Follow the Science – Except When it comes to Natural Immunity
By Brian C.Joondeph, MD
Viruses and other infectious organisms have been around since long before humans walked the planet. While many microorganisms are helpful and necessary for human survival and function, others bring disease and death. Immunity is what prevents humans from being wiped out by a particularly virulent bug.
The CDC defines immunity as “protection from an infectious disease. If you are immune to a disease, you can be exposed to it without becoming infected.”
How does one achieve immunity? As the CDC explains, there are two ways.
Natural immunity is acquired from exposure to the disease organism through infection with the actual disease.
Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.
Vaccines have not been around forever, the first one being the smallpox vaccine invented in 1796. Since then, we have had many other vaccines including measles, mumps, hepatitis, and shingles. Yet we haven’t had efficacious vaccines for respiratory viruses, with the flu vaccine providing only about 50 percent effectiveness, depending on the season.
