Of course, this study doesn't include data for every single person who's received a booster shot so far because the V-Safe survey is voluntary, so there may be some patterns in side effects that the study can't pick up. About 22% of Pfizer recipients and 35% of Moderna recipients reported side effects so severe they couldn't perform their daily activities, which was slightly less than the number of people who reported that after the second dose.īased on this data, the researchers conclude that side effects after the booster shot are likely to be similar to those seen after the second dose of the COVID-19 vaccine. But they also reported having fewer systemic reactions (such as fatigue and headaches) after their third dose than the second. More people reported having reactions at the injection site after their third dose than their second, according to the data.
