It is still possible to get HFMD with the EV71 vaccine. The EV71 vaccine is a protective vaccine against enterovirus 71. Most cases of HFMD are caused by EV71, but infections with viruses such as Coxsackie A16 can also cause HFMD. Therefore, vaccination against EV71 alone does not guarantee that you will not get HFMD again, but if you get infected again, you can reduce its complications and the chance of serious illness. It is also important to cultivate hygienic habits in your child’s daily life and to wash your hands frequently. During HFMD epidemics, avoid going to crowded, airtight public places and avoid contact with people who already have HFMD. If you have HFMD, it is recommended that you seek medical attention in a timely manner to receive standardized diagnosis and treatment, and pay attention to isolation to avoid spreading the disease to others.
