The co-founder of BioNTech said Tuesday it was "highly likely" that its vaccine against the coronavirus works against the mutated strain detected in Britain, but it could also adapt the vaccine if necessary in six weeks.

The first Covid-19 vaccines landed on Canadian soil on Sunday, Prime Minister Justin Trudeau said, and some Canadians are expected to roll up their sleeves for a shot as soon as Monday.

The US could soon be the next country to launch an immunization campaign against the novel coronavirus after experts voted to recommend emergency approval for Pfizer-BioNTech's vaccine

The World Health Organization said on Wednesday it had received data from Pfizer and BioNTech on the Covid-19 vaccine and was reviewing it for "possible listing for emergency use", a benchmark for countries to authorise national use.

Pfizer Inc and BioNTech's Covid-19 vaccine could be rolled out in Europe this month, the companies said on Tuesday after they applied for EU emergency approval for the shot.

Final results from Pfizer Inc's Covid-19 vaccine trial showed its shot had a 95% success rate and two months of safety data, paving the way for the drugmaker to apply for an emergency US authorization within days, it said on Wednesday.

Just as the novel coronavirus was gaining a foothold in the United States in mid-March, Pfizer Inc Chief Executive Albert Bourla called on his top vaccine scientists and laid out a clear mission:

Qatar would be able to get an initial quantity of the Covid-19 vaccine developed by Pfizer and BioNTech, if approved by regulators, by the end of this year or early in 2021, a senior health official has said.

BioNTech, first in the race to produce evidence of a working COVID-19 vaccine, is planning to price the two-shot regimen below "typical market rates" and would differentiate pricing between countries or regions.

German Health Minister Jens Spahn expects the European Commision to sign a purchase agreement with BioNTech and its partner Pfizer for its potential vaccine against Covid-19 "in the coming days."

Spain would get the first vaccines against Covid-19 developed by US pharmaceuticals Pfizer and its partner BioNTech in early 2021, Health Minister Salvador Illa said on Tuesday.

The Ministry of Public Health (MoPH) has decided to provide the Covid-19 vaccine free of charge to all Qatar residents, a top official said Monday.
