My god the insanity here is wildly out of control. As he has pointed out, vaccines don't stop transmission in any way, so people's individual choices about whether to get vaccinated or not is absolutely not making them "killing people" or "murderers". If you really want to go there, consider that people are definitely being killed by the vaccines themselves, that is proven beyond doubt now. So it's easy to turn that around and say those trying to push vaccines on people who don't need them are the "murderers".
1. Vaccines do stop transmission because they make it less likely your internal systems will get infected
2. Vaccines also prevent hospitalizations very effectively
3. Known side effects from the vaccine are very, very low. Much lower than the risk of getting COVID, for the same health outcomes.
4. Getting COVID (the bad outcome caused by the virus) has some chance at Long Covid. The vaccine reduces this because it makes it less likely you get the syndrome after infection.
