Fauci: Booster Shots Will Almost Certainly Be Required, But When Is Uncertain.

Americans who have been immunized against the coronavirus will almost certainly require a booster shot to ensure continued protection, according to Dr. Anthony Fauci.

“I don’t anticipate that the durability of the vaccine protection will be infinite — it just isn’t,” the infectious disease expert said before a Senate Appropriations subcommittee. “So I would imagine we will need, at some point, a booster. What we’re figuring out right now is what that interval will be.”

Researchers are continuing to monitor those who participated in the vaccines' original clinical trials to determine their resiliency, according to Fauci, and it has been determined that the protection can last anywhere from six months to a year.

Last week, the CEOs of vaccine manufacturers Pfizer and Moderna suggested that Americans may require a booster shot eight to twelve months after their initial immunizations.

People at highest risk (elderly, healthcare workers) were vaccinated in December/January, so I would start [in] September for those at highest risk,” Moderna CEO Stéphane Bancel told Axios.

However, Fauci has advised against naming a timeline until one is established.

“We may not need it for quite a while,” he said in an interview with The Washington Post last week. “We are preparing for the possibility that we might need boosters, but I think we should be careful not to tell people that inevitably X number of months from now, everyone will need a booster. That is simply not the case.”

Booster shots may also be used to provide increased protection against emerging variants, according to a recent Stardia interview with an infectious diseases expert.

“We have increasingly reassuring information about durability, but the variant question remains open — and a little ominous, I think, given what’s happened across the subcontinent, and how we’re seeing an increase in the Brazilian variant here in the United States,” said Cameron Wolfe, an associate professor of medicine at Duke University’s School of Medicine who specializes in infectious diseases.

Vaccine manufacturers have stated that they are preparing to make changes to their vaccines to better combat variants. Moderna recently announced that it has developed a variant-specific booster shot that has been shown to protect those fully vaccinated against COVID-19 against variants from Brazil and South Africa, both of which were detected in the United States in January of this year.
