I knew this. I have no idea why they decided on a 3 week gap but it was and is a huge strategic and medical error.
I haven’t gotten my second dose yet as I am planning to space them at least 6 to 8 months apart.
Also, as numerous docs/scientists told us last year....you do NOT attempt to vaccinate OUT of a pandemic.
That is where we should’ve all pushed back, on this, last year. Including to dear Pres Trump, God bless him.
Actually, I think the 3 week gap was initially a minimum. They didn’t want people getting the 2nd does before that. But then for some reason, it was adopted as the suggested time, probably in a hurry to get everyone vaccinated
