The reason herd immunity can’t happen in a vaccinated (artificial immune) population
1. Vaccines are not 100% effective (sometimes as low as 50%)
2. Vaccines create temporal (short-term) antibodies ONLY, most of these vaccines lost their effectiveness 2 to 10 years after being given.
3. Dr. Merrill Chase , did clear-cut research on this issue back in the 1950s. His results are clear: antibody levels don’t determine immunity.
In essence, at least 50% or more of the population was unprotected for decades.
