizer (PF) vaccines from primary care facilities in Muscat and were randomly selected from the health information system. Responses were saved in a bespoke Google form/questionnaire. Chi-squared tests were utilized to determine potential factors associated with the dependent variable. Results A total of 753 participants completed the phone interviews. The mean age was 52 (3.5), males (54.1%), and 65.1% were Omanis. Hypertension (39.7%), diabetes (34.1%), and asthma (16.7%) were the commonest comorbidities. AZ and PF were administered to 78% and 22% of the participants. Of them, 49.8% reported at least one adverse effect post-COVID-19 vaccination. The proportion of participants with at least one adverse effect was significantly more in individuals who were younger, females, with more than secondary education, and employed (p value < 0.001, 0.01, <0.001, and <0.001, respectively). There was no severe reaction (anaphylactic shock) to the vaccines, and most adverse effects were mild-moderate. The proportion of individuals who reported adverse effects were higher with AZ vs PF (53% vs 38.6, p = 0.001). The most common reported localized adverse effects were pain and tenderness (28.3% and 12.1%). Fever and body aches were the commonly reported systemic adverse effects (33.5% and 29.2%). The safety of COVID-19 vaccines was well perceived, and most participants were willing to recommend them to others. Conclusions The current study confirms findings from existing literature on the mild to moderate adverse effects of AZ and PF vaccines. Despite the subjective nature of this study, it is reassuring that the studied COVID-19 vaccines can be administered safely. However, more longitudinal studies are needed to test their efficacy in disease prevention.

Abstract
Humanity is experiencing a catastrophic pandemic. SARS-CoV-2 has spread globally to cause significant morbidity and mortality, and there still remain unknowns about the biology and pathology of the virus. Even with testing, tracing, and social distancing, many countries are struggling to contain SARS-CoV-2. COVID-19 will only be suppressible when herd immunity develops, either because of an effective vaccine or if the population has been infected and is resistant to reinfection. There is virtually no chance of a return to pre-COVID-19 societal behavior until there is an effective vaccine. Concerted efforts by physicians, academic laboratories, and companies around the world have improved detection and treatment and made promising early steps, developing many vaccine candidates at a pace that has been unmatched for prior diseases. As of August 11, 2020, 28 of these companies have advanced into clinical trials with Moderna, CanSino, the University of Oxford, BioNTech, Sinovac, Sinopharm, Anhui Zhifei Longcom, Inovio, Novavax, Vaxine, Zydus Cadila, Institute of Medical Biology, and the Gamaleya Research Institute having moved beyond their initial safety and immunogenicity studies. This review analyzes these frontrunners in the vaccine development space and delves into their posted results while highlighting the role of the nanotechnologies applied by all the vaccine developers.
