Rabies Vaccines 2023
Rabies Vaccines 2023
Rabies is a vaccine-preventable viral disease in more than 150 countries and territories, say the World Health Organization (WHO). Rabies vaccination can prevent infections before and after exposure to the rabies virus. Unfortunately, almost 60,000 people worldwide die from rabies each year.
Unlike the conventional, inactivated rabies vaccine, live-attenuated viruses are genetically modified viruses that can replicate in a vaccinated person without causing adverse effects while eliciting robust and effective immune responses against the viral infection.
The U.S. Centers for Disease Control and Prevention (CDC) updated its recommendations for rabies preexposure prophylaxis for humans, replacing the three-dose vaccination schedule with a two-dose program, intending to protect for about least three years.

Importation of Dogs
After October 2021, dogs from high-risk countries entering the U.S. with CDC Dog Import Permits must enter only at approved ports of entry. As of November 2021, High-Risk Countries for Dog-Rabies is posted at this CDC link. In the Americas, rabies is commonly caused by a bat bite.
