At the nucleic acid sampling point of Tongtongxiang Community in Xi'an City, the staff sampled throat swabs for the masses. At the Zhongda Hospital affiliated to Southeast University, the staff showed the negative results of COVID-19 antigen test. In the coming 2022, human beings have been tenaciously fighting against COVID-19. At the same time, the antigen detection extract contains highly toxic explosives, the nucleic acid sampling swab contains carcinogens, and the long-term wearing of masks can cause lung nodules to increase... These rumors related to COVID-19 keep emerging, confusing our understanding and becoming a stumbling block on the way to fight the epidemic. Although it is impossible to eliminate COVID-19 with human power at present, we should strengthen our resistance to rumors as we strengthen our resistance to viruses. We should not follow the crowd, listen to partiality, restore the truth with science and reason, and smash rumors. In the future, we will vigorously spread scientific spirit, scientific thinking and scientific methods, and strive to improve the scientific literacy of the whole people to build a more solid barrier against rumors. The virus has been mutating, but vaccination is useless? Vaccines are not useless, but basic immune barriers can be established from Delta, Ramda to Omikjon... In the past three years, the cunning COVID-19 has changed its "waistcoat" again and again, which has also increased the difficulty of epidemic prevention. Many people think that the current COVID-19 vaccine is only for the current popular COVID-19, and the vaccine will be useless after virus mutation. In this regard, Shao Yiming, a researcher from the Chinese Center for Disease Control and Prevention and a consultant from the World Health Organization's Vaccine Research and Development Committee, made it clear in an interview with the media that COVID-19 Vaccine would not go unpunished. Shao Yiming said that the level of neutralizing antibody induced by COVID-19 vaccine may decline in front of COVID-19 mutants, that is, the protective effect of the vaccine may decline. However, as long as the vaccine is inoculated, the COVID-19 vaccine will build the basic immunity against COVID-19 for the vaccinators. Even if the ability of the virus mutant to escape the protective barrier of the vaccine becomes stronger, a new mutant vaccine can still be used as a booster. In this way, the booster needle can quickly stimulate the immune protection of the human body against the mutant virus on the basis of the existing immunity. In addition, according to media reports, a research report once released by the Butantan Institute of Sao Paulo, Brazil, showed that the Kerraf COVID-19 vaccine jointly developed by China and Brazil can effectively fight against the mutated COVID-19 in Brazil, the United Kingdom and South Africa. The researchers extracted the serum from the vaccinated volunteers and put it into the culture dish together with the mutant virus. The results showed that the antibody in the serum could effectively fight against the mutant virus. In addition, according to the information once released by the World Health Organization, from the global monitoring of COVID-19 mutation, there is no evidence that the existing COVID-19 vaccine will become invalid in front of the virus mutation. Morning "Yang" Good morning? There will be no lifelong immunity after infection, and protection is needed in the near future. With the adjustment of epidemic prevention and control policies, the number of COVID-19 infected people is gradually increasing. "Respecting the first sun", "Good morning sun" and other comments have become high-frequency words in social media. Some netizens said that one infection is equivalent to one vaccination. It is better to have a good morning "Yang" than to worry about whether you are "Yang" every day. Zhang Boli, academician of the CAE Member, said that at this stage, we still need to do a good job
