From 1 Feb 2019, foreign-born children aged 12 years and below will need to verify their vaccination (or evidence of immunity) for diphtheria and measles with the Health Promotion Board (HPB), before they can apply for a Dependant's Pass (DP) or Long Term Visit Pass (LTVP) with Ministry of Manpower.
Foreign children who are born in Singapore or are holding a DP/LTVP issued on or before 1 Feb 2019 will be exempted from this requirement.
