The mumps component comes from the Jeryl Lynn strain, isolated in 1964, and the rubella component is derived from the RA 27/3 strain, isolated in 1964 as well. These strains have been extensively studied and modified to ensure their safety and efficacy in the vaccine.
In addition to the viral components, the MMR vaccine also contains other ingredients that help to stabilize and preserve the vaccine. These include sorbitol, a sugar alcohol that acts as a stabilizer; gelatin, which helps to keep the vaccine from freezing; and Thimerosal, a preservative that prevents the growth of bacteria and fungi. The vaccine also contains trace amounts of antibiotics, such as neomycin and streptomycin, which are used during the manufacturing process to prevent bacterial contamination.
The MMR vaccine is administered via injection, typically in two doses, with the first dose given at 12-15 months of age and the second dose at 4-6 years of age. The vaccine is highly effective, with studies showing that it provides long-lasting immunity against measles, mumps, and rubella.
In conclusion, the MMR vaccine fits the biologic definition as it contains live, attenuated viruses that stimulate the body's immune response to protect against infectious diseases. Its composition, including the weakened viral strains and stabilizing ingredients, has been carefully developed and tested to ensure its safety and efficacy.
