ABSTRACT
Objective: We investigated whether there was a difference in the antibody profile after Pfizer/BioNtech vaccination in persons who had already been infected with COVID-19 and those who had not. Method: Blood samples were obtained before, after the first dose and after the second dose of Pfizer/BioNtech vaccine inoculation in 4 subjects with a history of COVID-19 infection and 62 subjects without a history of COVID-19 infection after obtaining their informed consent. The differences in the antibody titers were examined between those with and without a prior history of COVID-19. Result: As compared with those without a prior history of COVID-19, those with a prior history of COVID-19 showed significantly higher antibody titers after the first inoculation, and the antibody titers were significantly higher than even those after the second inoculation of subjects without a prior history of COVID-19.
ABSTRACT
The appearance of the Covid-19 since the beginning of the year 2020 has involved changes in many aspects of daily life in the world. Thus, it has impacted the university in its three dimensions: humanistic, research, and interaction with the company and the community. Particularly in teaching that has varied substantially. In this context, the teaching, and results in courses in some Peruvian universities will be compared during the 2019-2 semesters (eminently face-to-face) and the 2020-1 semester (necessarily virtual). The results and their analysis lead to a proposal of pedagogical innovations in teaching and its extrapolation to the research and interaction of the university with companies and communities. © 2021 Latin American and Caribbean Consortium of Engineering Institutions.
