ARLINGTON HEIGHTS, Ill., Oct. 9 (UPI) -- People who experience an allergic reaction to a vaccine should investigate it further rather than avoid future immunizations, U.S. researchers said.
Of the 235 million doses of vaccines administered annually in the United States, only one dose per million causes a serious medical reaction and fatalities from those reactions are rare, researchers from the Illinois-based American College of Allergy, Asthma and Immunology said in a release Friday.
Skin reactions and fever are common after vaccinations and should not be used as a reason to avoid future vaccinations, said Dr. James Li, professor of medicine at the Mayo Clinic, Rochester, Minn.
"I believe anyone with this concern should check with their doctor and consult with an allergist," Li said.
Reactions to vaccines most often are caused by vaccine components, such as egg protein or gelatin, rather than the immunizing agent itself, Li said.
