Other studies have not come to the same conclusion, and the argument that vaccines lower your immunity to things other than what the vaccine is targeting, they've been pretty roundly rejected by science. A 2018 report in JAMA, quote, found no statistically significant differences in the level of immunity against non-vaccine targeted infections between their control and experimental groups. Yeah, of course. That might be what Alex is talking about, but I'm only guessing based on what's on his website. Yeah, yeah. There's another argument about vaccines lowering immunity that unsurprisingly comes from Andrew Wakefield. This one is basically that when you use vaccines, you put part of your immune response into hyperaction while the other part is not used and thus is weakened. The basic gist here is that he's saying that you get better immunity by dealing with things naturally, so you should get measles if you want to be immune to it, and if you take a shortcut of vaccines, it'll hurt your cell-mediated response-related immunity. This is nonsense and no one in the medical field takes it seriously. Yeah, that sounds like magic. Sincerely, I'm not sure what precise claim Alex is trying to make, but in trying to sort it out, it's not too hard to find two separate similar ideas, which are both bullshit, being pushed by luminaries of the anti-vax propaganda world, which are very easily debunked ideas. Vaccines do not lower your immunity, and no one is taking studies off the internet.
