US President Joe Biden will announce within days the details of a plan to export 80 million coronavirus vaccine doses to other countries “without any political strings attached,” US State Secretary Antony Blinken said.

“In a few short days, in fact possibly as early as tomorrow, the president is going to announce in more detail the plan that he put together to push out 80 million vaccines around the world,” Blinken said at the US embassy in San Jose on his last day of a Latin American visit, AFP reports.

“We're going to do that in coordination with Covax [...] based on science and needs [...] without any political strings attached,” the top US diplomat said, referring to the global vaccine-sharing programme.
