Core Viewpoint - The 100th anniversary of Gu Fangzhou's birth has been officially included in UNESCO's commemorative activities, highlighting his significant contributions to public health through the development of the oral polio vaccine, which has protected millions of children from poliomyelitis [1][20]. Group 1: Historical Context - In 1955, a large outbreak of poliomyelitis occurred in Jiangsu, quickly spreading to other cities, posing a severe threat to children under seven years old [3]. - Gu Fangzhou was tasked with developing a vaccine in 1957, marking the beginning of his lifelong commitment to combating poliomyelitis [5]. Group 2: Vaccine Development Process - In 1959, Gu Fangzhou and his team learned vaccine production techniques in the Soviet Union and returned to China to begin experimental production [7][8]. - Gu Fangzhou personally tested the vaccine and even used his own son as the first child subject in the trials, demonstrating his commitment to ensuring the vaccine's safety [10][12]. Group 3: Impact and Achievements - The first batch of 500 million doses of the vaccine was produced in December 1960, significantly reducing the incidence of poliomyelitis in China [12]. - By 2000, China was officially recognized as a polio-free country, marking a significant public health achievement [16]. Group 4: Legacy - Gu Fangzhou's innovative approach to vaccine formulation, including the creation of the sugar-coated vaccine, has left a lasting legacy in public health [13]. - His story and contributions have transcended national borders, becoming a shared human legacy recognized by UNESCO [20].

Core Viewpoint - The 100th anniversary of Gu Fangzhou's birth has been officially included in UNESCO's commemorative activities, highlighting his significant contributions to public health through the development of the oral polio vaccine [1][18]. Group 1: Commemoration and Recognition - The anniversary activities will be jointly held in China, France, and Italy during 2026-2027, marking another successful application by China for a scientist's anniversary event at UNESCO [1]. - Gu Fangzhou, affectionately known as "Sugar Pill Grandpa," is celebrated for his dedication to developing a vaccine that protected millions of children from polio [1][18]. Group 2: Historical Context of Polio Outbreak - In the summer of 1955, a severe outbreak of poliomyelitis occurred in Jiangsu, quickly spreading to other cities, posing a significant threat to children under seven [3]. - The only preventive measure against polio at that time was the development of a vaccine, which Gu Fangzhou was tasked with creating in 1957 [5]. Group 3: Vaccine Development Process - Gu Fangzhou and his team were sent to the Soviet Union in 1959 to learn about polio vaccine production, facing numerous challenges due to the lack of knowledge about the disease [7]. - By the end of 1959, they had mastered the technology for producing a live attenuated polio vaccine and began experimental production in China [8]. Group 4: Safety Trials and Innovations - Gu Fangzhou personally tested the vaccine and even used his own son as the first child subject in the trials, demonstrating his commitment to ensuring the vaccine's safety [10]. - The first batch of 5 million doses was successfully produced in December 1960, significantly reducing the incidence of polio in China [12]. Group 5: Long-term Impact and Legacy - The innovative approach of creating a solid form of the vaccine, akin to traditional Chinese medicine, allowed for widespread distribution and led to a dramatic decrease in polio cases [12]. - China was declared polio-free in 2000, marking a significant public health achievement and solidifying Gu Fangzhou's legacy in the field [14]. - Gu Fangzhou's contributions have transcended national boundaries, with his scientific spirit and dedication to public health recognized globally [18].
