From someone who has had Covid I am 100% for natural immunity. Like many viruses, if the body is healthy and there are no underlying health issues, let it run its course. If you are overweight, a smoker or have health issues, you will get hit harder than the rest of us. Most if not all shots have some kind of side effects and do not garentte you not getting the virus. In my family, both people who got the shot and who did not - we ALL had VERY mild sytoms and it went away within a week.
