Generally, Mayo Clinic and Cleveland Clinic are fairly reliable in learning about medical conditions, even beyond allergy and asthma.

A good place to start is the AAAAI, a professional group of allergists. For more information on allergic conditions:

Allergy & Asthma

• American Academy of Allergy, Asthma and Immunology
  A professional group of allergists.
• American College of Allergy, Asthma and Immunology
  A professional allergist’s organization, with a bit more practical slant.
• Allergy and Asthma Network/Mothers of Asthmatics
  Probably the best lay resource for allergy and asthma.
• American Lung Association
  Maryland Chapter
• Asthma and Allergy Foundation of America
  Excellent lay organization
• National Jewish Medical and Research Center
  National Jewish Medical and Research Center is a very large respiratory medical center in Denver.

Food Allergy

• The Food Allergy Network
  A very well-edited site by lay organization; contains excellent practical advice.

• Allergy and Asthma Network/Mothers of Asthmatics
• American Academy of Pediatrics
• Food Allergy Network for Kids

General Medical

• Mayo Clinic
• Cleveland Clinic

Pollen

• Maryland Pollen and Spore Report
  Sue Kosisky at Walter Reed Medical Center is a national expert on pollen; she’s only a few miles “upwind”, and we compare our data every year. Most websites advertising pollen given only computer generated forecasts; true readings can only done by hand. There are only a handful who read pollen in Maryland. Like politics, all pollen is local.

Vaccines

• Flu Vaccine and People with Egg Allergies

Others

• U.S. Food and Drug Administration
• Johns Hopkins Division of Allergy and Clinical Immunology
• U.S. National Institutes of Health Clinical Trials
