Influenza Clinical Trial
Official title:
Safety of a Single Dose (Participants Aged 9 Years and Older) or Two Doses Given 28 Days Apart (Participants Aged 6 Months to 8 Years) of the Shenzhen Quadrivalent Influenza Vaccine (Split Virion), Inactivated
This phase I-like, open-label, monocenter, descriptive, single-arm clinical safety study will investigate the Shenzhen quadrivalent influenza vaccine (Shz QIV) in 100 participants aged 6 months and older in China. Participants aged 9 years or more will receive a single dose of Shz QIV, and participants aged 6 months to 8 years will receive two doses of Shz QIV administered 28 days apart.
Healthy participants will either receive a single dose (participants 9 years or older) or two doses (participants 6 months to 8 years) of the Shz QIV. Safety in terms of serious adverse events, solicited injection site and systemic reactions, and unsolicited adverse events will be collected before and 28 days after each and any dose. ;
