Immunocompromised individuals are at a 6 to 11 times higher risk of developing herpes zoster compared to the general population, with hematopoietic stem cell transplant recipients facing the highest risk.

C-section deliveries may have long-term consequences on infant immunity, potentially affecting vaccine efficacy and increasing the risk of certain health conditions.

Recent research indicates that myocarditis and pericarditis occur solely in vaccinated children and adolescents, not in those infected with COVID-19. Despite higher risks of heart inflammation, vaccinated adolescents showed reduced rates of COVID-19 infection and severe outcomes.

This study from Cleveland Clinic highlights a counterintuitive trend where higher numbers of COVID-19 vaccine doses could lead to increased risk of infection, underscoring the complexity of immune responses and vaccine effectiveness over time.

Recent systematic reviews suggest a subtle increase in NMOSD and MS risks post-COVID-19 vaccination, primarily affecting genetically susceptible individuals.

Recent research indicates a rise in cancer mortality following the third dose of mRNA COVID-19 vaccines, especially in types linked to estrogen sensitivity. This underscores the need for ongoing surveillance and research into the long-term effects of mRNA vaccines on cancer progression.
