Why is the TB vaccine not given in the US?

Does BCG always leave a scar?
BCG vaccination scar It’s important to leave the area uncovered as the air will help it to heal. It’s normal for it to leave a small scar. Occasionally, there may be a more severe skin reaction, but this should heal within several weeks.

Does BCG vaccine last for life?
The BCG vaccination is thought to protect up to 80% of people against the most severe forms of TB for at least 15 years, perhaps even up to 60 years.
Do they still give the smallpox vaccine?
The smallpox vaccine is no longer available to the public. In 1972, routine smallpox vaccination in the United States ended. In 1980, the World Health Organization (WHO) declared smallpox was eliminated. Because of this, the public doesn’t need protection from the disease.
What happens if BCG is not given?

What if scar is not seen after BCG vaccination?
While it is correct to ‘assume’ failed BCG vaccination if no scar is seen 90 days after inoculation, it does not necessarily mean that it had actually failed to induce some immune response that can be proved by laboratory tests.
How do you get rid of BCG scars?
Researchers from the National Skin Centre (NSC) have developed a near-painless, micro-needle patch to shrink these blemishes, which are called keloid scars. The patch will offer patients an alternative to a monthly injection into the scar, which is currently the most effective form of treatment but is often painful.
What is the scar on older people’s arm?
