Allergy & Immunology 

John Sealy

FellowshipAllergy & Immunology

The University of Texas Medical Branch (UTMB) at Galveston offers a training program in Allergy and Clinical Immunology, which is fully accredited by the American Medical Association Liaison Committee on Graduate Medical Education. This is a conjoint program offered by the Allergy & Immunology Division of the Department of Internal Medicine and the Division of Infectious Diseases and Immunology of the Department of Pediatrics.

UTMB is the oldest medical school in Texas and the second oldest in the western states. The UTMB complex consists of integrated schools of medicine, graduate biomedical sciences, allied health sciences, and nursing. The core faculty for this program within the Departments of Internal Medicine and Pediatrics includes six full-time physicians board-certified in Allergy and Immunology. Our program is the home of the NHLBI Proteomics Center, the NIEHS Environmental Health Center, the Child Health Research Center and the Institute for Translational Science funded by the NIH Institutional Clinical Translational Science Award (ICTSA). These facilities serve as critical parts of the Allergy and Immunology Fellowship Program.

Started in 1970, UTMB is one of the oldest programs in Allergy and Immunology in the country. The objective of the training program is to provide advanced education in basic immunology, comprehensive training in allergy and clinical immunology, and laboratory training in basic and clinical research. UTMB has had a 100% pass rate in the American Board of Allergy and Immunology certifying exam for the last 10 years.

I invite you to visit the rest of our website and submit an ERAS application to our program. Thank you for your interest and consideration.

Clinical and Research years: During the 2 year program, fellows alternate between clinical and research years. The clinical year consists of 7 half days of clinic per week and 2 half days dedicated for research. Clinical fellows take primary call about 14 weeks out of the year.  During the research year, a fellow will be in clinic 3 half days per week and 6 half days devoted to research time. Research fellows take primary call about 3 to 4 weeks per year.

Conference Curriculum: Educational conferences are held weekly on Thursday afternoons and include board review lectures, journal clubs, case discussions, and workshops.

Education Materials: Two textbooks are provided by the program to each fellow in training. The first is Middleton's Allergy - Principles and Practice. The other is Cellular and Molecular Immunology by Abbas.

Meetings: Our fellowship program supports the attendance of fellows to our specialty's major medical conferences and they are encouraged to present the results of their research studies at these meetings. Fellows in training are provided financial support for this purpose.

ADD an Admissions Tab

Generally, physicians will be accepted for this program who have completed their training in Internal Medicine or Pediatrics and are board eligible, and after completion of this program can apply for certification by the American Board of Allergy and Immunology. A wide variety of opportunities is available for training in clinical medicine, as well as laboratory research, and all clinical fellows will be expected to participate in both of these spheres over the course of the fellowship.

Application Requirements

An application packet includes:

  • ERAS application
  • CV
  • Personal Statement
  • Three letters of recommendation
  • USMLE scores
  • Photo
  • ECFMG certification (for foreign medical graduates)

Application deadline: September 1st

Interviews are held in September and October

One year of the training program is dedicated to research with additional time interspersed in the remainder of the fellowship. At least 25% of the resident's time is allocated to research per ACGME requirements. Each resident is required to present a scientific abstract at a national meeting and to submit peer-reviewed publications. Further, they are strongly encouraged to apply for national and regional awards and grants. This is another measure of the quality of research.

National Meetings: Fellows are encouraged to submit abstracts and attend the ACAAI meeting in the fall and the AAAAI meeting in the spring. Texas also holds its own state meeting annually as well. Each fellow will be able attend at least one of these meetings annually.
