All 50 US states (along with several territories and DC) require mandatory vaccination for children entering public (and frequently, private) schools. This system has essentially ended most vaccine preventable diseases in the USA, including measles, polio, chickenpox, and many others.
Broad vaccination is considered one of the 10 greatest achievements in public health. Vaccines should probably be number 1 on the list. Overall, the immunization mandate has established a strong herd effect, which has generally ended transmission of these diseases.
Even though vaccinating children before they enter school is mandatory, there are ways around it, if you choose. Every state allows medical exemptions, which is based on a proven risk for a child to not be vaccinated with one or more vaccines. For example, some vaccines are produced in chicken eggs, and a tiny percentage of children are allergic. Medical exemptions are absolutely critical to the well being of the child, and no pro-science (pro-vaccine) writer or researcher would be opposed to those types of exemptions.
Furthermore, most states have vaccine exemption laws which allows personal belief exemptions (PBE). These PBEs fall into one of two groups–religious exemptions, that is, the parent “claims” that their religion is opposed to vaccines; or personal exemptions, which are simply based on the fact that the parents are opposed to vaccination for whatever reason that hits their brain after 20 minutes of Googling “facts.”
Most states allow both types of exemptions, some only allow religious exemptions, and one state, Mississippi, allows only medical exemptions. As a progressive, there is little positive I can say about Mississippi, but this is a major positive. So congrats Mississippi for caring about children, at least in this one important way.
