Vaksinasi membantu memberikan perlindungan

Vaksinasi direkomendasikan tanpa melihat aktivitas seksual
seseorang atau paparan sebelumnya terhadap HPV.
Vaksinasi direkomendasikan bahkan bila pasien tersebut
positif pada tes HPV DNA

Primary prevention:
• Vaksin HPV
Vaksin Kanker Serviks
• Proteksi tehadap HPV
risiko tinggi yang paling
banyak menyebabkan
kanker (70%) yaitu
HPV 16 dan 18
Vaksin
Quadrivalen
Keuntungan Vaksin HPV
•
Vaksinasi merangsang pembentukan
antibodi serum
•Data menunjukkan bahwa antibodi
serum yang diinduksi vaksin,
bertransudasi ke lokasi infeksi
1-4
•Makin tinggi kadar antibodi serum,
artinya kadar antibodi di lokasi infeksi
juga semakin tinggi
5,6
•Antibodi menetralisir virus dan
mencegah virus masuk kedalam sel

Tes HPV
• Tes HPV yang ada hanya dapat mendeteksi apakah
seorang wanita telah terinfeksi HPV risiko tinggi
(16, 18, 31, 35, 45, 52, 58, dll)
• Tidak dapat menentukan jenis HPV yang
menginfeksi
Bukan merupakan keharusan sebelum
pemberian vaksin !!

Pedoman PAPDI – remaja putri & wanita berusia 12-55 tahun

Bila Hasil Tes Skrining Abnormal
• Bila hasil tes skrining abnormal, misal
terdapat lesi pra kanker
obati dulu lesi pra kanker tersebut
• Vaksin bukan merupakan pengobatan
untuk lesi pra kanker!!
• Efek samping minimal
• Antara lain :
– Kemerahan pada tempat suntikan
– Pusing
– Demam
Vaksin Jangan Diberikan Pada :
– Sakit Berat
– Hamil
– Dalam waktu dekat
berencana hamil
• Skrining rutin tetap
harus dilakukan
• Bukan berarti sudah
divaksinasi berarti
bebas skrining rutin
• Mengurangi risiko
70-80% terjadinya kanker
serviks
