Thousands of J&J vaccine doses nearing expiration
Slow demand, shaky confidence are factors
Slowing demand and the lingering effects of a 11-day pause on the Johnson & Johnson COVID-19 vaccine mean states have hundreds of thousands of doses that may expire before they can find willing arms.
“When we had more demand than the supply could meet, expiration dates weren’t a problem. Vaccine was being used up as fast as it came in the door,” said Dr. Kelly Moore, deputy director of the Immunization Action Coalition. That has changed in the past month. As of Wednesday, in Arkansas there were 93,271 doses of unadministered J&J vaccine. Of those, 42,971 expire on June 23 and another 10,042 expire on July 4, the Arkansas Department of Health said.
In Ohio, the governor has warned 200,000 J&J doses will have to be tossed on June 24 if they don’t get takers.
In Arizona, as many as 100,000 doses with the June 23 expiration date haven’t yet found people to use them. Other states have reported soon-to-expire doses as well.
“You’ve got three choices,” said John Grabenstein, a former Merck executive and former director of US Department of Defense military immunization program. “You increase demand and use the doses up, you extend the expiration date, or you throw them away.”
Increasing demand has proven difficult. Almost 52% of people in the United States have received at least one COVID-19 shot, but vaccination rates are falling to new lows.
Twelve states have seen vaccinations sink to 15 daily shots per 10,000 residents; Alabama had just four people per 10,000 residents get vaccinated last week,
On top of that, confidence in the J&J vaccine plummeted after the Food and Drug Administration and the Centers for Disease Control and Prevention paused the administration of the vaccine on April 13, when a small number of cases of a rare blood-clotting disorder were associated with the shot.
The pause was lifted after 11 days when an investigation showed that out of nearly 8 million who received the vaccine, only 15 people had developed the condition, and three had died.
Despite that, demand for the J&J
shot is lower than for the Pfizer/BioNTech or Moderna vaccines.
The vaccine was authorized on Feb. 27, and production ramped up in April. Unfortunately, That came just as the pause was initiated, leading to increasing supplies even as demand tanked.
Vaccine produced in April will begin to expire in June, which is why so many doses are now reaching the end of their shelf life.
CDC data this week shows about 10 million doses of J&J vaccine has never been administered, about half of the doses delivered. When those doses might reach their expiration dates isn’t known.
Extending the shelf life requires extensive testing and FDA approval.
As they’re manufactured, vials of vaccine are put aside for stability testing to determine how long they stay potent, Grabenstein said.
“Every month you test five or 10 vials and see how they do,” he said. The numbers are reported to the FDA, which can extend the shelf life if warranted.
“A vaccine approved 10 years ago might have started with a 12-month stability at first and then, over time, testing might extend that two years.”
When J&J first presented its data to the FDA’s Vaccines and Related Biological Products Advisory Committee on Feb. 26, the vaccine had a shelf life of three months when refrigerated at 36 to 46 degrees. It remained stable for two years when frozen at minus 4 degrees.
As more data is gathered, the company and the FDA are looking at whether
the date can be extended. Each vial of vaccine is shipped with a code that can be entered into a website, which will tell when the vial expires.
Even expired, the J&J doses aren’t necessarily ineffective, Moore said. But without data, they can’t be used. “You’re not allowed to guess about expiration dates,” she said.
Any vaccine that isn’t used by its expiration date must be disposed of properly, which means a process of “controlled destruction” such as incineration.
“You don’t want this stuff to get diverted so that substandard or counterfeit vaccine could be sold to unsuspecting people,” Grabenstein said.
Some public health officials are holding out hope more creative answers can be found in the two weeks that remain for some of the doses.
William Humble, executive director of the Arizona Public Health Association, hopes Arizona can find a way to get its unused vaccine to people in Mexico just across the border, where the J&J vaccine is authorized but little is available.
The Arizona Department of Health Services does have vaccination options near the border that don’t require proof of citizenship, and the state participates in the federal vaccine pool, which is where vaccines to be donated internationally will come from, said spokesman Steve Elliott. Humble hopes for a big push to make sure every last dose is used before it must be destroyed.
