However, its still given to babies and young children in many countries worldwide.
It was in wide use in parts of Europe, like France and Germany, by the 1920s.
In the resulting 1931 trial, physicians George Deycke and Ernst Altstadt were found guilty of negligent manslaughter.

It spread to more European countries in the 1940s and 1950s, including Great Britain.
Modern Guidelines
The tuberculosis vaccine is no longer routinely administered in the United States.
Studies have shown mixed results in terms of the vaccines effectiveness.
Globally, around 23 million people die from TB disease and related complications yearly.
Age Recommendations
The BCG vaccine is most effective in babies and children under 5.
Older children and adults may not benefit as much from receiving it.
However, people of all ages may still be considered for the vaccine if they have certain risk factors.
In areas where the BCG vaccine is routinely administered, its usually given to newborns.
How Effective Is the Tuberculosis Vaccine in Children Ages 5 and Up?
Symptoms
Tuberculosis is an infection sparked by the bacteriumMycobacterium tuberculosis.Usually,M.
Other symptoms of TB may include:
In some cases,M.
This is known as latent TB infection (LTBI).
People with LBTI cant spread TB to others.
However, about 5% to 10% of people with LTBI develop active TB.
People with TB disease have symptoms and can spreadM.
If left untreated, TB can be serious and even fatal.
Tuberculosis is especially dangerous for immunocompromised people, including people withhuman immunodeficiency virus(HIV).
Cases in the U.S.
In the United States, tuberculosis cases are relatively rare.
In total, 8,300 TB cases were reported to the CDCs National Tuberculosis Surveillance System in 2022.
Rates of TB disease in the United States decreased consistently from 19932019.
Still, the overall number of U.S. TB cases in 2022 was lower than in 2019.
Do They Still Give Tuberculosis Vaccines?
The TB shot is not given routinely in the United States.
A nearby TB control program may also offer vaccination.
Efficacy and Side Effects
Evidence of the effectiveness of the tuberculosis vaccine is somewhat mixed.
Typically, the vaccine is given as a shot in the upper arm to infants just after birth.
The tuberculosis vaccine is safe, but evidence of its effectiveness in protecting against TB is relatively mixed.
The BCG vaccine is no longer widely used in the United States.
Examples include healthcare workers and children who are regularly cared for by adults with drug-resistant tuberculosis or untreated TB.
