previous infections. Immunological memory can develop from multiple branches of the …

Understanding the causes of the diverse outcome of COVID-19 pandemic in different
geographical locations is important for the worldwide vaccine implementation and pandemic …

BACKGROUND Immunization against SARS-CoV-2, the causative agent of COVID-19,
occurs via natural infection or vaccination. However, it is currently unknown how long …

Understanding which arms of the immune response are responsible for protection against
SARS-CoV-2 infection is key to predicting long-term immunity and to inform vaccine design …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection of vaccinated
individuals is increasingly common but rarely results in severe disease, likely due to the …

Adaptive immune responses to SARS-CoV-2 infection have been extensively characterized
in blood; however, most functions of protective immunity must be accomplished in tissues …

Information concerning the longevity of immunity to SARS-CoV-2 following natural infection
may have considerable implications for durability of immunity induced by vaccines. Here, we …
