Unlike last year's vaccine shortage and the prohibitive lines to receive vaccinations, this year flu vaccines were ready in abundance and in record time. In fact, as Fox News reports, many drugstores offered vaccines in conjunction with their back-to-school sales.

Another difference this year is that the CDC is recommending everyone be vaccinated. This protects not only those most at risk for complications from the flu, but also provides a ‘circle of protection’ by keeping stronger individuals from spreading the flu. As CDC physician Dr. Anne Schuchat puts it, ‘Influenza is serious, and anyone, including healthy people, can get the flu and spread the flu. Flu vaccines are the best way to protect yourself and those around you.’

This year's vaccine includes three strains of influenza: last year's swine flu, another strain of the H3N2 family that has emerged, and a Type B strain. A high-dose version of the vaccine is available for those over 65. Other varieties of the vaccine in terms of dispensation include the nasal mist, which is recommended for those between 2 and 49 who have no underlying health conditions and who aren't pregnant. Preservative-free vaccines are also available, and often recommended for young children or pregnant women.

Remember, those with asthma are considered high-risk for developing complications from the flu, and should be sure to receive vaccinations. Those who are allergic to eggs, however, must take precautions when getting a flu vaccine because of the way the vaccine is prepared. If you fall into this category, be sure to discuss this with your doctor.
