As lockdowns ease in New South Wales, Victoria and the ACT, and people return to work and socialising, many of us will be mixing more with others, even though a section of the community is still unvaccinated.
Many vaccinated people are concerned about the prospect of mixing with unvaccinated people. This mixing might be travelling on trains or at the supermarket initially.
But also at family gatherings, or, in NSW at least, at pubs and restaurants when restrictions ease further, slated for December 1.
Some people are wondering, why would a vaccinated person care about the vaccine status of another person? Briefly, it’s because vaccines reduce the probability of getting infected, which reduces the probability of a vaccinated person infecting someone else.
