US schoolteacher arrested after giving 17 year old student vaccination shot. (Not a licensed medical person.)
17 is just a year's wait until the student would have been old enough to get vaccinated without parental permission. The teacher should have told the student to be patient if the parents were not willing to allow a vaccination.
There's also the possibility that whatever was in that shot was not a real #COVID-19 vaccine, or that it was expired or adulterated.
