A coronavirus vaccine, when available to the general public, may require two doses for each recipient instead of one and that could be problematic, experts say.
Supply chain issues that have hampered procurement of test kits and protective gear could also affect distribution of the vaccine nationally, CNN reported.
“You have to double everything in the supply chain,” said Nada Sanders, a professor of supply chain management at Northeastern University, CNN reported. “The syringes, can they double up? Can the vials double up? Can the stoppers double up? Can the needles double up? Everybody has to double up and then they all have to get it in time at the various entities along the supply chain.”
Getting people to come back for a second dose could also be an issue. Dr. Nelson Michael, director of the Center for Infectious Diseases Research at Walter Reed Army Institute of Research who works with Operation Warp Speed — the federal program aiming to deliver a vaccine within months — said he understands the conundrum.
“These are the sorts of things that I think we need to think about, to make sure that we can incentivize people to come back to make it easy as possible for them to adhere to a two-shot regimen,” Michael said, CNN reported.
As of Monday, the U.S. has more than 6 million reported coronavirus cases, including approximately 183,000 deaths, according to a Johns Hopkins University tracker.
