General information about the trial
|
|||
Main objective of the trial |
- To demonstrate the non-inferiority of fractional doses of IPV administered intradermally versus full doses of IPV administered intramuscularly, in terms of seroprotection rates (polio types 1, 2 and 3) one month after the three-dose primary vaccination.
|
||
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.
