The study is published in BMC Infectious Diseases and used data from the sixth wave of COVID-19 cases seen in Tokyo caused by the BA.1 and BA.2 Omicron subvariants from January to May 2022. ... Estimated 8.5 million infections indirectly prevented The investigators calculated that mass vaccination campaigns directly prevented 640,000 COVID-19 cases during the sixth wave, and indirectly prevented as many as 8.5 million infections."

Measuring the impact of COVID-19 vaccination can provide valuable information to guide public health policy and improve our understanding of population-level protection. It is critical to achieve high vaccination coverage to benefit from its valuable direct and indirect effects." https://bmcinfectdis.biomedcentral.com/articles/10.1186/s12879-023-08748-1 Edited November 8, 2023 by TallGuyJohninBKK 1 2 Link to comment Share on other sites More sharing options...
TorquayFan Posted November 9, 2023 Share Posted November 9, 2023 (edited) So that's "according to a new model" - I guess it must be true then Whether mRNA vaccines were actually advisable to counter at that time, the much milder Omicron variant, is a moot point, (it's MHO that the vaccines might have been justifiable against the earlier fierce versions of the virus, Delta and so on).
