There have been requirements for years for certain destinations (e.g. where yellow fever is present). The issue now is whether employers can mandate an unapproved vaccine. My employer is mandating it for "return to the office". But I am already in the office. So instead I was sent a survey asking if I was going to get vaccinated or not (or if I already have). I answered that I am planning to. It was supposedly anomymous but who knows.
If it was sent by email it most definitely was NOT “anonymous”!
No survey is ever really anonymous.
I am sure your employer would jump at the chance to provide you with a signed document stating that they will 100% cover any and all medical expenses you should incur for the rest of your life that are related to the experimental injection they are coercing you to take. There also should be a death benefit of several million dollars payable to your next of kin in case of your likely death from it.
I would also make sure they are provided with a copy of the Nuremberg Code and 21 USC sec 360 also.
