Is the flu vaccine safe while undergoing cancer treatment?

One common myth of the anti-vaccine movement is that nurses are secretly giving people vaccines without consent. While it is not necessary for providers to receive signed informed consent before vaccination, they do, by law, need to provide the patient or their guardian with a Vaccine Information Statement. The claims that the child received a vaccine without consent make this entire story seem fictitious.

Some vaccines are perfectly safe for cancer patients, while others should be avoided. The two main types of vaccines at play are inactivated (killed) vaccines or vaccines containing live but weakened viruses. People with cancer or a weakened immune system should generally avoid vaccines with live viruses, as their immune systems may have trouble fighting even weakened viruses, leading to severe infections.

The American Cancer Society suggests that providers can recommend safe vaccines, and family members and caregivers should also consult their doctors about vaccinations.

For people with cancer, receiving the annual inactive flu shot is crucial due to the flu’s potential severity; however, they should steer clear of the nasal mist flu vaccine as it contains a live virus. Family members and caregivers should opt for the flu shot to safeguard themselves and those at high risk, unless the person with cancer has an extremely weakened immune system or resides in a germ-protected area, in which case they should not receive the nasal mist vaccine. Seek personalized advice from your doctor.
