Delta is spreading but COVID vaccines 75-95% effective at preventing hospitalization

Scientists with the Centers for Disease Control and Prevention say that despite initial concerns about effectiveness of COVID-19 vaccines to prevent serious illness or hospitalization and the Delta Variant – Pfizer, Moderna, and Johnson & Johnson all offer solid protection. Taking that sentiment a step further CDC scientists say that COVID-19 vaccines remain effective at preventing hospitalization.

Since Delta began spreading around the U.S., existing COVID-19 vaccines have been effective against hospitalization in 75-95% of cases. “Vaccines remain effective in preventing hospitalization and severe disease but might be less effective in preventing infection or milder symptomatic illness,” officials said.

However, health officials are still warning residents across the U.S. that the greatest risk is among unvaccinated. “If we keep lingering without getting those people vaccinated that should be vaccinated, this thing could linger on, leading to the development of another variant, which could complicate things,” Dr. Anthony Fauci added following the report.

Booster shots have been recommended, but are rolling out more slowly than originally anticipated.
