Here's some comforting news for people who struggle with inflammatory bowel disease and worry that the immune-suppressing drugs they must take might blunt their response to COVID-19 vaccines: New research finds vaccination triggers a strong immune reaction in these patients.

"At eight weeks, following completion of a two-dose mRNA vaccine series, 99% of patients had detectable antibodies ...

Transplant patients and certain other folks may need four shots of COVID-19 vaccine for optimal protection, new research suggests.

People with weakened immune systems who've received both doses of two-dose COVID-19 vaccines aren't adequately protected against severe illness. They should be given a third shot plus a booster, according to the study.

"These findings indicate that while...

Severely immunocompromised people may require a fourth mRNA coronavirus shot, the U.S. Centers for Disease Control and Prevention says.

The agency didn't provide an official recommendation about a fourth shot in its updated guidelines, but did say that people should talk to their doctors to determine if one is necessary, CNN reported.

In August, the CDC authorized a third d...

Nine of 10 patients with so-called "bubble boy" immune disease who received gene therapy about a decade ago are still disease-free, researchers report.

The gene therapy was developed at the University of California, Los Angeles (UCLA), to treat the rare and deadly immune system disorder formally known as adenosine deaminase--deficient severe combined immunodeficiency (ADA-SCID).
