US scientists have discovered an antibody that can protect against several types of the recent Covid 19 virus, so far it has been successfully tested in mice.
The study, by experts from the Washington University School of Medicine in St. Louis, Missouri, was published in the latest issue of the online research journal Immunology.
In this regard, the relevant press release states that this antibody binds to a spike on the surface of Covid 19 virus (SARS CoV2) which not only helps the virus to enter human cells. Yes, it is more or less the same.
That is, the spike is the same in almost all variants of the Covid 19 virus, which a successfully binding antibody can protect against several strains of the virus simultaneously.
To find the most effective antibody against the novel corona virus, scientists have identified 43 antibodies made from specific human cells that specifically attack the virus spike.
Nine of these antibodies performed well against the Covid 19 virus in human cells grown in the petri dish.
When these antibodies were tested on mice, it was found that 2 of these antibodies performed very well against almost all existing strains of the Covid 19 virus (including the Delta variant).
When further experiments compared the two antibodies, it was found that the antibody called "SARS2-38" showed four dangerous types of covid 19 (alpha, beta, gamma and delta). In addition, two emerging new species (Kappa and Iota) and several other species that have not yet been given a formal name have been successfully prevented from spreading.
Scientists estimate that even small amounts of the "SARS2-38" antibody will be helpful in preventing almost all types of corona virus.
Experts also estimate that only 4 out of every 10,000 people will not benefit from this antibody. However, the true efficacy of this antibody (SARS 38-2) will only come to light when it is tested on humans.
How long will experts be allowed to start human experiments with this antibody? For now, it is too early to say.
