influenza flu vaccination cold covid-19

The effectiveness of flu vaccines has been a hot topic for every year. In the 21st century, where we started to live with pandemics, the success of vaccination against diseases is obvious. Vaccines have led to the end of many diseases that existed in previous years. The flu vaccine is different from other vaccines due to the type of virus it affects. The most important difference is that the flu vaccine must be repeated seasonally. Nowadays, when diseases are increasing, it is important to understand and use the flu vaccine well.

Vaccination has also gained importance in this period when the effect of science increases day by day in combating epidemic diseases. Flu vaccines are frequently used to create a protective shield against flu in many different countries of the world. Although the effectiveness varies depending on the years in the studies conducted every year, the flu vaccine provides protection between 40% and 60% in the studies.

The effectiveness of the flu vaccine varies from season to season. However, it can be said that there are two main factors that determine the effect of the vaccine.

1- Characteristics of the vaccinated person (health status, age, physiological characteristics, etc.)

2- The similarity of the vaccine used with the influenza virus common in the society.


The increase in the similarity of the flu vaccine to the common virus types in the society has increased its effect. But the characteristics of the vaccinated person are also an important factor affecting which type of vaccine should be used.

  • The flu vaccine can ensure that we are not infected with the virus.
  • The flu vaccine can reduce the risk of children, adults and the elderly to be hospitalized for the flu.
  • The flu vaccine is an important protection tool for people with chronic diseases.
  • The flu vaccine helps to protect the woman from influenza during pregnancy.
  • It has been demonstrated in many studies that the flu vaccine reduces the severity of the disease in people who are vaccinated but are infected.
  • Vaccination of many people lowers the risk of pandemics in the community.

Seasonally applied flu vaccines are produced to protect against infection by three or four viruses, depending on the type of vaccine. Contrary to common belief, influenza vaccines are not effective in preventing other diseases with flu-like symptoms. Many viruses other than influenza that cause flu can cause similar symptoms. (For example, viruses that cause colds.) Having a flu shot has no effect on these viruses. However, being vaccinated against influenza will often help you to have a mild flu, making it easier for the doctor to diagnose.

The defense power of the shield provided by the flu vaccine varies according to the type of vaccine used. In addition, no type can be determined as the best type of flu vaccines. The type of vaccine to be administered should be determined according to the common flu virus in the society. Vaccination made after the common virus type is determined greatly increases the effectiveness of the vaccine.


Considering all this information, it is vital that most of the population have the flu vaccine, especially before the flu season. Before the flu epidemic increases, it is important for children, adults and the elderly to get the flu vaccine in consultation with their doctors. Doctors are the most competent people in determining the most appropriate type and subtype of the flu vaccine, which we have discussed throughout the article. You can get vaccinated and protect your health by consulting your doctor before the epidemic period.
