But this ship already sailed. You already have to have MMR to go to school. Healthcare workers already don't get a choice about having immunizations. Members of the armed services already had to accept vaccines. I was perfectly content with that five years ago, and I still am.
MMR is required to go to public school, and many private ones, but the public schooling option gets an asterisk. Homeschooling is an alternative in many places, and if you dig deep enough, I'm sure schools could be found that won't require MMR without further questions.
Note, I said the public schools require an asterisk. Here is why:
https://www.ncsl.org/research/health/school-immunization-exemption-state-laws.aspxAll 50 states have legislation requiring specified vaccines for students. Although exemptions vary from state to state, all school immunization laws grant exemptions to children for medical reasons. There are 44 states and Washington D.C. that grant religious exemptions for people who have religious objections to immunizations. Currently, 15 states allow philosophical exemptions for children whose parents object to immunizations because of personal, moral or other beliefs.
And many of those states have such provisions in their laws because they had people challenge the previous laws under 1st Amendment and other grounds in the past, so the exceptions exist to bring them in compliance with either court rulings(which may have been state level), or what their own interpretation of the constitution at the time dictated.
So yes, the vaccinations are
required, but in most states, "there is a waiver for that."
As to medical practitioners, nobody forces them to work in a hospital that has a vaccination mandate, plenty of medical practices exist where vaccination is not required in order to work for them. Many Libertarians would argue this is a combination of "employer choice" on setting standards for their employees, and "employee choice" on if they want to meet those requirements. Alternatives exist, so it isn't a civil rights concern.
The last man drafted into military service for the United States did so on June 30th, 1973. The last person on active duty/reserve status to enter military service by way of the draft retired in 2011. Needless to say, given the typical duration for draft enrollments, barring the person voluntarily re-upping, the US is probably going to be reaching 50 years without a person serving under conscription at either the end of 2024, or start of 2025.
Given the US Military is an "All Volunteer Force" this brings back the matter of "they could have simply decided to not sign up in the first place." Although there is something of an argument to be made about their not having signed up for Military Service with the idea of getting the Covid19 vaccine, given 4 to 6 year enlistment periods are common, Covid19 didn't even exist on the public's radar when many of those servicemembers last signed a contract with the Government.
...And the Government has a poor track record with carrying out dubious medical experiments on its own troops. If you go back to the 2002/2003 period, you'll also find plenty of active duty and reserve people fighting against getting the Anthrax Vaccine as well as the Smallpox Vaccine which had been brought back out of obscurity. So to say that the Covid19 pushback is unique to Covid19 isn't valid either.
