Scientists present the latest research on the immune response against SARS-CoV-2, the influence of COVID-19 on future vaccine responses, and drivers of T cell development.

Pregnancy-induced changes in the immune system are key to a successful birth. Understanding those changes could allow researchers to protect both mother and child.
Researchers say they’re abandoning the project in its current form—one of several that aims to induce what’s known as mucosal immunity against SARS-CoV-2.
A vaccine strategy involving formulation changes, an initial escalating dose, and a longer wait for booster immunization results in more-effective antibody production against HIV in rhesus monkeys, a study finds.
Thenewly authorized intradermal vaccination only requires one-fifth of the usual vaccine dose. This will help stretch out the limited vaccine supply, experts say, but only if healthcare personnel receive sufficient training.
For the first time, researchers performed a head-to head longitudinal study comparing the immune response elicited by mRNA and traditional COVID-19 vaccines to primary infections.

Compared to mice who got the doses in separate limbs, animals receiving flu shots in the same paw for both a first and second dose had better-trained memory B cells that bound tighter to the vaccine antigen.
Use of the drugs in children under the age of two was associated with lower antibody levels after the jabs—perhaps, researchers suggest, due to microbiome alterations.
