Children who suffer from food allergies declared safe to get a flu vaccine during preventive action. This was stated by a team of researchers from the Johns Hopkins Children’s Center, United States, because many parents are concerned with the security of flu vaccines that contain egg. In the United States is currently estimated 3 percent of children suffer from egg allergies.
“Many parents worry on allergic reactions due to the flu vaccine so that they do not want their children vaccinated. But in the flu season, the impact of influenza disease is greater than the possibility of allergic reaction. In fact, children who suffer from egg allergies can safely be vaccinated,” explained Dr. Robert Wood, director of allergy and immunology section of the Hopkins Children’s.
The issue of allergic reactions is increased in the middle of this year than ever before. This is partly because the U.S. health department for the first time requires all children aged 6 months to above must obtain a flu vaccine before the flu season this year.
Previously, the flu is only required to be vaccinated children with certain medical conditions, such as children with asthma, diabetes, heart disease or neurological disorders and immune system.
Although several types of vaccines are made with non-allergic materials, but not the flu vaccine. In response, Woo said the children who are allergic to eggs are advised to perform allergy testing before receiving the vaccine. The goal is to find out the severity of allergy and saw signs of antibodies against gelatin or egg protein that is usually used in making vaccines.
Anti-allergy drugs, such as antihistamines and corticosteroids may be given before the implementation of vaccination to reduce allergic reactions.
In a study conducted Woo and his team, known allergic reaction due to the flu vaccine are rare, ie, only 1-2 patients per one million. Allergic reactions that may arise due to the vaccine include swelling, coughing, sneezing, low blood pressure, nausea, diarrhea, and itching. Can also occur severe allergic reactions, which can be life-threatening anaphylaxis.
Allergic reactions usually appear 1-2 hours after the vaccine. The reactions that occur several days later revealed mild and do not endanger the health of children.
