Even more precisely three weeks is the minimum recommended for optimal efficacy. If one has to wait a bit longer it will not adversely affect the second shot’s efficacy.From what I've read/heard, the optimal wait between shots is three weeks. Good luck in your quest!
Howard:I am finally getting my shot later this morning at a High School, wish me good luck.
Single shot, correct? When talk of vaccines heated up late last year and early this year, the idea of a single shot would have been my choice, but when I was able to get Moderna (2 shots), I went with it.I understand J&J is with our local hospital, getting mine tomorrow.
