Which Vaccines Are Heat Sensitive?

All vaccines are sensitive to extreme heat and extreme cold and require both proper vaccine storage and management to avoid any loss of potency. Temperature sensitivity of vaccines is vital to understand. Immunization is the most effective and economical public health measure against infectious diseases.

Which vaccines are more susceptible to cold temperatures?

Some of the most widely used vaccines are freeze-sensitive, including:

  • Diphtheria.
  • Tetanus.
  • Pertussis.
  • Liquid Haemophilus influenzae type b (Hib)
  • Hepatitis B.

Who is responsible for correct storage of vaccines?

It is the responsibility of the person transporting and administering vaccines to assure themselves that the vaccine has been stored between 2-8°C prior to administration. This includes staff administering vaccines to patients outside of the practice, for example in their own home/care home setting.

Which environmental conditions destroy vaccines?

Vaccines are fragile, biological substances. They can become less effective or even destroyed if they are exposed to temperatures outside the recommended storage range — between +2°C and +8°C. This ‘cold chain’ begins when the vaccine is made and ends when the vaccine is administered.

How can freezing temperatures affect vaccines?

Effectiveness cannot be guaranteed for vaccines unless they have been stored at the correct temperature. Freezing may cause deterioration of the vaccine and lead to hairline cracks in the ampoule, vial or pre-filled syringe which could potentially allow the contents to become contaminated.

Why is cold chain important for vaccines?

This is called a cold chain. Vaccines must be continuously stored in a limited temperature range – from the time they are manufactured until the moment of vaccination. This is because temperatures that are too high or too low can cause the vaccine to lose its potency (its ability to protect against disease).

Which vaccines should not be frozen?

DPT, DT, dT, TT, Hepatitis B and typhoid contains such adjuvant and so can not be frozen. 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.

How long can Pfizer vaccine be at room temperature?

Mixed Vaccine

(2°C to 25°C ) for up to 6 hours.

Does boostrix need to be refrigerated?

Boostrix should be stored in a refrigerator (2°C – 8°C). Do not freeze. Discard if vaccine has been frozen. Protect from light.

Which vaccine is least sensitive to heat?

Polio vaccine is the most sensitive to heat, while tetanus toxoid is the least sensitive. Vaccines do not change their appearance when potency is lost. A complete laboratory test is the only means to assess whether a vaccine in a vial has lost its potency. The following vaccines are listed in order of heat sensitivity.

What happens if flu vaccines are not refrigerated?

If flu vaccines are not refrigerated, have been frozen, or have been affected by a temperature excursion event, they will become less effective and potentially unsafe. Do not administer these vaccines to patients.

Who is responsible for following and maintaining cold chain?

Immunisation providers are responsible for ensuring all staff are trained in vaccine storage and cold chain management. The NSW Health Vaccine Storage and Cold Chain Management online training module should be used to facilitate staff education to equip staff to effectively manage the cold chain.

How long can flu vaccine be left out of refrigerator?

It must be refrigerated at temperatures below 4 C at which temperature, it slowly deteriorates after two years. At room temperature, it retains its stability at 25 C for up to one month.

Can a blood fridge be used to store vaccines?

Blood refrigerators are specifically designed to store blood products at a controlled temperature between +2°C and +6°C. This means that, if necessary, it is acceptable to store vaccines and blood products in the same refrigerator.

How long can flu vaccine be at room temperature?

Refrigerator: Between 2°C and 8°C (36°F and 46°F) for 2 hours and 30 minutes • Room temperature: Between 15°C and 25°C (59°F and 77°F) for 1 hour • Vials that have not been punctured may be kept between 8°C and 25°C (46°F and 77°F) for up to 12 hours.

What is the recommended temperature for safe keeping of vaccines?

Temperature Ranges. Refrigerators should maintain temperatures between 2°C and 8°C (36°F and 46°F). Freezers should maintain temperatures between -50°C and -15°C (-58°F and +5°F).

What temperature should BCG vaccine be kept?

The intact vials of BCG VACCINE should be stored refrigerated at 2–8°C (36–46°F). This agent contains live bacteria and should be protected from direct sunlight.

How long are vaccines stable at room temperature?

The stability at refrigerated conditions allows for storage at most pharmacies, hospitals, or physicians’ offices. Room Temperature for Vaccination: Once the vaccine is removed from the refrigerator for administration, it can be kept at room temperature conditions for up to 12 hours.

Is boostrix a tetanus vaccine?

Indication: For active booster immunization against tetanus, diphtheria and pertussis in individuals 10 years of age and older.

Why does the Pfizer vaccine have to be stored at such a low temperature?

Dr. Cooke: The reason the Pfizer and Moderna COVID-19 vaccines need to be kept so cold is because of the mRNA used in these vaccines. Leveraging mRNA technology has been pivotal in developing a safe, effective vaccine so quickly, but mRNA itself is incredibly fragile — it gets broken down very rapidly and easily.

How long is Pfizer good for once punctured?

Unpunctured vials:

Vaccine may be stored at refrigerated temperatures for up to 1 month (31 days). Any time used for transport counts against the 31-day time limit for storage at these temperatures.

Is Pfizer Covid vaccine 2 doses?

What You Need to Know. If you receive a Pfizer-BioNTech or Moderna COVID-19 vaccine, you will need 2 shots to get the most protection. COVID-19 vaccines are not interchangeable. If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot.
