Health director-general Graça Freitas assured, on Friday, that "everything is prepared" for the co-administration of the two vaccines to people aged 65 and over as of today, a practice carried out in Portugal and in the world, within the scope of national vaccination programs, which aims to optimise the recommended vaccination schedules.

The DGS said that the available data analyzed by the Technical Commission on Vaccination against Covid-19, which includes the results of the World Health Organization expert group meeting on vaccination, show that there is an acceptable safety profile after taking of the two vaccines.

Furthermore, the available information suggests the maintenance of the efficacy of both vaccines, as, to date, there is no evidence of altered immune response.

The administration of the third dose of the vaccine against covid-19 is underway in Portugal, with priority being given to the elderly aged 80 and over and users of nursing homes and in long-term care, and at this stage, people aged 65 and over.
