Herd immunity is irrelevant

Herd immunity should not be a strategy when there is no vaccine
Vaccines are an important part of stopping viruses and illnesses. Making a coronavirus vaccine is more important than herd immunity.

Vaccines are essential for stopping illnesses. An immunized individual is less likely to be a source of infection to others. For a disease with no vaccine, like COVID-19, natural herd immunity would put the responsibility of stopping viral spreading up for chance. Vaccines are not made to give severe symptoms to the receiver. Without severe symptoms, people like the elderly or others with health issues could gain immunity without risking their lives. Therefore, making vaccines should be the main plan to stop coronavirus, not herd immunity.
The public should not wait on vaccines when immunity can be achieved now. Vaccines take time to make. Scientists need to isolate the genes of the virus, develop a test ready solution, and use it on a large number of individuals. All of that takes time. If the first round of tests fail, the the scientists have to start over again. While they are developing a vaccine, it would be best to get as many people immune as possible.
[P1] Vaccines prevent illnesses and stop the spread of infection. [P2] Vaccines don’t have the same severe symptoms like the virus it’s imitating. [P3] Without the severe symptoms, the elderly and disabled can benefit from vaccines. [P4] Natural herd immunity would have to be an ineffective main source of prevention if there is no vaccine.
Rejecting the premises
[Rejecting P1] Some viruses don’t have a vaccine. [Rejecting P4] Herd immunity has worked well in the past.
