The patient with allergic purpura is not unable to take vaccine for life, it needs to be analyzed according to the patient’s own constitution and condition. If the patient is in the acute phase of allergic purpura, vaccination is generally not recommended, if the patient is in the recovery phase of allergic purpura or has been cured, most of the vaccines can be played normally. 1. acute phase of allergic purpura: allergic purpura is a common vascular metaplasia disease, in the acute phase of allergic purpura, the patient may have abnormal immune function, and vaccines usually act on patient’s immune system, an immune response occurs, and antibodies are produced. If the vaccine is given during the acute phase of allergic purpura, it may aggravate the patient’s condition or make the vaccine less effective or ineffective, and may even cause other adverse reactions in the patient, so it is usually not recommended to be vaccinated; 2. Recovery period of allergic purpura: Patients recovering from allergic purpura are gradually returning to normal immune function as the disease is in remission, and some of the vaccines can be played at this time. However, patients in the recovery period of allergic purpura may still need to take some medications, which may not be suitable for use with the vaccine at the same time, so it is recommended to consult the doctor in advance whether you need to stop the medication before vaccination. If the patient has been cured of allergic purpura and there is no recurrence, the vaccine can usually be given and it usually will not affect the organism or the vaccine effect. However, patients with a history of allergic purpura are mostly allergic, so it is recommended to consult the vaccine components and confirm that there is no allergy before vaccination. In addition, because contraindications to vaccination vary from place to place, it is recommended that patients with allergic purpura consult with the relevant medical institutions about whether they can have the vaccine before having it.
