Vaccinations against bacterial infections.

The achieved or achievable standard of vaccination measures against bacterial infections is discussed with reference to 3 groups of vaccines. The first group involves well established and commonly used vaccines such as BCG and DPT vaccines. The second group includes newer vaccines or vaccines that are under development, for instance vaccines against meningococci, pneumococci, H. influenzae and enteropathogenic E. coli. The third group covers vaccines whose realisation at present appears to be difficult or hardly feasible, for instance vaccines against enterotoxins of enteropathogenic organisms, against lues, gonorrhea or, example, against organisms of hospital infections.
