Study explores differential antibody-mediated effector functions evoked by two mRNA-based COVID-19 vaccines

Researchers evaluated the differential humoral immune response to two COVID-19 vaccines - messenger ribonucleic acid (mRNA)-1273 and BNT162b2.

Pediatric adjuvant formulation offers protection against RSV in newborns

Respiratory syncytial virus (RSV) is the leading global cause of death in children under age 5 and lacks an effective vaccine. In a study from the Precision Vaccines Program at Boston Children's Hospital, a new vaccine formulation protected newborn mice against infection and evoked strong responses in immune cells from human newborns in the laboratory. Results were reported August 2 in Nature Communications.

Study finds asymptomatic SARS-CoV-2 infection induced comparable memory B cell responses to mild symptomatic infection in young adults

Researchers identified that among healthy young adults, the development of SARS-CoV-2 triggered memory B cell and antibody reactions were equivalent following mildly symptomatic or asymptomatic infections.

Incorporating a coronavirus antigen into MMR vaccine to produce COVID-19 immunity in kids

New research has advanced COVID-19 vaccine work in several ways: using a modified live attenuated mumps virus for delivery, showing that a more stable coronavirus spike protein stimulates a stronger immune response, and suggesting a dose up the nose has an advantage over a shot.
