It does provide protection, but what we don't know is:

2) How it impacts future vaccination efforts
(As well as a slew of other things)
If it was just #1, I'd be with you. If we give a big chunk of the population a vaccine which lasts 6 months and makes them unimmunizable, we've changed a serious problem into a serious, serious problem.
- zaroth 6y ago> ...and makes them unimmunizable... Is there any scientific basis for this hypothetical?
- murgindrag 6y agoYes. It's pretty common for vaccines. One mechanism: If you have a vaccine designed to deliver a spike protein (without a virus) surrounded by a carrier. The body learns to destroy the carrier. On future doses, the body recognizes the carrier, and the vaccine is destroyed before the body can react. Of course, a vaccine with a different carrier won't be affected by this mechanisms, but there are many other mechanisms as well. I'm not an expert, and I don't know all of them. I'm not sure science knows all of them either, for that matter. There have even been instances of vaccines making diseases worse too (actually, viruses not too dissimilar to COVID19). And there are a bunch of other possibilities. I'd buy the basic premise of giving each person one dose for giving everyone imperfect immunity if not for these sorts of complications. I'd rather just wait a few more months than risk a small (but definitely non-zero) chance of something really, really bad.
