Russia accused of vaccine hacking as Brazil crosses 2 million cases

The US, UK and Canada have accused Russia of trying to steal coronavirus vaccine research as the pandemic surges across the world, with Brazil surpassing 2 million confirmed cases and the US notching a new daily record.

The virus has killed more than 588,000 people, infected more than 13.7 million and crippled the global economy since emerging late last year, and world hopes have turned to a vaccine to end the onslaught.
