Manufacturing and Distributing the COVID-19 Vaccine

Pfizer consistently and diligently monitors the supply of our medicines. We operate one of the most sophisticated supply chain systems in the industry, with over 35 Pfizer-owned sites and over 300 suppliers globally, which provides capacity and redundancy as needed. Our manufacturing and supply chain professionals have been working non-stop to ensure that the global supply of Pfizer medicines continue to be available to patients. We have implemented an unprecedented and comprehensive preparedness plan to control our site operations and will continue to provide timely updates if there is any new information to be shared.

A Look at Cold Storage & Distribution

with Mike McDermott, President, Pfizer Global Supply 
 

  • Where is the Pfizer-BioNTech COVID-19 vaccine made?

    Pfizer and BioNTech are continuing to leverage a global supply chain and manufacturing network that spans four continents and includes more than 20 facilities.

  • How is the Pfizer-BioNTech COVID-19 vaccine being distributed?

    Pfizer has activated its extensive U.S. and European manufacturing network, including thousands of highly skilled U.S. workers in multiple states and localities, to prepare to produce the COVID-19 vaccine. We currently have the capacity to produce 4 billion doses annually, pending demand.

  • What is the path of a vaccine from Pfizer’s facilities to where it’s distributed to patients?

    We have developed detailed logistical plans and tools to support effective vaccine transport, storage and continuous temperature monitoring. Our distribution is built on a flexible just-in-time system which will ship the frozen vials to the point of vaccination.

    Our distribution approach will be to largely ship from our Kalamazoo and Puurs sites direct to the point of use (POU). However, we will also be using our existing distribution centers for the COVID-19 distribution in Pleasant Prairie, WI and in Karlsruhe, Germany. These distribution centers will have a dedicated area designated to store product that is not going direct from our Kalamazoo or Puurs sites to POU.

    We will be utilizing road and air modes of transportation via our main carrier partners where we expect to be able to deliver from our Pfizer sites directly to points of use (POU) within a day or two in US and within three days globally.

  • How will Pfizer maintain vaccine integrity during distribution?

    Pfizer is a proven, reliable multinational vaccine producer, supplying vaccines to more than 165 countries. Today, Pfizer manufactures more than 200 million doses of Pfizer vaccines annually and is one of the largest sterile injectables suppliers in the world, producing more than 1 billion sterile units per year. We have experience working with customers in all markets to ensure success.

    We have years of proven experience in supply chain and cold chain management, and we are accelerating the development of innovative technologies to further advance our capabilities as a supply chain leader.

    Our track record gives us confidence in our ability to quickly scale and manufacture and distribute large quantities of a high-quality COVID-19 vaccine, leveraging multiple sites in the US and Europe.

    We have also developed packaging and storage innovations to be fit for purpose to meet the needs of our global network.

    We have developed detailed logistical plans and tools to support effective vaccine transport, storage and continuous temperature monitoring. Our distribution is built on a flexible just-in-time system which will ship the frozen vials to the point of vaccination.

    The intent is to utilize Pfizer-strategic transportation partners to ship by air to major hubs within a country/region and by ground transport to dosing locations.

  • What is a “cold chain”?

    “Cold chain” is how the temperature of perishable products are managed in order to maintain quality and safety from end to end in the distribution process. Cold chain is used for consumer products like ice cream and other frozen foods, as well as medicines and vaccines.

  • How is Pfizer utilizing a cold chain process to distribute its vaccine?

    We have developed packaging and storage innovations to be fit for purpose to meet the needs of our global network. We have specially designed, temperature-controlled thermal shippers utilizing dry ice to maintain recommended temperature conditions for up to 10 days unopened. The intent is to utilize Pfizer-strategic transportation partners to ship by air to major hubs within a country/region and by ground transport to dosing locations.

  • How can you prevent a cold chain failure?

    We have specially designed, temperature-controlled shippers utilizing dry ice to maintain recommended temperature conditions up to 10 days unopened. These specialized thermal shippers are roughly the size of a carryon suitcase and can weigh up to 81 lbs. fully loaded.

    We will utilize GPS-enabled thermal sensors in every thermal shipper with a control tower that will track the location and temperature of each vaccine shipment across their pre-set routes. These GPS-enabled devices will allow Pfizer to proactively prevent unwanted deviations and act before they happen.

  • How do hospitals and pharmacies keep vaccines cold?

    Once a POU receives a thermal shipper with our vaccine, they have three options for storage:

    • Ultra-low-temperature freezers, which are commercially available, can extend shelf life for up to 18 months.
    • The Pfizer thermal shippers, in which doses arrive, can be used as temporary storage units by refilling with dry ice every five days for up to 30 days of storage.
    • Refrigeration and freezer units are commonly available in hospitals and pharmacies. The vaccine can be stored for up to 10 weeks at refrigerated 2-8°C conditions, the standard temperature of a refrigerator.

    The shipper can maintain temperature for 10 days unopened which allows for transportation to markets globally to ensure all patients have access. Once opened, and if being used as temporary storage by a vaccination center, then it can be used for a total of 15 days with re-icing every five days.

    After storage for 15 days in the Pfizer thermal shipper, vaccination centers can transfer the vials to 2-8°C storage conditions for an additional five days, for a total of 20 days. Once thawed and stored under 2-8°C conditions, the vials cannot be re-frozen or stored under frozen conditions.

    The various storage options at the POU allow for equitable access to the Pfizer vaccine to areas with differing infrastructure.
