Rabies Post-exposure Prophylaxis

What is Rabies Post-exposure Prophylaxis (PEP)?

Rabies Post-exposure Prophylaxis (PEP) is a series of four to five doses of rabies vaccine that can be given to people after they are exposed to a possible rabies infection. The purpose of PEP is to prevent the onset of full-blown rabies in a person who may have been infected. PEP is administered if the person has been bitten, scratched, or licked by an animal that is suspected or confirmed to have rabies.

How is the PEP administered?

PEP is administered in the form of four to five doses of rabies vaccine. The vaccine works by stimulating the body's immune system to produce antibodies against the rabies virus. The doses are injected into the upper arm in two different sites, usually on days 0, 3, 7, 14, and 28. The first dose of the vaccine must be given as soon as possible after exposure to the potential source of infection, ideally within 24 hours.

How effective is PEP?

PEP is highly effective at preventing the onset of full-blown rabies in people who have been exposed to the virus. In the overwhelming majority of cases, people who have received PEP will not develop rabies. However, there is still a small risk of infection, and it is important that people receiving PEP receive all of the recommended doses.

What are the side effects of PEP?

The most common side effects of PEP are mild and include pain, redness, swelling, and itching at the injection site. Other possible side effects include headache, fever, nausea, exhaustion, muscle aches, and hives. Most of these side effects are mild and tend to clear up within a few days.

What should I do if I have been exposed to an animal that may have rabies?

If you have been exposed to an animal that may have rabies, it is important to seek medical attention as soon as possible. Your doctor will assess the risk of rabies and, if necessary, prescribe a course of PEP. It is important that any course of PEP is completed in full to ensure the best possible protection.

Conclusion:

Rabies Post-exposure Prophylaxis (PEP) is an effective way to prevent the onset of full-blown rabies in people who have been exposed to the virus. The PEP consists of four to five doses of rabies vaccine that are injected into the upper arm at two different sites on days 0, 3, 7, 14, and 28. PEP is generally well tolerated, and most side effects are mild and short-lasting. If you believe that you have been exposed to an animal that may have rabies, it is important to seek medical attention as soon as possible in order to receive the necessary PEP.
