The study you cite has some major issues. First, it's a proposed benefit based on a hypothetical mechanism, and not empirical data. Second, it does not indicate the likelihood of mutations that would be better treated by the vaccine. Third, it does not indicate how much more effective it would be, just that it's "possible".
Please stick to the topic and facts rather than being sneeringly dismissive. I'm not part of some bloc of anti-vaxxers, and open to changing my mind based on new information. In fact I've had covid AND I'm vaccinated, so the intent of my post is to spark discussion and get more data. Dismissing my post as FUD is ad hominem.
It can't be an ad hominem since I never said anything about you. Your post was FUD because you stated it very loosely and asked for hard data to refute it. You're quite likely right on infection providing better protection, but we neither have a hard confirmation of that (or you'd link it, right?) nor did you provide any support for "But beware saying that outloud." Not only there's ongoing research on differences (as we both provided), many people do say that outloud.
When I say "beware saying that outloud", it's a pointer to the nature of discussion on covid, which should be obvious to anyone paying attention - and that is that if you counter a prevailing or official narrative, you will be belittled and brushed aside, often without any conclusive data to back it up. The irony is thick.
That statement has multiple issues. What does "better" mean? Where did you look? How do you define immunity (risk, falloff time, etc.). There's a new paper every week comparing how the vaccination and infection responses are different. Generalising to one-dimensional "better" is not going to happen in serious publications.
We're still at the level of (for example) "Therefore, antibody immunity acquired by natural infection or different modes of vaccination may have a differing susceptibility to erosion by SARS-CoV-2 evolution." https://pubmed.ncbi.nlm.nih.gov/34103407/
There's certainly a lot of research around different responses and they're a single pubmed query away. "But beware saying that outloud" is just FUD.
