Accidental tenfold overdose of influenza vaccine: a clinical and serological study. Matzkin H, Nili E. We analyzed the effects of an accidental tenfold overdose of influenza vaccine that was given to 31 young healthy members of the Israel Defense Forces. A clinical workup and serological tests were performed after the vaccination in order to quantify any side effects or complications and relate them to immunogenicity of the vaccine administered.
Add attic insulation to lower heating and cooling costs by as much as $600 per year. Save about $600/year by boosting the amount of attic insulation from R-11 to R-49. Depending on the type of materials you use, figure on paying an insulation contractor about $1,500 to insulate an 800-square-foot attic, which pays back your investment in three years. Youâll spend about half that to do the job yourself.
Now that you've air-sealed your attic and basement, check your attic insulation levels and add more if necessary. The attic is the easiest place to add insulation to improve your comfort and the energy efficiency of your home.
