Key takeaways
Spikevax (Moderna) and Comirnaty (Pfizer) are both mRNA vaccines used to prevent COVID-19 infection. They are similar in that they both help protect people from severe COVID-19 and are FDA approved for people 65 years and older. However, they differ in their age approvals and dosing. Spikevax is approved for children as young as 6 months, while Comirnaty is approved for children ages 5 and older. Both vaccines have common side effects like pain at the injection site and tiredness, but they typically resolve after a few days.
