Actually you’re quite wrong. Parents have always had concerns with vaccinating children to some degree, but that concerned had waned due to a vigorous process of trials for safety. These new covid vaccines never went through the normal process of trials and safety. You’re conflating existing vaccines with long term studies and data, with vaccines without that, related to a virus that doesn’t effect children in the same way as adults.
"In 2014, a large measles outbreak swept through the Disneyland theme park in California, infecting over 50 people.
Several of the children who initially spread the disease were intentionally left unvaccinated by their parents.Outbreaks such as the one in the Disneyland theme park are becoming increasingly common due to falling vaccination rates. Undoubtedly, organized anti-vaccination groups have contributed to the drop in vaccination compliance and anxieties concerning vaccination. These groups often have a strong presence on social media and well-developed websites that attract people to their cause. But these sites have drawn very little critical attention. In order to combat falling vaccination rates, it is important for those supporting vaccination to be aware of, examine, and counter the claims of these groups."

The anti-vaxx movement has been extremely dangerous, and in the last few years, the World has seen the consequences of this. The anti-vaxx people are less concerned about the health and welfare of children, and more concerned about personal politics. It boggles my mind how seemingly intelligent people, such as yourself, can hold these bizarre positions.
