[Acceptability of vaccination against human papillomavirus (HPV) by pediatricians, mothers and young women in Ho Chi Minh City, Vietnam].

BACKGROUND: Cervical cancer (CC) is almost always induced by some oncogenic types of human papillomavirus (HPV). In Vietnam, it is the first leading cause of cancer in women, with highest prevalence in Ho Chi Minh City (HCMC). Since 2006, prevention of the CC has been improved by licensure of recombinant vaccines directed against HPV 16 and 18, effective when administered before the age of first sexual intercourse. A national program for routine immunization of pre-adolescent girls in addition to cytological screening of adult women would greatly reduce the impact of CC in Vietnam but vaccines remain expensive and it is unclear how this strategy would be accepted by the target population. The aim of this study was to assess the acceptability of HPV vaccination by pediatricians, mothers with a daughter aged 9-15 years and young women aged 16-26 years in HCMC.

METHODS: Between March and June 2010, a cross-sectional survey of knowledge and attitudes was administered to 115 pediatricians in the pediatric hospital, 210 mothers and 400 young women attending the gynecology department of the University Hospital.

RESULTS: Pediatricians generally had a good perception of the risk but they still lacked knowledge about HPV vaccination, given by 66% of them. Among mothers, 18% knew the relationship between HPV infection and CC, 43% had heard of HPV vaccination and 40% agreed to vaccinate their daughter. Among young women, 35% knew the risk, 49% knew the vaccine and 38% wanted to be vaccinated. Level of education, amount of income and celibacy were positively related to intention to be vaccinated. The lack of information on HPV vaccination and the high cost of vaccines were the main causes of refusal or indecision.

CONCLUSION: Routine HPV vaccination of girls in HCMC will be well accepted by the population if a large campaign of health education is implemented by the government and if the affordability of vaccines is facilitated.
