What happened to the swollen needles after the child s vaccination?

1. Swelling and pain at the vaccination site is a normal reaction In fact, for this kind of ** symptom, parents should not be too nervous, after vaccination, the pain, tenderness, redness and swelling at the injection site are common adverse reactions of the vaccine, which is not caused by the quality of the vaccine. We need to know this common sense, that is, adverse reactions refer to reactions that occur in the correct dosage and use that are not related to medication.

2. Severe abscess reactions require hospital treatment for most vaccines. Generally, it lasts for 1-2 days and resolves on its own, and no treatment is required. Some children may have induration at the vaccination site, which can be absorbed by themselves in 1-2 months.

There are also a very small number of children, there will be local aseptic suppuration, this situation needs to be used a syringe to repeatedly draw out the pus, severe ulceration, need to expand the necrotic tissue, the disease is longer, but finally can be absorbed and healed.

3. Give a representative example, such as for BCG. As mentioned in the question, I guess the swelling should be the BCG vaccination, because most children will experience swelling with this vaccine. For children who receive this vaccine, there will usually be local redness, swelling and infiltration about 2 weeks after the injection, followed by suppuration and the formation of small ulcers.

The Chinese National Formulary Children's Edition, in the BCG chapter, mentions that the treatment of adverse reactions is recommended according to the specific situation of ulceration, if it is severe, it can be smeared with 1% methyl violet solution to prevent infection, generally 8-12 weeks later, it can be scabbed, if it is regional lymphadenopathy swelling and softening to form pustules, it should be diagnosed and treated in a timely hospital.

The advice of the Hong Kong Department of Health is that small red pimples or sores may appear at the site of vaccination, but they will gradually recede and heal after a few weeks, leaving minimal or no scarring. Occasionally, some children will have swollen underarm swelling due to swollen lymph glands. If there is pus filling or small ulcers, it is also normal, and parents do not need to worry.

The Hong Kong Department of Health also said that babies can shower as usual, as long as the vaccination site is clean and dry, clean with frozen boiled water if necessary, and use gauze to absorb the water. Do not apply any medications, syrups, or ointments to the inoculation site. There is no need to apply adhesive tape or bandage, and avoid tight clothing.

4. Personal opinionTherefore, if the child is unwell, we can't make the popular science suggestions too dead, and we must deal with it according to the actual situation of the child. The advice of the Hong Kong Department of Health is for most children, and a small number of children may develop serious secondary bacterial infections after scratching because they do not follow such requirements, but don't worry, they will need to be treated in a general surgery clinic if necessary.

During the vaccination process, due to the different types of vaccines, local discomfort such as redness, swelling, and induration may occur after vaccination, and some children may also have systemic symptoms such as low-grade fever and fatigue, which are common adverse reactions after vaccination.

Hello, the situation you mentioned is usually an adverse reaction to vaccination, usually about 24 hours after vaccination, there is redness, high swelling, heat and pain at the vaccination site.

According to the size of redness or infiltration, it is divided into weak good ruler reaction (diameter of less than centimeter), medium reaction (diameter of centimeter) and strong reaction (diameter of more than 5 cm or diameter of less than 5 cm but accompanied by lymphadenitis). For example, after diphtheria-tetanus-pertussis triple vaccination, about 5% to 10% of children have obvious redness, swelling, hard lumps or pain at the injection site.

At present, there is no way to prevent this vaccine, but to take good care of the child and make the child a little smaller.

Problem analysis: Hello, this kind of love search is mostly caused by poor absorption of vaccines, mostly due to the lack of shaking and searching when injecting the vaccine or the injection site is too shallow.

Suggestions: Some vaccines are process problems, and there will be more impurities, which will also lead to this situation. A warm compress can be applied with a towel several times a day. Watch your child for a fever.
