Should children be vaccinated against COVID-19?

Petra Zimmermann et al.

Summary: The debate over whether all children under 12 should be vaccinated against COVID-19 continues, with considerations including the relatively low risk of acute COVID-19 in children and the complexity of weighing the risks and benefits of vaccination. Other factors to consider include protection from long-term consequences, population-level impacts, vaccine supply, cost, and avoiding quarantine measures. Ongoing evaluation is needed due to the emergence of new variants of concern.

Summary: The study found that despite a decline in total S-specific antibodies in some patients, neutralizing antibody titers could remain at a similar level for an average of 98 days. The immune response to natural infection differs from that of vaccination, with natural infection inducing a more robust humoral immune response in unexposed subjects.
