On October 26, the world's first recombinant novel coronavirus vaccine (type 5 adenovirus vector) officially started free vaccination in Shanghai. Shanghai citizens who have only received two shots can choose to use the inhaled new coronavirus vaccine for the third shot.
Compared with intramuscular vaccination, one of the advantages of inhaled vaccines is to reduce the pain of vaccination, which has also attracted the attention of many parents. A reporter from the People's Daily Health Client randomly interviewed several parents, all of whom said they were very concerned about inhaled vaccines.
Ms. Zheng's daughter is in the second grade of elementary school. She told the People's Daily Health Client reporter that her child has received two doses of new crown vaccine . "The children are afraid of getting the injection. If they can complete the enhanced injection without the injection, it is indeed a good choice."

At present, Shanghai only uses CanSino inhaled COVID-19 vaccine for enhanced injection (third shot) vaccination, and the vaccinated population is limited to people aged 18 and above who have completed basic immunization for 6 months.
On October 27, a staff member from a district hospital in Shanghai told the People's Daily Health Client reporter that he has indeed received many parents from consulting children with inhaled vaccines, but he is not currently allowed to make appointments for people under the age of 18.
According to Jin Dongyan, professor and virus expert at the School of Biomedicine of the University of Hong Kong, natural infection with the new coronavirus is mainly inhaled through the upper respiratory tract, so inhaled vaccines are closer to natural infection, and the stimulation of mucosa immunization to will be better than existing vaccines. But theoretically speaking, inhaled vaccines may have a poor stimulation effect on systemic humoral and cellular immunity, and are more suitable as a booster vaccine.
"Children have not been included in the vaccinated population for safety reasons. In the future, more data on the effects and side effects of this vaccine on children, the elderly and people with weak immune systems such as immunodeficiency patients are needed." Jin Dongyan said.
