Pfizer: Covid-19 vaccine can be stored for two weeks at freezer temperatures



CNBC’s Meg Tirrell reports on the current state of Covid vaccines, including Pfizer’s remarks on its vaccine storage requirements. For access to live and exclusive video from CNBC subscribe to CNBC PRO:

Pfizer said Friday it is seeking permission from the Food and Drug Administration to store its Covid-19 vaccine for two weeks at temperatures commonly found in pharmaceutical freezers and refrigerators.

The vaccine, which was developed with German drugmaker BioNTech, currently needs to be stored in ultra-cold freezers that keep it between minus 112 and minus 76 degrees Fahrenheit, according to the FDA. Pfizer said it submitted new data to the U.S. agency that shows the vaccine is stable between minus 13 and 5 degrees Fahrenheit.

If the FDA grants the request, it could simplify logistics for distribution of the vaccine. Federal and state officials are trying to pick up the pace of vaccinations across the nation as the virus spreads.

“We have been continuously performing stability studies to support the production of the vaccine at commercial scale, with the goal of making the vaccine as accessible as possible for healthcare providers and people across the U.S. and around the world,” Pfizer CEO Albert Bourla said in a release. “If approved, this new storage option would offer pharmacies and vaccination centers greater flexibility in how they manage their vaccine supply.”

Medical experts had warned that Pfizer’s vaccine would present logistical challenges because of the need for ultracold temperatures. In December, U.S. officials said they quarantined several thousand doses in California and Alabama after an “anomaly” in the transportation process caused the storage temperature to get too cold.

The vaccine is shipped in a special thermal container that can be used as temporary storage for up to 30 days by refilling with dry ice every five days. Before mixing with a saline diluent, the vaccine may also be refrigerated for up to five days at standard refrigerator temperature, between 36 degrees and 46 degrees Fahrenheit, according to the company.

By comparison, Moderna’s vaccine needs to be shipped at between minus 13 and 5 degrees Fahrenheit. It 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 six months at minus 4 degrees Fahrenheit.

Johnson & Johnson’s vaccine, which is expected to be authorized for emergency use by the FDA as early as this month, has said it plans to ship its vaccine at 36 to 46 degrees Fahrenheit.

As additional stability data is obtained, Pfizer said it anticipates the shelf life could be extended, and alternate short-term temperature storage may be considered.

  1. I am the father son and

  2. HI We are a manufacturer of ultra-low temperature refrigerators. We do ultra-low temperature medical refrigeratorsdegrees Celsius

  3. 🛑MAYBE THIS IS WHY THE VACCINE'S ARE FAILING EFFICACY, LACK OF PROPER REFRIGERATION ?????

  4. This is why they pushing this vaccine…they need to use all the vaccine before it expires

  5. Who cares? Pfizzer guys are now filthy rich, forever.

  6. Which doesn’t explain the insanely slow rollout. For whatever reason vaccines are being slow rolled. I’m NOT pro vaccine I am pro what is obvious. They’ve have millions of doses across the US and they’re not being administered. Anyone who wants it should be able to get it and they can’t. Except in FL. They’re kicking ass for whatever reason. Again NOT pro vaccine just observing.

    I understand Pfizer shareholders made half a billion selling their shares

    Open Letter To The 45th President Of The United States Of America Donald J Trump

    THE GREATEST PRESIDENT OF ALL TIME

    God Bless You Donald Trump and give you the courage, strength and wisdom, to be on the right side of destiny, to be the greatest president the USA has ever had!!
    Sir you have achieved more in your 1st term in office than all the previous presidents combined.
    Once people realise and really wake up, and see your hand in the down fall of the cabal, the global elites, the corrupt bankers, mainstream media,politicians, the various royal families in the world and their insatiable thirst for adrenochrome and other nefarious activities.
    To gain the fountain of youth they have needlessly enslaved young children and trafficked them like disposable goods. All In the pursuit of their own insatiable greed & vanity, they have sacrificed their humanity and are pure evil and satanic to the core.
    Once people realise your great military war against the deep state, and all the 5 million children that you have rescued from dumbs (deep underground military bases). You will become a national & international hero.
    Posterity will confirm and history will record. That You Sir, will be remembered as the Greatest President of The USA. Who has actually given the power back to the people, aswell as their liberty & freedoms. May the sun always shine, on the glorious New Republic, that you have newly created, once the US goes back to constitutional law and away from corrupt marine law.
    Most importantly though Sir you will be remembered as the greatest peace maker and humanitarian.
    I can only reiterate that Donald you are an amazing man and inspirational in your vision. I can only wish you a very long live, aswell as your incredible family.
    God bless the USA and the rest of the world.
    MAGA!!

    REAL REASON FOR PLANDEMIC LOCKDOWN ARE RESCUING CHILDREN FROM (DUMBS) DEEP UNDERGROUND MILITARY BASES, GLOBAL FINANCIAL RESET & COVER UP OF BIGGEST US ELECTION FRAUD BY JOE BIDEN.
