The government and Hong Kong experts previously approved Kexing’s vaccination age to be lowered to 3 years old. The Hong Kong University School of Medicine team also gave intradermal Kexing vaccine to young children yesterday (21st). The youngest girl is 4 years old, said Liu Yulong, the person in charge. With reference to previous flu vaccines, the intradermal injection of antibodies was 5 times that of intramuscular injection, and he laughed and said that he would use the Japanese anime "Demon Slayer's Blade" to coax the children.

Liu Yulong, Chairman of the Scientific Committee on Vaccine Preventable Diseases and Chair Professor of the Department of Child and Adolescent Sciences of the University of Hong Kong, said on the Metro Radio program "The Avenue of Treasures" today that the team hopes to know whether intradermal injection of the vaccine will be more effective than intramuscular injection. Strong immunogenicity, refer to the same inactivation technology of influenza vaccine. "Use a 1/5 dose of intradermal injection, which is equivalent to a full dose of intramuscular injection. It is conceivable that if the full dose is knocked down intracutaneously, the antibody T cell reaction will be A lot."
He said that the youngest person who participated in the study yesterday was a 4-year-old girl, and some of them were boys between the ages of 6 and 7. He said with a smile that the team needed to play the Japanese anime "Demon Slayer", and coax the children with sweets, iPads, etc.
Liu Yulong explained that the intradermal injection requires a special needle. The needle is thinner than the hair and is inserted into the skin at an angle of 45 degrees. After the inoculation, the skin will appear slightly red and swollen after the mosquito bite, which will subside after a few days.
At present, 70% of middle school students between the ages of 12 and 17 have been vaccinated with Fubitai vaccine. Liu Yulong expects that the remaining 30% of students may be waiting for the Kexing vaccine. The bottleneck is a quick breakthrough. There will be 80% (inoculation rate for middle school students) by Christmas... preferably 95%. Hundreds of middle schools have all resumed classes without distinction."
