>A study was published in the Canadian Medical Association Journal (CMAJ) titled “Impact of population mixing between vaccinated and unvaccinated subpopulations on infectious disease dynamics: implications for SARS-CoV-2 transmission,” on April 25, 2022. Set in the context of Covid-19 and based on a simulation model study of various mixes of unjabbed and jabbed populations, the study concluded that the unvaccinated pose a risk to the vaccinated.
This immediately made waves in the media in many parts of the world: WION News, The Hamilton Spectator, NDTV (India), DNA (India), Times Now (India), etc. The above conclusion of the study goes against the layperson observation that highly jabbed populations have faced repeated surges: e.g. Israel, various countries in Europe, USA, etc., while populations with only a low percentage of people jabbed haven’t had surges: India, various African countries, etc. In fact in many places like Singapore, South Korea, Hong Kong, etc. even the first surge happened only after a high percentage of the population was jabbed.
