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.
1 This means that the 240 square feet of ceiling/attic will cost between $360 and $720 to complete; 2  The Walls-wall insulation will require an R15 to R18 value, and this depends upon the presence of exterior sheathing beneath the siding of the home. Should the homeowner require the services of an insulation contractor who uses blown cellulose materials, the costs will double to roughly $3 per square foot instead. 2  This means that the 240 square feet of ceiling/attic will cost between $360 and $720 to complete;
