Updated COVID vaccines prevented illness from latest variants -CDC

The updated COVID-19 boosters from Pfizer Inc /BioNTech SE and Moderna helped prevent symptomatic infections against the new XBB-related subvariants, offering new evidence of how the vaccines perform against these fast-spreading strains, U.S. officials said on Wednesday.

(MRNA.New studies, conducted by researchers at the US Centers for Disease Control and Prevention, are among the first looks at how the bivalent boosters have continued to work in the real world as the virus has evolved.New studies, conducted by researchers at the US Centers for Disease Control and Prevention, are among the first looks at how the bivalent boosters have continued to work in the real world as the virus has evolved.XBB.

S.On average, people in the study who had not gotten a bivalent booster also had not had a dose of a Covid-19 vaccine in more than a year.On average, people in the study who had not gotten a bivalent booster also had not had a dose of a COVID-19 vaccine in more than a year.Centers for Disease Control and Prevention’s COVID-19 response, told reporters in a briefing.Released last fall, the updated boosters target the BA.Their protection against illness was probably very minimal, they said.4 and BA.The study results show that the updated boosters are most effective for younger adults.5 Omicron variants of the SARS-CoV-2 virus, which are no longer dominant.For adults between the ages of 18 and 49, the boosters cut the odds of getting a symptomatic infection caused by the BA.More people who tested negative had gotten an updated bivalent booster compared with those who tested positive.

The now-dominant XBB-related subvariants are derived from the BA.2 version of Omicron.1.1.Lab studies had suggested that vaccine protection was lower against the XBB variants compared with prior variants, raising questions about how well the vaccines worked against these rising strains of the virus, Jackson said.For the study, researchers reviewed COVID-19 cases from Dec.For adults 50 to 64, the new boosters cut the odds of getting sick with Covid-19 by 43% for BA.1 through Jan.5 and 40% for XBB subvariants.For adults between the ages of 18 and 49, the boosters cut the odds of getting a symptomatic infection caused by the BA.

It showed that the updated vaccine helped prevent illness in roughly half of the people who had previously received two to four doses of the original COVID-19 vaccine, CDC said.How long protection lasts For people who are wondering whether the protection from the bivalent booster they got in September has worn off by now, it’s too early to know how waning would work with these new two-strain shots, Link-Gelles said.The CDC said the updated vaccine worked similarly against BA.So far, there’s little evidence of waning effectiveness two to three months after people got their shots.5-related infections and XBB/XBB.1.We know from the older vaccines that we do see protection decrease over time, especially against symptomatic infection.We know from the older vaccines that we do see protection decrease over time, especially against symptomatic infection.5-related infections.She said it’s important to think of them on population level.

It was 52% effective at preventing infections against BA.Researchers don’t have data past three months, she said, but based on experience, she would expect protection against severe disease and death to be higher and last longer than these results against infections.5 and 48% against XBB/XBB.“We will continue to monitor it over time in the coming months,” she said.1.The study authors said that these are just estimates of how well the vaccines are protecting people against an infection that brings on symptoms like cough or fever.5 among those aged 18-49.Effectiveness fell to 37% against BA.“What we know from past experience is generally that the vaccines protect better against more severe disease.“What we know from past experience is generally that the vaccines protect better against more severe disease.Just like with overall protection, what we’ve seen in the past is, your protection lasts longer for more severe illness,” Link-Gelles said.

5 and 43% against XBB/XBB.1.Asked how well the two-strain vaccines may be working compared with the older one-strain shots, Link-Gelles said it was impossible to know.5 among those aged 65 years and older.“We can’t in the US do a direct, head-to-head comparison of the monovalent and the bivalent vaccines because they were never authorized at the same time,” she said.Although not reflected in the study, Jackson said data to be released later on Wednesday shows the updated vaccine reduced the risk of death from COVID-19 by more than twofold compared with vaccinated people who had not received the updated booster.Because protection wanes over time, you’d need to compare groups of people who got each kind of shot at the same time.The updated shot also reduced the risk of death from COVID-19 by nearly 13-fold in people who are unvaccinated.“What we know from past experience is generally that the vaccines protect better against more severe disease.

Study author Ruth Link-Gelles of the CDC said overall, the vaccines cut the risk of symptomatic infection by about half on a population, but individuals see a different benefit based on their risk factors.CDC sped study results The CDC said it was able analyze the data and publish it so quickly thanks to the use of a shortcut.CDC sped study results The CDC said it was able analyze the data and publish it so quickly thanks to the use of a shortcut.Link-Gelles said the estimates are for symptomatic infection, which CDC defined as one or more symptom of COVID-19.Given the findings, the CDC urged people to stay up to date on their recommended COVID-19 vaccines.The tests used in the study rely on a series of probes, or markers, to identify a positive case.XBB.Some variants of the virus that causes COVID-19 have mutations in their spike protein that causes one of the test markers to fail.1.This is called an S-gene target failure.“What this tells us is that people that had the bivalent vaccine were better protected than people that were up to date previously, had all their monovalent doses and had not gotten the bivalent vaccine,” Link-Gelles said.
