An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). ( 17 ) in 1972, when recombinant DNA was created from the SV40 virus using genetic engineering, much has been discussed . Centers for Disease Control and Prevention. Children have also been known to have serious allergic reactions to a vaccine. There are approximately three hundred and fifty million carriers of hepatitis B in the world, an estimated amount of seventy five million to one hundred million of those infected with the virus dying from liver cirrhosis or liver cancer as a result. Children in whom the vaccine is 100% effective protect those few who have not been completely immunized -- lessening everyone's chance of exposure to the disease. How to cut DNA: There are special tools that can be used to cut DNA called restriction enzymes, also known as DNA scissors, in order to combine DNA with different living things.

Another concern about vaccines involves the use of a mercury-based preservative called thimerosal. In fact the age groups with the highest rates of hospitalizations from the flu include those 0 to 4 years of age and those older than 65. Hepatitis B is a major health concern that has plagued the world since the dawn of time. However, all three vaccine types: egg-based IIV, ccIIV, and RIV still elicited immune responses against the flu virus strains these vaccines were designed to protect against. What are the possible benefits of recombinant flu vaccines? Thimerosal has been used as a preserving agent in some vaccines and other products since the 1930s. Most of the recommended childhood immunizations are 90%-100% effective, according to the CDC. Live attenuated vaccines are the closest things to getting the real deal of an infection. Such studies will also need to assess vaccine benefits against laboratory-confirmed outcomes to minimize bias and ensure accuracy of the findings.
