Describe the production of influenza vaccine using chicken eggs. What are the limitations to this production method?
Homework Answers
By using chicken egg two type of influenza vaccine ara made that is inactivated killed vaccine or live attenuated vaccine. Virus are injected into the fertile chicken egg and kept for incubation for 2 to 4 days to allows viral replication in cell. After incubation virus containing fluid isolated from egg. Then for killed vaccine virus are killed and inactivated and virus antigen is purified in this way killed inactivated vaccine prepared. In case of live attenuated vaccine virus particle are attenuated by diffrent chemical method that is their disease causing ability destroyed.
Limitations are; Only fertile egg required for production, sometime get contaminated due to improper technique. Isolation is also difficult task. Sometime virus not replicated. Chances to infect person is high. These are the limitation of influenza vaccine by chicken egg.

Chicken Eggs A farmer focusing on the production of eco-friendly chicken eggs collects the following data about his output In a sample of 50 eggs, the farmer finds the average egg to weigh 47 grams The standard deviation of the egg weight is 2 grams and the distribution of weights resembles a normal distribution reasonably closely The farmer can sell the eggs to a local distributor However, they have to be in the interval between 44 grams and 50 gramsI.e,...

Researchers conducted a study to determine an initial estimate for the effectiveness of the influenza vaccine during the 2014-2015 influenza season (Flannery et al., 2015). The participants in the study were randomly selected from 2321 individuals with respiratory illness from five U.S. states. In Pennsylvania, the study found that, out of 461 patients with acute respiratory illness, 210 had received the influenza vaccine. which procedure should be used for calculating a 95% confidence interval for the vaccinated patients in Pennsylvania,...

2. There are two industries, hatching and laying, and two goods, eggs and chick- ens. The price of an egg is l; the price of a chicken is p. The hatching industry produces y chickens using x eggs, which it buys from the laying industry. Its production function is yi-4(x1)2. The laying industry produces x2 eggs using chickens, which it buys from the hatching industry. Its production function is x,-(y2)1/2. (We assume away any consideration of time lags, non negativity...
