As therages on around the world, there's a light shining at the end of the tunnel. Vaccines for COVID-19 have been shown to be highly effective in protecting against serious illness and death, and will be key to getting out of this global crisis.
But in the US, the approval of vaccines from Pfizer-BioNTech and Moderna is only half the battle. Health officials still need to roll out these vaccines across the country, distributing doses through a patchwork of different state and local health systems and ensuring shots get into the arms of Americans as quickly as possible.
Marcus Plescia is the chief medical officer for the Association of State and Territorial Health Officials, the national organization representing more than 100,000 public health officials across the US, as well as the agencies they work for.
According to Plescia, getting the vaccine out to Americans is a huge task, involving nationwide logistics and aging public-health data systems. But though there are a number of factors getting in the way of a speedy rollout, he says there's one major issue that's hampered the early days of the vaccine program.
"The main bottleneck right now with the vaccine effort is the supply of the vaccine," Plescia told CNET.
"We knew there was going to be limited supply to begin with ... but I think a lot of people are losing track of the fact that we've only got 40 or 50 million doses right now, and we've already promised it to more people than that."
One of the main pain points for Americans at the moment is working out when and where they'll be able to get the vaccine. Part of that is down to the lack of available doses, but the scale of the rollout across 50 states has also caused problems.
According to Plescia, the federal government is responsible for buying the vaccine from suppliers and then distributing those doses to the states. The states then decide who gets vaccinated and in what order (largely based on guidelines provided by the US Centers for Disease Control and Prevention), before distributing doses to local health officials. Local health authorities also need to be able to send information back up the chain about who's getting vaccinated and where more doses are needed. But those public-health data systems that're used to share that information aren't as effective as they could be.
Add to that vaccines that require ultracold refrigeration and the need for two doses, and the rollout has been slower than originally hoped.
But there are some good signs too. The Biden administration has increased its orders from Pfizer and Moderna, bringing the total count up to 600 million, and new vaccine candidates could be approved in the US soon.
"I think by March, April, we should see significant changes," said Plescia. "First of all, there should be a lot more of the Pfizer and Moderna vaccines available for people. And then both AstraZeneca and Johnson & Johnson are on the verge of bringing their vaccines in front of the Food and Drug Administration for approval ... at that point, I think everybody will realize things are going to get better."
Plescia shared more insights on the COVID-19 vaccine rollout, including how states are allocating vaccines, and the best ways to find information on appointments. You can check out what he has to say in the video above.
