US-based coverage reports that a medical study finds higher rates of bleeding in infants associated with more parents declining vitamin K shots at birth. The reports emphasize that vitamin K deficiency can lead to potentially serious bleeding, prompting guidance that newborns receive the shot to reduce risk.

Several outlets place the findings in a broader context of changing parental behavior since the start of the COVID-19 pandemic. They describe that refusals appear to have increased over time, and at least one outlet says the acceleration has occurred more recently. Coverage focuses on the study’s link between non-receipt of the shot and bleeding incidents, while also drawing attention to prevention through vaccination at birth.
