European Union's drug regulator on Monday approved use of the Covid-19 vaccine from US-based Novavax in people 18 years and older, paving the way for a fifth coronavirus shot in the region as the Omicron coronavirus variant spreads.
Data from two large studies showed the vaccine has an efficacy of around 90 per cent, the European Medicines Agency (EMA) said, adding that there was currently limited data on its efficacy against some variants of concern, including Omicron.
"After a thorough evaluation, EMA's human medicines committee (CHMP) concluded by consensus that the data on the vaccine were robust and met the EU criteria for efficacy, safety and quality," the regulator said.
Covid-19 infections have broken records in parts of Europe in recent weeks, with governments and researchers scrambling to bolster defences against the fast-spreading Omicron coronavirus variant, prompting renewed curbs ahead of the holidays.
The endorsement for the two-dose vaccine, branded Nuvaxovid, comes well ahead of possible authorisation in the United States, where Novavax has had to resolve manufacturing issues and expects to file for approval by the end of the year.
The regulatory process in the EU has taken longer than expected too. The European Medicines Agency started a rolling review of the data in February.
Novavax and the EU reached a preliminary deal in December 2020 for the supply of the vaccine, but due to regulatory and production issues the final contract for up to 200 million doses was only signed in August.
The company said on Monday it would start shipping vaccines to the EU's 27 member states in January.
The shot received its first regulatory greenlight in Indonesia last month and is awaiting approval in Japan, where it would be manufactured and distributed by Takeda Pharmaceutical .
