(Hill) – One Oxford University Studies published on Monday showed that the two-dose COVID-19 vaccine produced a lower antibody response against the omicron strain, suggesting that this variant could lead to more infections for those already vaccinated. fully vaccinated and previously infected.

The study has yet to be peer-reviewed, which recorded a “Significantly reduced” in the number of neutralizing antibodies, among participants who received two doses of AstraZeneca or Pfizer-BioNTech vaccine.

The results did not provide evidence that the omicron strain caused more severe illness, hospitalization, or death in vaccinated individuals. But it turns out that the variant could lead to more cases among those given the two doses.

The study adds to growing evidence in favor of boosting the dose that has been shown in other studies to increase antibody levels against the omicron strain.

“Increasing vaccine uptake in unvaccinated people, and encouraging a third dose, remains a priority to reduce transmission and the likelihood of severe disease,” an Oxford University statement said. .

The researchers examined how an omicron virus isolate affected the immune response in blood samples of previously vaccinated people in a study group.

Lead author Gavin Screaton, head of the university’s department of health sciences, said the study should “emphasize the message that people recommended for booster vaccinations should take it”.

“Although there is no evidence of an increased risk of severe illness or death from the virus in vaccinated populations, we must remain cautious, as more cases would still impose significant for health care systems,” Screamon said in a statement.

The preprint study comes as the UK is sounding the alarm about omicron variation, with the Prime Minister Boris Johnson booster booster and warned of an upcoming “omicron tidal wave”.

Britain has raised its COVID-19 alert level to its second-highest as omicron infections have doubled in the country “every two to three days,” Johnson said on Sunday. The UK Health Security Agency has predicted that the virus will prevail by mid-December.

More than half of the states, as well as DC, have reported omicron variant cases.
