Rapid sequencing of avian influenza virus H7N9 has allowed to evaluate the potential effectiveness of a vaccine. And the results are discouraging. If the virus became seriously dangerous outside the 60 cases and 13 deaths now officially-recognized until the vaccine can get would be ineffective, according to a study made Epivax company specializing in the application of computing to immunological processes. The result has been released by the International Society for Infectious Diseases.
In reaching this conclusion, the researchers have made rapid sequencing of the two proteins of the viral envelope which identify the H7 and N9. And after this work have identified epitopes (or epitopes) presented. This name refers to the more or less stable areas that are identified by the antibodies of the organism acting as sentinels. Unless variety and number of epitopes, the virus will most invisible to the system responsible for locating foreign bodies, mark and destroy them. In fact, true to the Anglo-American easy baptizing discoveries have already qualified as a stealth virus (stealth), the same adjective that was used for stealth bombers, so called because the radars not detected.
In his work, as seen in the picture, the company's researchers have discovered that the H7N9 has less identifying areas that the H3N2 virus that has circulated this winter (which has had some troubling peak precisely because the vaccine does not work so good), and unless the new call AH1N1 flu or influenza A.
For now, with controlled expansion (Shanghai authorities have not notified new cases and flu has fallen off the first page of the Shanghai Daily and China Daily), the urgency of the vaccine is lower, although the Control Center U.S. Disease (CDC) are working on it.
So shy, the tail of influenza have already reached Spain. The PSOE has submitted a parliamentary question on the measures. "We must be careful. Ever mutation can be effective and we will find a mess, "said the Group Health spokesman in Congress, José Martínez Olmos.
