The following is an excerpt.
A copy of the genetic code of an H7N9 avian flu—similar to, but not exactly the same as the flu that has killed 36 people in China—arrived in a lab in Boston Easter Sunday, 2011. By Saturday, scientists had made a vaccine against it, the Boston Globe reported.
That turnaround time is weeks faster than the current best vaccine-making methods. The new shot-making strategy still needs to undergo approval from the U.S. Food and Drug Administration. It also needs tweaking before it would able to make the large amounts of vaccine needed during a flu outbreak, the editors of the journal Science wrote in a summary of the work. If the method does make it to market, however, it could speed the response to flu pandemics.
