philosopher, people who take vaccines and are careful are not negatively affecting anyone, except that you feel you are surrounded by sheep, and we probably also give you an ayn hara.
people who do not take vaccines and/or are not careful contribute to continuation of the pandemic, causing damage to the society, and dead and sick people. Even people who are vaccinated can still be infected. As we talked before, 95% protection from infection is based on the same behavior with and without vaccine. If you take a vaccine and relax behavior while being in the same treat environment, your risk is still high. For example, if a person is in the group of unvaccinated uncareful people and is close to them for a sustained time period, he will get infected, even as his chance of getting seriously sick is not high. Still, it is possibly some damage to health that we do not know well enough. It is seen now in Israel – even with very low overall rates, the moment rules are relaxed, one person can infect tens of people.
Most significant benefit from the vaccine comes from the group effect – R0 <1: each person infects on average less than 1 person and soon everyone around is clean. Currently, US R0 is just lower than 1 – 0.85 – it achieved lowest point of 0.75 on May 25 and went up for the two weeks after that, when everyone started relaxing the rules. Most Europe (except UK) and Canada have now R0=0.5 that is decreasing dramatically. US also now vaccinating 0.3% of population per day – as much as under Trump, while Europe does 0.8% per day.
