Johnson & Johnson asks FDA to authorize booster shots

Drug maker Johnson & Johnson on Tuesday asked the US Food and Drug Administration (FDA) to authorize booster shots of its COVID-19 vaccine for people over the age of 18.

"Our clinical program has found that a booster of our COVID-19 vaccine increases levels of protection for those who have received our single-shot vaccine to 94 percent," said Mathai Mammen, global head of research and development at J&J, as quoted by the AFP news agency.
