Hand, foot and mouth vaccine is necessary. Hand, foot and mouth disease is an acute infectious disease caused by a variety of enteroviruses. Hidden infections and patients are the main source of infection, which can be transmitted through the digestive tract, respiratory tract and other channels, and can also be infected after contact with the affected child’s towels, toys, tableware, bottles and other personal belongings, and the contagiousness is relatively high. Therefore, it is necessary to get vaccinated against HFMD, especially for infants and young children under the age of 5, to prevent children from being infected to the maximum extent possible. Young children can be vaccinated with the HFMD vaccine after they reach 6 months of age. The vaccine is divided into two doses, with an interval of about 28 days in between, but the HFMD vaccine is not included in the national legal preventive vaccination scope, and you need to pay for the vaccine at your own expense. It is recommended that children of the appropriate age be vaccinated in a timely manner to prevent the occurrence of infectious diseases.
