Vaccine issues need to be treated with a more open scientific attitude

No matter what kind of drug or how safe animal tests are, after large-scale use in humans, various problems will always arise, including vaccines. It can be said that if the vaccine is safe and has no side effects under the vaccination of 3 billion doses, either the vaccination may only be normal saline, or there is a problem with this "safe" data.

Because from the current vaccine history and the global vaccine situation, even some of our very mature vaccines that have been in use will still have some post-vaccination side effects and adverse events after use. The problem of probability is high or low, but the problem of no problem itself is a pseudo-proposition, and there may be no problem in itself, which may be the biggest problem.

Therefore, at present, the toxicity of the virus has evolved in a weaker and weaker direction, and the emergency use of vaccines is also to deal with the virus at the stage of toxicity and harm. Whether it is necessary to continue large-scale vaccination at this stage? It may be an issue that requires scientific evaluation and consideration. And for vaccines, whether it is necessary for us to continue to adopt the lenient approval process for emergency use is also a current issue that needs to be re-examined.

As for the vaccination, maybe we still have two things to make up: one is some side effects and adverse reactions that may exist after the previous vaccination. This issue is very necessary to carry out a serious review, after all, it involves all the people health issues.

The other is to treat the objective issue of vaccines with a more open scientific attitude, that is, the possible side effects and adverse reactions of vaccines, allow and encourage more independent institutions, experts, and media to intervene in tracking and reporting, and allow the society to participate in feedback issues and supervision, in order to better promote the development of our country's biomedical industry.
