I’m an Infectious Disease Doctor. Here’s the Problem with “Doing Your Own Research” on Vaccines

Key Points:

• Vaccine hesitancy is rising in the U.S., with increasing numbers of parents delaying or refusing childhood vaccines, leading to lower vaccination rates and falling below herd immunity thresholds for diseases like measles.
• Political interference and changing public health messaging under current leadership have undermined trust in vaccines, with censorship of supportive studies and promotion of vaccine skepticism contributing to public confusion.
• Social media and influencers often spread unverified or sensational anti-vaccine information, complicating parents' ability to find reliable, evidence-based advice on vaccination.
• Medical experts emphasize the importance of following guidance from reputable physician organizations and healthcare providers who understand individual medical histories rather than relying on social media or non-expert sources.
• Vaccines have saved millions of lives worldwide and remain essential for public health; declining vaccination rates threaten to reverse decades of progress and increase the risk of preventable disease outbreaks.
