President Biden himself is teaching us an important lesson about COVID-19. Despite being fully vaccinated and receiving two booster shots, President Biden has again tested positive for COVID-19. He is doing well, but this fact shows that COVID can easily return.
In the future, it seems like COVID-19 may become a seasonal illness. We will have to get vaccinated against it every season and may contract it once or twice a year.
But this theoretical situation only applies to those who follow the science. Now, more than ever, we must get vaccinated and boostered. Otherwise, the virus will remain deadly.
