●        Step 2: Undergraduate Education and MCAT

Start your educational journey with a four-year bachelor’s degree and successfully complete the MCAT (Medical College Admission Test). Research and understand the specific prerequisite courses required by medical schools, as these requirements can vary.

●        Step 3: Apply and Complete Medical School

Apply to Caribbean medical schools once you have met the prerequisites and completed the required courses. The application process is competitive, so early research and consultation with academic advisors are essential. Medical school typically spans four years, with the first two years focused on fundamental science courses and the latter two years involving clinical rotations. The first United States Medical Licensing Exam (USMLE) is usually taken in the second year of medical school, and there are a total of three USMLE exams. Most students take the second exam during their fourth year before entering residency.

●        Step 4: Residency Training

Residency marks a significant phase where hands-on training and practical application of skills acquired during medical school commence. During this period, the third and final USMLE is taken. Aspiring allergists must complete a residency program in either internal medicine (three years) or pediatrics (three years). To conclude residency, candidates should achieve board certification through either the American Board of Pediatrics (ABP) or the American Board of Internal Medicine (ABIM).

●        Step 5: Fellowship in Allergy and Immunology

For individuals seeking specialization in allergy and immunology, the next step is to apply for and complete a two-year fellowship program. This fellowship offers in-depth training and expertise in managing allergic and immunological conditions.

●        Step 6: Board Certification and Licensure
