The EV71 vaccine, also known as the hand, foot and mouth disease vaccine, is generally priced at about 200 yuan for one dose and requires two doses. However, due to regional differences, the price may fluctuate, and the specific price can only be determined by consulting the local vaccination department. It should be noted that the EV71 HFMD vaccine is only for severe HFMD caused by EV71 infection, but it does not mean that you will not get HFMD after vaccination, because there are dozens of enteroviruses that can cause HFMD. Therefore, during an HFMD epidemic, parents should help their children with personal hygiene, avoid going to crowded and unventilated public places, and wash their hands as soon as possible after sharing toys with others before eating.
