A vaccine is a fraction of the cost of treatment, and it has no long-term side effects. Even better, a vaccine reduces the chance for a virus to mutate.
Treatments, even if they work, are going to have side effects, and there are still unknown risks from a severe (unvaccinated) infection anyway.
Vaccines are a miracle of proactivity, and there's no reason to try to replace them with something expensive, risky, and reactive.
