Fun fact, among George Washington's first actions as general of the colonial armies was to issue a lockdown preventing troops from going to water supplies due to the risk of spreading smallpox.
As the war effort continued Washington quietly vaccinated his troops (or more accurately infected them through putting puss into the skin which was less lethal then airborne infections) to prevent smallpox from decimating his army.
So, whatever other reasons there may be, lockdowns and forced vaccination (although in Washington's case it was forced in a literal sense as deserting was a no-no, and it was not just a "you can't go to the gym" kind of thing) are not some strange new infringement on American rights. In fact, the country very likely would never have existed without those things.
