Covid, The Lancet study: 'Vaccine saves lives but does not stop infections, requirement to be reassessed'
The Lancet on Covid: ‘Vaccine should not replace use of safety devices, spacing and tracking’
“The impact of vaccination on Sars-CoV-2 transmissibility still needs clarification.
A prospective cohort study in the UK on the transmission of Sars-CoV-2 between unvaccinated and vaccinated individuals provides information to be considered when establishing vaccination policies.
This study showed that the impact of vaccination on the transmission of Sars-CoV-2 and its variants does not appear to be significantly different from that among unvaccinated people.
The scientific journal The Lancet published the study with an article entitled ‘Transmissibility of Sars-CoV-2 among fully vaccinated individuals’
(https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(21)00768-4/fulltext) which, starting from the studies ‘on the efficacy of vaccines that have conclusively demonstrated the benefit in reducing symptomatic and severe individual disease, with consequent reduction of hospitalisations and admissions to intensive care units’, addresses the issue of ‘contagion’ and the related mandatory vaccination policies, as in the case of the United States.
The events in Israel are also reported to have resulted in ‘Covid-19 infections among fully vaccinated healthcare workers (…).
There is evidence that the viral peak in the upper airways of the lungs is similar in vaccinated and unvaccinated individuals,’ the study points out.
Citing the US.
“A recent investigation by the US Centers for Disease Control and Prevention of a Covid-19 outbreak in a Texas prison showed the same presence of infectious virus in the nasopharynx of vaccinated and unvaccinated individuals.
Researchers in California observed no substantial difference between vaccinated and unvaccinated individuals in terms of Sars-CoV-2 viral load in the nasopharynx, even in those with proven asymptomatic infection.
The Lancet: reconsidering current vaccination policies
“Current evidence,” concludes the Lancet article, “suggests that current mandatory vaccination policies can be reconsidered and that vaccination status should not replace mitigation practices, such as mask wearing, physical distancing, and contact tracing surveys, even within highly vaccinated populations.
