Sorry to interrupt as a non dweller in your part of the world but as someone with strong family links with aviation in the region. The death and hospitalisation rates in countries with high levels of vaccination are much lower for a given level of infection. For a like with like comparison, compare the UK stats for the start of second wave, where there was virtually no vaccination, with the equivalent daily case numbers for the third wave, with high levels of vaccination. They are released every day at 1600 UK time. The vaccinations are not 100% effective but they definitely shift the odds in your favour. No question vaccination works.
Would you rather sit there wondering if you should have been vaccinated or be lying in hospital wishing you had been? Your call.
