Have you looked into the details of developing a vaccine? There are dangers. For instance, for polio, from sciencehistory.org: During his lifetime Sabin staunchly defended his live-virus vaccine, refusing to believe any evidence that it could cause paralytic poliomyelitis. Salk, for his part, believed that killed-virus vaccine produced equivalent protection in individuals and in communities without any risk for causing paralysis. That's just a hint of what could go wrong with a virus vaccine. Can you imagine the response from the anti-vax movement? There are issues with the "delivery mechanism". Remdesivir requires injections. Lab tests with monkeys gave injections 12 hours after first exposure and every 24 hours after that. Are you willing to get that many injections... starting 12 hours after (potential) exposure when symptoms don't show up for 4-5 days? Remdesivir requires about 8.5 liters of starting material and about 20 "process steps" to create each injection. How do you scale that up to 7 billion people? There are issues of "simple" treatments with antibodies. But they don't give protection against re-infection. A vaccine may give "clearing" (reducing the viral load) or "sterilizing" (eliminating the virus) protection. There are a thousand issues with a vaccine. Oh, and corona viruses have been known since the last 1930 and there is still no vaccine.
