What is thermostable vaccine?

Hear this out loudPauseVBI’s proprietary thermostable technology platform, known as LPV™, creates lipid vesicles (small lipid bubbles) which surround and enclose the antigen (active component) of a vaccine. These structures are then ‘freeze-dried’ in a process designed to improve vaccine stability.

What causes change in stability of vaccines?

Hear this out loudPauseVaccine instability can be caused by light, heat, radiation, changes in the environment, or reactions with the container or with other components in the mixture. Even when optimal conditions are maintained, potency may decline gradually as time passes after production.

Why are vaccines sensitive to temperature?

Hear this out loudPauseVaccines are sensitive biological substances that can lose their potency and effectiveness if they are exposed to temperatures (heat and/or cold) outside of the required temperature range for the specific product (i.e., ultra-low or frozen temperatures) or when exposed to light.

This includes staff administering vaccines to patients outside of the practice, for example in their own home/care home setting.

What are the storage conditions and stability of official vaccines?

Hear this out loudPauseStore refrigerated vaccines at temperatures between 2°C and 8°/36°F and 46°F. Set the refrigerator thermostat midrange to achieve a temperature of about 5°C/40°F. Do not expose refrigerated vaccines to freezing temperatures. Store frozen vaccines at temperatures between -50°C and -15°/-58°F and +5°F.

Which is the highly stable vaccine?

Hear this out loudPauseBacteriophage lambda is a highly stable DNA vaccine delivery vehicle. Vaccine.

Which vaccines are sensitive to heat?

Hear this out loudPausePolio vaccine is the most sensitive to heat, while tetanus toxoid is the least sensitive. Vaccines do not change their appearance when potency is lost.

Which vaccines are sensitive to freezing?

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

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

Which vaccine Cannot be given together?
