Sorry, not buying it. Flu vaccines are not mRNA but we still have to get a shot every year. I don't believe there has ever been herd immunity to the flu virus.The mRNA vaccines have proven how badly they do not work over the last 16 months because those vaccinated are still getting infected and spreading the virus even more than those not vaccinated. The only advantages of the vaccine are very temporary. Good for less than 6 months. So are even worse than no vaccine at al, because they again prevent herd immunity by causing a 6 month delay.
