Here's an article about how quickly scientists are working on a vaccine for the new virus.

I almost had to laugh when I read about the efforts to develop a vaccine, because while the mortality rate from influenza is around 1.5%, only half of Americans even bother to get a flu vaccine. Believe what you want, the last time I had the flu was almost 35 years ago. I've gotten my flu vaccine every year since. So, I believe tha, the flu vaccine is usually very effective, but a high percentage of people would rather risk being sick or dying. Plus, even those who get the flu after being vaccinated, almost always have a milder case.
A CDC doctor that I saw on the news two days ago, said that it appeared as if the mortality rate for this new virus was likely to be about 3%, but people are acting like it's 90%, My neighbor said she saw three people in the grocery store wearing masks. yesterday.
Most of the people who have been infected are recovering. Considering the shortage of medical supplies and lack of adequate hospital care, as well as the over crowded conditions in China, I think there's a lot of overreacting going on in the first world countries.
