The flu shot is often neglected, according to the centers for disease control, only 37% of Americans recieved their flu shot in the 2016-2017 season. The flu shot changes every year to keep up with the varying proteins on the virus. The vaccine is important for the recipient's protection against the flu, as well as everyone surrounding them. Certain individuals are vulnerable to disease, they are the elderly, infants, those recieving chemo-therapy, and individuals with an autoimmune disease. Individuals who are immunocompromised cannot get vaccines; vaccines should be administed several weeks before the individual becomes immunocompromised (if that is possible, such as several weeks before chemo-therapy). These immunocompromised individuals can be protected through herd immunity; when the majority of a population is vaccinated, the virus has a hard time infecting individuals. Therefore, everyone should keep up with their flu vaccines to prevent contraction of the virus for themselves, as well as immunocompromised individuals who cannot recieve the vaccine and rely on others for protection.

Consider breaking the first sentence up into an initial statement sentence and a supporting sentence.
CDC
The Center for Disease Control is a title and should be capitalized
topic sentence
You could add a topic sentence as I was a little confused, instead of starting with facts. Also, there are a few typos here and there, as well as the Center for Disease Control should be titled.
