As Covid-19 continues to evolve, it’s important to prove that vaccines provide protection against new strains, Moderna President Dr. Stephen Hoge said Monday.
“The virus is evolving,” Hoge said during a panel hosted by investment institute iConnections. “It's not sitting still.”
He said that the emergence of new strains will “change the calculus” of vaccines.
“I think as we look at the efficacy of any of these vaccines, we should hope and assume that they're going to work across them, but we need to prove that case, time and time again,” Hoge said.
“Now, usually, probably just with measuring the vaccine’s ability to provide neutralizing antibodies in the blood, but in some cases over time we may need to go look at whether or not we're actually protecting in the real world against some of these new strains,” he added.
Hoge said this process could continue for years.
“Until we've got this thing sort of fully suppressed and in control, and people are broadly vaccinated or seropositive and protected against it, it's going to be an ongoing battle for the next couple of years,” he noted.
