Every year, influenza is responsible for the illness of thousands of people in the United States. In some more serious cases, it results in hospitalization and even death, especially in the very old, very young, or those with compromised immune systems. One of the most effective ways to prevent this is through immunization. When it comes to understanding the importance of flu shots Mobile AL patients will find the following information helpful.

An inoculation against the influenza virus works by stimulating the production of antibodies that will help destroy the microorganism if it enters the body. Within two weeks of receiving the vaccine, the antibodies will form. Flu viruses are classified as either A or B influenzas, most immunizations protect against a combination of these strains.

The most common vaccines are classified as either trivalent or quadrivalent. Recipients of a trivalent vaccine are given protection from three strains of flu, HINI and H3N2 which are "A" viruses and also one "B" virus. Those who get a quadrivalent vaccine receive the same protection, along with the addition of one other "B" influenza. There is also a nasal spray version of some vaccines, which can be given to people from 2 to 49 years of age.

The nasal spray vaccine is considered the first choice for healthy children between 2 and 8 years old, but if not available, a regular injection should be administered. Others will receive either a regular vaccine, high-dose vaccine, or intradermal injection. A doctor can recommend which option is best.

Precautions must be taken to ensure that each patient is given the appropriate vaccine for his or her age. High-dose vaccines are indicated for people over age 65, and intradermal shots are intended for those who are between 18 and 64 only. People with an allergy to eggs, will need an inoculation that is prepared using a cell culture instead.

Generally the flu season in the United States starts in October and concludes in May. Healthy people from the age of six months and up are advised to get immunized each year, ideally before the season begins. Manufacturers usually start shipping out vaccines as early as August and continue to distribute them throughout the fall and into the peak flu period, which most often happens in January.

There are many places where one can receive a flu vaccine including the doctor's office, public health clinics, health centers at educational facilities, and sometimes in schools, or at the work place. It is important for everyone of age to get vaccinated each year due to the fact that immunity naturally declines after each shot, and because strains of influenza tend to change over time, altering the inoculations from year to year.

Sometimes a person may still get the flu even after being vaccinated, although it will greatly reduce the severity of the illness. Side effects are noted in some individuals following immunization as well. Those receiving an injection may develop a low-grade fever and soreness at the injection site, and those who are given the nasal spray may experience a runny nose, sore throat, or headache, but these short-lived symptoms are still better than getting very sick with influenza.
