Hello, hope it's okay to post this here. My denomination is... something that's pretty much Baptist, but with a few tweaks. But pretty much Baptist.

TL;DR: very antivaxx mother has forbidden me from getting the COVID shot, I need it in my career and also just genuinely want to get it. Is it a sin to disobey her and get it, especially if I hide it?

I'm 24, but living at home due to COVID and also because my mother would otherwise live alone. Dad is not in the picture and mom is VERY religious. I'm an only child and it's just us. We split the bills 50/50, but I pay rent for both of us. I have a bio degree and have interviewed for medical school, and I'll be getting results next month. I've also been accepted to a nursing program (fast track) in the meantime, and the point of this is I expect to be working in healthcare where the COVID vaccine will be mandatory. Right now, I just started a new job in a retirement home (all the residents are vaccinated and most of the staff), but it's only been a couple weeks. Regardless, I am now officially eligible. I was a frontline worker before, but not in healthcare. As for my mother, she's very, very much an antivaxxer / anti-mask. This is new since the pandemic started. She's always been big on conspiracy theories and the End Times, but never took issue with vaccines until now. I mean no disrespect, but she believes every single conspiracy theory. Illuminati, Gates, Obama being the antichrist, chemtrails, all of it. And now, this includes the COVID vaccine (all manufacturers) being the mark of the beast. Also something about Gates and Lady Gaga being behind it, microchips, secret birth control chemicals, turning people into GMO's, and so on. She also says God has given her special instructions to tell the world about how the vaccine is the mark of the beast, among other messages.

This results in my main issue: my mom has directly and clearly forbidden me from getting the COVID vaccine, multiple times, sometimes weekly or daily, and refused to let me go until I acknowledged her request. I always said something like "I understand", but never directly agreed to the order. Now I worry that I'd be committing a serious sin by getting the vaccine.

To make things very clear, I do not agree with my mom at all. The reason I mentioned school is because I studied immunology and microbiology in my undergrad, and I know that most of what my mom's online friends are saying about the vaccine is just completely false. But my mom won't have any of it, so I don't try to change her mind anymore. I love her, but I cannot agree with her. I want the vaccine, I believe it is safe, and I do not think for a second that it's the mark of the beast or secretly a contraceptive or contains a microchip or somehow has the ability to change my DNA. (And, no, the vaccine does not have any retroviral activity - this is not HIV, the mRNA will not be inserted into my genome. And luciferase is not named after Satan, but it doesn't matter because there is no luciferase in the vaccine itself.) At the end of the day, I try not to talk about this too much with my mom because she thinks I was brainwashed by satanists and that my education was a sham... but also because I know she wasn't able to go to school because she grew up in poverty, and it's a sore spot for her. I don't want her to think I feel superior. I really, really don't. So as much as I try not to talk about it, I completely disagree with her and I would like to get the vaccine. Plus, I work with seniors now, and I'll be working in healthcare... I need the vaccine to follow my dreams. But the problem is that I've been specifically ordered to not get any COVID vaccination... and I think I might have been forbidden from getting any vaccine ever again.

My big issue is that, even though I know the order I've been given is wrong and unsafe, I'm worried that getting the vaccine will be a sin for me. Not because of the vaccine itself, but because I'd be willfully disobeying my mother. I am unmarried, and while I have an amazing boyfriend, it'll be a while until I'm ready to be married. My mom's entire identity is wound up in her being my mother and my supreme, perfect, absolute authority... I think because I'm the only thing she has control over in her life. But I still love her. She's been through so much hardship, and the hierarchy and structure gives her a sense of stability. Plus, I'm all she has. I love her so much, but she genuinely thinks I'll go to hell if I get the vaccine. But even if she never finds out, even if I move out first... now I'm guilty of not only lying by omission, but still disobeying a direct order from my authority. I've spent my entire life fighting to be perfect and good for her and for God, and I never stopped trying. But this will be the first time in my life that I have consciously and deliberately disobeyed her. I've never once rebelled against her, even though she insists that I have... but this time, I'm actually planning a real, premeditated act of rebellion.

There's a whole lot wrapped up in this, but at the end of the day: will it be a sin if I get the COVID shot when my mother told me "do not get the COVID shot" over and over? I hope God would understand and forgive me, because I never meant to dishonour my mother, and I do not intend to dishonour her by doing this. I hope He would understand that she's been misled, and I'm doing this to protect the people I care about. But even if she never finds out, it feels like I'm doing something wrong.
