Liability with things such as this are very difficult to prove. Just like if Disney relaxes the mask rule and people spread the virus far and wide, even with contact tracing, you can’t really pinpoint such a dispersed population. This happened at Mardi Gras, rallies, Memorial Day Weekend, July 4th, Labor Day, Thanksgiving, Christmas, Channukah, Sturgis, Daytona Week and Spring Break. You know people have it but they return home to friends, families and neighborhoods spread across the entire country, or more.
Disney can’t relax because that is what happened to California. In fact the only thing still left closed was Disneyland. California has the highest number of cases And the highest number of deaths. Not only are there more contagious and constantly mutating strains out there, it is because people are just tired of it all and not using masks or social distancing is what keeps this at bay. Then throw in the people who won’t get the vaccine and could be carrying the virus around to their family and friends who have not been vaccinated.
And if you think masks don’t work, just look at this year’s flu season or serious lack thereof. Masks and washing hands frequently basically stopped the flu in it’s tracks.
The flu shot is whole other beehive of discussion.
There are court cases on vaccines such as the 2011 Supreme Court ruling on the DPT shot:

Then there’s the required meningitis shots for college kids or the required vaccines for kindergarteners. You’re required to wear a seatbelt in your car and you’re required to have a driver’s license and you’re required to get a social security number and you’re required to pay your taxes. This is all for the greater good of us as a people.
And don’t forget the 1905 ruling in Jacobson v. Massachussetts:

And then there are cases like these where private business can/cannot decide who they wish as customers:

As far as 4th wave, it is too soon to see where this is headed with the new, more contagious strains. But look at the 1918 pandemic and that was a bit different because the soldiers from WW1 were spreading it and it seems to have originated here, they think. Look at the 3rd wave in 1918 that came after the 2nd major wave. Our 4th wave may actually be the 1918 3rd wave. Look at the time spans, it’s a bit freaky:

If this so called 4th wave arrives and we're lucky enough to follow 1918 and get everyone vaccinated, there is a light at the end of the tunnel that is not an oncoming freight train!
