Washington, Jan 12 (TIWN) US President-elect Joe Biden has recently announced a controversial shift in Covid-19 vaccination strategy, aiming to release all available doses as soon as possible.

According to a CNN report, it could also be a risky strategy as both Pfizer/BioNTech and Moderna's vaccines require two doses, administered at specific intervals and vaccine manufacturing has not ramped up as rapidly as many experts had hoped.

"The President-elect believes we must accelerate distribution of the vaccine while continuing to ensure the Americans who need it most get it as soon as possible. He supports releasing available doses immediately, and believes the government should stop holding back vaccine supply so we can get more shots in Americans' arms now," TJ Ducklo, a spokesman for Biden's transition team, told CNN in an exclusive interview.

"He will share additional details next week on how his administration will begin releasing available doses when he assumes office on January 20," Ducklo added.
