Question

After being stored at home for a month, can the polio sugar pills still be safely given to the baby? Will they lose their preventive effect due to prolonged storage? Urgent!

Answer

The polio vaccine is sensitive to high temperatures and should be stored under low-temperature conditions. At temperatures below -20°C, the vaccine can be stored for 2 years; under conditions of 2~8°C, the shelf life is 1 year (specific storage duration and temperature should be referred to the label on the vaccine package). You should inspect the outer packaging of the vaccine to confirm the storage temperature. If storage is necessary, ensure that the temperature meets the requirements specified on the package. If storage is necessary, make sure the temperature meets the requirements on the package.
