On November 17, U.S. Sentator Rand Paul of Kentucky compared the effectiveness of the Moderna and Pfizer vaccines with "naturally acquired COVID-19" on Twitter. He folllowed-up by asking, "Why does the left accept immune theory when it comes to vaccines, but not when discussing naturally acquired immunity?" Besides ignoring the point of vaccines, which is to protect the public BEFORE they get sick, the comparison of natural COVID-19 infection and vaccine efficacy is inaccurate. Reinfections have not been confirmed and the efficacy of naturally-acquired immunity is still not understood. A person has to survive or suffer through the infection to get protection from naturally acquiring COVID-19. The Centers for Disease Control and Prevention advises all people, including those who have recovered from COVID-19, to continue to physically distance, wear masks, wash their hands and avoid crowds.
