Documents from Moderna’s COVID-19 vaccine trial on animals show that some of the offspring of rats that were injected with the company’s mRNA shot developed rib malformations.

The documents total 700 pages and contain a portion of the formal biologics license application (BLA) package that Moderna had submitted to the Food and Drug Administration (FDA) for approval of its SpikeVax mRNA vaccine.
