Numerous studies and data sets from various countries, including Denmark, Scotland, and England, have shown negative vaccine efficacy (vaccines lead to more infections and more serious adverse events) for some time now. Those nations that were publishing these data stopped breaking out the data by unvaccinated vs. vaccinated b/c, as you state, such data "can easily be misused." This is a very strange approach to science and policymaking indeed. All data should be made available and if it shows that vaccines aren't working, then the science and policy should adjust -- not implementation of Orwellian data suppression tactics.
