What vaccinations should be given at the age of four?

In our country, there are many vaccinations specifically for infants and young children, and the injections are not given randomly, but in stages and by age. It may take several years to complete the injections, so all parents and friends who are about to become parents in the future must make it clear. When the baby reaches 4 years old, vaccinations cannot be stopped. So what vaccinations should be given to the baby at the age of four?

Baby vaccination at 4 years old

Planned vaccines (Class I vaccines) are included in the national immunization program. They are free vaccines and must be administered to babies from birth. The vaccines that 4-year-old babies need to be given include: polio vaccine (boosted), to ensure that the baby does not contract polio.

Polio vaccine (boost): Babies need to be given polio vaccine at the age of 4. Polio vaccine, also known as polio vaccine, is a vaccine used to prevent polio. The live attenuated polio vaccine currently being used in my country is also known as the "sugar pill", which is made of live viruses with reduced pathogenicity.

Things to note when your baby gets polio vaccine at 4 years old

1. Mild gastrointestinal symptoms such as fever, headache, diarrhea, and occasional rash may occur, which usually heal on their own after 2-3 days. A very rare serious adverse reaction is vaccine-related paralysis.

2. Avoid strenuous activities within two to three days after the injection and pay attention to the cleanliness of the injection site. Do not take a bath for the time being to prevent local infection.

3. If vomiting occurs while taking the "sugar pill", you should take it again. It is best to delay use if you suffer from gastrointestinal diseases.

4. The polio vaccine is in the form of sugar pills or liquids. It is afraid of heat and will become ineffective when exposed to heat. Therefore, do not take the medicine with hot water. When taking the medicine, first crush the sugar pill with a spoon or chopsticks, or dissolve the sugar pill in cold boiled water (do not use hot boiled water) with a spoon and take it.

5. It is best to stop breastfeeding within half an hour after taking the vaccine (you can use milk or other milk substitutes), otherwise the antibodies in the breast milk will neutralize (kill) the vaccine and affect its effectiveness.
