Question

Can the polio vaccination tablets for my baby be consumed after being stored at home for a month? Will they lose effectiveness and affect the preventive function? Urgent!

Answer

Polio vaccines are heat-sensitive and should be stored under low-temperature conditions. The shelf life is 2 years below -20℃ and 1 year between 2~8℃ (the vaccine packaging label only specifies one storage temperature and shelf life). You need to check which storage temperature is written on the outer packaging. It is recommended to consume them immediately. If storage is necessary, please check the storage temperature on the outer packaging and store them under low temperature conditions.
