E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the effectiveness of an A(H1N1)v influenza vaccination in preventing the first episode of laboratory-confirmed infection with the novel, pandemic influenza A(H1N1)v virus among community-dwelling and recently vaccinated adults as compared to unvaccinated adults from a cohort of at least 4,000 persons |
|
E.2.2 | Secondary objectives of the trial |
• To assess the safety for 6 months after vaccination with the A(H1N1)v vaccine during the follow up; • To determine humoral and cellular immune responses to one or two doses of the A(H1N1)v vaccine in 200 adults aged 18 to 75 years • To evaluate the incidence, severity and possible complications of laboratory-confirmed infection with the novel A(H1N1)v influenza virus; • To explore the effectiveness of the A(H1N1)v vaccine in subgroups stratified by age • To study the narcolepsy associated risk and protective HLA genotypes in the subgroup of the individuals in whom the immune responses to A(H1N1)v vaccine are studied (immunogenicity cohort) and to evaluate the effect of these genotypes on the characteristics of immune responses to to A(H1N1)v vaccine • To explore the systemic inflammatory responses induced by A(H1N1)v vaccine in the follow-up serum samples from the individuals of the immunogenicity cohort

Substudy 1. A(H1N1)v-immunogeenisuustutkimus : included in the main protocol V1.0, 27.8.2009; the immunogenicity cohort. Objective: to determine humoral and cellular immune responses to one or two doses of the A(H1N1)v vaccine in 200 adults aged 18 to 75 years.
Substudy 2. A(H1N1)v-rokote ja tulehdusreaktio : included in the Amendment 1, version 2, 23.9.2010 of the main protocol. Objectives: 1) To study the narcolepsy associated risk and protective HLA genotypes in the subgroup of the individuals in whom the immune responses to A(H1N1)v vaccine are studied (immunogenicity cohort) and to evaluate the effect of these genotypes on the characteristics of immune responses to to A(H1N1)v vaccine. 2) To explore the systemic inflammatory responses induced by A(H1N1)v vaccine in the follow-up serum samples from the individuals of the immunogenicity cohort |
