The parents have the right to choose what they put in their children’s bodies. There are insufficient studies done on the effects of so many vaccines at the ages given. Placebo groups are allowed to have the vaccines once the “studies” are over so there’s no way to track long term effects. There’s also little to no data on these vaccines on children with different genetic defects. There’s also no data on various vaccines given together with other vaccines- the placebo is often another vaccine and not something neutral like saline.
