A brief report in the prestigious medical journal comments on the impact of vaccination on community transmission of SARS-CoV-2.
[One] study showed that the impact of vaccination on community transmission of circulating variants of SARS-CoV-2 appeared to be not significantly different from the impact among unvaccinated people.
The report cites other studies in the same vein before concluding:
Thus, the current evidence suggests that current mandatory vaccination policies might need to be reconsidered, and that vaccination status should not replace mitigation practices such as mask wearing, physical distancing, and contact-tracing investigations, even within highly vaccinated populations.
According to The Lancet, Covid vaccines have efficacy for individuals, but that efficacy doesn’t translate into a reduction in community transmission.
