As if it wasn’t already hard enough to convince Americans to get a COVID-19 vaccine, Moderna is now openly admitting one of the nation’s biggest fears: That these vaccines will just keep on comin’.
The idea of trying to get 70% of the nation fully vaccinated was a bold one from the start, especially with an already-established anti-vaccine movement having blossomed over the course of the last several years here in the United States.
Now, these “emergency use” vaccines are up against a network of concerned Americans who’ve been communicating with one another for well over a decade, and the vaccines are not coming out ahead in the debate most of the time.
News of these vaccines needing seasonal boosters could spell even more trouble on the reluctance front.
Moderna said on Thursday a third shot of its two-dose vaccine for the Chinese coronavirus will “likely be necessary” prior to winter — news that follows discussions of ongoing coronavirus booster shots similar to an annual flu shot.
Moderna announced additional data on its vaccine on Thursday, revealing it is maintaining a 93 percent efficacy six months after the last dose of the shot.
“We are pleased that our COVID-19 vaccine is showing durable efficacy of 93 percent through six months, but recognize that the Delta variant is a significant new threat so we must remain vigilant,” Moderna CEO Stephane Bancel said in a statement.
However, the company, which detailed the data during a second-quarter earnings presentation, said the vaccine will “continue to wane and eventually impact vaccine efficacy,” meaning a booster shot will be necessary, likely before the winter months.
“We believe that increased force of infection resulting from Delta, non-pharmaceutical intervention (NPI) fatigue, and seasonal effects (moving indoors) will lead to an increase of breakthrough infections in vaccinated individuals,” the company said in the presentation.
Then came the clincher:
“While we see durable Phase 3 efficacy through 6 months, we expect neutralizing titers will continue to wane and eventually impact vaccine efficacy,” it continued.
“Given this intersection we believe dose 3 booster will likely be necessary prior to the winter season,” Moderna stated.
Further complicating the situation are the emerging COVID-19 variants, some of which have proven to have some efficacy against the existing vaccines. There is no telling whether or not a booster would be effective in those cases.
