I am sorry, but I must say your are not talking sense. Viruses mutate all the time and which strains of mutants will become dominant depends on the selection pressure and the replicative fitness of the mutants. If you read the paper carefully, the hypermutation is one way to kill of the virus! The YMDD mutants caused by Lamivudine survive and flourish because they are resistant to Lamivudine. This is not unexpected, that is why other antivirals were developed. Since you do research on HIV, you should know the HIV virus mutates frequently and the ones that are resistant to the drug being used survive and flourish. This leads to the concept of using a cocktail of drugs to combat this problem. In the case of HBV, we are lucky we have two drugs with a high genetic barrier for the hbv viruses to overcome before they become resistant to these drugs. The same problem happens in the world of bacterial infection and antibiotics. So to claim that we must avoid mutation is nonsensical, it is unavoidable, instead we must adopt practices that will minimize the problem - in the case of HBV, this means using drugs with the highest resistance profile.
