A newly published study reportedly shows that recipients of the Covid vaccine are just as likely to spread the delta variant within their households as those who are unvaccinated.

People who got Covid had a comparable viral load regardless of whether they had been vaccinated, according to an October 29th study published in The Lancet Infectious Diseases journal. According to the research, 25% of vaccinated household members caught Covid, whereas 38% of unvaccinated people were diagnosed with the ailment.
During the course of the study, researchers reportedly evaluated 621 symptomatic volunteers in the United Kingdom over the course of a year, drawing the conclusion that vaccination doesn’t prevent the spread of the disease:
“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.”
Conversely, Covid vaccines are apparently better at curtailing the transmission of the alpha variant within households, at a rate somewhere between 40 and 50%.
Unsurprisingly, the study reiterated that the best option of for people to continue to get vaccinated or partake in “booster” shots to improve “population immunity”:
“Increasing population immunity via booster programmes and vaccination of teenagers will help to increase the currently limited effect of vaccination on transmission, but our analysis suggests that direct protection of individuals at risk of severe outcomes, via vaccination and non-pharmacological interventions, will remain central to containing the burden of disease caused by the delta variant.”
The research comes as Covid cases have begun to fall throughout the United States, however it is uncertain if this reduction will be sustainable or whether a comeback of cases might occur in the winter.
Former FDA Commissioner Scott Gottlieb predicted earlier in October that the Covid “pandemic phase” would come to an end with the authorization of antiviral pills and Covid vaccines for children, and that the United States would soon transition into a “endemic” phase as Americans come to terms with the virus simply being a part of life:
“So if I was trying to put an endpoint on when this delta wave kind of has moved through the country, it’s probably Thanksgiving and then on the back end of that, we’re going to have hopefully a vaccine available for children.
And at some point before the end of the year we probably will have the orally available drug from Merck if things go well, and that undergoes a favorable review, and I think those two things are going to be sort of the bookend on the sort of pandemic phase of this virus.”
