With a flow-confirmed cases and deaths, a sharp rise in the global prevention and control of the situation in a stream of people’s nerves taut again.
According to WHO statistics, as of now, the global mortality due to a flow of about 5,000 people. The organizations in China, said officials of October 27, this figure is likely to just “tip of the iceberg”, the actual death toll may be much higher than this. According to Chinese Ministry of Health informed that as at October 26, China’s mainland had reported 35,664 cases of Influenza A H1N1 influenza confirmed cases, 29,155 cases had been cured. Cumulative cases of severe disease, 53 patients have been cured in 17 cases, 3 deaths. October 28, released by the Beijing Municipal Health Bureau, said Beijing University of Aeronautics and Astronautics a student suffering from Influenza A H1N1 influenza deaths.
A flow of the face of increasingly severe epidemic, in addition to doing daily protection, the vaccine is no doubt the health of a sword to defend. Into October, the United States, Japan, France, Britain and other States have started the Influenza A H1N1 influenza vaccine (hereinafter referred to as a flow of vaccine) vaccination campaigns, however, the safety and efficacy of the vaccine has suffered a “crisis of confidence.” In many people want to complain do not get the vaccine inoculation, while almost as many people are challenged and refused to receive the vaccine.
Many people would not dare to vaccine
Into October, the global flow of A vaccination gradually reached its climax. Canadian media have started mass vaccination this week, the country’s history known as the largest single immunization campaigns. Germany 26, started the implementation of a nationwide vaccination campaign stream. South Korea on the 27th to start the first round of the A stream vaccination. October 21, the Beijing Municipality for the elderly and students have begun to focus on five categories of people such as free vaccination. The Government stated that, to date more than 30 million people vaccinated, plans to give 5 percent by the end of the population (65 million people) to complete vaccination. It is understood that China’s current vaccination policy is to give priority to key posts in public service personnel, students and teachers, those with chronic diseases and other key groups vaccinated.
However, the fact we wanted. It is understood that France’s vaccination campaign has started a few weeks, the Government has set up a 1080 vaccination center, but the enthusiasm of people vaccinated was not high. Many public opinion surveys show that France is willing to vaccination A vaccine in the number of streams in June of this year, Liu Cheng, fell to a four-into September, but is willing to only 26% of vaccinated health care workers. This phenomenon also appears in the U.S. health care body. In the 341 hospitals, hospitals with more than Qi Cheng vaccination rate only 37% of vaccinated health care workers reject most worried about the vaccine may cause side-effects of a stream.
“Boston Globe” The latest public opinion polls also show that more than 1 / 3 of the parents do not want their children vaccinated because of concerns there will be side effects of new vaccines. As of October 28, nearly 73000 participants of the German “Bild” online survey, 45% of people say, “wait until a better time to re-injection of the vaccine,”, 44% of people say, “refused to vaccination,” “OK Injection “and only 11%. Canada’s survey shows that 51% of people do not want vaccinations. A survey conducted by the Chinese media also showed that 2,000 respondents, more than 54% said they did not want to vaccination.
French “National Scientific Research Center” of public health and safety experts Sete Bo Mitchell, said: “France is the most willing of people vaccinated over 60 years old group, and they start from the epidemic and the most valued and protected groups in the country Therefore, infection is not serious. On the contrary, 20 years old to 40-year-old young adults in this age group is most vulnerable to virus, and may be the wishes of their vaccination is very weak. ”
Five doubts on vaccine
Then, a flow of the vaccine in the end it is desirable to play? The previous stage, “Life Times” reporter in the Information Office of the Ministry of Health and the China Center for Disease Control jointly held by the autumn of influenza prevention and control Lash interview with China Center for Disease Control immunization Planning Center Director LIANG, response Influenza H1N1 influenza joint prevention and control mechanism of the Expert Committee, Zhao Kai, head of the vaccine Academician, the Chinese Center for Disease Control experts, the new Li. Meanwhile, the journalists also connect the Chinese Medical Association, will be chairman of Respiratory Diseases, Liu Ning, to answer people’s concern.
Question one: A flow of how the safety of vaccines? In the end there any side effects? By licensed vaccines, we must first is safe. In the Phase III clinical trials, 13000 people had 21 days Efficacy results show that made the vaccine safe and effective. Some of which were adverse reactions, mainly local pain, redness and swelling, mild fever, headache, usually in 1-2 days, be eased. Up to now, have been vaccinated in the population, a total of more than 150 suspected cases reported abnormal reaction to vaccination, but many are light, and has not received reports of serious adverse reactions. WHO Resident Representative in China Lan Rui Ming said: “Global has more than 40 million cases of Influenza A H1N1 influenza confirmed cases, deaths are about 5000, but no one has died since the injected vaccine.”
Question 2: China’s vaccines is produced domestically or imported? With foreign countries any different? A stream of China’s immunization vaccines are made in China, licensed vaccines by the eight domestic enterprises. Lan Rui Ming also said that the vaccine produced in China and foreign produced no difference. A flow of the vaccine have adopted the World Health Organization recommended a flow of the virus strain, shall be subject to embryo culture, inactivated virus, purification, cracking and other processes are made. A stream of domestic vaccine production processes and seasonal influenza vaccine in previous years, basically the same.
Question 3: trying to get pregnant people can not be vaccinated? Just how long after pregnancy can be vaccinated? A stream antigens contained in vaccines, injection of the virus will stimulate a human immune response occurs to produce antibodies. For people who want to become pregnant, as long as you can not yet immunized pregnancy usually does not affect future pregnancies. Currently, however, did not advocate pregnant women vaccinated. The main reason is the lack of clinical data of vaccination of pregnant women, their risk of vaccination is still uncertain. It is learned that recently, the Ministry of Health is closely following the progress of clinical trials of the vaccine at home and abroad will be timely organization of experts, proposed strategy for vaccine for pregnant women.
