If you can get the vaccines definitely do it. I've got my first shot and so have much of my close family.
If we want to throw around personal acedotes, my 88-year-old great aunt got COVID and was fine. A friend in his 60's got it and died. My uncle got it and was fine. Another friend in his 50's got it back in Feb 2020 and he's still suffering from long COVID. A friend who is a ICU nurse had several coworkers die from it, including a young, healthy doctor. This is a very unpredictable virus and part of the problem is that so many people can get it and be fine so it keeps spreading.
I grew up around hippy anti-vaxxers and alt medicine believers so I'm familiar with all the fears over big pharma and the evils of mainstream medicine and instead putting faith in supplements and natural cures gurus. Thankfully my grandparents were both doctors and my grandmother worked in public health so my mom made sure I got all my shots as a kid.
"Mainstream" medicine is looking at Vitamin D in relation to COVID but the data isn't very strong yet in either direction but it's not going to stop the current spread:

Vitamins and "building a healthy immune system" are fine but these vaccines are even better.
If you can only get the J&J shot and you're worried it isn't as good, check out this video - in short all the vaccines are equally effective in preventing hospitalization and deaths which is what really matters:
The vaccines don't change your DNA and it's not gene therapy. It provokes an immune reaction to a specific protein that the virus needs in order to infect a cell. The science behind this is actually really cool. I'm excited for future mRNA vaccines because they open a lot of new avenues for vaccine development.
Looking at the 99.7% survivability rate and saying "I'll take those odds" is a shortsighted view. Let's say the case-mortality rate is 0.3% like people keep posting (I find a number more like 1.5% elsewhere but whatever). So that's 3 people dying out of every 1000 people who get it. Given how a virus can spread exponentially, that quickly becomes millions of (now preventable) deaths, even if you're lucky enough to not be one of them.

Before you say "but what about heart attacks, what about flu deaths, what about car crashes...", we already do a ton to prevent those deaths too: annual flu vaccines, car safety standards, etc. But COVID is a new (and now preventable!) cause of death and it's already in the top 3 causes of death in the US:

The jury is still out on if being vaccinated prevents you from spreading it but research to answer that is under way:

What I've seen doctors and scientists predict is that viral load should be lower so you'd expect the risks of spreading a serious infection to be lower too.
Bill Gates didn't say he wants to kill billions of people with a vaccine. He has talked about reducing mortality rates with vaccines while also giving more people access to birth control so they can choose when to have kids. That's what "reduce population GROWTH" means, not killing a bunch of people because he's a James Bond villain lol:
