Now, I realize you're a white nationalist Republican who hates anything to do with education, so you won't learn from this, but it's really not a hard concept. I understand you're very low IQ, which is why you fall for Russian propaganda on 4chan and believe that watching Tucker Carlson makes you know more than doctors about medicine, but it's really not a hard concept. I know you can get this, man. If you still don't get it, you've admitted that you have severe autism along with your low IQ, so I am assuming you have a case worker for your mental impairment. Ask her about it.
Also, even if the vaccine doesn't prevent infection, it does a lot to make the case of covid much less severe.
Now, I know you Republicans don't like book lernin, but look up the definition of "ineffective" and "placebo" because it's obvious to everyone here that you don't know the word.
