Why are animals vaccinated?

What will be an ideal response?


The prevention of a disease is nearly always less expensive than treating animals once they have
become infected. A good disease-prevention program should include vaccination of animals.
Vaccination is the injection of an agent, such as a modified disease organism, into an animal to
immunize it against a specific disease.

Vinyl chloride is a colorless odorless gas used in the production of PolyVinyl Chloride (PVC) plastics and in numerous industries. Vinyl chloride is also a known human carcinogen and the US EPA’s Maximum Contaminant Level (MCL) in drinking water is 0.002 mg/L or 2 ppb. The vinyl chloride concentration in the soil outside of a plastic factory is 0.007 mg/kg, and the soil has a 15% organic content. Vinyl chloride (chloroethene) has a reported octanol-water coefficient equal to 4. Estimate the organic carbon normalized partition coefficient, Koc, using the estimation procedures based upon equations 2.73 and 2.74 and the sediment/water partition coefficient. Use the sediment/water partition coefficient to predict the possible equilibrium concentration of vinyl chloride in the groundwater.
