French drugmaker Sanofi and Britain’s GlaxoSmithKline will supply 200 million doses of their Covid-19 candidate vaccine to a global inoculation scheme backed by the World Health Organization.

A vaccine against Covid-19 may be ready by year-end, the head of the World Health Organization (WHO) said, without elaborating.

Will the solitary path the United States is on, insulate it from further Covid-19 pandemic-related damage? Christopher Snyder, a professor of economics at Dartmouth University, believes the answer depends largely on the eventual vaccine’s level of efficacy.

The global death toll from Covid-19 could double to 2 million before a successful vaccine is widely used and could be even higher without concerted action to curb the pandemic, an official at the World Health Organization said.

More than 150 countries signed on to a World Health Organization (WHO) program to ensure global access to a Covid-19 vaccine, however, the United States, Russia and China refrained from signing the agreement.

Wealthier countries that join the World Health Organization’s Covid-19 vaccine plan are being offered a new option to pick and choose which shots they get while reserving a right to receive their “full share” of doses, documents seen by Reuters show.

Some 172 countries are engaging with the COVAX facility designed to ensure equitable access to Covid-19 vaccines, the World Health Organization said, but more funding is needed and countries need now to make binding commitments.
