I found this report to be slightly confusing, but there was one table (I think it was Table 5) that showed that for many age groups, that the immune respose to covid after 40 weeks was actually significantly *weaker* than expected, compared to those who hadn’t received the vaccine at all. The idea is that the shot initially gives all age groups some degree of immunity, but that with every week that passed, that the immunity not only wears off, but that at a certain point, the shot seems to make you *more* vulnerable to getting infected. This would appear to be smoking gun proof that the shot *weakens* your immune system long-term.
I got the two Pfizer shots this past March and April, and so far, I’m not succumbing to opportunistic illnesses that would normally take advantage of a weakened immune system.
