and vaccinated people don’t spread the virus…much

The confusion among the public continues. Basically, vaccinated people have a 10% or so chance of getting infected Covid-19 if they are exposed to it. If they are infected, they won’t get seriously ill but they might be able to spread it to un-vaccinated people who might then get seriously ill. If you multiply the probabilities, the odds of getting infected by a vaccinated person and then getting seriously ill are low, and the odds that a given person we are exposed to will be vaccinated is getting higher all the time, so the risk is getting lower all the time. Vaccinated people are being asked to wear masks to help that risk drop as quickly as possible. BUT half the population is hearing “the government is sugar-coating the science” and the other half of the population is hearing “vaccinated people are likely to spread the virus”. Neither of these messages is accurate in my view – I’m hearing the risk is low and getting lower, and we all need to get vaccinated to get the risk as low as possible (which will not be zero, but we can all move on to worrying about other diseases such as antibiotic-resistant syphilis).
