I have allergies and asthma. If a respatory attach comes I am terribly sick for a month. Once I was sick 3 times in 18 months...that's enough of that bad luck! You can bet that I get a flu shot.Upon the advice of the pharmacist I took the regular shot not the newest one that was untried.Also I wash hands when I come in the house immediately. Its a good habit to develop.Hand knit wool socks in winter, shawl/scarf to increase warmth over the shoulders of a coat...bundling up for sure.
