Why do we need a new flu vaccine every year?
The flu changes each year
Though it is commonly referred to simply as ‘the flu’, the actual virus going around each year is always different. It is an ever-changing virus. In response to this, medical professionals need to update the flu vaccine each season, which protects us from the new strains.
Your antibodies grow weaker over time
Flu vaccinations are needed each year to ensure you have continuous protection. Though you may have received a flu vaccine last year, your body’s immune system from previous vaccinations gradually decreases over time.
By the time flu season comes around, your body’s immunity to it is virtuality non-existent. By getting a flu shot each year, you are protecting yourself from new strains, whilst also boosting your continuous protection.
The flu vaccine is the most effective way to prevent illness.
It really is that simple. The CDC estimates that an individual who receives a flu vaccine reduces their risk of contracting the illness by up to 61%!
Immunization is an easy and proactive way to protect yourself from the discomfort. However, if you do catch the flu after immunization, various studies show that the vaccine will still provide you with various benefits.
The vaccinations available to the public typically protect you from three to four different strains of the flu! The antibodies that your body developed from your sickness may only protect you from that one strain- leaving open the possibility of getting sick again.
Getting vaccinated helps protect your loved ones
This includes others who are more vulnerable to serious flu illness, like children and senior citizens. By vaccinating yourself, you are less likely to transmit influenza to others. This means you are not only keeping yourself healthy but the ones you care about most!
