Yes there's a big gray area of people's rights when they spreading disease but we also know that about %10 of the population are carriers of virus and vaccines don't work on them because they don't have an auto immune response and there's about another 10% that don't have a strong enough immune response to the vaccines so they actually get sick and spread the disease even more.
It's only logical to wonder if vaccines are truly effective at stopping diseases or maybe just basic hygiene would be just as effective and save us billions in wasted resources and medicine could focus more on cures for cancer or something else more productive.
There's also the chemicals and animal cells they put in the vaccines that make people wonder if big pharma has people's best interest in mind.
