The Importance of Influenza Vaccination for Pregnant Women

Why Pregnant Women Should Prioritize Influenza Prevention
The moment a woman becomes pregnant, she is inundated with advice from all corners: avoid unpasteurized cheese (Listeria!), steer clear of changing cat litter (Toxoplasmosis!), and definitely rethink that trip to South America (Zika!). While these are valid concerns, influenza often gets sidelined, dismissed as ‘just the flu.’ However, the influenza virus poses a significant threat every year, especially to pregnant women.
In the 2009/2010 flu pandemic, the United States witnessed a substantial impact on pregnant women, with many requiring hospitalization. Tragically, 109 pregnant women lost their lives to confirmed or suspected flu infections. In comparison, while the Zika virus has garnered extensive media attention, it rarely results in hospitalization and has not led to maternal deaths.
Key Facts About the Flu and Pregnancy
- Is it too late to get a flu shot? It’s never too late! Flu season can begin as early as October and last until May, with February often seeing the highest number of cases. While vaccine effectiveness varies, it can reduce the risk of illness by 50% to 60% when the circulating viruses match the vaccine strains. Even in mismatched years, the vaccine offers some protection. If you haven’t had your flu shot, contact your healthcare provider promptly.
Additional Flu Prevention Tips
Aside from vaccination, maintaining healthy habits can further reduce flu risk. Avoid close contact with sick individuals, disinfect common surfaces, and practice good hygiene by washing hands frequently. If you experience flu symptoms, consult your healthcare provider quickly for possible antiviral medication, ideally within 48 hours, to mitigate symptoms and complications.
