Can you get a shot to boost your immunity?

Patient's question:

Main symptoms: Recurrent colds and fever
Onset time: Physical examination results
Previous treatment history and effectiveness: Severe anemia, malnutrition, stunted growth, can not get anti-body injections, may have dependence, may have interference

Doctor's answer:

High fever is caused by weakened immunity, and poor resistance can be improved by enhancing nutrition, especially protein-rich foods, or through medication, such as taking probiotics. If zinc deficiency is present, it can also lead to weakened immunity in children, and zinc supplementation may be necessary. Children with weakened immunity are prone to fever, and getting vaccinated early during seasonal transitions can help prevent fever, which is also a good decision. Additionally, it is important to actively treat anemia.
