Hindi na kailangang magsimula ulit ng first dose

Ang pasyenteng nakatanggap na ng isang dose ng HPV vaccine ay hindi na kailangang mag-restart ng series—ipagpatuloy lang ang vaccination schedule mula sa kung saan siya tumigil, kahit hindi alam kung HPV4 o HPV9 ang naibigay at kahit matagal na ang nakalipas. 1

Paano Ipagpatuloy ang Vaccination Series

Kung Nagsimula Bago Mag-15 Taong Gulang

  • Kung ang first dose ay ibinigay noong edad 14 years o mas bata, kailangan lang ng 1 additional dose para makumpleto ang series 1
  • Ang second dose ay dapat ibigay at least 6 months pagkatapos ng first dose 1
  • Ito ay 2-dose schedule na ang kailangan para sa edad na ito 1, 2

Kung Nagsimula Noong 15 Taong Gulang o Mas Matanda

  • Kailangan ng 3-dose schedule kung nagsimula ang vaccination sa edad 15 years o older 1, 2
  • Ang remaining doses ay dapat ibigay sa schedule na: second dose 1-2 months after first dose, at third dose 6 months after first dose 1
  • Minimum intervals: 4 weeks between first and second dose, at 12 weeks between second and third dose 1

Mahalagang Alituntunin sa Interrupted Schedule

  • Huwag i-restart ang series—ang CDC ay malinaw na nagsasabing kung na-interrupt ang schedule, ipagpatuloy lang mula sa natitirang doses 3, 1
  • Walang "too late" para ipagpatuloy—kahit ilang taon na ang nakalipas, valid pa rin ang nauna nang dose 3, 1
  • Hindi kailangan malaman kung HPV4 o HPV9 ang nauna—both vaccines are compatible at pwedeng ipagpatuloy ang series gamit ang available na vaccine (which is now HPV9) 4

Praktikal na Gabay

Kung Kasalukuyang Edad ay 26 Taong Gulang o Mas Bata

  • Ipagpatuloy ang vaccination series kaagad 1
  • Gamitin ang HPV9 (nonavalent) vaccine para sa remaining doses 1
  • Walang kailangang testing o screening bago magpatuloy ng vaccination 1

Kung Kasalukuyang Edad ay 27-45 Taong Gulang

  • Pwede pa ring ipagpatuloy through shared clinical decision-making 5
  • Mas mababa ang benefit kung marami nang sexual partners, pero may protection pa rin laban sa HPV types na hindi pa nakuha 5

Common Pitfalls na Iwasan

  • Huwag mag-restart ng series—ito ay pinakakaraniwang pagkakamali na nagreresulta sa unnecessary additional doses 1
  • Huwag maghintay ng "perfect timing"—approximately 24% ng adolescents ay sexually active na by 9th grade, kaya importante ang mabilis na pagkumpleto 1
  • Huwag mag-alala sa vaccine type mismatch—studies show na mixed schedules (HPV4 then HPV9, or vice versa) are immunogenic and safe 4

Karagdagang Konsiderasyon

  • Ang longer intervals between doses ay nagbibigay ng mas malakas na immune response—so ang mahabang gap ay hindi disadvantage 1
  • Pwedeng ibigay ang HPV vaccine kasama ng ibang age-appropriate vaccines sa same visit, using separate syringes 1
  • Cervical cancer screening recommendations ay hindi nagbago para sa vaccinated individuals—kailangan pa rin ng regular screening 1
