[Biotechnology and vaccinations].
Current biotechnologies used in the manufacture of new vaccines are of three kinds: Genetic recombinations leading to either vaccinal sub-units or living vaccines represented by recombinant vectors; Chemical synthesis techniques; Use of the spatial configuration of an anti-antibody similar to the initial antigen. These are the anti-idiotype vaccines. Genetic engineering is the basis of a new generation of vaccines, sought with the aim of attempting to eradicate a number of diseases throughout the world. However, there is presently an inadequacy in resources, most often linked to financial considerations, which limits widespread systematic vaccination. In the future, vaccines against dental caries will probably be obtained from purified proteins of hydrolase fractions common to cariogenic bacteria and resulting from genetic recombinations in the form of vaccinal sub-units.
