This creates a challenge for distribution and storage, as most hospitals can only refrigerate at around -2 to -8 degrees. "If a vaccine has a two-year shelf life at refrigerator temperatures, then the manufacturer actually needs to put the vaccine at that refrigerated temperature for two years and see if at the end the product is still effective," Kristensen explains. The Centers for Disease Control and Prevention, the federal agency in charge of vaccine distribution and decisions about which groups receive the first shots, has tried to discourage health departments and hospitals from going out and buying expensive freezers to accommodate the Pfizer vaccine.

Moderna’s vaccine, mRNA-1273, is expected to remain stable at standard refrigerated conditions of 2°C to 8°C for up to 30 days within the 6-month shelf life. The first step, Liu says, was to modify the mRNA nucleosides — the "building blocks" of the RNA vaccine. This graphic from Orbcomm shows the real-time temperature and location monitoring of a refrigerated load.

Just as there are ways to keep the chocolate from melting into goo, there are things the drugmakers did to protect their COVID-19 vaccines. They have a shelf life of 24 months when refrigerated, but may also be stored in a freezer. Christine Finley, the immunization manager in Vermont finalizing that state's distribution plan, says it makes sense to think about distributing Pfizer's vaccine to larger population centers, not just because of its temperature, but because the smallest amount you can order is 975 doses (usually it's more like 100 doses or fewer).

One of the front-runners in the vaccine race — the one made by Pfizer — needs to be kept extremely cold: minus 70 degrees Celsius, which is colder than winter in Antarctica. This, explains Kristensen, is useful for health care workers in the field, "because now the vaccine doesn't need to go in and out of the refrigerator each time it's administered.". This would be like changing the chocolate recipe so it's not quite so melty. "Given the urgent need for these COVID-19 vaccines, manufacturers will likely begin releasing them with shorter shelf lives and then they'll expand the shelf life durations as they gather more data.". “All those steps need to happen, and [when] they do, then people like me and many other infectious disease experts will line up for the vaccine,” Dr. Boucher says. Even if we get the vaccine we need, we mustn’t fail to get it to the people who need it. "But if they can prove that the vaccine can be kept at refrigerated temperatures for some time after being removed from frozen storage, that helps facilitate distribution and administration out to more remote areas and to specific groups of people.". People aged over 50 in England are being urged to get a flu jab, as ministers hope for a mass roll-out of a Covid-19 vaccine next year. Post was not sent - check your email addresses!

Pfizer has provided these details to the CDC about shipping and storage of their candidate: the vaccine can be shipped in “dry ice pack” boxes, but that dry ice will need to be replenished within 24 hours of receipt. Those two vaccines need to be stored long-term in very low temperatures. Both the Moderna and Pfizer vaccine candidates use a new approach to unlock the body's immune defenses. Even that presents challenges, though — a Pfizer scientist told a CDC advisory council in August that it's not supposed to be opened more than twice a day and needs to be closed within one minute of opening. Given the demand, if both Pfizer and Moderna's vaccines are authorized around the same time, states will figure out how to use both in different settings. "We still need to show that they're safe and they're effective and we need to build trust with the public — so there's still a ways to go, but this is good news. "So your chemical reactions — the enzymes that break down RNA — are going to happen more slowly." Since there will be limited vaccine doses at first, immunization managers across the country will need to have plans to distribute any and all vaccine doses that are available. Data sources include IBM Watson Micromedex (updated 2 Nov 2020), Cerner Multum™ (updated 2 Nov 2020), … While that can be a challenge in some parts of the world, as they go to great lengths to maintain the cold chain for vaccines, in developed countries, it typically means knowing whether to put the vaccine in the refrigerator or the freezer. She says you would start at ultra-cold temperatures, then try regular freezer temperature, then refrigerator temperature, and finally room temperature. Pingback: Which Vaccines Need to be Frozen? Moderna’s COVID-19 vaccine shines in clinical trial, Novavax posts coronavirus vaccine contract that government didn’t disclose, Pfizer says COVID-19 vaccine is looking 90% effective.
