Cost of coronavirus treatment. Estimated by ICER will be between $80 to $4,460 per person with 80% of the population needing vaccinated. So the lower estimate (which is only for developing countries) will be 480 billion dollars, which you will have to pay for. How often will you need it? Estimates vary, it maybe between 2 and 12 months. You will require at least 2 injections and will probably get ill after the treatment. Woohoo.
