- BCG, or bacilleCalmette-Guerin, is a vaccine for tuberculosis (TB) disease.
- The BCG vaccine is known to confer a strong immune response and a significant degree of protection against leprosy and non-invasive bladder cancers.
- According to a recent study those countries where the elderly were likely to have had a BCG shot in their childhood were likely to be better protected against coronavirus.
- Because COVID-19 was particularly lethal to the elderly people.
- Countries like Spain, France, the United States, Italy and the Netherlands don’t have universal BCG policies and have seen many deaths from COVID-19.
- Italy, where the COVID-19 mortality is very high, never implemented universal BCG vaccination.
- It is reported that India has a consistent TB vaccination policy since 1948
- Japan has a BCG policy since 1947.
- It had one of the early cases of COVID-19 but it has maintained a low mortality rate despite not implementing the strictest forms of social isolation.
- Iran began implementing its BCG vaccination policy only in 1984 and therefore anyone over 36 was vulnerable.
