INFLUENZA G1 mHA

An AE was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. Solicited local AEs were used to assess the reactogenicity of the study vaccine and were pre-defined local (injection site) AEs for which participants were specifically questioned and which were noted by participants in a diary for 7 days post vaccination (day of vaccination and the subsequent 7 days). Solicited local AEs included injection site pain/tenderness, erythema, and swelling at the vaccination site.

AE: any untoward medical occurrence in clinical study participant administered a medicinal (investigational or non-investigational) product. AE does not necessarily have a causal relationship with intervention. Solicited local AEs used to assess reactogenicity of vaccine. Pre-defined local AEs (pain/tenderness, erythema and swelling at injection site) were noted by participants in a diary for 7 days post vaccination (day of vaccination and subsequent 7 days). Severity was assessed using food and drug administration (FDA) toxicity grading scale- Pain: Grade (G) 1 (mild; does not interfere with activity); G2 (moderate; requires modification in activity/use of medications); G3 (severe; inability to do usual activities/use of narcotic pain reliever); G4 (life threatening; hospitalization), Erythema and swelling: G 1 (mild; 25 -50 millimeter \[mm\]); G2 (moderate; 51 -100 mm); G3 (severe; greater than \[\>\] 100 mm); G4 (life threatening; hospitalization/necrosis or exfoliative dermatitis).
