After months of steady decline, the number of COVID-19 cases in the U.S. are once again on the rise. And positive COVID-19 tests are also trending up. This is especially true in areas with lower vaccination rates.

The good news is we have very effective vaccines. To date, the Pfizer and Moderna (messenger RNA or mRNA) vaccines have shown excellent protection against severe illness and hospitalization from the Delta variant.

But, while rates of people getting vaccinated against COVID-19 have ticked up slightly in the last couple of weeks, they’re nowhere near where they were in the spring. Ultimately the biggest risk from the Delta variant is to those who are unvaccinated. They have a much higher chance of being infected and these folks can also spread the virus very easily to vulnerable people, such as those with weakened immune systems or young children who can’t yet get the vaccine.
