February 9, 2021 //--- As new COVID-19 variant strains begin to raise questions about vaccine efficacy, two leading scientists are calling on health agencies to invest in vaccines that can be widely effective against a variety of different variants and potential pandemic strains.
Denis Burton and Eric Topol of Scripps Research, wrote an opinion article in the journal Nature, calling on the government to provide substantial financial support for reasonable vaccine design based on broad-based and antibodies.
the vaccine provides immunity to many variants that may have evolved from rapidly mutating viruses.
can also be used as drugs to prevent and treat infections.
(Photo: Www.pixabay.com) Burton and Topol point out that an effective vaccine against COVID-19 can be developed quickly due to certain characteristics of the SARS-CoV-2 virus, especially the prickly protein on the surface of the virus.
warned that the virus driving the next pandemic may not be able to provide such targets, which could significantly slow the development of new vaccines.
even with the emergence of new variants, THE SARS-CoV-2 vaccine could become more of a problem," they wrote.
we call for another pandemic precaution.
" Burton and Topol point out that spectral and antibodies are promising ways to develop vaccines and therapies that could easily adapt to emerging pandemic viruses or rapidly evolve to evade traditional vaccines.
" antibody can be used as a first-line drug to prevent or treat viruses in a given family, including new genealogies or strains that have not yet appeared.
, they can be used to design vaccines for many members of a particular virus family.
"for future pandemics, particular attention needs to be paid to "highly escapist" viruses, which means that their biological properties make it difficult for them to be prevented through medication or vaccines.
example of the virus is HIV, which can remain in the body for years.
