Is the H1N1 vaccine safe?

Since China took the lead in developing a H1N1 flu vaccine, the sword of damaklis has been hanging: Is the H1N1 flu vaccine safe?

Influenza A (H1N1) is getting closer and closer to us. There are now more than 10 thousand confirmed cases in the Mainland. What's important is that I used to think it was just a number. Now, people around me are getting sick or trapped in epidemic areas. In addition, the second wave of autumn and winter is coming soon. Maybe in May or may, the second wave will certainly attack more people. It is not impossible for the virus to become more toxic in the second wave. According to the Ministry of Health, tens of millions of people may be infected in the second wave.

The good news is that we have vaccines, and we are the world's first. In terms of controlling the epidemic, the most reliable is the vaccine. But when I chatted with a doctor friend a few days ago, he said that he would not allow his children to take the vaccine. I asked him why, he said that, on the one hand, the stream is not so terrible, it is not worse than the seasonal flu, it can be self-healing; on the other hand, it is better to be cautious about a new vaccine.

Later, I saw Academician Zhong Nanshan in the news saying that we should be careful when launching large-scale vaccines. Indeed, in 1976, there was a flu case in a military camp in the US Army. later it was found that it was swine flu. When the Americans thought of the flu disaster in 1918, they panicked and immediately got a vaccine and 40 million people were injected. As a result, only 300 people were infected with swine flu, but 500 people experienced adverse reactions after the injection, some of which were paralyzed.

I spoke to Academician Zhong Nanshan the night before. We now have two companies that have produced a-class vaccine. We have initially observed and determined that it is safe in a security test for less than 10 thousand people. Second, it has been able to produce sufficiently high drops of antibodies. This is its positive aspect. "But I mean, because of the current security observations, there are still few objects. Now, it is prudent to treat hundreds of thousands or even millions of people nationwide ."

No vaccine is absolutely safe. Due to the lack of perennial applications, we do not know what side effects a vaccine may bring, which is disturbing. But on the other hand, it is impossible for us to waste food for some reason. The two sides share the same power, and this H1N1 vaccine is not completely new. It was developed on the basis of the past seasonal flu vaccine. There have been more than 50 years of research into influenza vaccines in China, and more than 20 years of use of influenza vaccines.

When I recorded the "Wind yanfeng Yu" program, the host Li Lei asked me in the dressing room whether there is any food without additives in the supermarket, I feel uneasy. At that time, I really didn't know how to answer her. Some additives may be problematic, and some of them are okay. If there is a problem or no problem, many of them are not clear about science. Now think about it. Life is an adventure. If you love adventure too much, you may be able to finish it. If you are not at risk, you are sure to finish it.

The results of the study are now between 0.20% and 0.68% mortality of A-flow cases. A trial of nearly 10 thousand people showed that the adverse response rate of Influenza A vaccine was lower than that of the seasonal vaccine.

Therefore, you have to make your own decisions on how to do this. Both options have to be risky, depending on how you bet. (Huang Yongming)
