Mistakenly undermined as non-threatening, influenza infects thousands of Americans every year, landing some of them in the hospital, or in the most serious cases, it can cause death. Young infants, elderly people, and those with impaired immunity are most susceptible to developing serious complications from this potentially fatal viral illness, however with routine seasonal flu shots Mobile AL influenza cases can be greatly reduced.
When someone receives an influenza vaccine, it stimulates the production of antibodies against these viruses. It typically takes about two weeks for this immunity to develop. Influenza viruses are categorized as either "A" or "B" strains, and most vaccines provide protection against a combination of these viruses.
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.
Certain types of vaccinations are indicated based on the age of the patient. Only those over the age of 65 can be given a high-dose vaccine, while intradermal injections are to be used on people between the ages of 18 and 64. Many vaccinations are prepared with eggs as a base, so those who are allergic to eggs will need an alternative such as vaccines prepared in cell cultures.
October through May is the flu season in the United States, although cases may occur outside of this time period. All people from the age of six months up should get vaccinated before this time, unless directed otherwise by their physician. Vaccine manufacturers normally start shipping vaccinations out in August and continue to do so throughout the fall and into the winter when the greatest number of flu cases occur.
The importance of getting vaccinated against the flu is highly publicized in most communities with clinics being set up in schools, workplaces, and college health centers. People can also choose to get their shots at the doctor's office or at a public health clinic. Annual immunization is necessary as it typically only provides a year's protection, and also because predominant viral strains tend to change over time.
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.
