New York Restarts J&J; World Hits 1 Billion Shots: Virus Update Bloomberg 52 mins ago (Bloomberg) -- New York will resume using the one-shot Johnson & Johnson vaccine at state-run sites “immediately,” Governor Andrew Cuomo said. Illinois, Maryland and Tennessee were among other states to begin giving the shot again, a day after U.S. health agencies lifted the pause on the vaccine while they reviewed serious and rare cases of blood clots. The first billion Covid-19 vaccine doses have been administered around the world. The U.K. has given half of its population a first dose of vaccine, a key milestone to reviving an economy among the worst-hit in the early months of the pandemic.
