The National Adult Immunisation Schedule (NAIS) was established in November 2017 to provide guidance on vaccinations that persons age 18 years or older should adopt to protect themselves against vaccine-preventable diseases. In Sep 2025, two new vaccines against shingles and pneumococcal disease have been added to the NAIS, which are reflected in the updated schedule in Table 1.
Table 1: National Adult Immunisation Schedule
From 1st November 2020, The CDMP/CHAS Chronic guidelines on recommended groups for seasonal influenza vaccination will take reference from the latest NAIS/NCIS guidelines on nationally recommended groups for seasonal influenza vaccination. Please refer to Paragraph 8 of MOH Circular 53/2020 Clarification On Enhanced Coverage Under Chronic Disease Management Programme (CDMP/CHAS) for Influenza Vaccination and Updated Data Sharing Notice for the updated list of CDMP conditions recommended for influenza vaccination.
