US President-elect Joe Biden’s administration will deliver every dose of COVID-19 vaccine in the country to make sure people receive their booster shots on time, news agency AFP reported quoting a CNN report on Friday.

“The President-elect believes we must accelerate the distribution of the vaccine while continuing to ensure the Americans who need it most get it as soon as possible,” TJ Ducklo, a spokesman for Biden’s transition, told CNN.

“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,” Ducklo said.

The two vaccines developed by Moderna and Pfizer/BioNTech, the shots of which are being given to the healthcare workers, require the beneficiaries to receive booster shots in three to four weeks.

By eliminating the requirement to hold back half the supply in reserve, officials hope to scale up the number of people who can be reached quickly.

The news comes as vaccine rollout falters badly across the US, which has seen more than 365,000 COVID-19 deaths until now.

But the major bottleneck right now lies in the distribution, rather than supply: the federal government has overseen the shipping of 21.4 million first doses, of which only about 5.9 million have been administered.

The remaining roughly 15.5 million doses are not being held back as boosters, but are instead being held in cold storage at hospitals and clinics that have not yet used them.
