MMR vaccine potentially effective against measles, mumps and now, Covid
India TodayA measles-mumps-rubella vaccine could be enhanced such that that it makes one immune to multiple variant strains of the Covid-causing virus, new research in animals suggests. The resulting new vaccine could then confer immunity against measles, mumps and COVID-19, report scientists at The Ohio State University, US, calling it the "MMS" vaccine candidate - for Measles, Mumps and SARS-CoV-2. Thus, the lifelong immunity against measles and mumps that an MMR vaccine confers could likely translate into prolonged protection against Covid in people vaccinated with the MMS, they said in their study published in the Proceedings of the National Academy of Sciences journal. The new MMS vaccine, which would be delivered via the nose, is constructed by inserting a highly stable segment of the coronavirus spike protein into the existing MMR vaccine. The immunity from the MMS vaccine would be effective against the ancestral SARS-CoV-2 virus and two of its variants - Delta and Omicron, the scientists said.
