    Professor Roger Seheult, MD gives an update on the vital question: how effective are current COVID vaccines against the Delta variant? 


    COVID Update 133: Vaccines Vs. Delta

    In our 133rd COVID-19 video update, Dr. Seheult discusses the latest CDC report on vaccines and the SARS-CoV-2 B.1.617.2 variant, commonly known as the Delta variant. In the report, the CDC tracks COVID-19 outcomes from nine different states and looks at numbers of hospitalizations, emergency room and urgent care visits, and positive COVID tests for those who were either fully vaccinated or unvaccinated. When breaking down this data for each of the vaccines available in the United States (Pfizer-BioNTech, Moderna, and Johnson & Johnson), the Moderna vaccine was the most effective at preventing hospitalizations (95%), followed by Pfizer (80%) and Johnson & Johnson (60%).
