4 countries begin testing a 100-year-old vaccine that may allow treatment and avoid infection with corona


Researchers from 4 countries are preparing to start clinical trials to confirm a vaccine against tuberculosis, which is about 100 years old, to avoid infection with the virus “Covid 19”. According to a report by “Science Mag”, the vaccine used against tuberculosis, which is a bacterial disease, may be able to significantly enhance human immunity until it is able to fight corona “Covid 19”, or it may prevent infection again.

According to “Russia Today”, experimental doses of the vaccine will be provided to doctors and nurses, who are considered more susceptible to respiratory diseases than the general public, as well as the elderly who make up most of the infected and the victims.

A team in the Netherlands will start the first test this week. He will recruit 1,000 healthcare workers in 8 Dutch hospitals, who will receive the BCG vaccine.

BCG contains a weak live strain of Mycobacterium bovis, a bacterium that follows the genus Mycobacterium and causes tuberculosis.

The vaccine is given to children in the first year of their lives in most countries of the world, and it is safe and cheap, and it prevents about 60% of TB cases among children on average, with great differences between countries.

Vaccines generally raise immune responses to target pathogens, such as antibodies that bind one type of virus.
