I know quite a few who do not want to be vaccinated. All of them are between 20 and 40, in good health and are clear supporters of vaccination. They still do not want to be vaccinated against COVID-19. None of them is spouting any conspiracy garbage or anything else, but it is a personal decision based on the current data for this age group.
When you hear of hundreds of COVID cases from work, colleagues, friends and family and all are healthy again, then it is also difficult to argue for vaccination, because most just want to wait a little longer and/or are still cautious because possible long term effects of vaccination, which very likely will never occur. At the same time these people urge others, especially the elderly or sick, to get vaccinated against COVID asap.
I don't know what is so difficult to understand about the fact that some people don't want to argue AGAINST a vaccination, but that they just want to consider their personal risk. This is of course lower with vaccination, but for many under 50 an infection and severe consequences are extremely rare. Some people know this and are willing to take this very small risk of becoming infected unvaccinated, because then they would never have to worry about long-term consequences, even if they know that the chance is almost non-existent.
Sometimes it seems that some vaccinated people are still looking for confirmation that it was the right decision to get vaccinated (which in my personal opinion is never the wrong decision). If you're vaxxed, that's cool. So am I.
But all of that doesn't change the fact, that there are other people with their own personal reasons which have nothing to do with the conspiracy anti-vaxxers, who are complete morons ofc. In the process, many raging vaccinated people don't even notice that they are on the same level of stupid conspiracy anti-vaxxers, because they only see good and evil, me vs them or smart and dumb.
