Children should not eat shrimp after vaccination, because after vaccination there will be side effects, such as redness and swelling of the injection site and pus, and some children will have fever symptoms after vaccination. Even though shrimp is rich in nutrients, it is also a food that is particularly susceptible to allergies, and this particular case of vaccination can easily trigger an allergic reaction in the child’s body, which may lead to increased redness, swelling, and pus at the injection site, and possibly infection. If the child has a fever, it may lead to a higher temperature or cause other complications such as coughing and wheezing, so shrimp should not be eaten after the vaccination.
