Boosters, employer mandates drive increase in US vaccines

The total number of doses being administered in the US is climbing toward an average of 1 million per day, almost double the level from mid-July — but still far below last spring.

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.
