Question

Which of the following vaccines is kept at the lowest level? 

• A. OPV
• B. DPT
• C. Hep B
• D. Rota

Hint:

The OPV requires the lowest temperature in the vaccine cold chain, so ensure it is stored at -20°C to -30°C for optimal efficacy.

Answer 1

The Correct Option is A

The Oral Polio Vaccine (OPV) is kept at the lowest temperature compared to other vaccines in the cold chain, typically between -20°C to -30°C. OPV is a live attenuated vaccine, and it requires storage in a deep freezer to maintain its potency and effectiveness.
- DPT (Diphtheria, Pertussis, and Tetanus) vaccine requires refrigeration at 2-8°C.
- Hepatitis B vaccine also requires refrigeration at 2-8°C, but not as low as OPV.
- Rota (Rotavirus) vaccine is a live vaccine, but it is typically stored at -15°C to -25°C, which is not as low as OPV.
Therefore, OPV is the vaccine that is kept at the lowest temperature in the cold chain.
