"What we've seen in studies is that the second dose does tend to have a little bit more potential to cause side effects than the first dose, but for people who have had COVID-19 infection previously and then recovered, they are at higher risk of having those same side effects after their first dose," she says. from https://www.msn.com/en-us/health/medical/strong-reaction-to-first-covid-19-vaccine-may-signal-previous-infection-experts-say/ar-BB1eJstT https://www.msn.com/en-us/health/medical/strong-reaction-to-...
