Here are a few ways to rewrite the title in a formal, professional tone:
Option 1 (Direct and objective):
“Rising Refusal of Newborn Vaccinations Amid Misinformation Risks Public Health”
Option 2 (Focusing on the medical advisory):
“Medical Professionals Issue Warning as Declining Newborn Vaccination Rates Pose Severe Health Risks”
Option 3 (Concise and urgent):
“The Impact of Vaccine Misinformation on Infant Immunization Compliance”
Recommendation: Option 1 is the most balanced and suitable for a formal report or journalistic piece.
