At the China International Fair for Trade in Services in 2020, the domestic COVID-19 vaccine made its first stunning appearance as the "main coffee", which was widely concerned by public opinion. With the increasing popularity of vaccines in COVID-19, the discussion about vaccines in COVID-19 has led to rumors such as "high-priced vaccines", "ineffective vaccines" and "unsafe vaccines". In this regard, I really smashed the false rumors and decrypted the COVID-19 vaccine on the China Internet joint rumor platform. Let’s take a look.
1. After Covid-19 mutates, the vaccine will be invalid?
Because Covid-19 infected people can still be reinfected after recovery, there are rumors that Covid-19 mutates too fast, so it is difficult for the vaccine to cover the mutated Covid-19, and it will not be effective.

Chen Wei, a national honorary title winner of "People’s Hero", an academician of China Academy of Engineering and a researcher at the Institute of Military Medicine of Academy of Military Sciences, responded that up to now, the recombinant COVID-19 vaccine developed in China can completely cover the mutated Covid-19.
In addition, according to the data, several subtypes are indeed mutating in Covid-19 at present, but its main gene sequence and protein level have not changed fundamentally, so it is no problem for COVID-19 inactivated vaccine to deal with these mutated viruses in the next few years.
Really: the virus mutation is not terrible, and the vaccine works.
Second, the price of vaccines in COVID-19 is too high for ordinary people to afford?

Regarding the pricing of vaccines in COVID-19, Zheng Zhongwei, director of the Science and Technology Development Center of the National Health and Wellness Commission and head of the vaccine research and development special class working group of the the State Council Joint Prevention and Control Mechanism, said that COVID-19 vaccines belong to public health products, and their pricing will not be based on the contradiction between supply and demand in the market, but on the cost.
Yin Weidong, chairman, president and CEO of Kexing Bio, also said that the price of vaccine will fluctuate due to different purchasers and different purchasing scales, but the final price will be at the level of 100 yuan, which will not exceed 1,000 yuan.
Zhenzhen: COVID-19 vaccine will be on the market, and vaccination and epidemic prevention can be expected.
Three, COVID-19 vaccine will have side effects, unsafe?
Not long ago, a false news that "Putin’s daughter died because of the side effects of injecting COVID-19 vaccine" spread wildly on the Internet, which shows that the safety and side effects of COVID-19 vaccine have always been the focus of attention.

In response to public doubts and concerns, Academician Chen Wei pointed out that the results of the first phase clinical trial of recombinant COVID-19 vaccine showed that all 108 people vaccinated produced antibodies. Phase I and phase II clinical trials have proved the effectiveness and safety of the vaccine, and phase III clinical trials will evaluate the effectiveness and safety of the vaccine on a larger scale.
It is worth noting that China officially started the emergency use of COVID-19 vaccine on July 22nd, and Beijing is the first city to start the emergency use of vaccine. At present, there is no obvious adverse reaction and no one infected with the vaccine.
Zhenzhen: The vaccine is safe and secure. Don’t let rumors disturb the prevention and control.
4. Will vaccination affect the results of nucleic acid testing?
Some netizens are worried that vaccination will have an impact on nucleic acid detection. In this regard, Zhou Song, General Counsel of China Biology of Sinopharm Group, made it clear that it would not, because the nucleic acid test detects antigens, and people produce protective antibodies after being vaccinated with COVID-19 vaccine, so the nucleic acid test will not be affected.
Really: the antigen and antibody are clearly divided, so don’t worry about vaccination.
