How long does it take scientists to develop a vaccine against a virus that emerged unexpectedly?


Introduction


Scientists work hard to develop vaccines against each and every viruses. When a virus out breaks scientists started researching about the virus and disease. But scientist may take too long time to develop a vaccine for certain diseases like Ebola. There are many reasons why they are unable to develop vaccines in timely manner. When a new disease starts spreading, often spreads unchecked before raising alarm. It often spread most where there health facilities not good. Like rural areas.

The process of developing vaccines


To develop a successful vaccine, scientists needs to understand the cause of the disease and what kind of virus or bacteria it is. Sometimes it is also difficult to collect the necessary samples.  But when there is an urgent need of vaccines, companies try to make vaccines and make failed drugs and make loss. To make good vaccines scientists has to do many researches. Once they get to know the cause or types of virus or bacteria they had to search for animal models to test early vaccine. Most commonly they used mammals for the testing. But sometimes they can’t use the vaccines to them because the specific animal may not have the virus at the moment. So they have to wait for log to test the vaccines.

Conclusion  

We are making progress on certain vaccines. But still it take much time to develop a good vaccine like it take more than 10 years to develop a vaccine, for Ebola and it’s a small miracle that we can get close to developing one in an emergency in less than three years. But still they can’t control the virus being spread.
