The Javits Center in New York City is now open 24 hours a day, seven days a week, after the approval of the Johnson & Johnson vaccine a week ago.
The convention center in Manhattan is accepting appointments around the clock in a sweeping effort to inoculate New Yorkers as quickly as possible. The effort began at 9 p.m. Friday, with the Johnson & Johnson vaccine only being distributed overnight, from 9 p.m. to 6 a.m.
Yankee Stadium in the Bronx and the New York State Fair grounds in Syracuse are other sites giving out vaccines around the clock, also using the Johnson & Johnson vaccine overnight.
More than 3.3 million New Yorkers have received at least one vaccine dose, according to state data. Over 1.7 million people, or 8.8% of the state, is fully vaccinated.
About 17% of the U.S. population is partially vaccinated and 8.6% is fully vaccinated, according to the Centers for Disease Control and Prevention. California has administered the most vaccines, followed by Texas, Florida, New York, Illinois and Pennsylvania, per the CDC.
Three different vaccines -- from Johnson & Johnson, Pfizer-BioNTech and Moderna -- are in use in the U.S.
In clinical trials, the Johnson & Johnson vaccine was 85% effective in preventing severe/critical illness and 66% effective in preventing symptomatic illness 28 days after vaccination. Importantly, it was 100% effective in preventing hospitalizations and death from COVID-19.
The Pfizer-BioNTech and Moderna vaccines are 95% and 94.1% effective in preventing symptomatic illness, respectively, but they were tested before the new, more contagious variants emerged. The Johnson & Johnson vaccine was tested against the new concerning variants and still performed well.
