Maybe something important came up, and you had to miss your second COVID vaccine appointment.  Don’t panic if you missed your designated second vaccine dose.  The recommended interval between Pfizer vaccines are 21 days apart.  The recommended interval between the Moderna vaccines are 28 days apart.  This means that it’s optimal to get your shot in that interval.  But if you couldn’t make it and you missed it, and your new challenge is to get back into the scheduling window… as long as you are able to get your second dose within 6 weeks of your scheduled date – you are fine according to the CDC.  The new goal would be to get your second vaccine as close as possible to the original date you were scheduled to: 21-day interval for Pfizer and 28-day interval for Moderna. 

That said, it is unknown how effective the vaccine will be when it is delayed beyond the 6-week interval.  Contact your vaccine distributor for scheduling/re-scheduling your second dose if you have missed that date.

Lastly,  Please be sure and take a picture of your COVID vaccine card so you always have a picture on your phone in case you lose it.
