Moderna’s topline results are comparable to the results seen with GlaxoSmithKline’s vaccine, which were announced past October; GSK’s vaccine was reportedly 82% effectual astatine preventing little respiratory symptoms from RSV successful older adults. And they’re supra the results seen with Pfizer’s version, which has been shown to beryllium astir 66% effectual astatine preventing these symptoms. Both GSK and Pfizer’s vaccine look highly effectual astatine preventing terrible RSV, portion Pfizer has also shown palmy late-stage results for its maternal RSV vaccine, which is fixed to mothers to support newborns from terrible infection. Meanwhile, earlier this month, the FDA agreed to reappraisal a imaginable support for Sanofi and AstraZeneca’s antibody attraction for RSV, which looks to support infants from terrible illness earlier their expected archetypal bout with RSV—a attraction that has already won approval successful the European Union arsenic of past year.

These interventions aren’t apt to supply lifelong immunity—Moderna has already said that it expects its vaccine to beryllium fixed yearly—but they should substantially curtail the worst harms of RSV successful high-risk populations if wide accessible and adopted.

Pfizer and GSK person already filed for regulatory support of their older big vaccines, and Moderna plans to record for support earlier the 2nd fractional of 2023. With immoderate luck, 1 oregon much of these treatments volition beryllium disposable to instrumentality earlier adjacent winter’s RSV season—something each the much timely fixed the resurgence of the illness this winter.
