Novavax Covid-19 jab is 86% effective against Kent variant, new study suggests


The company behind the Novavax jab has announced that the vaccine is 86% effective against the Kent variant.

The news comes after a study enrolled more than 15,000 participants aged between 18 and 84, including 27% over the age of 65.

According to results from the phase three trial in the UK, the jab also offers 100% protection against severe disease, including all hospital admission and death.

Results show that it is 96% effective in preventing cases caused by the original strain of the coronavirus but 86% effective on combatting the Kent variant.

The UK has already ordered 60million doses of the vaccine, which will be manufactured at the Fujifilm plant in Stockton-on-Tees,

Stanley Erck, president and chief executive officer at Novavax, said: “We are very encouraged by the data showing that NVX-CoV2373 not only provided complete protection against the most severe forms of disease, but also dramatically reduced mild and moderate disease across both trials.

“Importantly, both studies confirmed efficacy against the variant strains.”

In participants 65 years of age and older, 10 cases of Covid-19 were observed, with 90% of those cases occurring in the placebo group.

Novavax expects to use the data to submit for regulatory approval across the world.

Under an in-principle agreement, the UK has secured 60 million doses of the Novavax vaccine.

The UK is providing infrastructure to Novavax in running a phase three clinical trial in the UK, and plans to manufacture its vaccine in the UK with Fujifilm Diosynth Biotechnologies.

In a smaller trial conducted in South Africa – where a more contagious variant is widely circulating, the Novavax vaccine was 55% effective, based on people without HIV but still fully prevented severe illness.
