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.
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.
