U.S. firm Johnson & Johnson is likely to apply for EU approval for the company’s Covid-19 vaccine candidate in February, a top lawmaker said.

EU countries could begin rolling out Moderna’s Covid-19 vaccine as soon as next week after authorities approved the region’s second shot on Jan. 6, with more infectious variants of the virus adding extra urgency to inoculation efforts.

The European Union was asked to allow an extra dose of the Covid-19 vaccine developed by Pfizer and BioNTech to be taken from each vial, a practice allowed elsewhere that would make scarce supplies go further.

Europe launched a mass Covid-19 vaccination drive on Dec. 27 with pensioners and medics lining up to get the first shots to see off a pandemic that has crippled economies and claimed more than 1.7 million lives worldwide.
