It’s been a grim week in the course of the global coronavirus pandemic, with spread of the virus spiraling out of control in India, even as vaccination efforts progress around the globe.
On the vaccine front, there have been some brighter spots: Regulators in both the U.S. and EU have resumed the rollout of Johnson & Johnson’s COVID shot, an important show of confidence for one of the vaccines most practical and vital to speedily addressing global need. And in the U.S., there comes another strong proof of concept for shots already widely in use: The Centers for Disease Control and Prevention today published a study that found the Pfizer-BioNTech and Moderna vaccines were 94% effective against COVID-19 hospitalization among fully-vaccinated adults over the age of 65.
That news comes of course at a pivotal moment in America’s vaccine drive, where in many places, demand for COVID shots no longer outstrips supply, despite community vaccination rates still falling far short of those required to reach herd immunity. As a result, public health leaders and employers are turning to out-of-the-box strategies to promote vaccination.
As of April 28, 142.7 million Americans—including 82% of seniors, 55% of adults, and 43% of the total population—had received at least one dose of a COVID vaccine, according to data from the CDC. That’s up from 133.4 million people a week ago. More Americans received a second vaccine dose than a first in the past seven days. The number of fully vaccinated Americans now stands at 98 million: 38% of adults and just under 30% of the total population.
In total, the country has administered 234.6 million of the 301.9 million vaccine doses distributed across the country. All but 8.1 million of those have been doses of the mRNA Pfizer and Moderna vaccines.
Across the country, the picture is increasingly varied. In New Hampshire, the highest-ranking state, almost 60% of the population has received at least one COVID shot; in Mississippi, the lowest-ranking state, only 30.7% of residents have received a shot (compared to 29.7% one week ago). Half of U.S. states have reached at least 40% of their population having received a COVID vaccine.
