Are the side effects worse after the second dose?
Both Pfizer and Moderna require an additional “booster” dose after the first dose (21 days for Pfizer and 28 days for Moderna) to allow for the best protection. Efficacy after the first dose is reported around 50-52% and that increases to 95% after the second dose.
This is, in part, due to enhanced immune responses after the first dose. The symptoms outlined above have also been reported after the second doses of both vaccines, sometimes with increased frequency and sometimes, more pronounced symptoms. This is again related to your immune system doing its job to impart protection.
Both Pfizer and Moderna Products are safe and efficacious with 95% efficacy. There have not been identified differences in the products in that regard, so one is not superior to the other. Also note, we do not choose what vaccines we are given, that is determined on a State distribution level, therefore, you cannot CHOOSE which vaccine you get (nor can we!).
