We are in a pandemic. Have been since 2020. Vaccines have been available for the near entirety of 2021. You’ve had plenty of time to decide whether to get it or not. They had zero obligation to tell you ahead of time to get vaccinated if you’re planning on being in a large group of people. Nor did they need to give you time to get together with “like minded” others. They probably told you last minute so insanity such as that wouldn’t happen because it’s ridiculous and time wasting to try to help someone who wants to make a political statement with death or lifelong ailments.
If this is a religious thing as you claim, please quote the scripture(s) that prohibit you from being vaccinated. Also, have you received the MMR, polio, or other vaccines? If the answer to the latter is yes, just go get vaxxed already.
