The US public and even some health experts may have underestimated the Covid-19 vaccine made by Janssen, a division of Johnson & Johnson, new data shows. And there's emerging evidence that it could still play an important role ahead.
A study published Thursday in the medical journal JAMA Network Open found that the J&J vaccine remains durable and effective, even through the surge of cases caused by the Delta variant. It was 76% effective overall in preventing Covid-19 infections and 81% effective in preventing Covid-related hospitalizations. The study also showed that it provided lasting immunity at least six months after the shots.
"In people who got the Pfizer vaccine initially and then a boosted with the J&J vaccine, those people made pretty high levels of neutralizing antibodies to Omicron: 10 times higher than people who got two shots with just the J&J vaccine," he said."So the J&J vaccine might be a good booster for people who got an mRNA vaccine initially.
