Your physician. Not hacker news.
I am absolutely able to read a study and interpret its results. I read the phase 3 trial results for Moderna and was satisfied that it was excellent evidence for getting the vaccine. I’m not yet aware of any booster studies outside of antibody counts post booster. It would be nice to have an idea of how much my risk of Covid drops and for how long, but I’m not sure if we have evidence collected on that yet.
