Around 3% of people in the United States have compromised immune systems. HIV/AIDS patients, transplant recipients, cancer patients, and individuals with autoimmune diseases including rheumatoid arthritis, inflammatory bowel disease, and lupus are among them.

COVID-19 vaccines have not been tested in significant numbers of individuals with weak immune systems. However, limited evidence and experience with influenza and pneumonia vaccinations indicate that they will not perform as effectively in some people as they do in others.

This implies that those with poor immune systems should continue to take measures like wearing masks and avoiding big gatherings.

According to Dr Ajit Limaye from the University of Washington Medicine:

Although most cancer patients should be vaccinated as soon as possible, those who get stem cell transplants or CAR T-cell therapy should wait at least three months following treatment before getting vaccinated, according to the National Comprehensive Cancer Network’s recommendations. This time delay will ensure that the vaccinations are as effective as possible.

Researchers are still investigating if adding an additional dosage to transplant recipients’ vaccinations would improve their effectiveness.

The immuno-compromised, including organ recipients, should get a third COVID-19 dosage, according to French standards.

Transplant patients and those with weakened immune systems in Israel are now receiving an additional dosage of the Pfizer vaccine.

Even though the federal government has not approved additional vaccines, some transplant patients in the United States seek out a third dosage on their own in the hopes of better protection.
