For two decades, scientists have been quietly developing self-spreading contagious vaccines. The National Institutes of Health funded this research, in which either DNA from a deadly pathogen is packaged in a contagious but less harmful virus, or the deadly virus’s lethality is weakened by engineering it in a lab. The resultant “vaccines” spread from one person to the next just like a contagious respiratory virus. Only 5 percent of regional populations would need to be immunized; the other 95 percent would “catch” the vaccine as it spreads person-to-person through community transmission.
