With a green light from federal health officials, several US states have resumed use of the one-shot Johnson & Johnson coronavirus vaccine.
Among the other states ordering or recommending a resumption were Indiana, Arizona, Colorado, Louisiana, Michigan, Missouri, Nevada, New York, Tennessee and Virginia.
Those moves came swiftly after US health officials said Friday evening that they were lifting an 11-day pause on vaccinations using the J&J vaccine.
During the pause, scientific advisers decided the vaccine's benefits outweigh a rare risk of blood clot.
"The state of New York will resume administration of this vaccine at all of our state-run sites effective immediately," Governor Andrew Cuomo said in a statement on Saturday.
"The vaccine is the weapon that will win the war against COVID and allow everyone to resume normalcy, and we have three proven vaccines at our disposal.
"The sooner we all get vaccinated, the sooner we can put the long COVID nightmare behind us once and for all."
Among the venues where the J&J vaccine is being deployed is the Indianapolis Motor Speedway, where cars lined up on Saturday for free vaccinations for anyone 18 or older.
The US government uncovered 15 vaccine recipients who developed a highly unusual kind of blood clot out of nearly eight million people given the J&J shot.
All were women, most under age 50. Three died, and seven remain hospitalised.
But ultimately, federal health officials decided that J&J's one-and-done vaccine is critical to fight the pandemic - and that the small clot risk could be handled with warnings to help younger women decide if they should use that shot or an alternative.
