>Sure there is a small population that would get vaccinated but genuinely can not due to a medical issue but that scenario is no different than the seasonal flu and other viruses. There is a difference. Covid is 10 times more lethal than the average flu. It's not always that they can't either, it's also that their body won't develop enough antibodies. Main reason for lockdown is so that your hospitals can keep functioning, or in the case of New Zealand, so that you can go back to complete normal life except for travel outside the country.
