I’m not trying to call anybody out, but it’s worth noting that there are immunologic and clinical data that indicate the AZ vaccine is more effective if you delay dose 2, but for Pfizer it’s more like “immunologists think it should be fine to delay”.
Yesterday there was a widely cited thread indicating the US was considering doing this. I haven’t seen any evidence outside that thread that this is happening, but as a clinical trialist I think it’s incumbent upon advocates to provide a stronger rationale than expert opinion.
Ultimately this would amount to a massive unconsented clinical trial on the public! It makes me extremely leery. That’s it, that’s my piece.
Much more detail on both AZ and Pfizer in this very good thread: https://twitter.com/dgurdasani1/status/1344727697524740101
