I just did a school paper on the subject of vaccinations and I agree with you to the fullest. Multiple studies have been done to discredit the claim that vaccines cause autism, so I really don't see that as a good argument for anti-vaxxers. I didn't think of the vaccination day thought and I think that is a good idea.
I do believe vaccinations should be implemented bc as you put it involves the whole community. For my paper, I suggested that if parents choose not to vaccinate their children, fine it's their choice regarding their kid, but as them not getting vaccinated involves everyone in the community, I suggested that the unvaccinated kids not be allowed in public property, such as public schools.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
