Flucelvax, a preservative-free influenza vaccine, can be stored between 35° F and 46° F (2° C to 8 °C). It should not be frozen. The vaccine should never exceed the upper temperature limit of 46 °F (8 °C).

If the vaccine is allowed to warm up for more than 48 hours, it must be discarded, as its potency may have been compromised. Vaccines that have exceeded their expiration date must also be discarded.

In summary, Flucelvax should always remain refrigerated unless being used immediately after preparation. If out of the refrigerator for longer than 48 hours or past its expiration date, it must be discarded.

How Long Can Flucelvax Be Out of Refrigerator? Learn the Fact!

Flucelvax is a flu vaccine that is typically stored in a refrigerator to maintain its effectiveness. When it comes to vaccines, it’s crucial to adhere to proper storage guidelines to ensure their potency and efficacy.

The good news is that it can be stored at room temperature, so no need to worry about keeping it in the refrigerator all the time!

While Flucelvax must remain refrigerated during transport, once it has been received by your healthcare provider they can store it safely at room temperature (up to 77° F or 25° C) for up to 10 days without any loss of potency.

If Flucelvax has been removed from the refrigerator, it should not be left at room temperature for an extended period. The exact duration it can be kept out of the refrigerator may vary depending on factors like temperature, light exposure, and the specific product formulation.

However, as a general rule of thumb:

  • Flucelvax should be administered as soon as possible after being removed from the refrigerator.
  • If left at room temperature, it is advisable to use the vaccine within a few hours (usually up to 2 hours) to minimize the risk of losing potency.

After this time frame, the vaccine’s effectiveness may start to degrade.

It’s essential to consult with a healthcare professional or pharmacist for specific guidance if you suspect that Flucelvax has been left out of the refrigerator for an extended period or if you have any concerns about its effectiveness.

They can provide you with the most accurate information and recommendations for your specific situation.

• Between 2 hours to 8 hours – depending on the type of vaccine and temperature outside.

• After 8 hours, discard the vaccine as it could be damaged or compromised in some way.

• If possible, keep vaccines between 2°C – 8°C (35°F – 46°F).

It is best practice not to leave a vaccine out of refrigeration for more than two hours at any given time if you wish to ensure its safety and efficacy.

What Happens If Flu Vaccine is Not Refrigerated?

If the flu vaccine is not refrigerated, it may become less effective or even ineffective. This can lead to a greater risk of developing serious complications from the virus.

Here are some important points to remember about storing and transporting the flu vaccine:

  • Keep in refrigerator between 2-8 degrees Celsius at all times
  • Do not freeze; this could damage the vaccine
  • Vaccine should be transported in coolers with frozen ice packs or other cooling agents

Failure to follow these guidelines could cause adverse effects when administering the vaccination. It is important that healthcare providers properly store and transport vaccines for maximum effectiveness.

How long can flu vaccine be left unrefrigerated?

The flu vaccine, including various formulations such as Flucelvax, should be stored and handled according to specific temperature guidelines to maintain its effectiveness. Leaving the flu vaccine unrefrigerated for an extended period can lead to a loss of potency.

Refrigerated Storage: The flu vaccine should be stored in a refrigerator between 36°F and 46°F (2°C to 8°C). When stored at this temperature range, the vaccine can maintain its potency for the duration indicated on the product label.

Limited Room Temperature Exposure: If the flu vaccine is briefly removed from the refrigerator, it can generally be kept at room temperature (usually up to 77°F or 25°C) for a short period. This period can vary depending on the specific vaccine formulation and manufacturer, but it’s usually recommended not to exceed a few hours (typically up to 2 hours) at room temperature.

Avoid Freezing: Do not freeze the flu vaccine. Freezing can damage the vaccine and render it ineffective.

Use Promptly: Whenever possible, administer the vaccine promptly after removing it from the refrigerator to ensure maximum efficacy.

It’s essential to follow the storage and handling instructions provided by the manufacturer and consult with healthcare professionals or pharmacists for specific guidance related to the particular flu vaccine you are using.

Is Flucelvax a Live Vaccine?

No, Flucelvax is not a live vaccine. It is an inactivated influenza (flu) vaccine made from flu virus strains and given as a shot. The inactive viruses are killed with a chemical treatment, so they cannot cause infection or illness like the live vaccines can.


In conclusion, Flucelvax can remain stable when stored between 2 °C and 8 °C for up to 6 months. It is important that it is not exposed to temperatures outside this range – either higher or lower – as doing so could render the vaccine ineffective.

Furthermore, the vial should be used within 28 days after first being removed from refrigeration, in order to ensure optimal potency of the vaccine.

By following these guidelines and keeping a close eye on storage conditions, healthcare providers can ensure that their patients are receiving an effective dose of Flucelvax.
