Should people with cancer get vaccinated?

This is an automatically translated article.


People with cancer often have severely weakened immune systems, so the risk of infection is very high. Therefore, vaccination against certain strains of viruses is extremely important for cancer patients. However, which vaccines are appropriate and safe for them?

1. Should people with cancer get the vaccine?


Generally, health care professionals recommend that vaccines are not given during chemotherapy or radiation therapy for cancer, except for the flu shot. This is mainly because vaccines need an immune system response to work effectively, while the immune systems of people with cancer are often severely weakened by the treatment of the disease.
In the human body, the immune system consists of a group of cells, tissues and organs that work together to fight infections from harmful bacteria and viruses. On the other hand, the cancer condition and the measures used in cancer treatment can weaken the patient's immune system, preventing them from working as well as they should.
For people with weakened immune systems, careful consideration is required before choosing a vaccine: is the vaccine safe or not? Ideally, cancer patients should consult with a specialist about vaccination, risk factors for using vaccines, as well as the best time to get vaccinated.
In fact, some vaccines can be used to help a cancer patient's immune system respond to and fight off infections or diseases in general.

At this point, your doctor will be your trusted advisor to determine which vaccines are safe for you.

3. Influenza vaccination for cancer patients


It is recommended that most people get a flu shot each year to prevent infection with the flu virus. For cancer patients with severely weakened immune systems, flu prevention is essential, as influenza viruses can attack, wreak havoc on the immune system, and be life-threatening. sick.
Cancer patients should get an inactivated influenza vaccine (vaccine containing a dead/inactive influenza virus) every year. Some studies have shown that the flu virus can change continuously from year to year, so vaccines will also vary slightly to achieve the most protection. Also, the best time to get the flu vaccine will depend on the type of cancer and the individual patient's treatment.

For example, you should not get the nasal spray flu vaccine if a family member has recently had a stem cell or bone marrow transplant.
