The commonly administered measles, mumps, rubella (MMR) vaccine can be stored either frozen or refrigerated, while the MMRV vaccine that also contains the live varicella virus must be frozen.
- BCG is a live attenuated vaccine.
- It contains weak bacteria. Therefore, it is stored at a temperature of 2–8°C (36–46°F).
- If the live vaccines are frozen then the weak bacteria is destroyed. Therefore, the vaccine is not frozen.
- The high temperature will also destroy the bacteria.
