The Missouri Department of Health is advising anyone interested in reducing the risk of getting the flu to get a shot. And, the Department is making it clear there is plenty of vaccine available for anyone who wants it. Flu season got a late start, in part because of the relatively warm temperatures in November and December. People were spending more time outdoors and away from crowded offices and rooms where germs are likely to be found. The Department says those in “at risk” categories should consider getting vaccinated. They include the elderly, those who are at least three months pregnant during the flu season, those with chronic health problems, and health care workers.
