A recent study reveals that pregnant women who contract avian influenza, commonly known as bird flu, face a significantly higher risk of death, along with the near-total loss of their unborn babies. The findings of this research underscore the urgent need to prioritize pregnant women in public health vaccination programs, especially during pandemics.
The study, led by Murdoch Children’s Research Institute (MCRI), highlights the vulnerability of pregnant women in the event of a new pandemic caused by avian influenza strains A (H5N1 and H5N2). This systematic review, which analyzed over 1,500 research papers, examined 30 reported cases of pregnant women infected with bird flu across four countries. The results were stark, showing that 90% of pregnant women who contracted the virus died, with almost all of their babies succumbing to the illness as well. Among the very few babies who survived, 80% were born prematurely.
Urgency for Prioritization in Pandemic Planning
Dr. Rachael Purcell, a leading researcher at MCRI, emphasized the need for early inclusion of pregnant women in pandemic vaccination efforts. She stated that as human cases of avian influenza rise in both birds and mammals, there is an urgent need to recognize the unique risks posed to pregnant women. Dr. Purcell stressed that pregnant women are often excluded from vaccine trials and are typically given priority access to vaccines and therapeutics later than other high-risk populations.
The research points to the critical importance of shifting the paradigm in public health strategies. Pregnant women, who are often excluded from key aspects of pandemic preparedness, must be integrated into planning from the outset to prevent unnecessary deaths. This inclusion can be facilitated by leveraging existing surveillance systems, such as the Global Vaccine Data Network and the Vaccine Safety Datalink, as well as ensuring that vaccine trials are designed to accommodate the unique needs of pregnant women.
Global Efforts and the Need for Proactive Measures
Professor Jim Buttery of MCRI noted that during pandemics, vulnerable populations are disproportionately affected by severe disease and death. Pregnant women have faced alarmingly high death and critical illness rates during past pandemics, including those caused by influenza, SARS-CoV-2, and the Ebola virus. Proactive recognition of the risks to pregnant women, coupled with early intervention and inclusion in vaccination programs, is crucial to reducing morbidity and mortality in this high-risk group.
Dr. Buttery added that global health systems must prioritize the inclusion of pregnant women in vaccine development, monitoring, and trials. Ethical preparedness for pandemics should focus on preventing preventable deaths, which includes advancing a pregnancy-specific research agenda. This agenda can be developed in collaboration with medical review boards, regulators, and policymakers to ensure that pregnant women are not left vulnerable when the next pandemic strikes.
Australia’s Response and Global Implications
In response to the growing threat of H5N1, MCRI’s research team welcomed the Australian government’s $95 million investment in preparation efforts. Notably, Australia remains the only continent free of the deadliest strain of avian flu, highlighting the importance of proactive measures.
Researchers from the University of Melbourne, The Royal Children’s Hospital, Monash Health, and Monash University also contributed to the findings. This collective research underscores the need for a global approach to safeguard pregnant women during future pandemics and ensure their early inclusion in vaccination programs, which could ultimately save lives and reduce the impact of viral outbreaks.
In conclusion, the study calls for a paradigm shift in pandemic preparedness that prioritizes the health and safety of pregnant women, addressing their vulnerability through timely inclusion in vaccination efforts and ongoing research into safe and effective vaccines for this high-risk group.
