We are also working with nursing homes to insure that they have vaccine for their residents. The supply of flu vaccine this year is expected to be approximately equal to what was distributed last year, although some of it will not be available until later than usual. The CDC anticipates distribution of approximately 75 million doses of vaccine, although as many as 18 million doses will not be available until December. Whether there will be a shortage of flu vaccine will depend on whether there is an increase in the demand for vaccine. The Advisory Committee on Immunization Practices recommends that everyone aged 50-64 get a flu shot, but anyone who wants to avoid being a target of influenza should consider being vaccinated.
Flu is caused by viruses that infect the respiratory tract.
Flu symptoms include fever, cough, chills, sore throat, headache, muscle aches, and extreme fatigue. Although nausea, vomiting, and diarrhea sometimes occur during a flu infection, such symptoms are rarely prominent.
