The expert pointed out that Abdala is going through a health study that involves 120,000 subjects, and after concluding the administration of three doses to all the people in the third phase of the research, the confirmatory stage of efficacy began.

‘Based on the data obtained in the pre-clinical phase and those obtained on safety in the first and second phases of studies, as well as the preliminary results of immunogenicity collected during the trials, experts decided to move on other phases of the product’s development,’ its creators said on different occasions.
