The Moderna Covid-19 vaccine, for example, is a two dose series, not a 365-dose series. The reported odds of suffering anaphylaxis to the Moderna Covid-19 vaccine are based on the 10 cases of anaphylaxis that occurred after 4,041,396 first doses of the Moderna Covid-19 vaccine were administered from December 21, 2020 through January 10, 2021. The CDC MMWR did report 43 allergic reactions that didn’t qualify as anaphylaxis and occurred within a day of receiving the Moderna Covid-19 vaccine. Sixty percent of the people who had such reactions already had a history of allergies or allergic reactions to other foods or drugs. Does all of this mean that the Moderna Covid-19 vaccine is safer than the Pfizer/BioNTech one?
