Australian researchers demonstrate how children’s immunity evolves immediately after BCG vaccination, providing protection against germs other than tuberculosis.
- BCG vaccination is no longer mandatory, just recommended in France since 2007.
- The coverage rate is now 58% according to figures from Public Health France.
A vaccine with multiple benefits! According to an Australian study published in Sciencethe BCG vaccine would protect well beyond tuberculosis.
“Live” vaccines
This is information that has been known for more than a century but whose mechanism was still unknown, and this study is a game-changer.
According to the researchers, when two different strains of BCG are inoculated in vitro in the laboratory, they modify the DNA of white blood cells for 14 months, but in addition, these strains modify the bone marrow which itself will generate future white blood cells, which protect against other viruses, bacteria and fungi.
This protection is observed with all the vaccines known as “living“, inoculated with the still active virus like the vaccine against poliomyelitis in its version”drinkable“, or the measles-mumps-rubella vaccine.
Beneficial side effects
As reported France Newsat the Pasteur Institute in Lille, Professor Camille Locht, director of research at the National Institute of Health and Medical Research (INSERM) is developing a new vaccine, also living, against whooping cough and which would protect against asthma, according to his observations on vaccinated rats.
This question of vaccines with beneficial side effects raises fears of stopping the marketing of certain vaccines, which could cause a resumption of mortality among children. This is particularly the case of the drinkable polio vaccine which will soon be withdrawn from the market and of the BCG vaccine, the production of which has been abandoned by the last French producer, Sanofi.
“Reduce the number of cases”
Regarding the BCG vaccine in particular, a the study of the academy of sciences (PNAS) – American-British team – had concluded that he “could have reduced the number of Covid cases, hospitalizations and mortality during the winter of 2020 in the United States“. Indeed, during a test in the United States on the possible effect “positive” of this diabetes vaccine, there were no cases of Covid in the group which had received three doses of BCG, unlike the unvaccinated group.
