This article describes the morbidity of
vaccine preventable infections in the
city of Severodvinsk. The study gives a
detailed description of epidemiological
trends over a long period of time, determines
epidemiological characteristics of
each of the investigated infections and
shows timing charts as well as regularities
in the increase and decrease of incidence
rates. Cyclic trends for every disease
within short-term and long-term periods
have also been defi ned. The information
helps to forecast the development
of epidemiological process, to predict
increases and decreases of morbidity

and to plan organizational and fi nancial
measures. In addition, the epidemic
process of each infection after introduction
of immunization has been studied.
A decline in immunity during the
1900s resulted in an increase in the incidence
of vaccine preventable infections
in the city. For some infections, the incidence
reached the pre-immunization
rate. Lethal outcomes of some infections
(e.g. diphtheria) were registered.
This study indicates that immunization
with coverage rates over 95% is an
eff ective means of decreasing the incidence
of vaccine preventable infections
to a non-signifi cant level.
