Flu vaccine

Now is the time to get your flu vaccine. The 2013- 2014 flu season is here for the Northern Hemisphere. Los Angeles has reported it’s first flu case early September (Click here). New York city residents are surprised that flu season has already arrived and reaching people before their scheduled flu vaccination date. The first Los Angeles case is an H1N1 which is in this year’s flu vaccine combination to protect those vaccinated this season. The New York city strain has yet to be reported. Fortunately, the flu vaccine of 2013 – 2014 has either three flu strains (trivalent) or the newly introduced four flu strains (quadrivalent) described more in detail below. (Read more)

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.


“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.”


Not all flu vaccines are right for everybody
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. You may want to discuss with your doctor options suchas a brand name Flumist, which is a flu vaccine via a nasal spray.  Flumist includes live flu virus, unlike traditional flu vaccine which includes killed flu virus.  A healthy immune system is important when receiving a live flu virus.

The needle method of delivery of Flu Vaccine

The needle method of delivery of Flu Vaccine

Sometimes, people prefer a flu vaccine delivered via a nasal spray instead of a needle or a patch of latex – coated microneedles. Discuss options with your doctor.

Also, you may want to be aware of egg or latex related allergies (click here for “Flu vaccine and egg allergy‘).  Traditionally, flu vaccines are developed in eggs.  The latest vaccine options include one developed in insects instead of eggs (Read more)

Can you get the flu after getting the flu vaccine? Yes, if you are exposed within a short period of getting the vaccine. The body’s immune system needs time to learn how to recognize the new flu vaccine composition. You may want to know that if your vaccine composition (Read more) is the same as the flu vaccine you took last year. If it is the same, you may not get a fever after you take the flu vaccine, since you already have the immunity.  However, if it is different, then there is a small chance you may get a fever, since your body’s immune system trains to defend you.  Also, if you are exposed to a new flu strain not included in your flu vaccine composition then, you might get the flu. This year, there is a quadrivalent flu vaccine option (see below) unlike previous years which included only the trivalent option (see below). Every year the types of flu strains that infect us is different, some more virulent than others. The World Health Organization (WHO) tries to recommend the best cocktail of flu virus strains to protect us. However, the flu virus is able to outsmart the human by evolving a new strain to break down our immune defences.

Adverse Effects: There are adverse effects from the flu vaccine and information on this is available from your physician or on local government health sites, such as the CDC in the USA and the World Health Organization (WHO) worldwide sites and the global action plan.

Flu Vaccine Composition: The Northern Hemisphere and Southern Hemisphere have different patterns of flu infection. The WHO decides the flu vaccine composition twice a year. In February for the Northern Hemisphere and in September for the Southern Hemisphere.

The flu vaccine was traditionally made in eggs and hence the article on egg allergy here. However, with the awareness of egg allergy rates, there has been an effort to find an alternative to grow the flu vaccine. In the 2013-2014 quadrivalent flu vaccine composition lies the answer since it is developed in insects and not eggs.

What is Flu or Influenza and what does the Flu Virus look like?
The Flu Virus is a tiny micro-organism that manages to outwit the human by evolving a new strain every year to evade the human immune fortress. The Flu Vaccine was developed to fight the pandemic flu of 1918 (see history of the flu vaccine) and since then, researchers have realized that to fight the flu viruses ability to change itself, a new matching vaccine composition has to be developed every year. The story of this wily virus and the research war against it, is worth reading. When you have the time, do send a thank you note to the flu scientists who have devoted their energies towards avoiding the next flu pandemic. Do keep in mind, that not everybody gets the flu. Some will never get the flu and they hold a clue which researchers have to discover. However, people can die from the flu, as shown by the numbers in the devastating 1918 pandemic and in subsequent decades. The flu vaccine can prevent most of the deaths.
