Washington, Apr 8:
A novel vaccine fully protects mice against a lethal dose of MERS, a close cousin of the novel coronavirus that causes COVID-19, scientists said on Tuesday.
The vaccine uses a harmless virus to deliver a MERS coronavirus protein into cells to generate an immune response, said the researchers from researchers at the University of Iowa and the University of Georgia in the US.
It may hold promise for developing vaccines against other coronaviruses diseases, including COVID-19, they said.
The team tested the MERS vaccine candidate in mice engineered to be susceptible to the MERS coronavirus.
The researchers are planning more studies in animals to test the ability of PIV5-based vaccines in preventing disease caused by SARS-CoV-2.
MERS (Middle East Respiratory Syndrome) and COVID-19 are both caused by coronaviruses.
