Solution

The correct option is (A) T.B.

BCG vaccine

The BCG vaccination offers a defence against TB, generally known as tuberculosis. Mycobacterium bovis, which is closely related to Mycobacterium tuberculosis, is used to make this vaccine in a weakened form. TB is a dangerous illness that mostly affects the lungs but may also cause damage to the bones, joints, kidneys, brain (meningitis), and other organs.

The BCG vaccination delays the onset of the illness but does not stop an individual from contracting the TB-causing germs. It is made particularly to protect kids against tuberculosis. It may be administered starting at birth and is very successful in avoiding severe TB in newborns. An injection is used to administer the BCG vaccination close under the skin, often on the upper left arm.

Vaccination reactions, often known as vaccine side effects, can happen. The typical response to the BCG vaccine is redness and/or a tiny lump at the injection site, which is followed a few weeks later by a small ulcer (an open sore). The ulcer typically has a diameter of less than a centimetre and may persist for a few weeks to a few months before turning into a thin, flat scar.

Final Answer

BCG vaccine provides protection against T.B.
