All the people screaming hysterically AGAINST anyone who questions the vaccine are a big cause in why people don’t trust it. In a society where people can not talk or have questions without hysterics you are asking for conspiracy theories’ and mistrust to grow.
I am vaccinated and 10000000% pro vax. Even so I will admit that twice when arguing with anti-vaxxers they caught me repeating baloney that I believed because I had been told that by reputable sources about the safety of the vaccine. I didn’t change my mind but I did start to understand the resistance. Very well.
Stop the exaggerated hysterics. ( a healthy twenty year old is very unlikely to die if they don’t get vaccinated) Acknowledge that the anti Corona vaxxers may be right about some points and adre them honestly . Then you will have a much better chance of convincing them that the vaccine is a lot safer than not taking it.
