Ohio Champions for Vaccines (OC4V)


Chair: Denise Warrick, MD, FAAP: Pediatrician, mom and advocate. Dr. Warrick is the mother of two and a pediatrician working in primary care in the Cincinnati-area. She is passionate about educating parents on the facts about vaccines.



Who we are: Ohio Champions for Vaccines (OC4V) is a group of Ohioans advocating for vaccines and spreading accurate information about the disease burden, safety and effectiveness of vaccines. All of us are fierce advocates for combatting misinformation on vaccines!

Why we care: Ohio’s immunization rates for children and adolescents are NOT where they need to be for all of our children to be protected from potentially dangerous vaccine-preventable diseases. The misinformation has scared parents, guardians and caregivers, and it is time to set the record straight.

What we do: We share factual, data-driven information and stories about vaccines. To get involved, agree to our pledge and you will be directed to a page with resources and information!
