(AP) — Missouri vaccinators are expected to receive the first 50,000 doses of the newly-approved Johnson & Johnson COVID-19 vaccine by Wednesday, and the state’s health director says the shots can start as soon as the doses arrive. The Food and Drug Administration cleared the Johnson & Johnson vaccine on Saturday. Nearly 4 million doses of the one-shot vaccine are now being shipped across the U.S. Some states expect to begin injections Tuesday, but Missouri Department of Health and Senior Services spokeswoman Lisa Cox said Monday that the first doses in Missouri are expected a day later.
