Boosters, employer mandates drive increase in US vaccines

The number of Americans getting COVID-19 vaccines has steadily increased to a three-month high as seniors and people with medical conditions seek boosters, and government and employer mandates push more workers to take their first doses.

Demand is expected to spike in a few weeks if regulators authorize the Pfizer vaccine for elementary school children, and some states are reopening mass vaccination clinics in anticipation.

In Missouri, a mass vaccination site at a former Toys R Us store is set to open Monday. Virginia plans to roll out nine large vaccination centers over the next few weeks, including one at the Richmond International Raceway.
