[Consideration on the usage of full-dose influenza vaccine for the infants aged 6-35 months old].

Seasonal influenza has a high disease burden, and children infected with influenza are prone to multiple complications. Influenza vaccination is effective in preventing infection and reducing risks of severe diseases and complications. Influenza vaccines are trivalent and quadrivalent, depending on the components of the vaccine. According to the hemagglutinin content, it can be divided into full dose and half dose of influenza vaccine for children. The findings from clinical trials and real-world studies suggested, the full-dose influenza vaccine as in adults has the same safety profile and higher immunogenicity in children aged 6 to 35 months. The application of full-dose influenza vaccine in children aged 6 to 35 months can greatly improve the flexibility and convenience of vaccination, and help reduce the workload in the process.
