Because the measles and mumps vaccines are made by growing the virus in the cells of chicken embryos, children with egg allergies used to be advised not to get the vaccine. However, studies have found that even children with severe egg allergies can receive this vaccine without a greater risk of side effects.
Width 1st, Length 2nd. Please note, on inside the window measurements, the factory takes deductions in order to fit inside that window opening. For the width (always do width first) measure the top, middle and bottom and go with the narrowest measurement (we don't want these sticking to the sides).
The length is traditionally the longer of the two sides, and the width is the shorter -- except for squares, where length and width are the same. The unit of measurement you use depends upon the size of the space. You might use inches to measure a small space and feet or yards to measure a larger space.
