COVID-19 Vaccination for NCCS Patients

Vaccination guidelines for people with cancer

According to the latest Ministry of Health guidelines (as of 28 July 2021), COVID-19 vaccination is recommended for cancer patients, including those on active cancer treatment.

All the categories below apply specifically to mRNA-based COVID-19 vaccines (i.e. Pfizer-BioNTech and Moderna COVID-19 vaccines), based on data currently available. These recommendations may change as more data becomes available locally and globally.

Allow Vaccination

​Active cancer not on treatment with chemotherapy, radiotherapy or immunotherapy CAN be vaccinated at any National Vaccination Centre.

Active cancer not on treatment is defined as:

a) Not on any treatment in the past 3 months AND

b) No planned treatment in the next 2 months.

​Persons on cancer hormonal therapy CAN be vaccinated at any National Vaccination Centre.
​Persons with a history of cancer, who are in remission, CAN be vaccinated at any National Vaccination Centre.

​Persons on active cancer treatment:

  • Chemotherapy
  • Radiation therapy or
  • Immunotherapy

CAN be considered for vaccination, after assessment by their primary oncologist on the eligibility. The primary oncologist will write a memo which the patient can take along with them to any National Vaccination Centre to get vaccinated.


If you are a NCCS patient, there are two ways to get the COVID-19 vaccination:

i) If you are currently NOT on active cancer treatment with chemotherapy, radiation therapy or immunotherapy, you should register for vaccination at National Vaccination Centres as part of the national COVID-19 vaccination programme.

Patients who are only on endocrine therapy, can also register for vaccination at any National Vaccination Centre.

ii) If you ARE CURRENTLY on active cancer chemotherapy, radiation therapy or immunotherapy (OR have received these treatments in the past 3 months or plan to receive these treatments in the next 2 months), and wish to be vaccinated, please seek your doctor’s advice at your next NCCS outpatient clinic consultation. Your doctor will discuss with you the risk and benefits of COVID-19 vaccination while you are on active cancer treatment and assess your eligibility to have the vaccination based on your clinical condition. If assessed to be eligible and you wish to proceed with vaccination, your doctor will write you a memo which you can take along to any National Vaccination Centre to get vaccinated.

Frequently Asked Questions

  1. Why is the COVID-19 vaccination now being recommended for cancer patients, including those currently on active cancer treatment?

    In Singapore, the Ministry of Health, Chapters of Medical Oncologists & Radiation Oncologists and College of Physicians of the Academy of Medicine, recommend that cancer patients, including those who are currently on active cancer treatment, should get COVID-19 vaccination. This is in line with international guidelines from organisations such as the American Society of Clinical Oncology and the European Society for Medical Oncology.

    This is because cancer patients are at increased risk of severe complications from COVID-19 infection. Vaccination protects cancer patients against COVID-19 infection and can reduce the risk of severe complications, should infection occur.

    In addition to vaccination, which is an important measure, patients should strictly adhere to safe management measures, such as wearing a face mask, frequent handwashing with soap, safe distancing, only going out for essentials, using TraceTogether and seeking prompt medical attention if feeling unwell.

  2. How do we know that COVID-19 vaccines are safe for cancer patients?

    There is currently no evidence of any safety signals or increased rates of adverse events from mRNA-based COVID-19 vaccines for cancer patients.


  3. What are the risks and benefits of getting COVID-19 vaccination?

    Cancer patients are at increased risk of severe complications from COVID-19 infections. Vaccination protects patients against COVID-19 infection and can reduce the risk of severe complications, should infection occur.

    Please seek your doctor’s advice at your next NCCS outpatient clinic consultation. Your doctor will discuss with you the risk and benefits of COVID-19 vaccination while you are on active cancer treatment and assess your eligibility to have the vaccination based on your clinical condition.

  4. How should I get COVID-19 vaccination if I am currently on active cancer treatment?

    At your next NCCS outpatient clinic consultation, please consult your doctor about COVID-19 vaccination. Your doctor will discuss with you the risk and benefits of COVID-19 vaccination while on active cancer treatment and assess your eligibility to have the vaccination based on your clinical condition. If assessed to be eligible and you wish to proceed with vaccination, your doctor will write you a memo which you can take along to any National Vaccination Centre to get vaccinated.

  5. Can I choose which COVID-19 vaccine I take?

    National Vaccination Centres currently use either the Pfizer-BioNTech or Moderna COVID-19 vaccines, which are approved by MOH. Each vaccination site will only administer one type of COVID-19 vaccine.

  6. Can dose 1 and dose 2 of the vaccination be done at different places?

    At the point of enrolment, appointments will be made for dose 1 and dose 2 at the same location.

    As different vaccination centres may use different types of the COVID-19 vaccine, you should return to the same vaccination centre for both doses of the vaccine.


  7. Will I get a vaccination certificate?

    A printed card will be given to you after your first and second vaccinations. In addition, you can access your vaccination records via Singpass online on Health Hub.

    Healthcare professionals (e.g. doctors at the hospitals, polyclinics and GPs) taking care of you can access your vaccination records through the National Electronic Health Records (NEHR) system.
