create a scientific argument of one to two paragraphs that support or oppose the current flu vaccine recommendations.
OlgaM077 [116]

Answer:

Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.

Explanation:

Flu vaccinations <u>reduce the risk of flu illness by over 50%</u>. This makes this process extremely important and fundamental for all human beings as they <u>not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people</u>, especially children and older adults who possess a greater risk of developing flu complications.

<u>The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell</u>. However, if a person has not been vaccinated, <u>the virus will attack the healthy cells</u> because there is an absence of antibodies that prevent this process.
