RNA vaccination in rabbit mothers confers benefits to offspring in the womb, shows study

Newly developed mRNA vaccines against Zika virus and HIV-1 produced strong antibody responses that transferred from pregnant rabbits to their offspring, researchers report in the journal Molecular Therapy. As noted by the authors, the results support further development of their vaccine platform, LION/repRNA, for maternal and neonatal settings to protect against mother-to-child transmission of pathogens in animals and humans.
