Whenever we are going to take a medical product or intervention it is always important to do your research much like we would do for buying a new car. We need to have informed consent and the freedom to choose whether we want to take the product or not. For vaccines here are the names of a few books that will help with that research -Turtles All the Way Down, Dissolving Illusions, Vax Facts and Aaron Siri's new book Vaccines Amen.
