first: you have to see if you can develop an antigen like the ones on the virus
second: you need to test this to see if the body actually develops antibodies to this antigen AND those antibodies prevent the virus from replicating
third: you have to make sure that the vaccine does not trigger an immune response to is detrimental to the host
Finally: develop a way to make large amounts of the vaccine
One other thing.... we do not know if this virus is stable (like polio) or drifts (like the flu). If it drifts, then this years vaccine may not work next year.
