The human immune system is designed to recognize foreign invaders (microbes, other substances), attack, kill, and then clear the debris away. For that reason, we must be sure that our bodies recognize our own cells as “protected” and the foreign ones as targets.
For the first time, mRNA (Pfizer, Moderna) and adenoviral DNA (Janssen) COVID-19 vaccines install the genetic code for our bodies to make a deadly foreign protein with the aspiration that our immune system would not only respond and protect us but also form live saving immunity from SARS-CoV-2.
