The nation's leading infectious disease expert says protection from a potential coronavirus vaccine may be short-lived. As companies are ramping up efforts, Dr. Anthony Fauci said he does not know how long antibodies might provide immunity against infection.
Why that matters? Antibodies could determine how often someone might need to receive a vaccine to prolong protection. Fauci added the potential immunization will not be like a measles vaccine, which the CDC says generally offers lifelong immunity. This would likely be something more like the annual flu vax.
So what about President Trump’s weekend remarks saying that “99-percent of coronavirus cases are harmless?” Experts may be pushing back, but the White House is doubling down. Speaking with reporters, White House Press Secretary Kayleigh McEnany said the remark was a "factual statement rooted in science" adding that the case mortality rate in the U.S. is very low and its much lower than other countries.
