Why do you have to get a TB shot?

Answer 1

Immunization to the disease

The vaccine is said to work in 40% of people given it

It saves money as the cost to treat a person with it is higher than the cost of giving a person a vaccination to help prevent them from catching the disease.

It would be worth giving the vaccine to homeless people and other groups that are at risk of getting the disease, as it is pretty cheap and otherwise could kill the person so it may save lives.

Answer 2

TB can present in different parts of the body and symptoms can include swollen glands in your neck, joint pain or a headache. Serious damage to the human body can be caused through undiagnosed, delayed, or untreated tuberculosis. TB can affect the central nervous system, cause brain damage, circulatory system damage, skin, lymph nodes, joints, bones and intestines. TB can also cause permanent lung damage.

The number of cases of T.B is on the rise and here are some facts on that.

Currently 1.7 million people die of tuberculosis globally each year.

Incidence in the UK has gradually increased over the past 15 years, with more than 9,000 cases reported in 2011, a rate of 14.6 per 100,000 population. This is said to contrast with a general decline seen in other western European countries, with the UK being the only European country where TB rates continue to rise.

In London, the number of cases has risen by almost 50% since 1999, up from 2,309 in 1999 to 3,450 in 2011. London now accounts for almost 40% of all TB cases in the UK.

The increase in the number of tuberculosis cases in the UK has largely been in non-UK born groups. In 2009, these included black African (28%), Indian (27%), and white people (10%). However, 85% of individuals born overseas had lived in the UK for at least two years prior to being diagnosed, i.e. they were not recent immigrants. This suggests transmission may have occurred after they had arrived in the UK.

You might ask how the vaccine may work and so the vaccine is called a BCG vaccine contains a strain of mycobacterium bovis, which is a bacterium that causes tuberculosis in cattle. The bacteria have been altered so that they do not cause a TB infection but make your immune system produce protection. This makes you immune (resistant) to the disease.
