No, I think it would be similar. Biologics or vaccines, as a rule, may not have quite as exhaustive mechanistic studies because, again, you're not putting anything in their system, such as a chemical; you're just stimulating the immune system to put up its natural defences against a germ, so the cost of developing a vaccine is slightly less than that of a drug. But you're absolutely correct on the timeframe.
