Summary

A study reviewing 1,500 research papers found that 90% of pregnant women who contract bird flu (H5N1) die, with 87% of their unborn babies also dying.

Most surviving babies are born prematurely.

While human cases are rare and usually result from direct contact with infected birds, the findings highlight the vulnerability of pregnant women, who often face exclusion from vaccine trials and public health programs.

Experts stress the need for pandemic preparedness and ethical studies on vaccine safety in pregnant women as H5N1 continues to spread globally.
