By contrast and for comparison, the influenza vaccine can be stored for months in refrigerators in single-dose vials — easing distribution significantly. Second, there will eventually be a second generation of COVID mRNA vaccines, and this next generation will likely overcome the ultra-cold storage challenge. In fact, our mRNA is stable for 6 months in a refrigerator, and we've even has success shipping it at room temperature overseas. What does the requirement for ultra-cold storage mean for vaccine availability?

Regarding the correct method of storage of vaccine in the refrigerator in the clinic, why do you recommend that killed vaccines like OPT, TT, OT and Typhoid be placed on the second shelf and freeze dried vaccine such as varicella be placed on the third shelf?
Other freeze dried vaccines such as measles; MMR are to be kept either in the freezer or in the first shelf. Anita Chandna, Plot No. Different vaccines due to presence of antigens have different heat lability, i. Further some of the vaccines contain adjuvant which is Aluminum salts. If these vaccines are frozen, Aluminum salts gets flocculated and most of the antigen gets fixed into those floccules.
So that vaccine looses that much potency. Lyophilized or powder type of vaccines do not freeze as they have no liquids in it and so storage in freezer compartment or lower shelves do not make difference.
In the freezer compartment we can be sure of maintenance of temperature. To protect the vaccine supply, vaccine should be delivered directly to the facility where it will be used. However, sometimes, vaccine needs to be transported to an off-site or satellite facility for an event like an on-site vaccination clinic.
Transport may also be required during emergencies such as long-term power outages or flooding or other natural disasters that can put the vaccine supply in jeopardy. In these instances, certain actions must be taken to protect the vaccine supply. Vaccine transport to off-site or satellite facilities is different from both shipping and emergency transport.
Shipping usually involves a professional carrier and a long distance and time frame for moving vaccines between locations. Transport involves the movement of vaccine over a short time frame and distance between providers. Depending on the situation, transport recommendations may vary. A facility should have a supply of materials needed for transport of the largest annual vaccine inventory.
Soft-sided containers specifically engineered for vaccine transport are acceptable and may be part of a qualified container and packout system. Commercially available soft-sided food or beverage coolers should not be used because most are poorly insulated and likely to be affected by room or outdoor temperatures. A TMD for each transport container should be used during transport, as well as appropriate coolants and transport materials according to the specific transport system s being used.
The same shipping containers the vaccines were initially shipped in may be used for emergency transport as a last resort only. If an emergency can be anticipated e. Immediately upon arrival at the off-site location, vaccines should be stored in an appropriate storage unit with a TMD. Follow recommended guidelines for monitoring and recording storage unit temperatures:. If vaccines cannot be stored in an on-site storage unit, they should be kept in the portable vaccine storage unit using the following guidance:.

Transport of Refrigerated Vaccines to Off-Site or Satellite Facilities Best practices for transport include: The total time for transport alone or transport plus clinic workday should be a maximum of 8 hours. Transport diluents with their corresponding vaccines to ensure there are always equal amounts of vaccines and diluents for reconstitution.
Transport only the amount of vaccine needed for the workday. If a noncommercial vehicle must be used, place the transport containers in the passenger compartment, not the trunk. Transport of Vaccines in Emergencies In addition to the actions outlined above, in an emergency situation: Contact an alternative vaccine storage facility before packing any vaccine to confirm it can accept vaccines for storage.
Note any protective measures in place at the time of the event water bottles, battery-powered TMD, transport to alternative facility, etc. Only open the vaccine storage unit door when ready to pack vaccine in transport containers or when power has been restored. Storing Vaccines at the Destination Immediately upon arrival at the off-site location, vaccines should be stored in an appropriate storage unit with a TMD.
If vaccines cannot be stored in an on-site storage unit, they should be kept in the portable vaccine storage unit using the following guidance: Place a TMD preferably with a probe in a thermal buffer as close as possible to the vaccines and check and record temperatures hourly. Keep the container closed as much as possible. Top of Page. Get Email Updates. To receive email updates about this page, enter your email address: Email Address.
