J&J Says Vaccine Will Work Against Delta Variant; WHO urges Western nations to accept travelers with Chinese vaccines

Concern about the highly transmissible delta COVID-19 variant and its spread among the unvaccinated continues to grow as U.S. cases rise, but positive news about vaccines’ ability to fight the virus keeps coming.

Thursday, Johnson & Johnson said its one-dose shot protects against the delta variant, citing lab tests of vaccine recipients’ blood. And amid concerns their shot might require a booster, the company said its immune response lasts eight months and counting.

Public health experts say the variant poses the most danger in regions where vaccinations are sparse. 

The variants “are able to find any gaps in our protection,” Dr. Hilary Babcock of Washington University at St. Louis said, pointing to how hospital beds and intensive care units in Missouri’s least-vaccinated southwestern counties suddenly are filling — mostly with adults under 40 who never received the shots.

“Any suffering or death from COVID-19 is tragic,” Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, said Thursday in urging more Americans to roll up their sleeves ahead of the delta variant’s spread. “With vaccines available across the country, the suffering and loss we are now seeing is nearly entirely avoidable.”
