We already have a cocktail of vaccines that we take for several different aspects of society. If you join the military, you're getting a cocktail of vaccines. If you work for the public education system, you typically are required to be vaccinated against a few different things. This is just an additional vaccine that will likely be mixed into the flu vaccine within the next year or two.

As I've had the vaccine in me since January with no ill effects, as have all my coworkers, I am not particularly concerned about the vaccine, no more than I've ever been concerned about the vaccine.

Whether or not private businesses enact their own standards for the right to use their services is not really something I can debate without attacking the rights of businesses, which I am typically loathe to do.

What line do you think I should draw? If a business does something I don't like, I don't use that business. There are several businesses I choose not to use because I don't care for their practices or requirements of use.

It may suck not having a Google robot turn my lights on and off in my house, but using that service would compromise my privacy, so I don't use the service, even though I sacrifice access to something I might otherwise want. That's the nature of business rights.
