This 'new Pan-coronavirus vaccine' developed by US blocks Covid-19, variants, could prevent future pandemic
New Delhi, May 11: With the sudden surge of cases tied to the new variants, the need for a pan-vaccine that simultaneously protects against SARS-CoV-2 and emerging zoonotic coronaviruses comes down to a matter of survival of the fittest.
Recently, US Reasearchers have found a potential new vaccine, called pan-coronavirus vaccine. This vaccine believed to be universal vaccine has so far proven effective against the original SARS-CoV-1, SARS-CoV-2 as well as diminished efficacy against variants discovered in South Africa and Brazil and related bat Coronaviruses that could potentially cause the next pandemic.
Pan-vaccine against SARS-CoV-2
In an article, published on the JAMA Network and written by health experts, including Dr. Anthony Fauci, American physician-scientist and immunologist serving as the director of the National Institute of Allergy and Infectious Diseases, the authors discuss the need for a pan-coronavirus vaccine, which can protect against most or all variants of SARS-CoV-2.
"The further you go, the harder it gets" for a vaccine, says immunologist Dennis Burton of Scripps Research, who often collaborates with Ward.
How does Pan-coronavirus vaccine works?
Pan-coronavirus vaccine triggers neutralising antibodies via a nanoparticle. The nanoparticle is composed of the Coronavirus part that allows it to bind to the body's cell receptors and is formulated with a chemical booster called an adjuvant. Success in primates is highly relevant to humans, said researchers from the Duke University in North Carolina, US.
