Vaccination is a vaccination. Vaccination is an effective means of preventing infectious diseases caused by certain pathogenic microorganisms (such as bacteria, rickettsia, viruses, etc.). Babies cannot receive vaccinations when they are on medication, because vaccination itself may cause fever, rash, discomfort, etc. Babies cannot receive vaccinations when they are not in good condition. So how many days after stopping the medicine can I get the vaccination? Generally speaking, the vaccine can be given only after the child has stopped taking the medicine for 3 days, because after 3 days, the medicine has been completely metabolized in the body and excreted, and the injection will not cause adverse reactions due to drug interactions. The best time to get vaccinated is one week after the medication has been metabolized and the body is back to a healthy state. It should be noted that during the vaccination period, if the child is in discomfort, with symptoms such as vomiting, diarrhea and severe coughing, the vaccination can be temporarily withheld with the consent of the doctor, and the vaccination can be made up when the symptoms improve. Children with asthma, eczema, hives and allergic constitution are prone to allergic reactions after vaccination, especially those with strong allergens such as measles vaccine and mixed vaccines for 100, white and diphtheria. Children with a history of epilepsy and convulsions are prone to fainting, cramps and shock after vaccination, especially the B encephalitis vaccine and the B and B vaccine. Parents need to pay extra attention to the occurrence of allergies in their children when injecting the above-mentioned vaccines. It is important to consult with the doctor before the vaccination. Sometimes, even after stopping medication for three days, the disease may not necessarily be cured and the vaccination may not be suitable.
