Vaccine Side Effects May Include Fever and That’s Normal, Says Nurse Who Got It

Margaret Keenan, 90, who lives in Britain, became the first in the world to receive the Pfizer vaccine. The moment moved Britain’s minister of health to tears on national television. The FDA has found that immunity to coronavirus begins 10 days after receiving the vaccine, that the first shot is 55% effective, and the second boosts a person's immunity to 95%. The doses are supposed to be given three weeks apart. Some are saying they have experienced side effects, though that's to be expected.
