I think the intention of the poster before you was to highlight that monoclonal antibodies (likely) actually make more money for big pharma than a course of vaccination. A lot of anti-vaccine rhetoric revolves around vaccines being a big pharma cash grab.
For context, each dose of most of the covid vaccines is about $40 while a round of monocolonal antibody treatment is around $1,500. The vaccine has a dramatic effect in limiting the affects of covid and (as far as I a non-doctor know) stack with monoclonal antibodies if needed. Its just dramatically cheaper if people are vaccinated and not as many people need this treatment.
