J&J developing several next-generation COVID-19 vaccines, says CEO

Johnson & Johnson is developing several next generation COVID-19 vaccines against the emerging variants of the coronavirus, Chief Executive Officer Alex Gorsky said on Thursday. The drugmaker, which won the U.S. emergency use authorization of a one-shot vaccine last month, had previously said it was developing a second-generation vaccine that would target the variant first identified in South Africa. J&J is also working on a two-dose version of its vaccine.
