Question
A child developed symptoms such as fever and drooling after receiving the hand, foot, and mouth disease vaccine. The diagnosis was hand, foot, and mouth disease. The parent questioned whether it was a misdiagnosis or the vaccine was ineffective. Can a child still get hand, foot, and mouth disease after vaccination?
Answer
Receiving the hand, foot, and mouth disease vaccine can provide some protection, but it is not absolute immunity. If a child is in an environment with a high risk of viral infection or has a weak immune system, they may still be susceptible to the virus. It is recommended that parents keep their children away from other children with hand, foot, and mouth disease and encourage them to exercise actively to enhance their own resistance. Generally, this will not have a serious impact on the child’s health.
