The vaccine is 70 to 80% effective against the most severe forms of TB, such as TB meningitis in children. It’s less effective in preventing respiratory disease, which is the more common form of TB in adults.
Does everyone get a BCG scar?

Why did old vaccinations leave a scar?
Why did scarring occur? Scars like the smallpox vaccine scar form due to the body’s natural healing process. When the skin is injured (like it is with the smallpox vaccine), the body rapidly responds to repair the tissue.
What happens if BCG does not work?
BCG failure is also associated with an approximately 50 percent chance of disease progression and poor prognosis. Radical cystectomy is the standard treatment when intravesical BCG therapy fails.
Why is BCG given in left arm?
The vaccine is given just under the skin (intradermally), usually in the left upper arm. This is the recommended site, so that small scar left after vaccination can be easily found in the future as evidence of previous vaccination.
What vaccine was given with a gun?

The vaccine does not always prevent disease. It is more effective in children < 6yrs old, providing 50 to 80 % protection against meningeal and miliary TB. Protection against TB will only start 6-8 weeks after the vaccination has been given and lasts for about 10 years.
What if scar is not seen after BCG vaccination?
While it is correct to ‘assume’ failed BCG vaccination if no scar is seen 90 days after inoculation, it does not necessarily mean that it had actually failed to induce some immune response that can be proved by laboratory tests.
Is it normal for BCG vaccine to have pus?
There are some rare side effects associated with the BCG vaccine. If any of the following occur, see your GP: A large abscess (collection of pus) at the injection site. Tenderness and swelling under the left arm – this could indicate an infection of the glands (called the axillary lymph nodes).

Why does the BCG injection leave a scar?
The BCG vaccine is given just under the skin. Two to four weeks later, a pustule occurs at the site. The pustule might open and drain. The size of the scar depends on the amount of inflammation caused by the person’s immune response and the person’s healing ability.
