[Vaccination as a means of prevention].

While recognizing the fact that the use of strict hygienic techniques, disposable materials and quality control are essential for sterilizing instruments, vaccination still remains the most efficient way to combat infection. In this article, the authors discuss the principle problems associated with the use of vaccines and especially as they relate to the dental office. Hepatitis B is certainly of interest to all dentists and their personnel, especially since its primary mode of transmission is by contact of blood with the skin and the mucosa. The two forms of vaccines presently available, are derived from the human plasma of carriers or from yeast and cause a genetic reaction which produces hepatitis B virus antigens. These vaccines protect at least over 90% of all healthy individuals and do not generate any secondary infection or unfavorable reactions. Faced with the reality of hepatitis B, it is very wise to remember that it is BETTER TO BE VACCINATED THAN TO HAVE TO LIVE WITH THE EFFECTS OF HEPATITIS.
