F.D.A. Agrees Moderna Can Increase Vaccine Supply in Each Vial

WASHINGTON – The Food and Drug Administration has informed drug maker Morden that it can put up to 40 percent more coronovirus vaccines in each of its vials, according to people familiar with the company’s operations, a simple and potential for stressed supply Fast way.

Although federal officials want Morden to present more data, showing that the switch won’t compromise vaccine quality, continued discussion is an indication that the nation’s vaccine stock may grow faster than expected, simply by the company Instead of 10 allowing loading up to 14 doses in each vial.

Modern currently supplies about half of the country’s vaccine stock. A 14-dose vial load can increase the country’s vaccine supply by up to 20 percent, when governors are struggling for more vaccines and more infectious variants of coronovirus are thought to spread quickly.

Two people familiar with the making of Modern, who spoke on condition of anonymity, said it would probably take less than 10 weeks to remodel the company’s production lines to accommodate the change, or from the end of April. Can be done first. This is because the volume of liquid in each vial will change, the vials themselves will remain the same size, so there will not be excessive changes in the production process. The statement on Friday said that the Modern Estimated Amendments could be made in two to three months.

Dr., who served as the scientific leader of the Trump administration’s vaccine development program. “It will be a big step,” said Monseff Saloi. “I think it will have an impact in the short term.”

Last month, Modern sought permission to increase the number of doses in its vials from the industry standard of 10 as 15. The time required for the final manufacturing phase will be cut when millions of small bottles are filled, capped and labeled, a prolonged bottleneck in injecting drug manufacturing.

The company is also asking regulators to approve changes at all stages to allow its vaccine to be stored and to allow more time to use the dose in a vial if the rubber pressure is punctured.

Dr. Saloi warns that Modern may still have to tighten up for its drug production, so it needed more vaccines to fill the vials. “Whether it will be an immediate 40 percent increase or a 20 percent increase for the first time is not clear,” he said. Another external expert said the FDA may require on-site inspection of the company’s manufacturing process if it changes.

In a recent email in response to questions asked about the company’s discussion with regulators, Modern’s chief executive, Stephen Bansell, wrote, “No comment.” Company spokesman Ray Jordan said negotiations with federal officials were ongoing. The front and back is expected with the FDA before the modern benefits final authorization for any changes.

On Thursday, President Biden announced that the federal government had locked in a total of 600 million doses of the vaccine from Modern and Pfizer, which developed its drug with a German partner, Biotech. Because two doses are required for each vaccine, there is also an interval of three to four weeks, which would be enough to cover 300 million Americans.

But receiving vaccine shipments quickly is a top priority. The Centers for Disease Control and Prevention has warned that by next month, a much more contagious form of the virus may be effective. Another variant that appears to undermine the preservation of existing vaccines has also been shown in the United States.

Mr. Biden said Thursday that the nation would not be able to vaccinate all Americans until the end of summer, citing “huge” logistical challenges. He blamed the Trump administration for not creating a better system to operate the shots. But as long as his time in office continues, the debate will become thinner.

So far, about 10 percent of Americans have received at least one dose of the vaccine. Pfizer has delivered about 52 percent of the nation’s supply, while Moderna has delivered 48 percent according to the CDC, while both companies are accelerating production, moving from modern to fuller vials if approved. is.

Pfizer is manufactured for six-dose vials, but Modern’s vials have enough free space to accommodate the additional dose. Nevertheless, there are limits to how much vaccine they can take.

Too much can cause cracks in a vial. Each vial should have enough room to ensure sufficient residue to extract the final dose.

The regulations now specify that once the puncture is complete, the entire vial of modern should be emptied within six hours, so fuller vials may have to be wasted more if the pharmacist over doses in that time frame. Struggle to evacuate.

The industry standard was set at 10 doses partly because the higher the risk of contamination the more often the vial’s rubber coating is perforated with a needle. But Dr. Saloi said those standards were not written for an epidemic that now claimed the lives of more than 475,000 Americans.

The exact number of doses that can be extracted per vial has become a highly frightening issue. Regulators allowed Pfizer to discard its vials in the form of six doses instead of five, so Pfizer is now credited with giving higher doses than before, although the amount has not changed. Six doses can be removed if health practitioners use specialized syringes, and federal and state officials say the device is now included in each shipment of the Pfizer vaccine.

Some health practitioners maintain that similar ambiguity exists with the product of modernism. While the vials are labeled for 10 doses, they are sometimes able to extract the 11th dose using special syringes.

A third manufacturer, Johnson & Johnson, has asked the FDA to approve its single-dose vaccine for emergency use, and a decision could be made by the end of this month. That company has promised to deliver another 100 million doses by the end of June, but federal officials say the company is still trying to ramp up its manufacturing.
