Tests in mice of a possible vaccine administered through the
patch the size of a finger tip have shown that it can induce an immune response
to the coronavirus at levels that could prevent infection, said scientists at
the University of Medicine School of Medicine. Pittsburgh.
Researchers from around the world are working to develop
possible treatments or vaccines against
the respiratory disease that has killed
nearly 47,000 people and infected nearly one million in a few months.
The team of researchers said they made rapid progress in
developing a possible COVID-19 vaccine after working on other strains of the
coronavirus that causes Acute and Severe Respiratory Syndrome (SARS) and
Respiratory Syndrome of Middle East (MERS).
"These two viruses, which are closely related to
SARS-CoV-2 (the new coronavirus causing the COVID-19 pandemic), teach us that a
particular protein is important in inducing immunity against the virus,"
Andrea said. Gambotto, associate professor at the Pittsburgh School of
Medicine.
When tested in mice, the prototype vaccine - which
researchers have called PittCoVacc - generated "a surge of
antibodies" against the new coronavirus within two weeks.
