Canada still mum on vaccine-sharing details as G7 summit kicks off in U.K.

Prime Minister Justin Trudeau is the only leader at the G7 summit who has yet to pledge how many COVID-19 vaccine doses Canada will donate to poorer countries.

The United Kingdom says leaders are expected to agree to give other parts of the world access to one billion doses of COVID-19 vaccines through donations and funding.

The day before the summit, the U.K. promised to send at least 100 million doses within the next year, and United States President Joe Biden pledged he would send away another half a billion.

Trudeau is set to meet with British Prime Minister Boris Johnson.

Johnson has stated he wants the three-day gathering to produce promises on ways to end the pandemic by the end of next year.

Although Canada has yet to spell out its plans for donating vaccines, it has promised $440 million will go to COVAX, a vaccine-sharing initiative to buy doses directly from  manufacturers and give them to lower- and middle-income nations.

The G7 is gathering in Carbis Bay, an oceanside village in southwest England.
