CDC study admits COVID boosters not very durable, but claims ‘little remaining protection’ for opt-outs

According to a new study from the Centers for Disease Control and Prevention (CDC), the majority of adult Americans haven’t had an updated COVID-19 booster shot in more than a year, and, even though they aren’t very effective six months after getting them, the CDC warns that those un-jabbed people have “relatively little remaining protection” against hospitalization.

As of May 10,  reportedly just 20% of U.S. adults have opted to take the updated shots, which are meant to target certain subvariants in addition to the original COVID-19 strain.

According to the study, “U.S. adults who previously received a monovalent vaccine but had yet to receive a bivalent mRNA booster” might have “relatively little remaining protection against COVID-19–associated hospitalization compared with unvaccinated persons, although might have more remaining protection against critical illness.”

The problem is, the boosters aren’t very durable.

“For adults, the vaccine effectiveness dropped from 62% at two months after vaccination to 24% at four to six months for protection against COVID-19 hospitalization,” Arizona physician Dr. Shana Johnson, who reviewed the study, told Fox News Digital. “Durability was better for preventing critical COVID-19 disease, at 50% at four to six months after vaccination.”

The bivalent mRNA vaccine was found to remain effective for longer in people who don’t already have a weakened immune system.

Despite its durability issues, the CDC still recommends “all eligible persons” subject themselves to it.

“These data support updated recommendations allowing additional optional bivalent COVID-19 vaccine doses for certain high-risk populations,” the study’s authors write. “All eligible persons should stay up to date with recommended COVID-19 vaccines.”

But with only 1 in 5 adults in America willing to roll up their sleeves, Dr. Marc Siegel, professor of medicine at NYU Langone Medical Center, admits, “Uptake has been quite low.”

“It makes complete sense for adults — especially those in high-risk groups, including the elderly and those with chronic disease — to have a bivalent shot if they haven’t already had one,” he told Fox News Digital.

He warns that even though cases and deaths in the U.S. continue to decline, “COVID is still with us.”

Just look at the “huge” outbreak China is currently facing.

“Here in the U.S., with XBB subvariants still predominating, we do have a lot more population immunity than China does,” Siegel said. “That immunity is due to both prior infection as well as vaccination.”

“But the vaccine effect on decreasing severity or preventing long COVID is not forever — after a year, that effect has certainly declined significantly,” he added.

“This study looked at the durability, or how long the bivalent mRNA vaccine protects people from hospitalization and critical illness from COVID-19,” Johnson said, but it didn’t evaluate natural immunity or prior COVID-19 infection.

“The authors note that since a large portion of the population has experienced COVID, they have some level of protection from natural immunity, but the vaccine provides additional benefit,” she explained. “Natural immunity confers a benefit, but the vaccine provides broader coverage, which protects against more variants.”

On Twitter, people are skeptical.

For many, it comes down to a matter of “trust.”
