From the two reports, one can draw the impression that: one is a flow has a comeback in the northern hemisphere, “second wave” of the raging; the other hand, the existing vaccine is both effective and safe means of prevention, a type H1N1 influenza can prevent controllable.
WHO published the same day influenza H1N1 flu report summarizes the situation in the past week the situation in the global influenza H1N1 influenza dynamics. Reported that, on the 25th of this month, the Global Influenza A H1N1 influenza cases diagnosed up to 44 million people, killed over 5700 people. Just these two numbers are hard to feel the flow of the Northern Hemisphere A severe degree of disease, the report data more eye-catching another one. Reported that only in the past week, North America, influenza A H1N1 influenza deaths went so far as to reach 636 people, has created a stream in April this year since the outbreak of the highest death toll from weeks! A current outbreak in North America to become the hardest hit, the past six months have been 4175 people died of the disease.
Reported that, from the situation in different parts of the northern hemisphere, can be found in a stream of unusually early in the second wave of the epidemic. In previous years, a winter’s day is the period of high incidence of influenza, while the concentration of an outbreak of influenza this year, ahead of schedule to October. In the past week, with the northern hemisphere of Europe and Asia have emerged in the case of severe surge of cases. The European region has 281 cases of severe cases, the Asia-Pacific region, more than 1000 cases of severe cases. In which Ukraine is a typical example. Last week, Ukraine for the first time in four severe cases of death, but in the western region there are more than 20 unexplained deaths. In response, Ukrainian Prime Minister Yulia Tymoshenko October 30 announced the closure of the country’s schools and cinemas, a three-week ban on public gatherings, suspend a national non-emergency situations in the movement in hopes of curbing the spread of the epidemic. This is also a flow of European countries since the outbreak of the past six months to take the most stringent precautionary measures.
The WHO report also said that the report of the southern hemisphere in the last week, only a very small number of new cases. However, the report also pointed out that, since some countries did not closely follow the implementation of a flow of the epidemic, so the actual cases of infection should be much higher than the current report, the number of people. A few days earlier the U.S. Center for Disease Control and Prevention published the findings to this statement providing circumstantial evidence. The center said that the United States infected with the A stream is estimated that between 1.8 million to 5.7 million higher than laboratory-confirmed cases of the several dozen times.
27 to 29 October, WHO is responsible for working in the field of immunization Strategic Advisory Group of Experts meeting in Geneva, the participating experts on the current global supply of Influenza A H1N1 influenza vaccine, clinical trial results, safety and other issues were discussed, and on related issues to make recommendations to the WHO report.

The report first confirmed influenza A H1N1 influenza vaccine safety. Reported that the experts study the influenza A H1N1 influenza vaccine in some populations in the early post-vaccination monitoring results found that the vaccine will not bring any unusual side effects. Although the WHO has also received some information on side effects after vaccination briefing, but these side effects and vaccination for seasonal influenza vaccine side effects are basically the same, but influenza A H1N1 influenza vaccine adverse reaction ratio and a large number of seasonal influenza vaccine The most secure type of vaccine at levels comparable. But experts also stressed that although the influenza A H1N1 influenza vaccine on the early detection results are satisfactory, but information on the monitoring of side effects should continue.
In addition, the report confirms the existing national regulatory authorities have been approved by a flow of vaccine effectiveness of high-risk groups. The epidemic situation and look at the past six months, pregnant women and young people are a high flow of the two groups. Studies have shown that patients with a flow of 7-10% in pregnant women, while younger adolescents and adults in the structure in the patient occupies the largest share. Experts say adults and 10 young people over the age of a single injection of a vaccine would enable the flow of the body immune system, and related test results does not indicate the H1N1 influenza vaccine Influenza vaccination of pregnant women would result in any direct or indirect adverse effects. These encouraging reports will provide this information to WHO, the WHO influenza prevention and control of next week will be a basis for issuing new guidelines for H1N1 influenza.
