There is a massive lack of understanding on both sides of how infections happen, why covid is sometimes so mild and sometimes so severe and how well a vaccine will protect you. I do not think the vaccine is worth it for most younger people especially if they can obtain antivirals. But if you are young and healthy and get immunized you are HIGHLY unlikely to pass covid on to someone else. That is because people with high viral loads are the most likely to pass the disease on, and people who get the vaccination (or have had the disease) and still contract the infection are likely to have only very low viral levels. This makes it hard to spread the virus onto someone else and even less likely to spread a severe case. Severe cases are associated with a high level of exposure to the virus. We are thinking of infections in a binary way (got it / don’t got it) but we should be thinking of them in a ‘continuous’ quantity-based way. People who inhale small amounts of virus may not get the infection or may have such a minor infection that they have no symptoms and they are unlikely to spread the virus. People who inhale large amounts of virus get very sick and often die. Its quantity of virus. We shouldn’t worry about vaccine leakage. It doesn’t matter if small quantities of virus get passed around. (((Their))) arguments about vaccine leakage usually revolve around mutations and variants developing, but virologists have shown that this a very slow mutating virus. The cataloged mutations are minor and will not significantly infect people who are already immune from previous exposure.
