They had to have parent’s consent. I had a polio shot, TB shot and smallpox. They were real vaccines, proven, tried and true. One shot, no boosters, and I don’t remember any bad after effects anyone had. Not the same as the phoney baloney crap their pushing today. Flu shots included. No one can tell me they know how a flu strain will mutate a year after they make the so called vaccine.
My dad was in the Navy. We traveled often to his next billet. Travel came with lots of vaccinations. I was spared the horror of going to the school cafeteria and returning with blood running down my arm. The vaccines I received were target against stable pathogens. That is not the case for the mRNA vaxx. That is/was a trashy product targeted against a rapidly mutating pathogen and harmful to the recipient. The dsDNA plasmids used to generate the mRNA template were not scrubbed from the mass produced "product". Nominally a billion were injected per recipient. They were replication competent and capable of transfecting many cells in the human recipients. Recipients became spike factories for many months following the injection. The spike is harmful on its own.
If I were a student in a school that was attempting to force vaxx me, I would be homeward bound, truancy be damned.
