      As bacteria and viruses can evolve and adapt, so it is not possible to create a vaccine that will work

      The biggest problem is the variation in the virus you are trying to target. Virus’s will change with the host so its really difficult to have a one vaccines fits all approach…

      Scientists are working hard to find vaccines for many diseases but as Andy and Duane have mentioned…..viruses and bacteria are changing and evolving all the time….even the viruses which cause influenza are slightly different every year…and even if we had flu last year and build our own vaccine…or immunity….we have good chances to get flu this year again…..not fair!!!
