In recent weeks, we have seen the gradual implementation of vaccines Kovid-19. It is up to the health authorities in each country to choose which of them to use. Names like Pfizer, Sputnik, Astrogeneca, Moderna or Johnson & Johnson often appear in the media.
Today, the question arises about the effectiveness of these vaccines against variants of Kovid-19. True, since the beginning of the epidemic, the virus has been evolving. Today we will talk about South African, Indian or Brazilian variants. Experts who have encountered the antigenic variation of Kovid-19 suggest the creation of a Universal vaccine.
A study recently published in the journal Nature shines hope on the existence of such a vaccine. Dr. Barton Haynes, director of the Duke Human Vaccine Institute (DHVI) and co-author of the book, said the compensation would be released soon.
Neutralizing antibody vaccine
Researchers from the University of Pennsylvania and the 3M Corporate Research Materials Laboratory at the University of Pennsylvania participated in this tutorial at Duke University. In their study, they induced the development of the messenger RNA vaccine.
Will have the ability to defeat this new candidate SRAS-CoV-2, Its variants and other coronaviruses as well. Circulation of such a vaccine makes it possible to prevent future epidemics.
According to experts, this vaccine contains nanoparticles that can use a common loophole for coronaviruses in their cell receptor binding domain. An adjuvant called 3M-052 / Alum is associated with this nanoparticle to stimulate the immune response. The vaccine can target the domain that binds coronaviruses with antibodies.
Tests were performed on monkeys
This universal vaccine has been tested in monkeys. Some of them were vaccinated against the viruses of SARS-CoV-2 and SARS-CoV-1. The results obtained by the researchers at the end of these tests were very encouraging.
This is because the subjects receiving the vaccine produce antibodies that neutralize it. Therefore, they were able to prevent SARS-CoV-2, but also the British, South African and Brazilian variants. Faced with these results, the authors of this study are optimistic.
According to them, this vaccine can “Ignite quickly or extinguish the new pandemic.” “ To be continued …
