Health messaging recommendations

In light of false claims that COVID-19 does not exist, messaging may explain that COVID-19 is a real illness that is responsible for millions of deaths worldwide. COVID-19 is caused by the virus SARS-CoV-2, which was first identified in January 2020. Additional messaging may emphasize that all approved COVID-19 vaccines are safe. This includes mRNA COVID-19 vaccines, which have been monitored for over four years with no widespread safety concerns. Health care providers and public health communicators may continue to reiterate that staying up to date on COVID-19 vaccines prevents severe illness, hospitalization, long-term health complications, and death from COVID-19.
