More than 9.3 million Americans have received their first shot of the vaccine, or less than 3% of the population, according to the Centers for Disease Control and Prevention. That is well short of the hundreds of millions who experts say will need to be inoculated to vanquish the outbreak.
The effort is ramping up around the country. Large-scale, drive-thru vaccination sites have opened at stadiums and other places, enabling people to get their shots through their car windows.
Also, an increasing number of states have begun offering vaccinations to the next group in line — senior citizens — with the minimum age varying from place to place at 65, 70 or 75. Up to now, health care workers and nursing home residents have been given priority in most places.
The Trump administration announced plans Tuesday to speed up the vaccination drive by releasing the whole supply of doses, instead of holding large quantities in reserve to make sure people get their second shot on time.
