How to Protect COVID-19 Vaccines with the Correct Vaccine Storage Temperatures

 

With coronavirus (COVID-19) vaccines in short supply, your practice cannot afford to let vaccines go to waste. If your inventory falls out of the required vaccine storage temperatures, vaccines can become damaged, ineffective, and even unsafe to use. This can slow down your immunization program and put your patients at risk.

To add to these challenges, you need to store and manage different vaccine manufacturers at different temperatures. The current COVID-19 vaccine temperature ranges may also be much colder than what you’re used to working with. Although your staff members can help you keep an extra eye on this inventory, manual processes prevent your practice from focusing on patient care and can result in human error.

Read on to learn about the vaccine storage temperatures of the authorized COVID-19 vaccines and how you can protect your valuable inventory until your patients are ready and able to receive their vaccination.

Why Temperature Is Key

Like most vaccines, the COVID-19 vaccines need to be stored at specific temperatures to maintain their efficacy. Although unpunctured Johnson & Johnson vials can be safely refrigerated for 3 months, longer-term vaccine storage temperatures for Pfizer-BioNTech and Moderna vaccines are much colder. This is because these vaccines contain messenger RNA (mRNA), a genetic material found in all cells that is used to create proteins. 

After receiving a mRNA COVID-19 vaccine, your body uses the mRNA to create its own version of the spike protein, a component of the outer shell of the COVID-19 virus. This spike protein triggers an immune response and teaches your immune system to fight any future exposure to the virus. 

MRNA vaccines can be synthesized in a laboratory without a large production of the virus. This explains why they were the first to be authorized. However, mRNA is a fragile material that breaks down quickly and easily. Cold vaccine storage temperatures are required to keep the mRNA stable until it’s ready to be used. 

Future COVID-19 vaccines may not require such extreme temperature ranges, especially if they do not contain mRNA. Nevertheless, it’s critical to adhere to all the different vaccine storage temperatures to keep vaccines safe and effective.

Why Does the Pfizer-BioNTech Vaccine Require Colder Storage Temperatures Than the Moderna Vaccine?

The Pfizer-BioNTech vaccine needs an ultra-cold chain, which has added to the logistical challenges of shipping and storing this vaccine. But there are good reasons for these ultra-cold vaccine storage temperatures

As the first authorized vaccine, Pfizer-BioNTech had to ensure vaccine stability. Without more time to collect data, the manufacturer went with the safest option: recommending an ultra-cold vaccine temperature range. With more trials, the required vaccine storage temperatures may change. In fact, the FDA has recently allowed more flexible storage for the Pfizer-BioNTech vaccine. 

Although there may be more changes in the future, it’s important to maintain the vaccine temperature ranges that are currently recommended. Even though the proteins of both the Pfizer-BioNTech and Moderna vaccines were derived from the same material, they are not the same and may still require very different conditions.

As each manufacturer has created a COVID-19 vaccine that has different temperature requirements, it’s essential to maintain the specific storage temperatures for the vaccine your practice is using. The different manufacturers are not interchangeable and temperature is key to vaccine efficacy. 

You should not store COVID-19 vaccines in a combination unit with other vaccines that require different storage temperatures. If any vials fall out of these vaccine temperature ranges, do not use them. Dispose all vaccines if they are not used within their expiry times or have been affected by a temperature excursion event at any point during storage.

Pfizer-BioNTech Vaccine Storage Temperature

The Pfizer-BioNTech vaccine can be stored between -80 and -60°C until the expiration date. If you keep the vaccines in the dry ice thermal shipper, replenish the dry ice on day 1 and day 5 of the storage period. You can also store this vaccine in a freezer unit between -25 and -15°C for up to 2 weeks.

This vaccine needs to be thawed and reconstituted before use. You can thaw the vials in a refrigerator unit between 2 and 8°C for 3 hours, or at room temperature (up to 25°C) for 30 minutes. Once the vaccines have been thawed and reconstituted, they cannot be refrozen. They can, however, stay safely in the refrigerator for up to 31 days.

Store punctured vials in a refrigerator unit between 2 to 8°C for up to 5 days or at room temperature (up to 25°C) for no more than 6 hours to prevent bacterial contamination. 

Moderna Vaccine Storage Temperature

The Moderna vaccine can be stored in a freezer unit between -25 and -15°C until the expiration date. You can also store the vaccine in a refrigerator unit between 2 to 8°C for up to 30 days.

If stored in a freezer unit, this vaccine needs to be thawed before use. You can thaw the vials in a refrigerator unit between 2 and 8°C for 2 hours and 30 minutes, or at room temperature (up to 25°C) for 1 hour. Once the vaccines have been thawed, they cannot be returned to the freezer.

Store punctured vials in a refrigerator unit between 2 to 8°C for up to 30 days or at room temperature (up to 25°C) for no more than 12 hours to prevent bacterial contamination. 

Johnson & Johnson Vaccine Storage Temperature

The Johnson & Johnson vaccine can be stored in a refrigerator unit between 2 to 8°C until the expiration date. Once the vials have been punctured, they can be stored in the refrigerator for up to another 6 hours. After this time, if the vaccines have not been used, they must be discarded.

This vaccine can also be stored at room temperature for up to 12 hours before puncture and for up to 6 hours after puncture.

How Your Practice Can Protect Vaccines

During this busy immunization program at your practice, you need a vaccine storage and monitoring system you can rely on. This will ensure that you keep your vaccines safe and effective until you’re able to administer them to your patients. The following technology can help you protect your vaccines by ensuring the correct vaccine storage temperatures.

Vaccine Temperature Monitoring

Manual vaccine temperature monitoring requires time and vigilance. A member of your team needs to log the vaccine storage temperature in the morning and evening each day. The COVID-19 vaccine temperature ranges are more extreme and critical to efficacy, which makes monitoring even more important.

Temperature excursion events can still take place between these daily check-ins and lead to even more manual action. All out-of-range temperatures need to be logged and looked into. Your team member may also need to contact the vaccine manufacturer or local or state health department to determine whether the vaccines can still be used.

The AccuShelf Inventory Management System provides integration with digital data loggers which can be attached to any cold storage device, including dry ice containers and ultra-low freezers. Ultra-low and standard vaccine temperature monitoring allows you to maintain the correct COVID-19 vaccine storage temperatures and track movement between storage units. With real-time temperature alerts, you can react quickly to any temperature excursions that might put your vaccines at risk.

Vaccine Refrigerator with Battery Backup

Temperature excursion events can stem from poor quality storage equipment, a team member accidentally leaving the storage unit door open, or from power outages. Whatever the cause, your inventory falls out of the vaccine temperature ranges and may have to be discarded.

In addition to its doorless design that prevents human error, the Accuvax Vaccine Refrigerator with Battery Backup provides up to 15 hours of vaccine storage protection. The built-in battery pack ensures your vaccines stay at the correct vaccine storage temperatures to give you extra peace of mind during this stressful time.

Purpose-Built Vaccine Storage

While household combination units may have provided sufficient vaccine protection in the past, these units are unable to reach and maintain COVID-19 vaccine storage temperatures. Although these devices have both a freezer and refrigerator compartment, they cannot store a variety of vaccines at different temperature ranges. What’s more, all stock loading and rotation is done by hand to ensure vaccines are stored correctly and used before they expire.

To store vaccines safely and effectively, you need a purpose-built vaccine storage unit that can support your entire inventory, no matter how many different vaccine storage temperatures you need to accommodate. A custom-built vaccine storage system will also allow you to scale up and pivot when medical needs change and expand in the future.

As the emerging standard in the industry, the AccuVax Vaccine Management System can store refrigerated and frozen vaccines safely within the same unit and guarantees temperature control. The technology automatically rotates your inventory by expiry date to prevent unnecessary waste. With notifications and real-time dose level data, you know exactly how to manage your vaccines to provide your patients with effective vaccination when they need it.
