According to new research, people vaccinated against COVID are just as likely to spread the delta variant of the virus as those who are unvaccinated.
The yearlong study focused on 621 people in the United Kingdom with mild COVID. Scientists found their peak viral load was similar regardless of vaccination status.
Twenty-five percent of vaccinated household contacts contracted the disease from an index case while 38 percent of those who hadn’t had shots became infected.
“Our findings show that vaccination alone is not enough to prevent people from being infected with the delta variant and spreading it in household settings,” said Ajit Lalvani, a professor of infectious diseases at Imperial College London who co-led the study. “The ongoing transmission we are seeing between vaccinated people makes it essential for unvaccinated people to get vaccinated to protect themselves.”
The same study showed immunity from full vaccination wore off in as little as three months.
