MMR vaccine should be administered for both doses. The first dose of MMR vaccine should be administered routinely at 12 to 15 months of age. Children who receive measles-containing vaccine before 12 months of age should receive additional doses of MMR when they are 12 to 15 months of age and at 4 to 6 years of age. second dose of measles-containing vaccine, regardless of the age when given, is highly effective in inducing immunity in children who did not have a response to the first dose (provided the interval between doses is â¥1 month).
Quick Answer. The length of time it takes to bake a chicken depends on the temperature of the oven as well as the size of the chicken being used. If baked at 375 degrees Fahrenheit, a whole chicken that weighs 2 1/2 to 3 pounds should be cooked for one hour to one hour and 15 minutes. Fifteen minutes should be added to the cooking time for every half-pound.
Hence, if you want to prepare a chicken roast to serve 4 â 5 people, you would require about 5 lb meat and a total cooking time of 1 hour 50 minutes. Some people, however, prefer to roast the chicken on high heat of about 450 degrees F for the first and last 15 minutes (a total time of half an hour).n order to prepare roasted chicken, you need to first preheat the oven to 350 degrees F. The time needed to roast a chicken varies with the thickness of the meat. A large chicken could even take about 2 hours to fully get roasted.
