Signs and pictures of successful BCG vaccination, and how to see whether BCG vaccination is successful or not.

Many babies will have adverse reactions after BCG vaccination, mainly because this vaccine is an attenuated live vaccine, which will cause some discomfort to the vaccinated baby under the immune function, such as local redness, swelling, pain, fever, drowsiness, crying and so on. The state encourages all newborn babies to be vaccinated with BCG. Come with me to understand the signs and pictures of successful BCG vaccination, and what do you think of the success of BCG vaccination?

Although the success rate of BCG vaccination is about 95%, there are also some babies who have no antibodies in their bodies after vaccination. Through local reaction observation, we can initially know whether BCG vaccination is successful. Generally, after inoculation, it will appear red and swollen at 1-2 weeks or 3-4 weeks after BCG inoculation, and the local red and swollen diameter is generally around 5- 10 mm, which is a normal phenomenon of successful BCG inoculation. If the inoculation site does not leave local redness and scars, it is necessary to pay attention to the fact that BCG is not inoculated. After examination, there is no antibody in the child's body and it needs to be replanted.

Usually, babies who are successfully vaccinated with BCG will have scars, but some babies have obvious scars and some are very light in color. The scar left by BCG, as shown above, shows that the body has an immune response to the vaccine, and the vaccinated children have antibodies in their bodies, suggesting that BCG vaccination was successful. However, the fact that the baby has been vaccinated with BCG without scars does not mean that the vaccination is unsuccessful. At this time, you can go to the hospital to do a PPD test to determine whether you have been vaccinated with BCG.
