INFO-VAC: Healthcare Professionals
Instituto Gulbenkian de Ciência and Centro Hospitalar Lisboa Ocidental, E.P.E. have been collaborating on SARS-CoV-2 virus surveillance projects in healthcare workers, namely in what concerns the study of vaccine effectiveness, of which the results of the first and second phases of the study are known. The study is ongoing and will follow the group of 1250 healthcare workers for a period of one year, as this is the only way to understand how long the antibodies are maintained and if any of the study members contract the disease, what is the answer that will trigger.

Results of the 1st phase of the study
First results reveal that 90% develop immunity after taking the first dose.

Results of the 2nd phase of the study
Results lead to recommend not to increase the interval between doses and to maintain individual protection care even after the vaccination process.

Vaccine mixing study results
Immunological response data in mixed vaccination schemes reveal significant differences after six months.
