The way that the experts whose study was published in the British medical journal The Lancet put it was that “fully vaccinated individuals with breakthrough infections have peak viral load similar to unvaccinated cases and can efficiently transmit infection in household settings, including to fully vaccinated contacts.” When Bloomberg reported on the study, it cut to the core: “People inoculated against Covid-19 are just as likely to spread the delta variant of the virus to contacts in their household as those who haven’t had shots.” The study only tracked a tiny sliver of those impacted in the global pandemic but followed 621 people for a year. The study’s goal was to look at whether vaccination impacted the spread of the disease, not just whether the vaccine could prevent severe illness or death. It also sought to look at COVID-19 in the context of households, where exposure is repeated over time — not hospitals, workplaces or schools. “We found that the secondary attack rate in fully vaccinated household contacts was high at 25%, but this value was lower than that of unvaccinated contacts (38%),” the study’s authors wrote. They noted that the vaccine did offer greater protection against severe illness among those infected. The authors added, however, that protection offered by a vaccine dipped quickly. “Risk of infection increased with time in the 2–3 months since the second dose of vaccine,” they wrote. “The proportion of infected contacts was similar regardless of the index cases’ vaccination status. We observed transmission of the delta variant between fully vaccinated index cases and their fully vaccinated contacts in several households, confirmed by whole-genome sequencing,” they went on. “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.” One of the study’s co-leaders noted that the report does not disparage vaccine use but that vaccination status is no bar to the spread of the delta variant. “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,” Ajit Lalvani of Imperial College London told Bloomberg. The study said vaccinations alone will not stop the delta variant. “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 researchers concluded. “Our findings help to explain how and why the delta variant is being transmitted so effectively in populations with high vaccine coverage.” Poster Comment: Don't vax me,bro.
