I'm sure there are a number of factors worth considering here which could account for some of the data, but if vaccines were truly as efficacious as governments and pharma companies have been suggesting then given the success of the UK vaccine rollout can we honestly say this is the trend we would expect to see? I completely accept this isn't proof that vaccines are not effective at managing the pandemic, but the fact data like this is so hard to justify within the context vaccines being highly efficacious it's a bit concerning, especially since it's not like we have much of a choice but to get it here in the UK. My partner is getting her booster today, not because she wants to or feels she needs to (also had a prior infection) but because she feels pressured by government policy. Then just last night I was out shopping and a ~30 y/o guy in the store was complaining about having chest pain since getting his booster, and I've had many similar experiences over the last few months. I hate brining up anecdotal evidence because I know it means nothing, but what I'm seeing with my own eyes in the real world and in the data right now is so hard for me to understand within the context of a safe and effective vaccine. If the data was clear then fair enough, but it's far from clear. I don't want that to be the case, but it is. What's worse is that every time I've brought this up the response I've received has basically been dismissal, "must be some explanation, vaccines are effective".
