Summary: Studies found no increased risk of hematological abnormalities after CoronaVac vaccination, but an increased risk of leukopenia was observed shortly after the second dose of BNT162b2. However, the incidence was much lower than following SARS-CoV-2 infections. The benefits of COVID-19 vaccination still outweigh the risk of hematological abnormalities.

Summary: The study found that people in Jordan experienced more side effects with the AstraZeneca vaccine followed by the Pfizer vaccine and the least one is the Sinopharm vaccine. These side effects include symptoms such as pain at the injection site, fatigue, headache, and nausea, with most individuals not considering them severe.

Summary: Variables such as increased waist circumference, smoking, hypertension, and longer time elapsed since vaccination were associated with lower antibody titres following COVID-19 mRNA vaccination. This suggests that individuals with central obesity, hypertension, and smoking may benefit from earlier vaccine boosters or different vaccination schedules to ensure adequate immune response.

Summary: This retrospective study evaluated the determinants of serological protection in vaccinated healthcare workers and found that 99.5% of them developed protective antibodies that were maintained for as long as 250 days after the second dose of the BNT162b2 vaccine. The antibody titer observed at the second evaluation was significantly related to the primary response, evaluation time interval, and previous history of SARS-CoV-2 infection. Importantly, none of the study participants contracted severe COVID-19 during the observation period.

Summary: This study compared the extension and severity of self-reported side effects of seven COVID-19 vaccines in the Mexican population and evaluated the association of vaccine type, sex, age, comorbidity, and history of allergies with the extent and severity of side effects. The results showed that ChAdOx1 and Gam-COVID-Vac had the highest rate of side effects in the first dose, while mRNA-1273 had the highest rate of side effects in the second dose. Young age, female sex, comorbidity, and history of allergies were associated with greater extension and severity of side effects.

Summary: This study aimed to investigate potential side effects of COVID-19 vaccines, associated risk factors, and compare three vaccines available in Iraq. Results showed that symptoms post-vaccination were mostly mild to moderate, with fatigue, injection site reactions, fever, myalgia, headache, and chills being the most reported. Factors like younger age, female gender, history of COVID-19, comorbidities, and receiving the AstraZeneca vaccine were associated with higher risk of adverse reactions.

Summary: Vaccines are crucial tools in public health, with the COVID-19 vaccines expected to have a positive impact globally. While serious allergic reactions are rare, it is important to consider their mechanisms, clinical implications, and potential causes, as well as to review implications for individual diagnosis, management, and vaccine manufacturing for future research.

Summary: The study revealed that pregnant and lactating women have a high level of COVID-19 vaccine acceptance, but they tend to prefer delaying their vaccination. Factors such as pregnancy trimester, education level, employment status, and previous live births were found to be significant determinants for COVID-19 vaccine acceptance among this population subset.

Summary: The study assessed the reactogenicity and immunogenicity of Pfizer and AstraZeneca COVID-19 vaccines among adults in Saudi Arabia. It found that Pfizer vaccine recipients reported fewer vaccine-related complications compared to AstraZeneca vaccine recipients, and the presence of antibodies against the SARS-CoV-2 spike protein may be influenced by factors such as health status and age.

Serious vaccine adverse effects were rare in this real-world cohort.

Summary: Virus-specific antibody levels after a single dose of the BNT162b2 vaccine in individuals previously infected with SARS-CoV-2 are similar to levels after two doses of the vaccine in infection-naive individuals. Post-vaccine symptoms were more prominent for those with prior infection after the first dose, but symptomology was similar between groups after the second dose.

Summary: After vaccination with ChAdOx1 nCov-19, rare immune thrombotic thrombocytopenia can occur due to platelet-activating antibodies against PF4, resulting in various thrombotic events. Most patients in this case series were women, with fatal outcomes such as cerebral venous thrombosis and intracranial hemorrhage. Additional studies are needed to further investigate and understand this phenomenon.

Summary: The development of safe and effective vaccines against COVID-19 is crucial in the fight against the pandemic. Although some thrombotic adverse reactions were associated with the Oxford-AstraZeneca vaccine, the European Medicines Agency affirmed the vaccine's safety and effectiveness, with the benefits outweighing the risks. Conducting further analyses based on more detailed thrombotic adverse event reports may help evaluate causality with higher specificity.

Summary: After analyzing 19 relevant articles, it was concluded that among the eleven vaccines, Pfizer-BioNTech (about 95%), Moderna (about 94%), and Sputnik V (about 92%) showed an efficacy greater than 90%, while Oxford-AstraZeneca was only about 81% effective. Additionally, Moderna, Sputnik V, and Oxford-AstraZeneca also reduced the occurrence of severe adverse reactions.

Summary: The study compares the safety, tolerability, and reactogenicity of different COVID-19 vaccines among various recipient groups. Those who had a prior COVID-19 infection were found to have an increased risk of vaccination side effects, with mRNA vaccines causing milder systemic reactions but more local reactions compared to viral vector-based vaccines.

Summary: Adults receiving heterologous COVID-19 immunisation with mRNA or adenoviral-vector vaccines had higher reactogenicity rates, especially among those aged over 50, women, and individuals with prior symptomatic/confirmed COVID-19. Those who received heterologous schedules after severe first-dose reactions may have lower reactogenicity after the second dose, depending on the specific combination of vaccines used.

Summary: The study found that the most common side effects reported by participants in the Aseer region of Saudi Arabia after receiving the COVID-19 vaccines were fever, myalgia, malaise, muscle and joint pain, and headache. Symptoms were more common in males than in females. Despite a certain infection rate, the side effects of COVID-19 vaccines were consistent with the manufacturers' data.

Summary: The survey conducted among healthcare professionals who received COVID-19 vaccines in Jordan showed that around 18% and 31% reported no side effects after the first and second doses respectively. Most of the side effects were local, while systemic side effects like fatigue, myalgia, headache, and fever were more common after the first dose, particularly associated with the AstraZeneca vaccine and age <= 45 years. No serious side effects were reported, indicating that the side effects of COVID-19 vaccines in Jordan are similar to what have been known before. Further studies with larger sample sizes and longer follow-up periods are needed to monitor potential serious and long-term side effects.

Summary: This study aimed to compare early post-vaccination symptoms in individuals who subsequently tested positive or negative for SARS-CoV-2. The findings suggest that it is challenging to differentiate post-vaccination side-effects alone from early COVID-19, and individuals presenting with systemic symptoms post-vaccination should be tested for SARS-CoV-2 or quarantining to prevent community spread.

Summary: This study systematically reviewed the safety data from published COVID-19 vaccine trials, indicating that most reactions were mild to moderate, while a few were severe, and all reactions resolved within 3-4 days. COVID-19 vaccines may be safe, but long-term post-marketing surveillance in high-risk vulnerable populations is needed.
