In veterinary medicine, most vaccines are developed against viruses; some protect against specific bacteria or toxins. Hence, they are capable of replication independent of the chromosomal DNA in bacteria. The vaccine is efficient and said to last for at least twenty years (Hepatitis B Vaccination, 2012). Vaccines do have some risk for adverse reaction, the most common being redness and soreness at the injection site or fever and allergic reactions. ( 17 ) in 1972, when recombinant DNA was created from the SV40 virus using genetic engineering, much has been discussed . Vaccination is controlled exposure of an animal's immune system to something that causes disease. All rights reserved. The CDC, however, recommends immunization against these diseases for certain individuals that may be at high risk for exposure, such as lab workers or members of the military.
