Vaccinations are not recommended for 3 months after surgery. The nationally prescribed basic immunization vaccines for children can be postponed in order: e.g., diphtheria, polio sugar pill, measles, rubella, mumps, hepatitis B vaccine, etc. Other vaccines required by seasonal and epidemiological factors, such as encephalitis B, influenza, influenza, and hepatitis A vaccines, can also be postponed until 3 months after surgery. In case of high fever and increased respiratory and heart rate after vaccination, contact your local pediatrician promptly and explain what kind of medications you are taking and what kind of cardiac surgery you have had, and provide symptomatic treatment if necessary.
