Question
Can the polio sugar pill for babies be stored at home for a month before consumption? Will it become ineffective and affect the preventive effect? Urgent!
Answer
The polio vaccine is sensitive to heat and should be stored under low-temperature conditions. The shelf life is 2 years below -20°C and 1 year between 2~8°C (the vaccine packaging label only specifies one storage temperature and shelf life). You should check which storage temperature is indicated on the outer packaging. It is recommended to take it immediately. If storage is necessary, make sure to check the storage temperature indicated on the outer packaging, and store it in a low-temperature environment.
