The effectiveness of the medical mask 50%

Japanese researchers have proven that masks can protect from corona virus particles spread in the air, but even the finest types cannot completely stop the risk of transmission.

And the Japanese newspaper Japan Times reported that scientists at the University of Tokyo built an isolated room and put in it statues faces facing each other, one of which is equipped with a spray that simulates a cough and spreads real particles of the Corona virus, while the rest of the heads simulate the natural breathing process while the virus is flying in the air.

The researchers found that the cotton muzzle limited the inhalation of the virus by 40%, while the medical muzzle “N 95” limited it by 90%, but even with the medical mask tightly placed on the face of the statue, particles of the virus leaked through it.

And when I put a muzzle, whether cotton or medical, on the face of the statue that spreads the disease, it limited the spread of the virus by 50%.

A day after the death of a volunteer in Brazil … UK scientists confirm the effectiveness of the AstraZeneca vaccine

Researchers in the United Kingdom claim that the “Covid-19” vaccine, AstraZeneca, behaves as expected in the human body, in research released a day after the Brazilian authorities announced the death of one of the volunteers in the experiment.

And the group of independent scientists in the United Kingdom says in their work, that the vaccine strictly follows the intentions of its creators once it is injected into the human body, according to Russia Today.

The study was conducted by several virologists not affiliated with AstraZeneca, and is led by Dr. David Matthews, of the University of Bristol, and has only been published as a draft publication so far, which means that it has not yet passed the peer review process. It states that the vaccine accurately copies and executes the genetic instructions programmed into it by its designers.
