COVID-19 vaccine booster shots will be made widely available to Americans starting on Sept. 20, U.S. health officials said on Wednesday, citing data showing diminishing protection from the initial vaccinations as infections rise from the Delta variant.
U.S. officials will offer a third shot to Americans who received their initial inoculation of two-dose COVID-19 vaccines made by Moderna Inc and by Pfizer Inc and BioNTech AG at least eight months earlier, the Department of Health and Human Services said in a statement.
