The vaccination for the flu by injection or the flu shot is readily available every year to protect adults who are at risk for flu and its potential complications. Always bear in mind that the flu can be unpleasant, but if the individual is healthy, it typically clears up on its own within a week.
It is sad to note though that the flu can be considered severe in some individuals such as those aged 65 and over, pregnant women, children and adults with weakened immune systems and those who have underlying health conditions. Those who are included in these high-risk groups are more likely to develop potentially life-threatening complications of flu such as pneumonia. This is why it is recommended to get a flu shot yearly for protection. The flu shot is given every year to adults over 18 years old who are at risk for flu and children 6 months up to 2 years at risk for flu.
What is the flu nasal spray vaccination?
Always bear in mind that the flu vaccine is regularly given in a nasal spray form yearly to healthy children 2-4 years and those aged 2-17 years old at high risk for flu.
Effectiveness of a flu shot
Always bear in mind that the flu vaccine is the ideal protection against an unpredictable virus that can trigger undesirable sickness among children as well as severe illness and death among high-risk groups including the elderly, pregnant women and those who have underlying health conditions.
Based on studies conducted, it was discovered that the flu shot works and also works by preventing the disease. Just remember that this will not stop all the flu viruses and the level of protection can vary between one individual to another. Remember that this is not a guarantee that the individual is free from flu, but if the individual acquires the condition after vaccination, it is likely to be mild and short-lived than it would have otherwise been.
Over time, protection from the injected flu vaccine steadily decreases and the strains of flu often change. Some of the new flu vaccines are produced every year which is why it is vital to receive the shot every year.
What are the potential side effects?
The serious side effects of an infected flu shot are considered rare. The individual might have a slight increase in the temperature or fever and aching muscles for a couple of days after receiving the shot and the arm can be quite sore where it was injected.
When to receive the flu shot
The ideal time to get the flu shot is in the autumn season, but do not worry if the individual missed out on it since he/she can get the shot later in winter.
