Just yesterday after receiving my 2nd Pfizer vaccine I was wondering how long the immunity was going to last

 So, I was pleasantly surprised Easter Sunday to realize other people were also asking this question which is a good one, especially if you have just gotten or are soon going to get your vaccine(s).

The only  single shot that doesn't need the level of freezing that the other ones do is Johnson and Johnson. But, because it is easier to keep effective during worldwide travel this likely will be the one most nations get, especially third world nations.
