The Federal Aviation Administration said it supported the “first mass air shipment” of Covid-19 vaccines, as pharmaceutical companies and airlines prepare networks for broad distribution.
Ahead of the approvals, pharmaceutical companies, airlines and other parts of the supply chain are preparing for distribution once regulators give a green light, a vast network that will include cold storage to preserve the vaccines.
The Food and Drug Administration hasn’t yet approved a Covid-19 vaccine. Pfizer, which developed its vaccine with BioNTech, and Moderna both said recent trials show their vaccines are each more than 90% effective in preventing Covid-19 infection.
Pfizer didn’t respond to multiple requests for comment. Spokeswoman Kim Bencker has previously said the company won’t ship the vaccine until it wins approval from the FDA for emergency use. Pfizer submitted its application for emergency clearance on Nov. 20, and the FDA is expected to publicly discuss it when the agency’s Vaccines and Related Biological Products Advisory Committee next meets Dec. 10. Moderna said it plans to submit its application Monday.
Some Americans could get their first dose of the vaccine in a few weeks if regulators sign off on either vaccine without delay.
Pfizer’s vaccine requires a storage temperature of minus 94 degrees Fahrenheit. By comparison, Moderna has said its vaccine remains stable at 36 to 46 degrees Fahrenheit, the temperature of a standard home or medical refrigerator, for up to 30 days. It can be stored for up to six months at negative 4 degrees Fahrenheit.
The United flight, first reported by The Wall Street Journal, required special approval from federal regulators to carry more dry ice than is normally allowed, the people said. Vaccines are stored at below-freezing temperatures.
The FAA last month created a special team to address “safe, expeditious, and efficient transportation of vaccines.”
“Several vaccines need continued cold temperatures during transport, which, in some circumstances, require dry ice, a hazardous material,” the FAA said in a statement. “The FAA is working with manufacturers, air carriers, and airport authorities to provide guidance on implementing current regulatory requirements for safely transporting large quantities of dry ice in air cargo.”
Pfizer’s vaccine will initially be very limited. It’s previously said it can make 50 million doses of its two-dose regimen by the end of the year — enough to immunize 25 million of the nation’s roughly 331 million people. The company plans to ship frozen vials of the vaccine to vaccination points from its sites in Kalamazoo, Michigan, and Puurs, Belgium.
Other airlines are also preparing for vaccine shipments.
American Airlines’ cargo department last week started trial flights with its pharmaceutical partners from Miami to South America “to stress test the thermal packaging and operational handling process we have created for shipping vaccines,” spokeswoman Stacy Day said in a statement.
One challenge ahead is that air cargo capacity has been limited because of the pandemic. Since airlines have canceled so many flights, there is less aircraft belly space available to transport goods. United and other airlines, however, have begun operating cargo-only flights to help make up for lost passenger revenue.
Airlines have used their critical role transporting potentially lifesaving vaccines as leverage in seeking additional federal aid while passenger traffic remains a fraction of last year’s levels. “As the nation looks forward and takes on the logistical challenges of distributing a vaccine, it will be important to ensure there are sufficient certified employees and planes in service necessary for adequate capacity to complete the task,” Airlines for America, a trade group that represents the largest U.S. airlines, said in a Nov. 18 letter to congressional leaders.
Some federal agencies have already started sending vaccination plans around to staff. Five agencies have begun telling employees they could receive Pfizer’s or Moderna’s Covid-19 vaccine in as little as eight weeks, a person with knowledge of those plans told CNBC on Nov. 20.
