A related question seems to keep popping up: How long after receiving the second COVID dose are you immune, or fully protected, against the virus? โRegardless of which vaccine you get, you wonโt reach full protection until two weeks after your second or final dose. Thatโs about how long it takes your immune system to mount an antibody response to the vaccine.โAdRemember, three vaccines are currently being distributed: Moderna, Pfizer and Johnson & Johnson. The first two require two doses -- and Johnson & Johnson is the only one thatโs just a single dose. This is why the second dose is so important, and why weโre so diligent about scheduling you for your follow-up shot.โAdDonโt skip that second dose.
