During a virtual event held by a financial service group, Oddo BHF, the CEO of Moderna, said that the fear of the vaccine not working is out the window.
“We believe there will be protection potentially for a couple of years, CEO Stephanie Bancel stated.
Bancel also said the “antibody decay generated by the vaccine in humans goes down very slowly.”
According to Reuters, Moderna is close to proving its vaccine works against other strains of the coronavirus.
Batches of Moderna and Pfizer-BioNTech shots have been received in the U.S. Both vaccines require two doses from the same company taken several weeks apart to be fully effective. In unfinished studies, both vaccines appear safe and protective in large.
Moderna’s vaccine efficacy against the coronavirus was 94.1%, and against the severe strain, it came out at 100% effective, CBS News reports. Pfizer’s vaccine is 95% percent effective 28 days after the first dose. The company did not report how long the vaccine will last but said its vaccine trial would continue for another two years.
The CDC announced that reinfection is possible when it comes to COVID-19. That’s why people who have contracted the virus should still get the vaccine. Immunity concerns remain vague—it’s unknown how long natural immunity or immunity someone gains from getting having contracted the virus, last because it can vary from person to person. However, some evidence has shown it may not last long for COVID-19.
