Have FDA and CDC changed any HPV vaccine recommendations based on vaccine safety monitoring?

Yes. When fainting (or syncope) was found to happen after vaccination, FDA changed Gardasil’s guidance for doctors to include information about preventing falls and injuries from fainting after HPV vaccination. CDC and the Advisory Committee on Immunization Practices included this guidance in the recommendations for HPV vaccination. CDC continues to remind doctors and nurses to observe this guidance and to share this information with all their patients.
