questions to our science correspondent derek williams today comes from someone calling themselves eric cartman. how do you make a vaccine for something that mutates. i get asked this a lot to answer we have to look at the process of evolution just like with living organisms the genetic code that governs how a virus is made changes from generation to generation sometimes in small ways sometimes in big ones the progeny if they survive eventually will become separate strains that are distinct from their common ancestor their genetic code has changed and and that can change how they look at their structure and also how they interact with potential hosts for example whether they can cause more or less severe illness what's key to creating a vaccine is the speed at which these changes occur in viruses like the ones that cause influenza for example which have genomes that are less stable or the rate of change is so rapid and random that we need a new vaccine to fight them every year we have to play catch up with flu bugs all the time fortunately due to the way that sars makes copies of itself its gen
