The reason I ask is because our bodies as human beings have an amazing immune system and unless you have an autoimmune disease, naturally our bodies can heal ourselves from sickness.
I’m speaking primarily on the common cold, Influenza or anything similar like it, including even COVID.
I love natural immunity. That’s why I jump start it by introducing a weakened or dead version of the virus to my immune system, so I’m protected before I’m ever actually exposed.
You really trust big pharma?
