Researchers are warning people who received their first COVID-19 vaccine to remain cautious after figures suggest that one in 14 people admitted to hospital with the virus have had at least one vaccine.
Scientists behind the data say the majority would have been infected shortly before or shortly after their first stroke, before adequate immunity to the disease had time to develop.
In the study, only about 1% of people developed symptomatic COVID-19 despite having a jab 21 or more days previously.
That figure may be artificially low because the risk of exposure has dropped significantly this year, the researchers say.
Professor Calum Semple, professor of child health and epidemic medicine at the University of Liverpool, and co-leader of the study, said it was “reassuring” that the number of vaccine failures was very high. low.
But, he went on to say that the number of people acquiring COVID-19 within two weeks of being vaccinated “indicates that people are letting their guard down because they have been vaccinated.”
“There is evidence here that people unfortunately assume that they are protected very quickly after vaccination and that is not the case,” he said.
The study of just over 50,000 patients hospitalized since December 8 revealed 3,842 cases of vaccinated people hospitalized until April 10.
Of these 92% (3,534) tested positive for COVID-19[female[feminine.
This represents about 7% of all hospital admissions linked to the coronavirus.
The data was submitted to the SAGE government advisers of the COVID-19 clinical information network of the ISARIC4C consortium (CO-CIN).
Early analysis shows mortality remains high for people in high-risk vaccination categories who are admitted to hospital with COVID-19 – even though they were vaccinated 21 days previously.
