Herd immunity is not junk science or a false theory. Herd immunity is real, it works, and explains how people in a community are protected from a disease when vaccination rates are above a certain threshold.
There are several vaccines that can help protect kids from getting bacterial meningitis.
The Hib vaccine protects against H. influenzae type b (Hib), an invasive bacteria that causes epiglottitis, meningitis, pneumonia, septic arthritis, and cellulitis.
Why didn’t everyone die in the pre-vaccine era when we had fewer vaccines and vaccination rates were below herd immunity levels?
