Johnson & Johnson is working on several next-generation versions of its Covid-19 vaccine that may be needed to bolster protection against some of the coronavirus variants that have emerged.
J&J Chief Executive Alex Gorsky said Thursday he was hopeful J&J’s newly authorized vaccine and other current Covid-19 shots provide some protection against new variants, but booster shots or modified versions of original vaccines might be needed. “We have to be prepared,” Mr. Gorsky said Thursday. “We should prepare for the worst and hope for the best.”
J&J’s original Covid-19 vaccine was authorized by U.S. regulators in late February. In a late-stage trial,at protecting people in a large international study from moderate to severe Covid-19 disease. But its efficacy was lower in the South Africa portion of the trial, where a variant has spread that has shown resistance to vaccines that were designed to work primarily against an earlier version of the virus that circulated widely last year.
