What to do if swelling occurs after vaccination

I believe many people have had the experience of getting vaccinated. Many times people get vaccinated mainly to prevent a certain disease. Especially for some young children, more vaccines are given in the early stages. I believe that everyone who has been vaccinated knows that there is no physical reaction after the vaccination. However, some people found that their bodies were swollen after getting the vaccine. When this happens, many people don't know the specific reason. Not to mention what methods to use to solve it. So what should I do if I get swollen after vaccination?

Tools/Raw Materials

Shimizu

Cotton swab or tweezers with disinfectant cloth

Methods/Steps

Pay special attention to any redness or swelling of the skin at the injection site. If the redness and swelling at the vaccination site is small and mild, and can subside within a few days, it means that the inflammatory response is quickly controlled and will not cause harm, and parents do not need to worry; if the redness and swelling is widespread and more severe, you should go to the hospital for treatment, but tell the doctor the type of vaccine and the time of vaccination before seeing the doctor.

Except for BCG, no pus-like changes will occur at the injection site of other vaccines. 2-4 weeks after BCG vaccination, the injection site will begin to become red, swollen, fester, ulcerate, and scab, and finally leave small scars. The whole process lasts 2-4 months. Ulceration and pus discharge are common reactions after BCG vaccination. To care for the wound, just wipe it with clean water and then dry it. Using iodine or alcohol for local disinfection will make the wound difficult to heal. Parents must pay attention to this.

Treatment can be based on the cause of the swelling:

(1) Before using large-molecule vaccines such as diphtheria, pertussis and tetanus vaccines, the vaccine must be fully warmed up and the solution must be fully shaken before aspirating to minimize the chance of swelling;

(2) For children who have difficulty absorbing vaccine components, local swelling reduction treatment can be performed;

(3) For some infections caused by scratching or getting wet, the affected area can be disinfected and then the swelling can be reduced locally;

(4) Swelling caused by allergies can be treated with anti-allergic drugs, and the swelling can gradually subside;

Several simple methods for local swelling reduction;

(1) Cold and hot compresses; first cold compress and then hot compress. Considering the treatment of various types of swelling, some vaccines require hot compresses at the beginning, and the temperature must be strictly controlled when using cold and hot compresses. Children's skin is delicate and easily burned (generally not recommended)

(2) Apply potato slices locally; potatoes have the effect of astringing and reducing swelling and are relatively simple to use. Cut raw potatoes into thin slices, dig out the needle hole, and apply the slices locally; (recommended)

(3) Others: anti-allergic treatment, subsequent magnesium sulfate wet compress, etc.

Precautions

The vaccination site must be kept clean and the injection site does not need to be covered. If the vaccination site is covered with a Band-Aid or other material, it must be removed after two hours.
