I wonder why they're trying to create mutant variants. Perhaps it's to study how such virulent viruses mutate, with the intention of identifying the strategy that the H5N1 variant is likely to use, and thereby getting an idea of what kind of vaccine could be produced for dealing with possible outbreaks of a deadly variant.
From the little I know about viruses (and bacteria), there's been an on-going battle from time immemorial between microbes and their hosts (our immune systems versus their strategies), but the problem with virulent microbes is that they don't "care" if the host dies, so long as they can spread to the next victim before the current one ceases to provide the environment they need.
If the aim of the research is to get ahead of the game, then I'm in favour of it, but I really hope that containment is the highest priority, and that there is official/governmental oversight of those laboratories.
Is your main concern for the safety of the researchers or for the risk of escape of the mutated virus?
I think that virologists are very experienced at containment - small pox was contained for research purposes for a very long time - and so I trust their safety protocols. The disease may well mutate in the wild and we need to be prepared to tackle it so yes, from a lay person's position, I support the ongoing research.
One year ago, virologists volunteered to pause research that involved creating mutant H5N1 viruses that would be more contagious to humans than the strain(s) passing through the bird population.
Their one year moratorium is over, and they are set to begin research again. So far, over half of human beings who've tested positive for the virus have died from it. As it is, prolonged exposure and close contact are required for a person to acquire the illness, but if it were to become contagious it could rapidly become a world-wide health catastrophe.
Virologists insist that the research risks are minimal, and the benefits of the research outweigh the risks. What do you think? Should the research continue?
