The problem is that the Vaccines to do not offer permanent immunity. Immunity in most ends by 6 months. New research showed some who had imminunity for up to 8 months before they got re-infected. Every single person taking the vaccine today will at some point in time need the shot(s) again or booster shots.
No vaccine offers permanent immunity. Yellow fever is 10 years. Others less. I maintain an International Vaccine Certificate (Yellow Card) and have to be vaccinated periodically. Due to working in dodgy places I have been vaccinated against Yellow Fever, Measles, Rubella, Diphtheria, Meningitis, Hep A, B and C, Typhoid, Tetanus, Polio, Whooping Cough, Cholera and now Covid. Due to being born before 1980, I was vaccinated against Smallpox.
The flu vaccine has to be administered annually due to it being a fast mutating RNA virus.
