@Bokanovsky said, sounds like you got a loose screw in your head. What makes you think you own her body and you can over impose your beliefs unto others?
Not everyone believes this vaccine is the answer and especially given it's your own body in question, what makes you think she should lose her body sovereignty?
If this is very important to you, I respect that, but if she is not on the same page then you may not have the same values and principles. In which case, do walk away and be with someone that shares those things with you and let her be with someone that shares hers.
I'll leave you with this, your beliefs don't make you right. I am not pro-vaxx, and have strong beliefs on covid-19 and what is happening, but I still know I can be wrong. But I do know this is my body (which is a temple) we are talking about, I should not have to be forced to use it as a guinea pig or lab rat tool. Your reality is your reality, not someone else's.
Last but not least, if you are vaccinated, why do you care? You are "protected" aren't you? Isn't that the whole point? If you are concerned about being infected even after taking the "vaccine" then I assume you don't genuinely believe in its effectiveness. Is that correct?
