"Administration of 2nd dose within 4-day grace period (e.g., day 17-21) considered valid"
and then
"If >21 days since 1st dose, 2nd dose should be administered at earliest opportunity (but no doses need to be repeated)"
without further explanation, seems to give mixed signals
- stmw 6y agoI think what they're saying is that 17-21 days after is valid, after 21 is not "valid" but acceptable. So for example someone receiving a 2nd dose on day 23 wouldn't be counted to as part of a clinical trial but is not forbidden and no need for 3rd dose?
