Questions about COVID-19 Vaccination?

Do I qualify for an additional dose of an mRNA COVID-19 vaccine?
Vaccination is recommended for all eligible persons based on FDA-approved indications or emergency use authorization (EUA). With the widespread availability of highly effective and safe vaccines, the committee reiterates the need for patients with cancer to be fully immunized, including receiving third doses and boosters. Vaccination is also recommended for caregivers, household/close contacts, and the general public. This statement reflects the evidence that patients with cancer or other immunocompromising conditions are most effectively protected from COVID-19 when they are immunized and their close contacts and general community are also vaccinated.
How effective is the vaccine and is it safe?
All three COVID-19 vaccines - Pfizer, Moderna and Johnson & Johnson - are safe and effective. All have been shown to reduce the risk of becoming infected with COVID-19 and reduce the risk of hospitalization. Most importantly, all have been shown to eliminate the risk of developing severe disease and death due to COVID-19. Getting vaccinated as soon as possible with the vaccine that is available will help protect you and your family against this virus.
Is there anyone who should not get the COVID-19 vaccine?

There are very few medical contraindications to vaccination. If you previously have had an anaphylactic reaction to another vaccine or medication, you still may receive the COVID-19 vaccine, but we will ask you to notify the staff and be monitored in the vaccination clinic for 30 minutes after you receive your injection. However, the FDA is recommending that individuals who have severe allergic reactions to any ingredients of a vaccine should not receive that vaccine. There are safety protocols in place at our clinics to quickly address severe allergic reactions following vaccine administration. Also, if you experience an allergic reaction to a vaccine, you may be referred to an Allergist for evaluation. For Pfizer or Moderna vaccines: if you experience an anaphylactic reaction to a first vaccine dose, you should not receive the second dose and instead consider getting the Janssen (J&J) vaccine. In addition, if you have had a stem cell transplant or CAR T-Cell therapy, we ask you to contact your oncology provider via MyChart message in advance of your COVID-19 vaccination to discuss the timing of your vaccination.

Children <12 should receive the pediatric formulation of the vaccine.


Should I get the vaccine if I had COVID-19?

The extent to which antibodies that develop in response to SARS-CoV-2 infection are protective is still under study. If these antibodies are protective, it's not known what antibody levels are needed to protect against reinfection. Therefore, even those who previously had COVID-19 can and should receive the COVID-19 vaccine if it has been at least four weeks since their first positive COVID-19 test.

One you receive the vaccine, you should continue to wear a mask until we achieve a level of herd immunity – or approximately 75% of the population vaccinated. While the vaccine is extremely effective, a small percentage (5% or less) of those who receive it may not be fully protected, so we need to continue to wear masks and other PPE, as well as to practice social distance and use other precautions.

How can I learn more?

If you have specific questions about how the vaccine might affect your health, it’s best to speak with your health care provider. The Centers for Disease Control and Prevention (CDC) also offers comprehensive information, including guidelines for vaccination. Visit the CDC website or call 1-800-232-4636 (1-800-CDC-INFO).
