Why does redness and swelling occur after receiving the pentavalent vaccine?

Vaccines are very important medicines in life. People use vaccinations to allow the body to produce corresponding antibodies to prevent some malignant diseases. This method is very effective, and the antibodies produced after vaccination can last a lifetime. However, some vaccines may cause adverse reactions to the body.

A pentavalent vaccine is a vaccine containing five live, inactivated organisms or purified antigens, jointly formulated by producers for the prevention of multiple diseases or diseases caused by different species or serotypes of the same organism.

Local skin redness and swelling may occur after receiving the pentavalent vaccine. This is a normal reaction caused by normal stimulation. Some children may also have fever. Just drink more water. For local redness and swelling, you can apply potato slices and change them every 4-6 hours. Pay attention to local hygiene to prevent infection.

If it does not gradually worsen, it can be considered normal. Pay attention and observe. You can apply local heat. Most cases require 3 to 5 days for the swelling to subside. If the condition gradually worsens and is accompanied by cyanosis, it is recommended to go to the hospital for examination in time.
