PRIOR COVID INFECTION PROVIDES JUST AS MUCH PROTECTION AS VACCINES, NEW STUDY FINDS
The excellent news, Johnson mentioned, is that the bivalent mRNA vaccine protects in opposition to probably the most extreme COVID-19 outcomes, together with hospitalization and significant illness (ICU admission and loss of life), Johnson mentioned.
The not-so-good information: The sturdiness or length of safety was not nice, she famous.

“Sturdiness was higher for stopping important COVID-19 illness, at 50% at 4 to 6 months after vaccination.”
The vaccine was discovered to be efficient for longer durations in folks with out immunocompromising situations (weakened immune methods).
“The vaccine impact on reducing severity or stopping lengthy COVID shouldn’t be endlessly.”
“These knowledge help up to date suggestions permitting further elective bivalent COVID-19 vaccine doses for sure high-risk populations,” the CDC acknowledged in a dialogue of the research findings on its web site.

Solely 20% of US adults receiving booster doses

‘COVID continues to be with us’
Whereas circumstances and deaths proceed to say no within the U.S., Siegel warned that “COVID continues to be with us,” citing the “enormous” outbreak at the moment taking place in China.
“Right here within the U.S., with XBB subvariants nonetheless predominating, we do have much more inhabitants immunity than China does,” he famous.

“That immunity is because of each prior an infection in addition to vaccination,” he mentioned.
“However the vaccine impact on reducing severity or stopping lengthy COVID shouldn’t be endlessly — after a yr, that impact has actually declined considerably,” he additionally mentioned.
Vaccine offers ‘broader protection’
“This research regarded on the sturdiness, or how lengthy the bivalent mRNA vaccine protects folks from hospitalization and important sickness from COVID-19,” Johnson instructed Fox Information Digital.
What the research didn’t consider was earlier COVID-19 an infection or pure immunity, she defined.
“For adults, the vaccine effectiveness dropped from 62% at two months after vaccination to 24% at 4 to 6 months for cover in opposition to COVID-19 hospitalization,” a health care provider mentioned. (iStock)
