The vaccine can be given to those who have reached the age of 26 but have not yet reached the age of 27. Currently, the appropriate age for the vaccine is 9-45 years old.
The nine-valent vaccine is divided into three doses of vaccination, the second dose should be at least one month apart from the first dose, and the third dose should be at least three months apart from the second dose, and it is best to complete the three doses of the vaccine within one year.
Vaccination should be avoided during pregnancy; if a woman is pregnant or planning to become pregnant, it is recommended that vaccination be delayed or interrupted and repeated after the end of pregnancy. If pregnancy occurs unexpectedly after vaccination, discontinue the uncompleted dose; no intervention is necessary for those who have completed the vaccination. Use with caution in lactating women.
Adverse reactions such as fever, nausea, dizziness, fatigue and diarrhea may occur in some patients after vaccination with the nine-valent vaccine. The degree of reaction is generally mild to moderate and can be relieved on its own within a short period of time. If there are serious adverse reactions such as respiratory distress and urticaria, patients should go to the hospital in time.
