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.
Therefore, when calculating costs and labor for 1000 square feet of attic space, the average homeowner should expect to pay: 1  $500 - $1,000 for materials. 2  About $100 for equipment rental (which is sometimes offered for free with the purchase of a set amount of insulation) 3  For a total of $600 - $1,200.
