4) “Both Moderna's & Pfizer/BioNTech's vaccines require two doses. Reactogenicity is typically higher after a second dose. The side effects “mean the vaccine is working well. …means you had such a good immune response to the first dose and now you are seeing the effects of that”
5) “transient reactions should not dissuade people from getting vaccinated in the face of a pandemic virus that kills at least one in 200 infected, says @florian_krammer. Sore arms, fevers, and fatigue are “unpleasant but not dangerous,” he says. I'm not concerned about at all.”
