Personally, that would be a use of my taxpayer dollars I would support. Face it, developing a vaccine is costly and if a bio-war breaks out, EVERYONE is going to want to be vaccinated and the government is going to step in anyway.
Can you imagine the uproar if the vaccine is privately paid for, developed/controlled and bio-war breaks out when the cost to get vaccinated is set so that the people that develop the vaccine are made whole in a business sense? What if a vaccine is developed, but production is limited because of a lack of funds? What if the cost of vaccination is $2000/dose to recover costs?
Sounds like it would be worth it. At least we would be funding someone who had come up with an effective solution.
