Vaccination remains the best protection against COVID-19 infection. While highly effective, like most vaccines, they are not 100% perfect. However, if a vaccinated person does get sick or have a breakthrough infection, they are much less likely to be hospitalized or die than people who are not vaccinated.
“When we look at the overall severe infection, breakthrough infections are extremely uncommon,” says Dr. Abinash Virk, a Mayo Clinic infectious diseases physician. “When we look at mild or asymptomatic infections, they are a little bit more common. But when you take the big scheme of things and look at the number of vaccinated individuals that are positive compared to the unvaccinated individuals, it’s still substantially smaller than the unvaccinated.”
