“...the level of antibodies present in your body has you every bit as safe from reinfection as those who’ve been vaccinated.”

The COVID-19 vaccines available in the United States have all gone through full Phase 1, Phase 2, and Phase 3 clinical trials. The first recipients from the Phase 1 trials got their first doses back on March 16, 2020, over a year ago. They’re doing just fine and still immune from COVID-19.
