Governments around the world are picking up the pace at which they are approving and administering new vaccines in the fight against the coronavirus that has killed more than 2.5 million people and sickened more than 115 million worldwide.
Twelve vaccines are currently in use around the world, according to researchers at the London School of Hygiene and Tropical Medicine who are tracking the rollout. By their count, more than 263 million shots of the various vaccines had been administered globally as of March 1. Most are given as two jabs in the upper arm weeks apart.
