Reaction after BCG vaccination

In fact, getting various vaccines is an issue that must be taken seriously during a child's growth process. It is also a way to help them stay healthy. Especially now that people are paying more and more attention to children's growth, these vaccine issues must be taken seriously. So do you know what are the normal reactions of children after vaccination? Let’s take a detailed look at the reactions after vaccination.

Vaccination is actually to better help babies maintain health and prevent the invasion of certain diseases. Therefore, parents must not ignore this issue. They must not ignore what kind of vaccines children should get at any time.

BCG vaccination generally has no systemic reaction. In a few people, the axillary lymph nodes on the vaccination side (a few are supraclavicular or contralateral axillary lymph nodes) may be slightly swollen within 1 to 3 months after vaccination, but the size does not exceed 10 mm. Sometimes ulceration and suppuration may occur. This is a normal reaction. As the vaccination site heals, the swollen lymph nodes will subside on their own. Pustules and ulcers that are larger than 10 mm in diameter and take more than 12 weeks to heal are called exacerbated reactions or severe reactions.

Guidance:

In recent years, due to the great improvement in the quality of BCG and vaccination technology, the aggravated reactions caused by vaccination, especially lymph node suppuration, have been significantly reduced. The occurrence of strong reactions is related to vaccine activity, injection dose, injection technique, injection site, secondary infection and individual factors.

Normal reactions can be relieved by hot compresses. If an abscess is formed, you can ask the doctor to extract the pus with a syringe to promote healing. It generally does not affect the child's health.

If you want your children to grow up healthy and happy and avoid various adverse injuries, then these vaccinations must be taken seriously. Only in this way can you provide more barrier protection for your children's health, allowing them to avoid being affected by some adverse factors and allowing them to grow up more healthily and happily.
