Tuberculosis Vaccine; Intended for the Prevention against Tuberculosis (Tb) Infection
Tuberculosis Vaccine |
Tuberculosis
Vaccine, such as Bacillus Calmette-Guerin (BCG) vaccine, is used for tuberculosis
(TB). Tuberculosis (TB) is a highly contagious disease caused by a bacteria
called Mycobacterium tuberculosis and is spread through person to person
contact. The bacteria spread when an infected person sneezes or coughs.
Tuberculosis mainly affects the lungs and might lead to the death. Two types of
TB are commonly observed, such as latent TB and active TB. In latent TB, the
infected person does not show symptoms, while in active TB, infected person
shows clinical symptoms.
Clinical symptoms of TB include shortness of breath, chest
pain, fatigue, hemoptysis, weight loss, cough, night sweats, and fever. Tuberculosis
can be diagnosed with the help of interferon-gamma release assays, polymerase
chain reaction tests, or skin tests. Tuberculosis is highly endemic in Mexico,
especially among the native Indian populations in southern Mexico and Baja
California. Mexico is on the top five countries with the highest number of TB
cases in America continent. Thus, there is an increase in demand for tuberculosis vaccine in Mexico.
Bacille Calmette-Guérin (BCG) is one of the most widely
administered vaccines across the globe. It is often given to infants and small
children in countries where TB is common. Children aged between 1 and 16 years
who should have the BCG vaccine. BCG vaccination is recommended for all older
children and adults at risk of TB. BCG vaccination is also recommended for
people aged 16 years to 35 years who are at occupational risk of Tuberculosis
exposure, such as
healthcare or laboratory workers who have direct contact with TB patient or with
clinical samples and materials.
Tuberculosis
Vaccine,
such as BCG, triggers the immune
system to protect against the infection. It provides consistent protection against
the most severe forms of TB. BCG is only licensed vaccine for prevention of tuberculosis
(TB) disease, and has been recommended at birth in countries with a high
tuberculosis burden for decades.
