Dose ScheduleTop

Pre-exposure rabies vaccines are administered by a series of three injections:

• The first dose may be given at any time
• The second dose should be given seven days later
• The third dose should be given 21 or 28 days after the first dose
• Booster doses of vaccine are recommended every two years for those individuals who continue to be at increased risk of contracting rabies to maintain protective antibody levels. People that work with live rabies virus in laboratory settings should be tested every six months to ensure that they have adequate antibody levels, and receive boosters as necessary.
