Vaccines work by educating the host’s immune system to recall the identity of a virus years after the initial encounter, a phenomenon called immune memory. Viral vaccines establish immunity and memory without the pathogenic consequences typical of a natural infection. The success of immunization in stimulating long-lived immune memory is among humanity’s greatest scientific and …

TWiV 677: Does antibody really know what time it is? Read More »
Immunologist Shane Crotty joins TWiV to discuss the antibody and T cell responses to infection with SARS-CoV-2, followed by answers to listener questions.
With the looming prospect of mass immunization against influenza, it’s important to understand how vaccines work. To do this we must have a good understanding of adaptive immune defenses. Today we’ll begin a discussion of the humoral arm of the adaptive immune response – antibodies. Antibodies are large proteins produced by vertebrates that play important …
The immune response to viral infection comprises innate and adaptive defenses. The innate response, which we have discussed previously, functions continuously in a normal host without exposure to any virus. Most viral infections are controlled by the innate immune system. However, if viral replication outpaces innate defenses, the adaptive response must be mobilized. The adaptive …
