Does injection of monoclonal antibodies against Covid-19 delay cancer treatment? – VnExpress

Cancer patients injected with monoclonal antibodies to prevent Covid-19 do not need to delay treatment because according to research, this antibody has few side effects and does not affect drugs.

Hello doctor, I am being treated for cancer. When I heard information about monoclonal antibodies against Covid-19, I researched and really wanted to be injected. However, I am worried if I inject this antibody, will I have to stop my cancer treatment? Ask your doctor for an answer. (Phuoc Sang, 38 years old, HCMC)


Research published by AstraZeneca shows that a monoclonal antibody against Covid-19 helps to bring the necessary amount of antibodies into the body with a preventive effect of up to 83%, even with the Omicron variant. This effect is demonstrated in people who are immunocompromised due to disease or are taking immunosuppressive drugs (such as organ transplant recipients, cancer, kidney failure, HIV…). This is a group of patients who are less likely to make antibodies after receiving the Covid-19 vaccine.

AstraZeneca’s monoclonal anti-Covid-19 antibody has almost no side effects and is not antagonistic to any drugs. Therefore, it is theoretically possible to inject a monoclonal antibody against Covid-19 during cancer treatment and without delaying treatment after injection. However, in practice, for cancer drugs that can be delayed, we recommend that patients consider a one-week delay for two reasons:

One is for the patient to be psychologically comfortable, reducing unnecessary anxiety. Because cancer patients are already under a lot of pressure due to malignancy, side effects of treatment… The purpose of injecting monoclonal antibodies to prevent Covid-19 is to protect patient safety. There should be no additional post-injection pressure that worries the patient.

The second is for patients to realize that the injection of monoclonal antibodies against Covid-19 has almost no side effects. If cancer treatment is started immediately after injection, patients may think that the treatment after injection of monoclonal antibodies against Covid-19 causes more fatigue, leading to suspicion and mistaken belief that because of injection of monoclonal antibodies. Covid-19 prevention led to this situation.

When deciding to inject monoclonal antibodies against Covid-19, patients and their families all hope to increase the protective effect. If it causes anxiety, psychological panic is not worth it. Therefore, the time to rest after injection helps patients and families feel secure.

If a cancer patient is in continuous treatment and/or requires daily medication…, the patient can still continue treatment after injection of monoclonal antibodies against Covid-19, without delay. they eat.
