Johnson & Johnson Vice Chairman of the Executive Committee and Chief Scientific Officer Paul Stoffels said in a statement that the results “with a single-shot COVID-19 vaccine candidate represent a promising moment. The potential to significantly reduce the burden of severe disease, by providing an effective and well-tolerated vaccine with just one immunization, is a critical component of the global public health response.”

The company, which announced its fourth-quarter and full-year 2020 results earlier this week and beat analysts’ expectations, saw its shares slide today following the announcement. The stock dropped 3.4% mid-morning.

“These are spectacular results, and we are very pleased to have helped Novavax with the development of this vaccine,” Clive Dix, chair, U.K. Vaccine Taskforce, said in a statement. “The efficacy shown against the emerging variants is also extremely encouraging. This is an incredible achievement that will ensure we can protect individuals in the UK and the rest of the world from this virus.”

Following the announcement, Novavax’s shares were up 56% mid-morning.
