Американските изследователи разработват нова ваксина за мРНК за борба с Covid-19
Amid fresh surge in Covid-19 cases, a team of US researchers has developed a new type of mRNA vaccine that is more scalable and adaptable to tackle continuously evolving viruses such as SARS-CoV-2 and H5N1.
While the currently available mRNA vaccines are highly effective at inducing an immune response against Covid, they present challenges like the high amount of mRNA needed to produce them and the constantly evolving nature of the pathogen.
" The virus changes, moving the goal post, and updating the vaccine takes some time, " said senior author Suresh Kuchipudi, chair of Infectious Diseases and Microbiology at the University of Pittsburgh School of Public Health.
To address these challenges, the researchers created a proof-of-concept Covid vaccine using what's known as a „ Транс-амплифициране “ на мРНК платформата.
В този метод мРНК е разграничена на два фрагмента-последователността на антиген и последователността на реплика-последната от които може...
