It is time for your 2013-2014 flu vaccine. However, do take your doctor’s advice before vaccination. Certain flu vaccines are not recommended for all ages. For example, CDC recommends that one brand of inactivated flu vaccine called Affluria, should not be given to children 8 years of age or younger. A related vaccine was related with fever and fever – related seizures in young children in Australia. More about side effects below. Young children who get inactivated flu vaccine and pneumococcal vaccine (PCV13) at the same time may be at increased risk for seizures caused by fever. Ask your doctor for more information. Tell your doctor if a child who is getting flu vaccine has ever had a seizure. You may also read “Why am I feeling fatigued after taking the flu vaccine?”
Avoid Pain Reliever with Flu Vaccine
Although your first reaction would be to take a fever or pain reliever along with the flu vaccine – you may want to avoid this action. Common pain relievers dilute the effect of the vaccine. Click here to read the views of the University of Rocherster Medical Center. Quote
“What we’ve been saying all along, and continue to stress, is that it’s probably not a good idea to take common, over-the-counter pain relievers for minor discomfort associated with vaccination,” Phipps said. “We have studied this question using virus particles, live virus, and different kinds of pain relievers, in human blood samples and in mice — and all of our research shows that pain relievers interfere with the effect of the vaccine.”
Egg and/or latex allergy?
What if you have an egg and/or latex allergy? Consult your doctor. The answer is in this previous article. However, there is a major update for individuals with egg allergy waiting to be vaccinated – Flublok. In 2013, FDA has approved Flublok, for 18-49 year old, which is not developed in eggs but in insects. Hence, Flublok may be suitable for adults (but not children, teens and seniors) with egg and/or latex allergy. Traditionally, the flu vaccine has been developed in eggs. To learn more you may read a previous article, “Tracking the history of the development of the flu vaccine”, by clicking here. The ability to develop the flu vaccine in insects instead of eggs is heralded as a boon to egg allergic individuals. However, since it has been newly introduced in 2013, it remains to be clinically tested in individuals other than adults and hence, is not yet FDA approved in children, teens and seniors, since their immune system is different than a typical healthy adult.
Please, discuss with your doctor. It is highly recommended to take the flu vaccine to avoid hospitalization and other secondary complications from a flu infection. It is highly contagious. Certain age groups are more susceptible than others. The Centers of Disease Control of USA reports a total of 12,343 hospitalizations that occurred from October 1, 2012 through April 30, 2013, which translates to a cumulative rate of 44.3 influenza-associated hospitalizations per 100,000 people in the United States. The total number of influenza-associated pediatric deaths reported to CDC for 2012-2013 was 146 in USA. While the vast majority of the tested virus samples (>99%) showed susceptibility to the antiviral drugs oseltamivir and zanamivir, some varieties showed resistance.

Why do I feel fatigued after my flu vaccine?
The vaccine composition is changed every year. The WHO meets twice a year to discuss the varieties of flu strains causing flu infections and hopes to include the most “popular” strains in the flu vaccine composition (see below for for the 2013-2014 composition). However, the vaccine can accomodate a maximum of three to four flu strains. There might be a new flu strain that emerges later in the year. There might be a fifth or sixth flu strain also causing infections. The flu vaccine assists an individual in easing the “suffering from symptom” period. Therefore, a person who has the vaccine can still get the flu from a flu strain not included in the vaccine but the symptoms will be weaker. This is because the flu strains differ from each other very slightly and most of their characteristic proteins are included in the vaccine, hence “teaching” the body’s immune system to be ready to fight the flu infection.
There can be a slight fever and other side effects (see below) after the flu vaccine. The symptoms would start right away and last 2 to 3 days. This might happen if the flu vaccine composition includes one or more flu strains that were not included in the previous year’s vaccine composition. If the individual has never been exposed to 1 or more of the flu strains in the vaccine, the immune system might react with symptoms like the flu. It is the immune system getting ready. The individual does not get flu from the inactivated flu vaccine and the live flu vaccine is too weakened to cause the flu. You may also read “Why am I feeling fatigued after taking the flu vaccine?”
