1/ Q: Does the COVID vaccine only last 90 days?!
A: No. There is really no reason to think that protection from the #vaccines wears off after 90 days. We know the vaccines last longer than 90 days. But we don’t know how long.

2/ The @CDCgov recently updated their #guidance about quarantining after an exposure & included some changes for people who have been vaccinated.
3/ They said that if you have a known exposure to someone who has #COVID & you completed your #vaccination series at least 2 weeks ago *but less than 90 days ago*, you do not need to quarantine.

4/ This update probably raises more questions than it answers.
1️⃣ Does that mean that a fully vaccinated person cannot get a mild/asymptomatic infection & pass it on to other people? And
2️⃣ Holy cats does this mean the vaccine “wears off” after 90 days?!?!

5/ The answer to the first question, about whether the vaccines completely prevent infection or just serious illness, is largely unknown rn. But signs point to yes--the vaccines likely do reduce the chances of asymptomatic transmission. We await more solid information here.
6/ As for whether the vaccines provide immunity for just 90 days?
There is NO indication that the vaccines quit working after 3 months, at all. 🗓

7/ Some of the people in the #Pfizer & #Moderna Phase 2 studies have been fully vaccinated for over 7 months at this point, & there is nothing suggesting that their immunity is weakening so far.
8/ We do not know exactly how long immunity from the vaccines lasts right now... it might be 1 year, 5 years, 10 years.
We DO know that it is more than 90 days.
We DO know that it is more than 90 days.
9/ We do not have any special insight into the internal workings of #CDC, but from what we can guess, the purpose of this update was to make the guidance for vaccinated people sync with the recommendations for people who have recently recovered from #COVID19.
10/ It seems to us like in the absence of information, CDC just picked 90 days as an arbitrary benchmark & wanted to make the recommendation the same for post-vaccination & post-infection.
We fully expect this guidance to be updated in the future.
