Certain adults are at increased risk of complications or susceptible to vaccine preventable diseases if they have not previously received the vaccination and are in contact with individuals who have the infection. Vaccinations recommended under the NAIS aim to prevent such infections among susceptible individuals and reduce complications, morbidity, and mortality.2
The NAIS was developed based on international best practice and the recommendations of the Expert Committee on Immunisation (ECI). Considerations include:
Local disease burden;
Age, occupation, pre-existing medical conditions, vaccination history;
Vaccine safety, efficacy and cost effectiveness of the vaccines in preventing infections among susceptible individuals and reducing complications, morbidity and mortality.
The NAIS is summarised in Table 1 below.1 Government subsidies are available for NAIS vaccinations – see Financing section.

Other Vaccinations
For the use of other vaccinations not part of NAIS (e.g. yellow fever for travel to endemic areas, meningococcal for Haj), please refer to the Package Insert (PI), available on the Register of Therapeutic Products (under E-services, Infosearch) on the Health Sciences Authority (HSA) website. There is no need to report to the National Immunisation Registry (NIR) for these.
Administering Vaccinations
Healthcare providers should ensure the following during the administration of any vaccine:
The vaccine is being given to the correct patient.
The vaccine is given at the appropriate time, i.e. appropriate age and interval.
The correct vaccine and diluent are given to the patient.
The appropriate dose has been measured.
The vaccine is being administered via the correct route and technique e.g. subcutaneously vs intramuscularly.
The vaccine is administered at the correct site e.g. deltoid vs anterolateral thigh.
The vaccination details should be documented in NIR and the clinic's Electronic Medical Records (EMR) accurately with the type of vaccine, diluent, dose, batch, expiry, date and time administered, route, and consent.
After the administration of vaccines, patients should be observed for any immediate post-vaccination adverse effects. Patients should also be advised to monitor for possible side effects of the vaccine once they have been discharged.
