More than one scientific study has been published that talks about the role of vaccinations - especially against tuberculosis - in reducing infection with the emerging coronavirus (SARS Cove 2), which causes Covid-19 disease.

The outbreak of the Corona virus began in Wuhan, China, last December in a food market that was selling wild animals illegally. The number of infections worldwide exceeded one million and a quarter million, seventy thousand deaths, and the number is on the rise.

The virus was called SARS-CoV-2, to distinguish it from the SARS-CoV virus, which causes severe acute respiratory syndrome (SARS), which spread in 2002-2003, and caused 774 Deaths, mostly in Asia.

One of those studies was published on medRxiv for unpublished medical research, and showed that countries that give their citizens vaccinations such as BCG vaccination showed fewer confirmed cases of infection or death from the Coronavirus.

The study also indicated that about six countries around the world are currently vaccinating first-class doctors to combat the Corona virus with a BCG vaccine, in addition to vaccinating a number of elderly people, and studying the extent of protection that they can get against infection with the Corona virus as a result.

According to Dr. Gonzalo Otazu, associate professor at the New York Institute of Technology and lead author of the study, he noted the low number of HIV infections in Japan, which was one of the first countries to report a pandemic.Japan has adopted a compulsory vaccination policy, which is the same in South Korea, which has succeeded in curbing the spread of the virus.

Reducing injuries and deaths

In the new study, researchers looked at 15 days of HIV infection and deaths between March 9 and 24 in 178 countries,The study concluded that "Covid-19 incidence was an average of 38 cases per million people in countries with BCG vaccination, compared to about 358 cases per million when there was no national vaccination program,While the death rate was 4.28 / per million people in countries with BCG vaccination programs compared to 40 / per million people in countries without such a program".

On the other hand, countries like Iran - which adopted a national program to vaccinate children against tuberculosis, but very late - were one of the most affected countries in the world by the Corona virus.

The study indicates that Japan and South Korea have mandatory BCG vaccine policies, and have managed to control the spread of the virus with a high degree.

Dr. Ashish Kamat, co-author of the paper and professor of oncology and cancer research at MD Anderson Cancer Center in Houston, says;"While we were expecting to see a preventive effect of BCG vaccination, the magnitude of the difference reached about ten times between HIV infections and deaths between countries without the BCG vaccination program and those with a vaccine program."

According to Bloomberg, the Dutch doctors at Radboud Universty University Center were among the first to test the effectiveness of the BCG vaccine against the emerging coronavirus, where they studied the response of four hundred health workers,In a scientific experiment, two hundred of them received a BCG vaccine, and two hundred received a placebo, but it is not expected that any study results will appear at least two months ago.

The Dutch researchers team also intends to start a separate experiment to study the effectiveness of the BCG vaccine for those over the age of sixty years, and other experiments are being conducted in Australia, Denmark, Germany, the United Kingdom and the United States,While studies are underway to understand why the BCG vaccine is effective not only against tuberculosis, but against other microbes.

The Dutch team says that the BCG vaccine strengthens the immune system in a way that makes it ready to respond better to the microbes that adopt the TB bacteria strategy to attack the human body.
