Different kinds of influenza vaccinations and their efficacy in the prevention of flu

Flu is a very small word, yet it can lead to severe devastations and even deaths of many.  In 2013, over 3600 people died from influenza all over the world. To protect yourself and control the spread of influenza, you must ensure taking vaccines for flu, which are available as a shot or as a nasal spray. These vaccines have a very safe track record, and though there may be some mild side effects after taking flu vaccines, the Food and Drug Administration and the Centre for Disease Control and Prevention closely regulate the safety of the seasonal influenza vaccines.

How does the influenza vaccine work

The seasonal vaccines for flu can provide protection against the flu viruses that would be most prevalent during the upcoming flu season. The conventional flu vaccines also known as trivalent vaccines are required to shield against three types of flu viruses, viz., Influenza A called the H1N1 virus, Influenza B and another type of Influenza A called the H3N2 virus. There are also flu vaccines that are effective in providing protection against four kinds of viruses and are known as quadrivalent vaccines. It is important to know more about these different flu vaccines.

What kinds of flu vaccines are there

There are several types of flu vaccinations available for the 2015-2016 influenza season. Though there are primarily two kinds of flu vaccinations, there are a few variations, which make a particular type of vaccine more effective than the other types.

Trivalent flu vaccine: It is already known that the trivalent vaccines for flu can protect against two types of influenza A virus and one type of influenza B virus. There are different variations in trivalent flu vaccines treatment. The Standard Dose trivalent shots which are more commonly known as IIV3 are made from a virus grown in the eggs. Various flu shots can be given to people belonging to varying age groups, but most of them are administered with a needle. A high-dose trivalent shot is given to people aged over 65 years. People aged between 18 and 65 years can be given a trivalent flu vaccine shot that contains virus grown in cell culture.

Quadrivalent flu vaccine: The quadrivalent flu vaccine shots that are mostly given to protect from two types of influenza A and B virus have the treatments, including an intra-dermal trivalent shot where the shot is injected into the skin instead of the muscle with the help of a much finer needle. It is very effective for people aged between 18 and 64 years. In place of the intra-dermal shots, a quadrivalent nasal spray vaccine can also be given to people aged between 2 and 49 years. The flu immunisation costs vary from place to place and are mainly dependent on the type of treatment administered.

The effectiveness of the influenza vaccinations may vary from year to year as well as among various age groups of people, but there are a few sure shot benefits of flu vaccines for which it is important to get your dose of flu shot every year.
