YI Jointly Protecting Seedlings: A Heavy Responsibility and a Long Journey Ahead
April 25, 2018 marked China’s 32nd National Children’s Vaccination Publicity Day. With the deepening of public awareness campaigns, vaccination efforts have achieved significant progress and remarkable results in recent years.

Speech by Zhang Hongping, Head of the Health Culture Promotion Platform of the National Health Commission
Director Zhang Hongping stated in her speech at the event that vaccination has always been one of the most cost-effective and efficient measures for the prevention and control of infectious diseases. The new challenges in the new era have also put forward new requirements for immunization program work. Strengthening immunization program work largely depends on improving public health literacy. Therefore, in vaccination work, greater attention should be paid to vigorously carrying out publicity, strengthening health promotion and health education, popularizing knowledge about immunization program policies, vaccination, and vaccines. By adopting forms that are popular among the public, scientific information can be effectively conveyed to them, enabling the public to understand immunization program policies, become familiar with immunization schedules, and enhance their trust, acceptance, participation, and sense of benefit regarding vaccination.
Prior to the 19th century, vaccines did not exist, and viruses ravaged human lives with impunity. The advent of vaccines has saved tens of millions of lives, enabling humanity to eradicate smallpox, subdue cholera, and control various other diseases, including pertussis, diphtheria, tetanus, and poliomyelitis.

Chen Honglin, Assistant to the General Manager of Shenzhen Sandairen Technology Co., Ltd. and Operations Director of Xiao Dou Miao, Delivers a Speech
“We hope this event will draw greater public attention to vaccines and foster a scientific understanding of vaccination, which was our original intention in organizing it,” said Chen Honglin, Assistant General Manager of Sandairen Technology and Operations Director of Xiao Dou Miao. “At the same time, we believe that science communication is not something that can be achieved overnight. For nearly four years, Xiao Dou Miao has been committed to disseminating knowledge about childhood immunization in a professional, engaging, and accessible manner, building the most professional and authoritative vaccine knowledge base. To date, the cumulative number of views for our educational content on the platform has reached 123 million.”
It is understood that, in addition to providing vaccine-related science education and consultation services, the Xiao Dou Miao app offers a comprehensive suite of features covering the entire vaccination process. These include electronic vaccination record inquiries, appointment reminders, inventory checks, scheduling, and payment options, thereby facilitating childhood immunizations. With over ten million users to date, it has become China’s largest platform for pediatric preventive vaccination services.
In addition, Xiao Dou Miao will release the "2018 White Paper on Vaccination Behaviors and Attitudes of Chinese Parents" on April 25. This report is based on survey responses from 290,000 parents and over 12.3 million user behavior data points. The report indicates that nearly half of infants experience delays in vaccination, and a small proportion of children have missed doses. Parents exhibit cognitive biases regarding vaccine safety, efficacy, and scientifically recommended vaccination schedules, highlighting an urgent need to improve their knowledge about vaccines.
Chen Honglin stated, “As the most widely covered, largest, and most professional national Internet+ vaccination service platform in China, Xiaodoumiao will continue to strive to improve its products while organizing such public welfare science popularization activities, aiming to provide better vaccination services for more children and parents.”

Creative short videos themed “Life Without Vaccines” were continuously screened at the event, leveraging diverse and engaging science communication content to spark public attention and discussion on vaccines and vaccination.
The event also featured a variety of interactive educational activities, including a prize-winning quiz on vaccination knowledge and a graffiti wall. Several experts were invited to address parents’ questions about vaccine inoculation, ensuring that both children and parents gained engaging yet professional insights into vaccination. On the day of the event, Xiao Dou Miao distributed over 2,700 copies of science popularization materials to the public free of charge. Furthermore, the event was live-streamed on the Xiao Dou Miao app and its WeChat official account, with an estimated reach of 15 million people, aiming to mobilize society at large to pay attention to and participate in vaccination efforts.
