Since the coronavirus started spreading across the globe in late 2019, scientists have been looking for a vaccine. Now that vaccines are proven, it will ultimately be up to each state to determine who will get the vaccine, and when?
"You know, clearly, if you can make a vaccine that you would only need to give a single dose of, that would represent a major step. From a practical point of view, it's so much easier to deploy a single-dose vaccine than it is to do it twice," says Stanford immunology researcher Bali Pulendran, Ph.D.
Especially considering volume. The federal government has reached agreements with major drug chains Walgreens and CVS to administer vaccines. Hospitals and clinics may handle a significant portion of the early load. And there have been discussions about public vaccination sites, similar to the drive up tents used for early virus testing.
