Vaccinated just as likely to spread delta variant within household as unvaccinated: study
People who have received COVID-19 vaccinations are able to spread the delta variant within their household despite their vaccination status just as easily as unvaccinated individuals, a new study published on Friday shows.
According to the study published in The Lancet Infectious Diseases journal, people who contracted COVID-19 had a similar viral load regardless of whether they had been vaccinated. The study further found that 25 percent of vaccinated household contacts contracted COVID-19. while 38 percent of unvaccinated individuals were diagnosed with the disease.
Researchers examined 621 symptomatic participants in the United Kingdom over a year.
“Although vaccines remain highly effective at preventing severe disease and deaths from COVID-19, our findings suggest that vaccination is not sufficient to prevent transmission of the delta variant in household settings with prolonged exposures,” the study said.
In contrast, researchers noted that the vaccination was more effective at curbing transmission of the alpha variant within the household, at between 40 and 50 percent.
