Not all vaccinations are created the same. In the case of covid, it's going to keep mutating and be a part of the yearly flu forever. It's not like polio or chickenpox which are one and done. Or tetanus which needs a booster every 10 years.
Also, if someone had Covid why should they get vaccinated?
This anti-vax label is being used to silence people and to control how people live their lives. There are good reasons not to get vaccinated. It does not make somebody anti-vax to believe that the government has no authorities to dictate what vaccinations you must have to live life.
