A COVID-19 vaccine that could provide protection against both existing and future strains of the COVID-19 virus, and other coronaviruses, and cost about $1 a dose has shown promising results in early animal testing.
Vaccines created by UVA Health’s Dr. Steven L. Zeichner and Virginia Tech’s Dr. Xiang-Jin Meng prevented pigs from being becoming ill with a pig model coronavirus, porcine epidemic diarrhea virus. The vaccine was developed using an innovative approach that Zeichner said might one day open the door to a universal vaccine for coronaviruses, including coronaviruses that previously threatened pandemics or perhaps even coronaviruses that cause some cases of the common cold.
Their coronavirus vaccine offers several advantages that could overcome major obstacles to global vaccination efforts. It would be easy to store and transport, even in remote areas of the world, and could be produced in mass quantities using existing vaccine-manufacturing factories.
