At least two newspapers carry reports about the study on Saturday, the Chinese “South China Morning Post” and specialized “Journal of Virology”.

In the scientific middle had praise for the study, but also cautions because still be necessary wait to see if the discovery will lead to a vaccine’s reliable and commercially viable, said Dr Guan Yi from University of Hong Kong.
Zhou admitted the long effort of analysis and verification of results that have ahead the institutes that hold the samples. To illustrate the challenge size he compared with “finding a needle in the seabed of the Pacific”. This all, with aggravating factor that validity of blood samples for research expire after a few days, so the race against the clock.
At December 31th, a bus driver died after contracting the H5N1 virus, the first death in a year and half in the country by Avian Influenza.
