People don't seem to be addressing the main point of this thread. It is that there are not just two positions - vaccination or vaccination opposition. Measles, mumps and other diseases are referenced, but nobody points out that medical opinion states that vaccination is not required if a person has recovered from a prior infection. It admits that natural immunity is as good, or better, than vaccination. Covid is the first disease that is being promoted by governments in contradiction of this fact. I genuinely believe that I have strong natural immunity, and because of my lifestyle and age, I cannot afford to risk vaccination which research indicates that it will reduce my immunity, and will expose me to short and long term health risks. I'm not anti-vax, but I believe that vaccines should be tested comprehensively, and the result made available for public scrutiny. Also, I believe that adequate should be given to those administering them. For example, many of the vaccination failures may be the result of a failure to aspirate the syringe before pressing the plunger.
in short: you afraid of the injection.
No, doctors don't say it will lower your immunity. Maybe some weird blog becarefulpatriots.com says that.
WHO recommends that everyone get vaccinated. They're scientists, science works with consensus, based on studies. You don't choose to believe the doctor you like the most. This is opinion, not science.
There may be contraindications for a few people, very few. But basically those who refuse to be vaccinated harm the collective; selfish people who just don't care and put their fears above everyone else, sadly.
