*Reactogenicity data were assessed using severity scales which differed before and after 1996. Only data dating from 1996 to 2007 are presented in this table except for diabetes mellitus type 1 adult patients for which data were collected in 1995. Numbers are minimal and maximal values obtained across all studies between 1996 and 2007.
**Data presented for redness in adults and in children >12 years are for reactions >20 mm in diameter and for reactions >5 mm in children <12 years.
***In adults, data for moderate and severe pain are presented. For children data for any pain are presented.
¶Fever was defined as a temperature >38·0°C in children ≥3 years, adults and the elderly and >38·5°C for children <3 years.
§Other includes malaise, fatigue, headache, myalgia and shivering.
#Whereas adults and children >36 months received a single 0.5 ml dose of the vaccine containing 15 μg of HA per strain, children 6–35 months received a 0·25ml dose of the vaccine, followed, for unprimed children, by a second 0·25 ml dose administered at least 4 weeks later.
