Philip I could argue vaccines, evidence and what many very excellent doctors say about them, but as you have already pointed out, we are getting off topic and so I will not continue to discuss the issue of vaccines out of respect for the focus of this forum. I am sure that you will do the same. I am sure that people who really want to know will do their own research through credible groups who hold both sides of this scientific topic. At the core of science is looking at competing theories or perspectives, verifying the data and determining which aligns with the data the best..
I do appreciate that you have care for the welfare of people, I assure you that I do too.
