RESUMO
In the introduction achievements of obligatory applied vaccines are described. Data on new vaccines for wide application are presented: acellular pertussis vaccine, Haemophilus influenzae b vaccine, hepatitis B vaccine and varicella (zoster) vaccine. For each vaccine data on immunity, protection and side effects are presented. Indications (epidemiological, illness severity) justifying vaccination as a method of protection from infection with a distinctive causative agent are presented. Antigen structure is given for each vaccine. Finally the form of application and age of primovaccination and revaccination are given. The conclusion is that these vaccines give high immunity and protection like those already in wide (obligatory) usage, and have less side effects.

In a study of the prevalence of hepatitis A virus antibody in urban Yugoslav children aged 0-7 years, 18.2% were positive; most of them were only a few months old. The maternal origin of antibody in these very young children could be inferred from the rapid decrease of antibody during the first 5-7 months of life, following which period until the age of 7 years, there was no significant increase in the proportion with antibody. It was concluded that the age range included in this study (0-7 years) does not represent a time of life when most urban Yugoslav children come into contact with hepatitis A virus.
