Recommended Vaccines: Routine boosters and adult vaccinations, not overlooking tetanus and diphtheria, and polio. Typhoid and hepatitis A and B vaccines are recommended as well.
Malaria: Little to no risk; try to avoid insect bites.
Other Issues: As in Russia and other parts of Eastern Europe, tick-borne encephalitis (and other tick-borne diseases) and avian influenza can be hazards. Take precautions against insect bites and stay away from wild birds as well as large groups of birds at places such as poultry farms or markets. Cholera crops up occasionally although rarely infects travelers from developed countries. Check the current situation where you are going and ask your doctor if she would advise a vaccine.
