These cells are lymphocytes which, unlike B and T lymphocytes in adaptive immunity, do not need to have had previous contact with the pathogen in order to become rapidly active […]

Moderna and Pfizer-Biontech vaccines against the Delta variant in Qatar

In Qatar, the SARS-CoV-2 Alpha variant and then the Beta variant, were at the origin of two major epidemic waves at the beginning of 2021. It was later, in March, that the Delta variant was detected.
