(2022-2024; PN-III-P1-1.1, PD-2021-0825) – Principal investigator: Lilia Matei, PhD
Aim: This project aims to evaluate the persistence of anti-SARS-CoV-2 immune response developed post-infection or post-vaccination to different SARS-CoV-2 variants in order to better understanding the natural adaptive immune response to SARS-CoV-2.

Summary: Coronavirus disease 2019 (COVID-19) is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is a serious disease that has resulted in widespread global morbidity and mortality. Globally, at the beginning of July 2021, there have been more than 183 million confirmed cases of COVID-19, including almost 4 million deaths, reported to WHO. With the COVID-19 pandemic outbreak spreading worldwide, immunity to SARS-CoV-2 infection is central to long-term control of the current pandemi. The recent development of different types of vaccines (mRNA or adenoviral vector-based technology) opens new perspectives in the fight against COVID-19. Still, one of the most important question is how long humoral and cellular immunity will last and whether it will protect the population from recurrent SARS-CoV-2 infections, especially in the context of new emerging variants in the UK (B.1.1.7), South Africa (B.1.351), Brazil (P.1) and India (B.1.617). The same question applies to those who have had a natural infection with SARS-CoV-2. In this context, our project aims to evaluate the persistence of anti-SARS-CoV-2 immune response developed post-infection or post-vaccination to different SARS-CoV-2 variants in order to better understanding the natural adaptive immune response to SARS-CoV-2.
