Eight different Covid-19 vaccines are currently being used around the world and just over 172 million people have received their first dose, 2.2 for every 100 people. All of the vaccines being used require two shots but that is set to change with Johnson & Johnson’s JNJ+0.3%JNJ+0.3% one-shot vaccine expected to gain regulatory approval for use in the United States within weeks. As it stands, the first Covid-19 vaccine to be authorized for use in the U.S. is also the most widely used shot globally, according to information from website Our World in Data reported by The New York Times.
