Which of the following vaccines is commonly stored in a refrigerator?

The Hepatitis B vaccine is typically stored in a refrigerator, as it requires cold chain storage to maintain its efficacy. Vaccines like the Hepatitis B vaccine need to be kept at temperatures between 2°C and 8°C (36°F and 46°F) to preserve their potency and effectiveness for the immunization process.

In contrast, vaccines such as the Measles, mumps, rubella vaccine and the Herpes zoster vaccine can be stored under different conditions. The Measles, mumps, rubella vaccine is often refrigerated as well, but certain formulations may have specific storage requirements that differ. The Varicella vaccine, on the other hand, is usually stored in a freezer rather than a refrigerator.

Understanding the proper storage requirements for vaccines is crucial in pharmacy practice to ensure that all vaccines administered to patients maintain their effectiveness, thus providing the intended protection against diseases.
