Can I get vaccinated against COVID-19 while being actively treated for cancer?

  • A new study raises concerns about vaccine hesitancy among young survivors of cancer in the United States.
  • Cancer survivors often have weakened immune systems due to the cancer itself or certain treatments, so they may be at a higher risk of a severe form of COVID-19.
  • National organizations strongly recommend that cancer survivors receive their COVID-19 vaccine and seek the advice of their healthcare teams if unsure about vaccination.

Why are young cancer survivors concerned about COVID-19 vaccination?

Some adolescent and young adult cancer survivors are hesitant to get vaccinated against COVID-19, according to a new study published in JNCI Cancer Spectrum.

The study assessed 342 adults from the western U.S., who were diagnosed with cancer between the ages of 15 and 39 years.

While the majority of those surveyed intended to get the vaccine, more than a third (37.1%) expressed some COVID-19 vaccine hesitancy.

COVID-19 risk

As of June 2021, there were more than 33 million cases and nearly 600,000 deaths from COVID-19 in the U.S.

Vaccines offer one of the best tactics to control the spread of the novel coronavirus and end the pandemic. However, an estimated 20–30% of the U.S. population exhibit some vaccine hesitancy, meaning they are cautious about receiving or would refuse a COVID-19 vaccine.

Such hesitancy could be a particular problem for the cancer community. Certain types of cancer, particularly blood cancers like leukemia and lymphoma, and certain types of cancer treatment can have a major impact on the immune system.

“Generally speaking, people with cancer are often at risk for many types of infections. This is often because of the cancer itself and certain types of treatment,” said Austin Waters from the Huntsman Cancer Institute at the University of Utah, who led the study.

“Like other infections, people with cancer are at higher risk of contracting [SARS-CoV-2] than the general public. They are also at higher risk of severe complications to COVID-19 complications if they [contract] the virus,” Waters told medical News Today.

However, the picture is less clear for those who had cancer in the past — some of whom might be dealing with long-term effects from the disease or treatment, while others might not.

“There’s less information to go on at this time when it comes to people who’ve completed treatment,” Dr. Rick Alteri, medical editor of the American Cancer Society, told Medical News Today. “This is clearly an area where more research is needed.”

Sociodemographic factors and misinformation

The study’s authors aimed to identify sociodemographic factors that are associated with COVID-19 vaccine hesitancy among young cancer survivors.

Interestingly, young female cancer survivors were less keen on COVID-19 vaccination, with 42% of female survey respondents indicating vaccine hesitancy, compared with 30.1% of male respondents. The authors suggest that this gender discrepancy could be driven by misinformation asserting that COVID-19 vaccination causes infertility Trusted Source.

“Even before COVID-19, fertility has been and continues to be a concern for many adolescents and young adults during and after their cancer therapies,” Waters explained. “Fertility preservation for patients who have a uterus is often highly expensive, not covered by insurers, and can delay treatment. Thus, fertility is often at the front of [their] minds, potentially leaving them particularly vulnerable to misinformation about the COVID-19 vaccine and infertility.”

Cancer survivors with a high school education or less also showed greater vaccine hesitancy, compared with college graduates. Possibly, lower educational attainment is associated with lower health literacy, which may leave certain cancer survivors more susceptible to misunderstanding public health messaging surrounding vaccination.

Concerns for cancer survivors

While the survey did not ask respondents why or why not they intended to obtain a COVID-19 vaccine, some key factors are particularly relevant to cancer survivors.

“Cancer survivors are likely to have many of the same concerns as other people regarding the vaccines — that is, are they safe, and are they effective? But survivors might have some additional concerns as well,” said Dr. Alteri.

One frequent concern is whether their cancer or treatment might impact how well the vaccine works for them.

“Cancer treatments that have a major impact on the immune system, such as stem cell transplants and CAR T-cell therapy, are the most likely ones to dampen the immune response to the vaccines. So much so, in fact, that people getting these treatments are often advised to wait at least 3 months after treatment before getting vaccinated,” noted Dr. Alteri.

“Other treatments such as chemotherapy, targeted drug therapy, radiation therapy, and different kinds of immunotherapy might also affect the immune system to different degrees.”

Additional considerations include the timing of vaccination for those still undergoing treatment or those who require follow-up imaging tests.

“While these are certainly good questions for survivors to ask their [healthcare professionals], we stress that the vaccine is recommended for the vast majority of cancer survivors regardless of if they are actively receiving cancer treatment or not,” noted Waters.
