During the transition from childhood to adulthood, adolescents establish patterns of behavior and make lifestyle choices that affect both their current and future health. Serious health and safety issues such as violence, substance use, and risky sexual behaviors can adversely affect adolescent and young adults.1

Some adolescents also struggle to adopt behaviors that could decrease their risk of developing chronic diseases in adulthood, such as eating nutritiously, engaging in physical activity, and choosing not to use tobacco. Environmental factors such as family, peer group, school, and community characteristics also contribute to adolescents' health and risk behaviors.

Babies and little kids get shots called 4-in-1 (DTaP-IPV) to protect them from diphtheria, tetanus, pertussis (whooping cough) and polio. But as kids get older, the protection from the 4-in-1 shots starts to wear off. This can put your preteen or teen at risk for serious illness. A booster shot that helps protect your preteen or teen from the same diseases that 4-in-1 shots protect little kids from. Department of Health provides free booster vaccine to primary six students in Hong Kong.2

Starting from the 2019/20 school year, eligible female primary school students are provided with human papillomavirus (HPV) vaccine under the Hong Kong Childhood Immunisation Programme (HKCIP). The arrangement is implemented on the recommendations jointly made by the Scientific Committee on Vaccine Preventable Diseases (SCVPD) and the Scientific Committee on AIDS and Sexually Transmitted Infections (SCAS) under the CHP to incorporate HPV vaccine into the HKCIP.3

Additionally, adolescents are having continuous risk on several diseases. If your children will study or travel abroad, some countries require vaccination against infectious diseases such as Meningococcal infection, Japanese Encephalitis, or Yellow Fever.4
