When did they give TB vaccinations?

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. Today, the only effective tuberculosis vaccine in common use is the Bacillus Calmette-Guérin (BCG) vaccine, first used on humans in 1921.

Why did the TB vaccine leave a scar?

The vaccine requires multiple punctures giving multiple infection start sites, so it becomes very inflammatory – leaving behind the scar tissue. The TB vaccine is different, in that it is a single injection, but BCG is extremely immunogenic and causes severe local inflammation, which can cause a long-lasting scar.

When was the last case of smallpox in Australia?

Smallpox last appeared in Australia in 1938, and the last naturally occurring case in the world was reported from Somalia in 1977. The virus is now only held officially in two secure laboratories. Any reappearance of smallpox is likely to be the result of bioterrorism, but the risk of this is extremely low.

Does Tuberculosis still exist in Australia?

The incidence of tuberculosis (TB) in Australia (5.3 cases per 100,000 population in 2015) remains amongst the lowest recorded globally. As such Australia together with other countries with a TB incidence of 10 per 100,000 population or less are in a position where TB elimination is feasible by 2050.

Is there a vaccine against tuberculosis?

Bacille Calmette-Guérin (BCG) is a vaccine for tuberculosis (TB) disease.

Can you still get tuberculosis if vaccinated?

You can still get TB infection or TB disease even if you were vaccinated with BCG. You will need a TB test to see if you have latent TB infection or TB disease.

Why is BCG given in left arm?

How long did it take to get a vaccine for tuberculosis?

The vaccine was developed over a period of 13 years, from 1908 to 1921, by French bacteriologists Albert Calmette and Camille Guérin, who named the product Bacillus Calmette-Guérin, or BCG. The vaccine is administered shortly after birth only in infants at high risk of tuberculosis.

Does polio vaccine leave a scar?

As the body repairs the damage, it forms scar tissue. In most people, this scar tissue is small. However, some people experience an inflammatory response to the injection of the vaccine, which can lead to a larger, raised scar.
