Just going to add that you most likely won’t get that new antiviral pill in early stages because its currently being reserved for severe cases/hospitals. Monoclonal antibodies are also not being given for omicron in many places since they may not be effective against it.

For those that are vaccinated their bodies can make antibodies right away and mount a response, they may still get sick but they are less sick than they would be without immunity. People that are unvaccinated most likely wont receive treatment until they are having trouble breathing and need to be hospitalized. And even then treatment is limited. Right now nearly all COVID patients in the ICU are unvaccinated.
