A "century-old" vaccine may protect humans from corona
Researchers from four countries are preparing to initiate clinical attempts to ensure that a hundred-year-old vaccine against tuberculosis can be effective in preventing Corona virus "Covid 19".
According to the journal "Science", the vaccine used to combat tuberculosis, which is a bacterial disease, may significantly boost human immunity so that it can fight the virus that causes Covid 19, or that the vaccine will prevent abrasion at all.
These experimental doses will be provided to doctors and nurses who are at significantly increased risk of respiratory disease, as well as to the elderly who make up most of the infected and the victims.
A tuberculosis vaccine was used because the Covid 19 virus causes severe damage to the human respiratory system, or the cause of it is pneumonia in more severe cases.
It is expected that a scientific team from the Netherlands will conduct the first of these experiments, during this week, and it will include 1000 people who work in health care.
In the attempt, participants take a sample of a vaccine known in the medical environment as "CBG" and originally used to prevent tuberculosis.
Scientists are trying to take advantage of existing vaccines to combat the scourge of Covid 19, because updating a vaccine for "Covid 19" lacks waiting for a period that varies between one and 18 months.
The researchers attribute the delay to the need for any vaccine to have sufficient test time, in order to monitor any adverse side effects, despite the escalating conditions.
Vaccines often help the human body defense and resistance to a specific disease, by countering the antibodies related to one type of virus.
Even the vaccine that will be tested in the Netherlands may also strengthen the immune system and make it able to fight diseases other than tuberculosis.
At a time earlier, the Danish scientists Peter Abe and Kristen Stapel stressed that the BCG vaccine protected more from bruising from infectious diseases during the year following the introduction of a specific amount of it.
In 2014, a study commissioned by the World Health Organization showed that the vaccine significantly decreased the infant mortality rate, but a review in 2016 recommended more attempts.
