U.S. Health Officials Eye COVID-19 Booster Shots As Variant Spreads

U.S. health officials are exploring COVID-19 booster shot options as Delta variant spreads.

 "300 million shots in arms in under 150 days. That's an important milestone," President Joe Biden said. As increasing numbers of Americans are vaccinated for COVID-19, health officials are exploring whether they will need booster shots in future. "So, we want to be ahead of this booster question. We're making plans now, should we need them soon," said Dr. Rochelle Walensky, Director of the Centers for Disease Control. "But we're actually actively looking at the science. This will be a topic of next week's advisory committee, to the immunization practices panel next week at CDC."
