Information about COVID-19

We stay alert

COVID-19 is still among us, so we remain careful. Many patients at the Netherlands Cancer Institute are vulnerable despite their vaccinations. We work hard to protect these patients.

That's why we still wear face masks if we cannot keep a social distance. We will not shake hands with our patients. This is not to be unkind, but to prevent infections and bacteria from spreading.

A quick overview of our policy:


We wear a medical face mask if social distancing is not an option. You can get your mask at the main entrance. You do not have to take your mask off if that makes you feel more comfortable.

Do you have symptoms that might be related to COVID-19, such as a cold, runny nose, sneezing, sore throat, coughing, breathing problems, a fever, or temperature? Please do not come to the NKI. 

We will not shake hands with our patients. This is not to be unkind, but to prevent infections and bacteria from spreading.

Patients can receive more than 2 visitors a day. We only allow 2 people in a patient room at a time. Visitors will need to wear a surgical face mask if they cannot keep a social distance.

Visiting hours are between 15.50 and 19.30.

Keep a social distance when possible.

Patients coming in for admission or surgery can bring more than 1 support person. Not all departments allow support people, however.

Help stop the spread of COVID-19!

Our COVID-19 policy

Precautions will remain in effect

Patients with cancer are vulnerable. We have learned more and more about COVID-19, the coronavirus, over the past year and now know that patients with cancer - especially those with cancer in the blood (leukemia or lymphoma) and patients with metastases from lung cancer or other cancers who are receiving chemotherapy are at risk for more serious COVID-19 symptoms than people who do not have cancer. It is very important that all people with cancer receive vaccinations against COVID. The regular measures, hand hygiene, social distancing, wearing a face mask and barring entry for people with symptoms will remain in effect to prevent further spread of COVID-19.

Long distance consultations if possible

Our physicians and nurses will continue to schedule video consultations. We will contact you if your appointment at the hospital will be held through a video call. If you do not hear from us, you can assume that your appointment will not be changed. Please remember to notify us at +31 (0)20 – 512 9111 if you are experiencing respiratory symptoms (coughing or shortness of breath). We will assess your symptoms to see if we can safely proceed with your appointment.

Testing for COVID-19 before surgery

If you are admitted to the Netherlands Cancer Institute for surgery or procedure requiring general anesthesia, we will test you for COVID-19. This only applies to patients who are not vaccinated for COVID-19 and who are older than 65. You may have caught COVID-19 without showing symptoms (yet). 

We have started screening on November 22. We test patients two weekdays before their appointment at the OR with a PCR test. We will contact you in time to invite you to visit our yellow clinic (poli geel) here we will ask about any potential symptoms and administer a PCR test. 


Cold symptoms, shortness of breath, or fever?

Visitors and support persons

We request that visitors and support persons experiencing respiratory symptoms or fevers do not come to our hospital. We understand that this might be frustrating, but this measure is essential to guarantee a low risk of contracting COVID-19 at the hospital. 

Read more about our visitation policy


Are you coming in for hospital admission or an appointment? Please let us know, preferably a day in advance, whether you:

  • are experiencing health symptoms related to COVID-19;
  • tested positive for COVID-19;
  • are a close contact in contact tracing;
  • have returned from a color-coded red area and need to self-isolate.
  • have visited a medium or high-risk country within the last 10 days.

If any of the above apply, please contact +31(0)20 – 512 9111. We will assess your symptoms and determine whether you can come in for your appointment.

More information for patients

Patients with a slightly elevated temperature and mild symptoms who need treatment at the hospital will have to take extra precautions. We have set up a special hospital wing for patients with suspected COVID-19. They will be taken to this wing using a special route (yellow). All patients will receive information about our screening procedure one day before their visit.

In the hospital wing, we will ask you about your symptoms. We will discuss the best way to proceed together with your practicing physician. He or she will determine whether your consultation, treatment, or diagnostic procedure will continue. If not, we ask you to leave the hospital and come back at a later time. We will schedule a new appointment with you.

If we decide that we can proceed with your appointment, you will be escorted to the department or clinic where you had your appointment. We do not test for COVID-19 unless your practicing physician feels that it is necessary.

If you are experiencing symptoms without a fever, we will contact your practicing physician. The goal of these measures is to prevent patients with COVID-19 from walking around in our hospital and limit the number of tests to only those that are absolutely necessary.

Visitors and support policy adjusted

We allow more than 2 visitors a day. Only 2 people are allowed in a patent room at a time. All visitors have to wear a face mask if social distancing is not an option.

Please do not visit the NKI if you are experiencing symptoms that could be related to COVID-19/

Face mask / face shield policy

Face masks are no longer mandatory throughout our hospitals.

We kindly request that patients and visitors wear a face mask if social distancing is not an option. You can find a face mask at the front desk.

Social distancing - it works

Social distancing is mandatory at our institute to stop the spread of COVID-19.

RIVM Personal hygiene policy

To prevent the spread of COVID-19, we adhere to the RIVM personal hygiene policy:

  • Regularly wash your hands
  • Cover a sneeze or cough with your elbow
  • Use paper tissues
  • Do not shake hands
  • Stay home when experiencing cold symptoms

We recommend disinfecting your hands, or washing with water and soap when visiting the hospital.

Phone / video consultations when possible

Whenever possible, we will offer patients phone consultations instead of in-person consultations. We can opt for long-distance consultations if the patient does not need to be physically present and has the necessary technology available. These consultations can be used to discuss side effects of the treatment, or discuss the results of diagnostic testing or the next step in treatment, or to answer patient questions.

All patients for whom phone consultations are an option will be contacted on the day before their consultation to change their appointment to one over the phone. To avoid putting too much pressure on our phone operators, we ask that patients do not contact us to ask about these phone consultations themselves. If a phone consultation is an option for you, we will contact you. You can complete the consultation when you receive the call, or on the original date of your appointment. The exact time will depend on the assessment of the physician, clinical nurse specialist, and the patient.

If you did not receive a phone call, you can assume that you will need to be physically present during your consultation and that it cannot be handled over the phone. Please visit the hospital at the time of your appointment.

Contact before your appointment or admission

Are you coming to the hospital for admission o do you have an appointment at our Radiotherapy or Radiology Department, Outpatient Clinic, or OBC? Or is this your first time at the clinic? Please notify us immediately if you:

  • Are experiencing symptoms related to COVID-19;

Tighter measures after return from a color-coded orange or red region or contact screening


  • Return from a color-coded red or orange region

Have you been to a color-coded orange or red region in the past 10 days? Please contact your practicing physician at 020 5129111 before coming in for your appointment. If possible, we will reschedule your appointment to a date after your self-isolation period of 10 days. We follow the guidelines as outlined by the RIVM and urge you to self-isolate for a period of 10 days after returning from a color-coded red or orange country. If your treatment cannot be postponed, we will take adequate protective measures to protect you, our staff, visitors, and patients from a potential infection.

Were you marked as a close contact after contact screening, or are you self-isolating? Please contact your practicing physician before your visit to the NKI at 020 5129111.

  • Visitors and support persons

Visitors and support persons who have recently returned from a color-coded orange or red region are asked not to come to our hospital until after the self-isolation period of 10 days. These measures also apply to visitors and support persons who are self-isolating after having been marked as a close contact with someone who tested positive for COVID-19.

The use of face masks for patients who are deaf or rely on lip-reading

If you are deaf or hard of hearing, your health care provider can wear a face shield to allow you to lip-read as normal.

If you cannot wear a face mask due to your health, you can take it off once you are in the consultation room or office. As long as you keep a social distance of 1.5 meters at all times. You are welcome to use a face shield if you have one.

If you are bringing a support person, please make sure that he or she wears a face mask for the duration of the visit. He or she is welcome to wear a face shield as well.

Frequently asked questions about COVID vaccines

I am receiving immunotherapy and/or chemotherapy. Is a vaccination safe for me?

The VOICE study (a trial in which the Netherlands Cancer Institute participated)has shown that most patients with tumors in organs or tissue for which they are treated with immunotherapy and/or chemotherapy respond well to the COVID vaccine. Patients with cancer can receive their vaccine during the treatment, and this is safe for them.

The Dutch Health Council recommends a third vaccine for a certain patient group with serious immune disorders to increase protection against COVID. Thi booster shot will only be available to patients who are known or suspected to be insufficiently protected by their previous two vaccines by medical specialists. All patients who quality have received a letter about their vaccine.

We recommend all cancer patients to get their vaccinations when receiving an invitation from the government and not postponing the moment for the sake of their treatment. 

I am scheduled for surgery or radiation treatment. Is a vaccination safe for me?

There are no reasons to believe that patients with cancer are at risk of additional vaccine side effects. We recommend all cancer patients who are scheduled for surgery or radiation treatment to get their vaccinations.

Why do we ask to register your vaccination status in your medical file?

As of Thursday, June 3, we will register your vaccination status in your medical file. if you are vaccinated, we will register the date and type of vaccine. One of our members of staff will ask you about your vaccination status within the coming weeks if you have an appointment at the NKI. You are not obligated to give us this information if you would prefer not to.

we register this information because we want to ensure that you receive the best care and treatment possible. For that, we will need to have an accurate overview of our patients' situations, which requires information about various things like medications you take, and your vaccination status. We currently do not know whether the vaccines are as effective in preventing COVID-19 for people with cancer who are receiving immunotherapy or chemotherapy. That's why we also want to know the time of your vaccination.

Just like all other information in your medical file, we will handle your data with care and in accordance with the privacy regulations.

When can I get a booster vaccine?

People are eligible for a COVID-19 booster vaccine 3 months after their last vaccination (first, second and third vaccine). People who have had OVID-19 after their last vaccine can get the booster shot 3 months after recovery.
