DO YOU KNOW ENOUGH TO DECIDE IF YOUR FAMILY SHOULD GET FLU SHOTS?
Vol. 6 Issue 132
With flu season soon upon us, you should consider the following information before deciding if your family will get the flu shot.
Each year a “flu shot” is prepared based on the guess-work of Federal health agency officials, who try to determine which of three flu strains will be prevalent in the U.S. during the following year, so they can select which strain to include in the vaccine.
The flu vaccine is prepared from fluids of chick embryos that have been inoculated with a specific type of influenza virus. The virus is then activated with formaldehyde and preserved with thimerosal — a derivative of mercury.
If health officials select the correct strain of the virus, the vaccine is thought to be 70-80% effective in preventing the flu in healthy persons under 65 years of age — the efficacy drops to only 30-40% among those over 65 years. Health officials don’t always make the right prediction, which lowers the effectiveness for that year.
According to the National Vaccine Information Center’s fact sheet, “Influenza is a respiratory infection that produces fever, chills, sore throat, muscle aches and cough.” Symptoms can last for a week or longer and can be deadly for the elderly or those suffering from diabetes, kidney dysfunction and heart disease.
The vaccine does not protect against throat, respiratory, gastrointestinal and ear infections caused by bacteria or other kinds of viruses; it serves only to provide temporary immunity against the three specific viral strains included in the year’s vaccine.
Adverse reactions typically being within 12 hours of vaccination and last for several days; these include fever, fatigue, painful joints and headaches. The most serious reaction, which occurs within two to four weeks of vaccination is Guillain-Barre Syndrome, which is characterized by muscle weakness, unsteady gait, numbness, tingling, pain and sometimes paralysis of one or more limbs or the face.
According to the Center for Disease Control and Prevention, those at high-risk include any person who is sick with a fever, has an impaired immune system, has an egg or mercury allergy, and has a history of Guillian-Barre Syndrome. Pregnant women should be aware the flu vaccine contains the mercury-derivative thimerosal, which has been linked to causing brain damage and developmental delays in babies whose mothers were exposed to high levels of mercury during pregnancy.
