CRC/C/VNM/CO/3-4 particularly through the revision of Decree No. 21 on the marketing of nutrition products and breast milk substitutes, and ensure that action is taken against those who violate the Decree, particularly those who advertise formula and provide free samples to mothers; (d) Take measures, including awareness-raising campaigns and the expansion of service delivery, to increase immunization rates among infant and preschool children, paying special attention to ethnicity and geographic location. Adolescent health 59. The Committee expresses its concern at the lack of information on adolescent health as well as at the reportedly high prevalence of abortions among teenagers. The Committee is further concerned at the limited access adolescents have to contraceptives and to reproductive health services, assistance and counselling. 60. The Committee urges the State party to collect data on adolescent health and to report thereon to the Committee in its next periodic report. Referring to its general comment No. 4 (2003) on adolescent health and development in the context of the Convention, the Committee recommends that the State party raise awareness and provide access to services for adolescents in relation to sexual and reproductive health, respond to the increasing number of teenage pregnancies and abortions, and facilitate access to contraceptives, as well as to quality reproductive health services, assistance and counselling. HIV/AIDS 61. The Committee notes with appreciation the progress made with regard to HIV/AIDS prevention, however, it remains concerned about the weak enforcement of HIV/AIDSrelated laws, and that children infected with HIV/AIDS are stigmatized, more vulnerable to institutionalization and tend to drop out of school to a greater extent. The Committee is moreover concerned at the unreliable information concerning the magnitude of HIV in the State party, resulting in fragmented policies and prevention mechanisms. 62. In the light of its general comment no. 3 (2003) on HIV/AIDS and the rights of the child, the Committee recommends that the State party take into account the International Guidelines on HIV/AIDS and Human Rights, and: (a) Take all measures to ensure effective enforcement of HIV/AIDS-related laws, including by conducting training for law enforcement officials, teachers, and professionals working with and for children, also with a view to ensuring that children affected by HIV/AIDS do not drop out of school and can enjoy inclusive education; (b) Launch awareness-raising programmes, including campaigns to combat the stigmatization of children with HIV/AIDS, and foster an environment that enables families with children affected by HIV/AIDS to keep them in their family environment rather than send them to institutions, inter alia, by establishing community-based child care and assistance services; (c) Integrate respect for the rights of the child into the development and implementation of its HIV/AIDS policies and strategies, with a particular emphasis on the Convention’s four general principles, namely, non-discrimination (art. 2), best interests of the child (art. 3), right to life (art. 6) and respect for the views of the child (art. 12), and effectively implement the National Action Plan for Children Affected by HIV/AIDS to 2010 with a Vision to 2020; (d) Improve the quality and extent of health-related disaggregated data, as regards both compilation and use, with a view to generating reliable data. 15
