Don’t get a COVID-19 vaccine at the same time as other vaccines
Wait at least 14 days after your COVID-19 vaccine before getting any other vaccine, including a flu or shingles vaccine. Or if you have recently received any other vaccine first, wait at least 14 days before getting your COVID-19 vaccine.
However, if you do get a COVID-19 vaccine within 14 days of another vaccine, you do not need to be revaccinated with either vaccine. You should still complete both vaccine series on schedule.
