By analyzing a cohort of adolescents that developed myocarditis or pericarditis after vaccination against SARS-CoV-2 vaccination, researchers from Yale University School of Medicine were able to pinpoint the underlying mechanism as an overly active innate immune response to the vaccine that led to broad activation of T cells and natural killer (NK) cells. Myocarditis “has been seen in other vaccine contexts, though is most common after viral infection,” Carrie Lucas told reporters at a press conference announcing the findings.
Multivalent vaccines that could improve SARS-CoV-2 immunity while also preventing infections by other viruses, such as influenza and respiratory syncytial viruses, constitute an urgent public health need. Currently approved vaccines against SARS-CoV-2 are based solely on the spike protein, which provides limited immunity against variations in spike.
Nanjing Zhihe Pharmaceutical Technology Co. Ltd. has described nucleotide derivatives acting as prodrugs reported to be useful for the treatment of viral infections.
Rnaimmune Inc., a nonwholly owned subsidiary of Sirnaomics Ltd., has received clearance from the FDA for its IND application to conduct a phase I trial for RV-1730, a SARS-CoV-2 vaccine booster candidate.
