We have written here before that existing vaccines, such as the TB vaccine, can improve the body's immune response against corona, and now a new Israeli study gives another reason for optimism in this regard.
The study, conducted at Ben-Gurion University and the Hebrew University, strengthens the link between the Bacillus Calmette-Guerin BCG tuberculosis vaccine and Corona virus protection.
The researchers found that tuberculosis vaccines given over the past 15 years may provide protection against coronary heart disease in people under the age of 24. The findings were recently published in the journal Vaccines.

This is what it takes to really stop the corona plague
To the full article
The findings of the current study join a number of clinical trials and trials conducted around the world since the outbreak of the plague in order to test whether a tuberculosis vaccine may help against the corona virus and reduce the risk of infection.
The tuberculosis vaccine is based on live-attenuated bacteria of the cows' tuberculosis.
The vaccine causes the body to produce antibodies against tuberculosis bacteria and thus prevents the infection and its complications.
Today, the tuberculosis vaccine is still widely available, but in various countries, most of which have developed, vaccination has been stopped in recent years due to the small number of cases of the disease.
In Israel, too, they stopped vaccinating against tuberculosis several years ago.

Dr. Nadav Rapoport, from the Department of Software and Information Systems Engineering at Ben-Gurion University of the Negev, and colleagues from the Hebrew University Daniel Klinger, Ido Blass and Prof. Michal Liniel analyzed the relationship between the degree of vaccination of the population against tuberculosis in the country and the effect of corona on the population. several patients is difficult and mortality rates. They found the young population under the age of 24 received the vaccine in the past 15 years has been more protected from the virus beams, thereby reducing infection rates and mortality rates due to infection. There was no effect among adults who were vaccinated years ago.
study , Dr. Rapoport and colleagues analyzed data from 55 countries around the world, which make up 62.9 percent of the world population.
To normalize the data, they included countries with a population of more than 3 million people.
Because the corona plague broke out in different countries at different times, they took into account data by the first date the country reached the mortality rate of one person for every 2 million people.
In addition, various demographic and economic variables that characterize each country such as the number of hospital beds per capita and GDP were neutralized.
Adults did not have the same effect.

The results showed a negative correlation between the number of vaccine years given in the country and the mortality rates from the virus, and the number of serious patients reported in the country.
That is, the more years the vaccine is given, the fewer patients and deaths from Corona in the country relative to the size of the population.
It should be noted that to test whether other vaccines also affected corona virus outcomes, they performed the same analysis regarding measles and mumps vaccines, and no statistically significant association was found for corona protection.
"Comparing countries and segmenting the findings by age revealed that the protective effect of the vaccine was most significant among those aged 24 and under," said Dr. Rapoport. "We assume the vaccine provides protection for a certain period of time and probably Dr. Rapoport added that "the findings suggest the need to examine tuberculosis vaccination protocols in the context of the current epidemic, which may help develop a rapid vaccine against corona."
