That is true, however with vaccines it is needed to vaccinate a large percent of the world population to work. Short term a vaccinated person is good, but vaccinations lead to mutations in un vaccinated people. Then the vaccine does not work so well. Treatments are only needed if the patient needs them, a much smaller population. People who are not vaccinated either build immunity by being exposed to the virus as needed or get treatment if needed. I’m not anti vaccine, I am very pro vaccine because it is the best we have now, but treatments are very much needed.
