General information about the trial
|
|||
Main objective of the trial |
• To describe the immune response of the inactivated, split-virion swine-origin A/H1N1influenza vaccine without adjuvant in each group
|
||
Protection of trial subjects |
Only subjects that met all the study inclusion and none of the exclusion criteria were randomized and vaccinated in the study. Vaccinations were performed by qualified and trained study personnel. Subjects with allergy to any of the vaccine components were not vaccinated. After vaccination, subjects were also kept under clinical observation for 30 minutes to ensure their safety. Appropriate medical equipment was also available on site in case of any immediate allergic reactions.
