What is BCG Vaccine?
Bacillus Calmette-Guérin (BCG) is a vaccine developed almost a century ago to protect against tuberculosis (TB). TB is a bacterial infection that primarily affects the lungs but can spread to other organs. TB is spread through the air when an infected person coughs or sneezes, releasing bacteria into the air. People who are exposed to these bacteria may become infected, and if the infection is not treated, it can lead to serious health problems. The BCG vaccine is given to infants and children to help protect them from TB. It is a live vaccine, which means that it contains a weakened form of the TB bacteria. This weakened bacteria can't cause TB, but it can help the body's immune system learn to recognize and fight TB infection.

Why Does BCG Vaccine Leave a Scar?
The BCG vaccine is given as a single injection, typically in the upper arm. The injection site will usually become red and swollen within a few days, and a small blister may form. The blister will eventually crust over and then fall off, leaving a small scar. This scar is a normal reaction to the vaccine and is a sign that the body's immune system is responding to the vaccine. The scar is usually small and fades over time, but it may be visible for several years.

What is the Purpose of the Scar?
The scar left by the BCG vaccine serves as a permanent reminder that the person has been vaccinated against TB. This is important because TB is a serious disease that can be fatal if not treated. The scar also helps healthcare providers to identify people who have been vaccinated against TB, which can be helpful in tracking and controlling the spread of the disease.

Is the Scar a Sign of Infection?
No, the scar left by the BCG vaccine is not a sign of infection. It is a normal reaction to the vaccine and is a sign that the body's immune system is responding to the vaccine. The scar is usually small and fades over time, but it may be visible for several years. If you are concerned about the scar, you should talk to your doctor.

Is the Scar a Cause for Concern?
In most cases, the scar left by the BCG vaccine is not a cause for concern. However, in some cases, the scar may become infected. Signs of an infected scar include redness, swelling, pain, and drainage. If you think your BCG scar is infected, you should see a doctor right away.
