Dr. Fauci Says This is Why You Need a Booster Shot

Today, the Biden administration outlined a plan for a subset of Americans to get their booster shots starting September 20th. Why do we need a third shot now? “It has been such an almost reproducible phenomenon with COVID-19,” Dr. Anthony Fauci, the chief medical advisor to the President and the director of the National Institute of Allergy and Infectious Diseases, said at the White House COVID-19 Response Team Briefing. “If you wait for something bad to happen before you respond to it, you are considerably behind your real full capability for a response. You want to stay ahead of the virus. And if you look at the indications that we’ve had, you don’t want to find yourself behind playing catch-up. Better stay ahead of it than chasing after it.” He explained why you need one.

Dr. Fauci provided “the immunological basis that would support a third boost to mRNA immunization. First, antibody levels decline over time. Second, higher levels of antibody are associated with higher levels of efficacy of the vaccine. Third, higher levels of antibody may be required to protect against the problematic Delta variant and finally a boost to mRNA’s immunization increases antibody titers by at least 10 fold and likely much more.”

“Let’s take the first concept that antibody levels decline over time,” said Dr. Fauci, “in this case, following two mRNA immunizations. At day 29, when you get your second shot, …the level of antibodies go up at 43 days. But unfortunately, “the antibody levels against those variants declined over time.”

Dr. Fauci explained that “higher levels of antibody are associated with higher levels of vaccine efficacy.” He mentioned a recent paper and “it shows is that a model of vaccine efficacy in this case, based on the Moderna phase three, showed that four weeks after the second dose, that what you have as a serum neutralization titer of one to a hundred, which goes up from the vertical red line, that gives you an efficacy of 91%. But if you look at the dark black line going from left to right, as you go further up, you get a higher degree of efficacy. So the higher, the neutralization titer, the higher degree of efficacy of the vaccine in this model.”

“Higher levels of antibody may be required to protect against Delta,” said Dr. Fauci. He showed data “both from Moderna and a paper in the New England Journal” that showed “you’ll get a dramatic increase in antibody titers when you do a third immunization dose. And so in summary, the current immunological data that indicate that antibody levels decline over time, higher levels of antibody are associated with a high level of efficacy. Higher levels of antibody may be required to protect against Delta. And this booster mRNA immunization increases antibody titers by multiple fold, all of this support, the use of a third boost to mRNA immunization to increase the overall level of protection.”

There’s “a plan for Americans who received the Pfizer-BioNTech and Moderna coronavirus vaccines to get a booster shot eight months after receiving their second doses, starting Sept. 20. Health care workers, nursing home residents and other older adults who were vaccinated early will be first in line, starting then, contingent on authorization by federal regulators,” says the New York Times. “We are starting to see evidence of reduced protection against mild and moderate disease,” officials of several federal agencies said in a prepared statement.
