I ran out to the doc to get my flu shot today. Getting a flu shot is nowadays even available at drug stores and at supermarkets here in the USA (I wonder why .. maybe they hope people that come in will buy $20 of groceries as well?). Even so, less than half of the population get their shot every year. Flu costs the USA more than $87 billion annually, including an estimated $10.4 billion a year in direct medical expenses and an additional $16.3 billion in lost earnings annually, according to a report released recently by the Center for Disease Control (CDC) Foundation. I went with the standard needle, stuck into the muscle of my arm. For the squeamish there is a fancy intra-dermal shot that uses a tiny 1/16-inch long micro-needle to inject the vaccine just under the skin.
