Tuberculosis (TB) vaccines are vaccinations intended for the prevention of tuberculosis. Immunotherapy as a defence against TB was first proposed in 1890 by Robert Koch . [ 1 ] As of 2021, the only effective tuberculosis vaccine in common use is the Bacillus Calmette-Guérin (BCG) vaccine, first used on humans in 1921.
The tuberculosis outbreak in Kansas has many people wondering if there is a vaccine for TB in the U.S. Here's what doctors want you to know about prevention.
M72/AS01 E is an experimental tuberculosis vaccine. If approved, it would be the first vaccine for tuberculosis in more than a century after the BCG vaccine. [1] [2] The vaccine consists of two main ingredients. The antigen part is M72, a recombinant fusion protein derived from the sequences of two M. tuberculosis antigens (Mtb32A and Mtb39A ).
The Bacillus Calmette–Guérin (BCG) vaccine is a vaccine primarily used against tuberculosis (TB). [9] It is named after its inventors Albert Calmette and Camille Guérin. [10] [11] In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as soon after birth as possible. [9]
This is a timeline of the development of prophylactic human vaccines. Early vaccines may be listed by the first year of development or testing, but later entries usually show the year the vaccine finished trials and became available on the market. Although vaccines exist for the diseases listed below, only smallpox has
In primary TB disease (some 1–5% of cases), this occurs soon after the initial infection. [13] However, in the majority of cases, a latent infection occurs with no obvious symptoms. [13] These dormant bacilli produce active tuberculosis in 5–10% of these latent cases, often many years after infection. [48]
In fact, "it isn't easy to catch TB. You need consistent exposure to the contagious person for a long time. For that reason, you're more likely to catch TB from a relative than a stranger." [7] If a person had latent tuberculosis, they do not have active/contagious tuberculosis. Once exposed, people very often have latent tuberculosis.
