Cool cool. Now take the time and be patient and try to teach someone you know that refuses to get the vaccine. I'm simply explaining the type of people you are dealing with when you get all agitated over those evil "anti vaxxers". And if you can't get through to them, oh well, you tried. They didn't live your life to be as open to learning new things. I personally didn't learn about the chicken pox vaccine until a few years ago. I also had no idea what an mrna vaccine was before covid. But not everyone is actually out trying to learn things and think critically. Many people just do as they are told, or they rebel against authority. If only everyone was the same....
