There has been no forced gubmnt vaccine requirement for simply being a citizen here.
If you want to partake of certain activities in certain situations, sure, a vaccine of some kind may be required for you.
I can’t imagine that the Supreme Court would back up our President in holding down citizens and injecting foreign substances into their bodies even if he has determined, in his infinite wisdom, that it is for their own good. I am grateful our constitution prevents such egregious overstep of our governmrnt.
