Single HPV Vaccine Dose Provides Protection Equivalent to Two Doses

A study published in the New England Journal of Medicine found that a single dose of the HPV vaccine is as effective as the standard two-dose schedule in preventing persistent infections.

The research, led by Dr. Aimee Kreimer and Dr. Carolina Porras, involved over 20,000 girls aged 12 to 16 in Costa Rica between November 2017 and February 2020.

With cervical cancer killing 2.5 lakh women annually and global vaccine coverage below 30%, this finding could significantly simplify vaccination efforts in regions with limited healthcare access.
