Are Booster Doses of Pfizer's and Moderna's COVID Vaccines on the Way?
Israel has begun giving a third dose of the COVID-19 vaccine developed by Pfizer (NYSE: PFE) and BioNTech (NASDAQ: BNTX) to some adults. The decision was made after COVID-19 cases began to surge in the country due to the spread of the delta variant.
The delta variant isn't just affecting Israel, though. It's now the most prevalent coronavirus strain in the U.S., causing 58% of all COVID-19 cases.
While Israel bought large quantities of the Pfizer-BioNTech vaccine, the U.S. has purchased hundreds of millions of doses of several COVID-19 vaccines. The two most widely given vaccines in the U.S. are those sold by Pfizer and Moderna (NASDAQ: MRNA).
