In terms of the Fubitai vaccine, experts from the committee suggested the day before yesterday that children from 6 months old to under 5 years old should be vaccinated with the infant version of the Fubitai vaccine at a dose of only 1/10 of the adult version. If the government fails to obtain a specific formula in the short term, it can be Discuss dilution of adult formulations to appropriate doses. Cui Junming, president of the Society of Hospital Pharmacists, said yesterday morning that he had tried diluting the Fubitai vaccine and found that there was a large chance of error. He was worried that it would affect the antibody level or immune response, so it was not recommended.
Liu Yulong, chairman of the Scientific Committee on Vaccine Preventable Diseases, said that although there is no precedent for self-dilution in the world and there are certain risks, it does not mean that Hong Kong cannot try it. Zhang Zhujun, director of the Infectious Diseases Division of the Center for Health Protection, said yesterday that following consulting experts, he believed that dilution was not feasible and difficult.
Young children should be vaccinated with Fubitai
Xu Shuchang said that in the future, the first two doses of Fubitai should be vaccinated by young children at an interval of 8 weeks, and the third dose should be at least 3 months apart. He also cited research as saying that in clinical trials, no serious side effects such as myocarditis and immediate sensitivity have been seen in young children following inoculation with Fubitai. The committee also discussed whether other vaccines can be given at the same time. Xu Shuchang said that the new crown vaccine can be vaccinated on the same day as the influenza vaccine and Streptococcus pneumoniae vaccine. In addition, eligible persons aged 50 to 59 can also make an appointment for a fourth injection starting tomorrow.
