ACS Required Staff to Be Vaccinated Against COVID-19 in 2021: What the Policy Said
In August 2021 the American Cancer Society said all full- and part-time staff must be fully vaccinated against COVID-19 by November 1, 2021. Here is what the policy said, and what it did not.
Original commentary from the Cancer Explained editorial team.

Historical context: this page explains an event dated 2021-08-24. It was published as an explainer on September 30, 2026 and is not breaking news.
Please note: this page is educational only — it is not medical advice, and it does not speculate about anyone’s health beyond reliable public reporting. For questions about your own health, talk with your healthcare team.
What the American Cancer Society announced
On August 24, 2021, the American Cancer Society (ACS) published a press release titled "American Cancer Society Announces COVID-19 Vaccine Policy for Staff." It said all full- and part-time staff "will need to be fully vaccinated by November 1, 2021."
The release said the policy was "only for employees." It did not extend to volunteers or program participants "at this time."
So this was a requirement for people who worked for ACS. It was not a rule for patients, and it was not a law.
An earlier statement, in July 2021
About a month before, on July 28, 2021, ACS said it supported mandatory COVID-19 vaccination for health care workers. That statement quoted its chief executive, Dr. Karen E. Knudsen: "We support mandatory COVID-19 vaccinations for all health care workers. This is urgent."
In the same statement, ACS said it was requiring vaccines for staff and volunteers who work with patients and caregivers at its Hope Lodge residential facilities and in its Road to Recovery transportation program.
Hope Lodge gives people free places to stay during treatment. Road to Recovery drives patients to appointments. In both programs, staff and volunteers spend time close to people who may have weak immune systems.
The reason ACS gave
The August release gave this reason: "COVID-19 continues to pose a serious health threat to cancer patients, survivors, and the public at large." It described the vaccines as safe and effective at lowering the risk of severe illness.
That is ACS explaining its own decision. This page does not add a medical claim of its own.
What the release did not say
- The release did not mention exemptions or accommodations. We do not know from these pages how requests were handled.
- It did not say what happens to an employee who does not comply.
- The release is from 2021. We did not find a source that says whether the policy is still in force today, so we do not say it is.
Why this matters to patients
People with cancer often have weaker immune defenses. That can be true during chemotherapy and some other treatments. Programs that serve them often ask staff and volunteers to follow health rules. Vaccination is one such rule.
You do not need to know an organization's staff policy to plan your own care. What matters more is talking with your own care team about your own vaccines and their timing. Our page on COVID-19 vaccine timing during chemotherapy explains what to ask.
If you use lodging or transportation help, our guides on help with lodging and transportation to treatment list where to find it. Ask each program directly what its current health rules are.
Questions to ask your care team
- Which vaccines are right for me now, and when should I get them?
- Does the timing of my treatment change when I should be vaccinated?
- If I use a lodging or ride program, are there health rules I should know about?
- Who in my household should be up to date on vaccines?

Put the story in context
Prevention, possible warning signs, screening, and diagnosis
This story relates to COVID-19 vaccination and cancer organizations. The information below is general: it does not reveal anything else about a public person’s health, and not every point applies to every cancer. Personal advice depends on age, symptoms, family history, exposures, and medical history.
Prevention and risk reduction
Not every cancer can be prevented. Avoiding tobacco, protecting skin from ultraviolet radiation, limiting alcohol, staying active, and receiving recommended HPV or hepatitis B vaccination can lower the risk of certain cancers. A risk factor is not a prediction or a cause in one individual.
Symptoms and possible early signs
Possible signs vary and are often caused by conditions other than cancer. Changes worth discussing include a new lump, unexplained bleeding or weight loss, a persistent cough, lasting bowel or bladder changes, a changing skin spot, or symptoms that persist or worsen. Some early cancers cause no symptoms.
Screening and early detection
Screening looks for certain cancers before symptoms begin. Recommended tests exist only for some cancers and depend on age and risk. Screening can have benefits and harms; it is not the same as evaluating a new symptom, and there is no single routine scan or blood test that reliably screens for every cancer.
How cancer is diagnosed
Diagnosis may involve a history and exam, imaging, laboratory tests, and often a biopsy. Pathology can identify the cancer type and may test biomarkers that guide treatment. Symptoms, screening results, tumor markers, or online stories alone cannot confirm cancer.
