How long should I be observed after vaccination?

I believe that parents who have given their babies vaccinations know that babies need to be observed at the injection site for a period of time after the vaccination. Many parents do not understand why this is necessary. In fact, observation after the vaccination is a very important thing. It can be used to observe whether the baby has any adverse reactions after the vaccination to prevent harm to the baby. So how long should you observe after getting a vaccination? Let me explain below.

After receiving the vaccination, you need to stay in the vaccination clinic for 30 minutes for observation. This is to prevent the extremely small probability of a life-threatening allergy.

As we all know, penicillin allergy causes anaphylactic shock. If rescued, nothing will happen and there will be no sequelae, but if rescue is not timely, the person may lose his life. This situation is also feared when getting vaccinated, but the occurrence rate of this situation is one in a million, which is a very low probability. This anaphylactic shock reaction usually occurs within 30 minutes after vaccination, and 10% occurs beyond 30 minutes.

What are the adverse reactions after vaccination?

1. General reaction

In most cases, babies will experience inflammatory reactions such as fever, runny nose, dizziness, headache, diarrhea, abdominal distension, loss of appetite, redness and swelling at the injection site, pain or nodules after vaccination. These are general reactions of transient physiological dysfunction. Such reactions often do not require special treatment and usually recover on their own within 2 to 3 days.

2. Abnormal reaction

Due to individual differences, such as those with allergic constitutions, a very small number of babies may experience reactions that are different in nature and manifestation from the general reactions after receiving certain vaccines, such as aseptic suppuration, rash, facial edema, anaphylactic shock and other allergic reactions. These are abnormal reactions.

3. Coincidence

In fact, its occurrence has nothing to do with the vaccine itself. Coincidence refers to the situation where the baby is in the incubation period of a certain disease after vaccination, or has an underlying disease that has not yet been discovered, and the disease coincidentally occurs after vaccination.
