The underlying long-lasting immunity assumption of herd immunity is flawed

In the debate over vaccine exemptions, one of the arguments commonly used in favor of increased vaccination is that of herd immunity. It’s necessary for the vast majority of a population to become vaccinated, officials say, for the betterment of the group, but there are flaws with this assumption.

Many people believe that once you receive a vaccine, you’re protected from that disease. This is a misconception. Vaccines do not confer the same kind of long-lasting immunity that is obtained from experiencing and recovering from the natural disease.

This is why booster shots are necessary, as vaccine-induced immunity eventually wanes. The vaccine simply cannot provide longer lasting immunity like that provided by a naturally acquired infection. So, what many people don’t realize is that there is such a thing as natural herd immunity. However, vaccines cannot provide this.

As an example, most Americans born before 1957 experienced measles and have stronger, more complete and longer lasting naturally acquired immunity, which allowed women to pass antibodies on to their babies to protect them from measles during the first year of life.

Things have definitely changed in the past 60 years. Because vaccine antibodies are different from naturally acquired measles antibodies, young vaccinated moms today cannot give longer-lasting naturally acquired measles antibodies to their newborns.
