Rabies Vaccination
The rabies vaccine is a crucial tool in preventing the deadly viral infection caused by the rabies virus, which affects the central nervous system. Administered both pre-exposure for high-risk individuals and post-exposure following potential rabies contact, the vaccine stimulates the immune system to produce antibodies against the virus. Timely vaccination is essential, as rabies is almost always fatal once clinical symptoms appear. Widely used for humans and animals, the rabies vaccine has significantly reduced the incidence of this once widespread and feared disease.

What is rabies and how is it transmitted?
Rabies is a viral infection that affects the central nervous system and is almost always fatal once symptoms appear. It is transmitted through the bite or scratch of an infected animal, typically dogs, bats, or other mammals. The virus is present in the saliva of the infected animal.
Who should receive the rabies vaccine?
The rabies vaccine is recommended for people at high risk of exposure, such as those traveling to areas where rabies is common, certain laboratory workers, and those who work with animals. Post-exposure prophylaxis (PEP) is also crucial for anyone who has been bitten or scratched by a potentially rabid animal.
What does the rabies vaccination schedule involve?
For pre-exposure prophylaxis, the vaccine is typically given as a series of three doses: on days 0, 7, and 21 or 28. For post-exposure prophylaxis, the vaccination schedule includes a series of four or five doses, depending on the individual's previous vaccination status, administered on days 0, 3, 7, 14, and sometimes 28.
Are there any side effects associated with the rabies vaccine?
Common side effects of the rabies vaccine include mild pain and redness at the injection site, headache, and mild fever. Serious side effects are rare but can include allergic reactions. It's important to report any severe reactions to your healthcare provider.
How effective is the rabies vaccine?
The rabies vaccine is highly effective in preventing rabies when administered according to the recommended schedule. For pre-exposure prophylaxis, it provides protection from the disease, while for post-exposure prophylaxis, it can prevent the onset of rabies if administered promptly after exposure.
How long does immunity last after receiving the rabies vaccine?
Immunity from pre-exposure vaccination typically lasts for several years, but the exact duration can vary. For those at ongoing risk of exposure, booster doses may be recommended. Post-exposure prophylaxis provides immediate protection and is effective as long as the full course is completed.
