BEIJING, April 2 (Xinhua) --

China's food and drug regulators on Wednesday authorized a domestic pharmaceutical firm to begin commercial production of a human bird flu vaccine, following more than two years of clinical trials.

The firm, Beijing-based Sinovac Biotech Co., Ltd. will produce vaccines to defend humans against the H5N1 virus and its epidemic variety.

According to Yin Weidong, general manager of the firm, Sinovac has the ability to produce new vaccines even if the virus mutates in humans.

China started clinical research and experiments as part of the process of making a vaccine in November 2005, after a domestic epidemic that caused huge losses for poultry breeders.

Since 2005, there have been 29 human cases reported, according to the Chinese Center for Disease Control and Prevention.

□□□□(Reporter Cai people intern Liu Si? Report Huang Sui) yesterday, the first session "the French medicine date" the tour speech held in Guangzhou, more than 300 health, the medical worker attended the French infectious disease to prevent and control expert Professor Bai Likai and Professor Bourdillon's course. At the meeting, Professor Bai pointed out, although the birds and beasts flu epidemic situation already was under the active control, but the flu high prevalence still as necessary possibly occurs.

□□□□"each period of time, the flu virus can in a disorderly way appear the big variation, produces one kind of new virus, but this kind of virus has the possibility to become the flu high prevalence chief criminal very much." Professor Bai analyzes that, this kind of situation does not lack the precedent, on the century has had 4 high prevalence, respectively was in 1918, in 1957, in 1968, in 1977. On present range high prevalence already quite long, erupts the high prevalence probability unceasingly to increase, although did not know when the flu high prevalence occurs, but may firmly be high prevalence certainly can erupt. "High prevalence very greatly possibly (birds and beasts flu virus) or A (armor) the viral variety causes by H5N1." Professor Bai believed, although only has the interpersonal dissemination to be able to initiate high prevalence, now the birds and beasts flu virus cannot interpersonally disseminate, but humanity's direct contact infection birds and beasts flu accidental case of illness which discovered in Hong Kong starts from 1997, already a `14 country occurred the humanity infected case of illness, the birds and beasts flu virus danger coefficient unceasingly is increasing.

□□□□Professor Bai indicated, although may affirm the big class guild erupts, but the present does not have any means to forecast how the sudden change virus can be as well as the viral toxic strong and the weak, the propagation velocity speed, the dissemination horizontal height and so on. These at present all or the question and the guess, regarding the new virus, the existing medicine effect also possibly is at a loss, only can complete the early warning preventing and controlling measure in advance. "The flu can cause has a fever, the dissemination ache, the headache, the cough, the breath is impeded. The new virus possibly also can initiate the digestion not to be good, the diarrhea or the nerve symptom and so on, and what is more has the breath failure, the existing medicine displayed the effect to the seasonal flu, regarding viral variety effect how, but also knew without knowing where to begin, now only can from prevent and control in advance begins."

□□□□in history 4 big flu

□□□□from 1918 to 1920, "the Spanish flu", the cause of disease was the H1N1 virus, this flu altogether had 1 billion people to infect, this flu high prevalence characteristic was, in 20 ~ 50 year-old adult the disease incidence rate and the mortality rate were highest.

□□□□in 1957 "Asian flu" and in 1968 "Hong Kong flu" eruption popular period, various age groups easy feeling, the mortality rate to elevate, above 65 years old the senior citizen especially is remarkable.

□□□□in November, 1977 ~ in January, 1978 appeared "the Russian flu" in Soviet Union to be popular, initiates this flu popular pathogenesis virus is in 1950 popular H1N1 virus changes the foreign body. Therefore, has lived in this viral class departure date the person, namely was born in 1957 ago person, appeared an armor flu virus H1N1 virus infection regarding 1,977 ~ in 1978 to have the immunity and the resistivity once more. So far, the armor virus which evolves by 1977 viral (H1N1) with the armor virus which produced from in 1968 popular (H3N2) already the popular more than 20 years, moreover still was causing the flu to be popular.
