COVID-19 vaccines: what you need to know

This page was updated on April 15.

The Fred Hutch/SCCA COVID-19 Vaccination Program is scheduling first dose appointments for eligible individuals. As more people are now eligible for the vaccine, we expect high demand and increased wait times for appointments.  See "How do I schedule my vaccine?" below for details on the scheduling process. Thank you for your patience.

Who is currently eligible to receive the vaccine?

All people 16 years or older are eligible for the vaccine. Please note that the Pfizer BioNTech vaccine is the only vaccine FDA approved for people 16 years and older. The Moderna vaccine is FDA approved for people 18 years and older. 

How do I schedule my vaccine?

The Fred Hutch/SCCA COVID-19 Vaccination Program is currently scheduling first dose appointments for eligible individuals as supply allows. We continue to give second doses to individuals who got their first dose at our site.

You can schedule your first dose of the vaccine as follows:

SCCA patients

  • All SCCA patients with valid email addresses on file should have received an email with information on how to schedule their vaccine at the Fred Hutch/SCCA COVID-19 Vaccination Program. 
  • If you did not receive an email and are being scheduled for in person or telehealth care at SCCA, you have two options: 

    • When you schedule your next appointment for care, tell your team coordinator/scheduler that you would like to schedule a vaccine appointment. They can offer you a vaccine based on available supply. If you would like to schedule your eligible caregiver at that time, you can.
    • Eligible SCCA patients without an upcoming appointment or valid email address on file can visit DOH's online Washington State vaccine locator to check for appointments throughout the state. Scheduling for the Fred Hutch/SCCA COVID-19 Vaccine Program can be accessed through the vaccine locator. 

General community

When will people with cancer be able to get the vaccine?

Most people with cancer should be able to get the vaccine now, as supply allows. See “Who is eligible to get the vaccine?” for details.

For information on vaccine safety and cancer, please see “Vaccine safety and guidelines for people with cancer” below.

Which vaccine does SCCA offer?

The Fred Hutch/SCCA COVID-19 Vaccination Program offers the Pfizer-BioNTech vaccine. We are not currently offering the Johnson & Johnson (Janssen) vaccine. To learn about the CDC's announcement on this vaccine click here.

Vaccine safety and guidelines for people with cancer

Should people with cancer get the COVID-19 vaccine?

Although COVID-19 vaccines have been shown to be safe and effective in the general population, data on their effectiveness in people who are immunocompromised is unknown. Currently the National Comprehensive Cancer Network (NCCN) and other major cancer organizations recommend that COVID-19 vaccines should be given to all people with cancer when they are eligible to receive the vaccine, based on the following guidelines. These guidelines may change over time as more data is gathered. Updates will be posted on this page and on the NCCN page.


Type of patient

Vaccine timing

Patients receiving care at the Blood and Marrow Transplant Clinic or Bezos Family Immunotherapy Clinic

  • Autologous and allogeneic transplant and immunotherapy patients must be at least 3 months post-transplant/treatment.
  • Patients on 1 mg/kg or more of steroids such as prednisone should talk to their providers to determine the best time for vaccination.

Patients with hematologic malignancies

  • Patients receiving intensive cytotoxic chemotherapy (e.g. cytarabine/anthracycline- based induction regimens for AML) should wait until absolute neutrophil count (ANC) recovery.
  • Patients with marrow failure from disease and/or therapy expected to have limited or no recovery, as well as those on long-term maintenance therapy (e.g., targeted agents for chronic lymphocytic leukemia or myeloproliferative neoplasms) should be vaccinated when vaccine is available.

Patients with solid tumors

Patients should be vaccinated when vaccine is available.

Patients currently enrolled in a clinical trial

Patients should contact their clinical or research team to confirm if they are eligible to receive the vaccine.

Patients with upcoming major surgery

Patients should separate their date of surgery from their date of vaccination by at least a few days.

Patients who have received another vaccine

Patients should wait for 14 days before they get the COVID-19 vaccine.

Should pregnant and breastfeeding mothers get the vaccine?

Pregnant and breastfeeding women should get the vaccine once it is available to them. We know that:

  • Pregnant or breastfeeding women were not included in the COVID-19 clinical trials.
  • The risk of maternal or fetal harm from an mRNA vaccine is unknown but thought to be low.
  • COVID-19 disease carries an increased risk in pregnancy. This is particularly true for patients with obesity or other medical conditions.

The UW Department of Obstetrics and Gynecology, Society of Maternal-Fetal Medicine and the American College of Obstetricians and Gynecologists support offering the COVID-19 vaccine to pregnant and breastfeeding patients.

Please speak to your doctor if you are concerned or have more questions.

How do we really know that COVID-19 vaccines are safe?

COVID-19 vaccines were tested in large clinical trials to make sure they meet safety standards. Many people were recruited to participate in these trials to see how the vaccines offer protection to people of different ages, races, and ethnicities, as well as those with different medical conditions. 

In both the Moderna and Pfizer-BioNTech vaccine trials, the rate of serious adverse events was low. Additional data on long-term safety will be available with more time and as more people get vaccinated.

What Is an Emergency Use Authorization?

Will the vaccine give me COVID-19?

No, it is not possible to get COVID-19 from vaccines. The new COVID-19 vaccines use inactivated SARS-CoV-2 virus, parts of the virus (like the spike protein) or a gene from the virus. None of these can cause COVID-19.

What are the side effects of the vaccine?

Vaccine side effects may be unpleasant but are not dangerous. In clinical trials, some people experienced fever, muscle pain, joint pain, fatigue and headaches. Most people will not experience side effects that prevent daily activity.

What to expect

How many shots of the vaccine will I need?

The COVID-19 vaccines that are currently available need two shots to be effective.

How long will the vaccine protect me? Will I have to get a COVID-19 shot every year?

We don’t know yet. Both natural immunity and vaccine-induced immunity are important aspects of COVID-19 that experts are trying to learn more about.

If I already had COVID-19 and recovered, should I still get vaccinated?

The CDC recommends that people who have had COVID-19 and recovered — and are no longer required to be in isolation — get the vaccine. Because it is uncommon to get COVID-19 again within 90 days of initial infection,  it may be reasonable to delay your vaccine until the end of the 90-day period. 

If I get a COVID-19 vaccine, do I still have to wear a mask and practice physical distancing?

Yes. To prevent unvaccinated people from getting sick, it's important to continue washing your hands, wearing a mask, staying 6 feet apart from those outside your household, and limiting gatherings until enough people have received the vaccine.

We know vaccination will prevent you from getting sick, but we don’t yet know if the vaccine will prevent you from spreading the virus to others.

After you've been vaccinated

What can I do after I am fully vaccinated? Do I still need to protect myself and others?

If it has been two weeks since you received your second dose of the PfizerBioNTech or Moderna vaccine or your
single dose of the Johnson & Johnson vaccine, you are considered “fully vaccinated”. We have separated the
guidelines for fully vaccinated people into two groups. Please make sure to follow the guidelines that apply to you.

Group 1

Includes fully vaccinated SCCA patients who:

  • Have not yet started treatment
  • Are in active treatment
  • Have recently completed treatment
  • Have weakened immune symptoms; for example, allogeneic and autologous transplant patients

Guidance for group 1

These patients should remain cautious. Although you may hear that others may get together after getting
vaccinated, people with cancer are more vulnerable. We don’t know how well the vaccines work in people with
cancer, particularly those who are on active treatment.
Until we know more about the effectiveness of vaccines in cancer patients, fully vaccinated people with cancer
should continue to:

  • Wear a well-fitted mask and practicing physical distancing when in public.
  • Wear masks, practice physical distancing, and follow other prevention measures when visiting with
  • unvaccinated people outside of your household.
  • Avoid in-person gatherings with those outside your household.
  • Avoid airline travel
  • Get tested if experiencing COVID-19 symptoms.

Group 2

Includes fully vaccinated SCCA patients who:

  • Are long term cancer survivors not on immunosuppression
  • Have a disease that required surgery only (no chemotherapy or radiation).
  • Have cancer treated with hormone therapy only


Fully vaccinated healthy caregivers and household contacts

Guidance for group 2

According to the CDC, these people:

  • Can visit indoors, in small groups, with other fully vaccinated people without wearing masks or physical distancing at either your house or theirs
  • Can visit indoors with unvaccinated people from a single household who are at low risk for COVID-19 without wearing masks or physical distancing at either your house or theirs. Low risk means that those people are being very cautious, masking and physical distancing.
  • No longer need to quarantine or get a COVID-19 test after a known exposure if they do not have symptoms (are asymptomatic).
  • Should continue to protect themselves in public, including wearing a well-fitted mask, physical distancing, and avoiding crowds and poorly ventilated spaces.
I am immunocompromised. Will an antibody (serological) test tell me if the vaccine was effective?

The Centers for Disease Control (CDC) and National Comprehensive Cancer Network (NCCN) do not recommend routine antibody testing after getting the COVID-19 vaccine. Currently, it is not known what antibody level is needed for protection in the general population and people who are immunocompromised. COVID-19 vaccine data in cancer patients continues to be limited, so it is important to continue wearing masks, keeping socially distant, and avoiding crowds and gatherings even after getting vaccinated.

I was exposed to someone with COVID-19 within two weeks of getting the vaccine. How do I tell the difference between having a standard reaction to the vaccine and having COVID-19?

Typically, most vaccine-related side effects go away within 1-3 days. If you have symptoms such as cough, loss of taste/smell, or shortness of breath after getting your vaccine, we strongly recommend getting tested for COVID-19.  

Fever is more common after the second dose, but it can also be a symptom of COVID-19. If you develop a fever, sore throat, cough, fatigue or any other COVID-19 symptoms after being exposed to someone with proven COVID-19, you should get tested whether you have gotten the vaccine or not.

You may wonder whether your COVID-19 test results will be accurate right after you’ve been vaccinated. COVID-19 nasal swab tests check for the virus—not your body’s immune response to the vaccine—so test results from a nasal swab won’t be affected by the vaccine.

We do not know how well the vaccine works in people who are immunocompromised and people who have cancer. Because of this, it is important to continue wearing masks, keeping physically distanced, and avoiding crowds and gatherings even after getting vaccinated.


How do vaccines work?

The COVID-19 vaccine teaches your immune system to recognize the coronavirus. When you get the vaccine, your immune system makes antibodies (“protein fighters”) against SARS-CoV-2, the virus that causes COVID-19. These antibodies stay in your blood and protect you in case you are infected with the virus. 

These vaccines have been shown to prevent the major complications of infection, COVID-19 disease and hospitalization. When enough people in the community can fight off the coronavirus— something called herd or population immunity—it has nowhere to go. This means the virus has a harder time spreading, and we get closer to ending the pandemic.

Why should I get vaccinated for COVID-19?

Studies show that people who were vaccinated against COVID-19 were less likely to get seriously ill from COVID-19 even if they were  infected with the virus. Although the level of protection for people with cancer isn’t clear yet, experts recommend that many people with cancer get vaccinated. Vaccination may also help reduce the spread of a virus and protect the people around you, including those who are at increased risk for severe illness from COVID-19.

Will the vaccine stop the pandemic?

Based on what we know about viruses, vaccines are likely to be a critical part of curbing the pandemic. Stopping a pandemic requires us to use all the tools we have available, including masks, physical distancing and vaccines to help limit the spread. The more people continue to follow good prevention practices, the faster we can get this pandemic under control — but we aren’t there yet.
