With every passing day, it is becoming clear that vaccines have only limited efficacy against the COVID 19 virus. Countries like the UAE, Portugal, Spain and Singapore have vaccinated almost all of their adult population (~100% coverage). But all these countries are reporting large spike in new infections and deaths from COVID 19. The perfect example is that of the United States. 55% of the population fully vaccinated, and yet they are reporting ~2,000 deaths per day now. They haven't given a breakdown of how many of these deaths are among the fully vaccinated people, and that makes me even more suspicious.
Yeah it's not easy. Because even if vaccines do work to some extent, there could be some side effects: more risky behaviors, more viral loads and shedding, and so on. This last winter wave will be the trickiest and most unpredictable.
