I can scarcely think of a worse thing that you could do to the immune system of a young person. Young people, particularly children under 5 NEED to be exposed to a wide variety of pathogens. The entire COVID panic has been exemplified by people doing and being encouraged, even forced, to do the exact opposite of what should be done. They are going to create a generation of people who will be increasingly susceptible to pathogens that they are naïve to and also susceptible to autoimmune diseases caused by a lack of proper training of their immune systems in early childhood. This maniacal focus on vaccines as some panacea to all problems and a phobia of natural infection is just insane. That supposedly learned people such as epidemiologists could dare to come out and recommend COVID or flu vaccines for children is criminal. I recently had a birthday party for my 4 year old. It's winter, so pretty much all 4 year olds are sick in some way. Encouragingly, pretty much all of the parents that I talked to there understood that children NEED to get sick in order to strengthen their immune systems. Normal people seem to be aware of this, but the politicians and technocrats will try to push their flawed sterility and "safety" theory.
