Some people are in favor of vaccination, while others are against it. Those hesitant centrists have become the focus of contention, courtship and influence between the two sides. Which school has a strong propaganda, a large volume of advertising, then which school may have more advantages. This group, known as the “anti vaccine” group, suddenly came to the spotlight against the background of the new global epidemic. The number of people was small and they were very noisy. < / P > < p > < p > “anti vaccine” groups continue to create new websites, occupy the Facebook group, and even take the cultural route, shooting videos and movies to spread false information about vaccines, especially strengthening the long-standing view that “vaccines can lead to autism”. There is a view from foreign media that the anti isolation protests across the country have become a fertile ground for anti vaccine activists, indicating that the government led efforts to implement vaccines in the future will be paralyzed. The reason for this view is that it is observed that the two movements help each other and become angry with each other. Who will suffer without vaccination? According to the report, more than 90% of the children in the small community of Minnesota were vaccinated directly in the United States, and the vaccination rate of more than 90% of the children in the small community in Minnesota fell from more than 90% in 2008. < / P > < p > the anti vaccine campaign spreads the misconception that vaccines can lead to other diseases. Even the “anti vaccine” group launched a campaign calling on President chuangjianguo to fire Dr. Anthony Fauci, the government’s top infectious disease expert. < p > < p > Facebook in the United States also took a positive attitude and began to clean up the anti vaccine related information. On October 13, 2020, a new global policy was introduced to ban advertising “dissuading people from getting vaccinated.”. < / P > “we don’t want to get vaccinated on Facebook. ——Facebook: no advertising for vaccines. “. < p > < p > Facebook has more than 3 billion active users worldwide. Facebook has long said it wants to encourage the flow of words, but public health organizations and other critics have urged Facebook to eliminate misinformation on its platform, especially mass flooding and pervasive information. < p > < p > on the afternoon of October 13, 2020, Aleksandra Kuzmanovic, social media manager of the World Health Organization, said: “reliable information is important for obtaining vaccines that are safe and effective. We welcome Facebook’s update of its vaccine advertising policy to ban advertising that discourages people from getting vaccinated. ” < / P > < p > also said: “our goal is to help spread information about the safety and effectiveness of vaccines to a wide range of people, while banning advertisements with misinformation that may harm public health work. Now, if the advertisement specifically forbids someone to be vaccinated, we will reject it. < / P > < p > however, we still allow advertising that supports or opposes legislation or government policies regarding vaccines, including new vaccines. We will continue to require that all those who put in these ads must be authorized, and that the payer of the advertising fee should be informed in a conspicuous position so that people can see who is behind the advertisement. < / P > < p > we regularly refine our approach around advertising related to social issues to capture debates, discussions and public opinion about sensitive topics that occur on Facebook. While we can narrow the scope of law enforcement in some areas, we can expand it in other areas. ” < p > < p > in 2020, Facebook cracked down on scams and false reports about the new coronavirus, and banned vaccine misinformation and pranks discovered by global health organizations such as the World Health Organization and the Centers for Disease Control and prevention. < / P > < p > Facebook’s attitude is “we do not allow advertising to be publicly labeled as a vaccine scam by world’s leading health organizations, such as the World Health Organization and the Centers for Disease Control and prevention of the United States.” In addition to the company’s “explicitly banned” advertising to dissuade people from getting vaccinated, it also announced a new coronavirus vaccine campaign. < / P > < p > the ban also applies only to paid advertising, not to a much larger number of regular posts, discussions, comments and likes, including users with a large number of fans and posts posted in private groups with a flood of vaccine misinformation. For example, WeChat prohibits WeChat advertising, but does not prohibit official account of misinformation and public talk rubbish. Renee DiResta of Stanford Internet Observatory also told NPR that this corporate policy may have a limited effect on disseminating false statements about vaccines among already skeptical groups and groups. “It’s important to prevent people from using advertising to target new audiences,” she says. But we should not expect it to upset people who are already in the rabbit hole. ” The “rabbit hole” in this sentence is a metaphor for “the narrow world view that people against vaccination have built for themselves.”. What’s worse, fake news is more eye-catching, and false or wrong information such as anti vaccine is easier for readers to click into. I believe every netizen has a deep understanding of this. < / P > < p > the new global epidemic situation has brought a lot of difficult things for Internet giants to deal with. This global problem, the epidemic situation is not limited to one region. Technology giants have to define from a broader perspective what authoritative, credible, and healthy information is.
