Japanese Encephalitis (JE) is a highly contagious viral disease that can be deadly in children and adults. It can cause severe neurologic complications, including death. There is currently no cure for JE, so it is important for people who are likely to be exposed to the virus to receive the vaccine. So, people must get vaccinated as soon as possible. The Japanese Encephalitis vaccination for travelling is available, and although it provides some protection against the disease, it does not last for a lifetime.
Vaccine Efficacy and Prevention
Approximately 80% of people who receive the vaccine develop immunity to JE within two years, but this level of protection declines over time. But you may be wondering how long does the JE vaccine last? Most people have a few different questions in their heads about this vaccine. Two doses of the JE vaccine can boost the seroconversion rate to 60% at ten days post-vaccination.
While there are currently no proven efficacy or effectiveness data on JEV vaccines, there have been numerous studies demonstrating the value of this vaccine. Despite the challenges, there are some promising results. A special Japanese Ministry of Health and Welfare team evaluated the efficacy of a second-generation JE vaccine.
Protection For At Least 10 Years
A new WHO/UNICEF report updated global estimates of the disease burden and vaccination effect following the introduction of a vaccination campaign for JE in Nepal. The study estimated that the number of JE cases is now at least 100,000 per year, which is reasonable.
The World Health Organization estimates that the JE vaccine is almost 100 percent effective. The vaccine effectively protects humans from the disease after vaccination, but more research is needed to refine the estimate. Japanese Encephalitis vaccination for travelling is a series of three shots over about 12 weeks. There is no particular period for how long the antibody endures, but studies suggest that it may protect for up to 10 years. In the meantime, the vaccine is still a valuable public health measure to keep rates high and vaccination coverage high. Further studies using serological data will further refine the estimate of the vaccination’s effectiveness.
Need For Booster Doses
If you have not yet received the Japanese encephalitis vaccine, you should wait at least one week before travelling to a country where an ongoing epidemic is. The safety of the Japanese encephalitis vaccine has not been evaluated, so it is important to complete your primary immunization series before the booster doses. There is also a small risk that this vaccine may interact with other drugs, including other vaccines and medicines used to treat organ rejection.
Final Thoughts
Before travelling to any country in Asia where an ongoing epidemic exists, you should wait to undergo the Japanese Encephalitis vaccination for travelling. The vaccine will help reduce your risk of contracting the virus. If you are already in a country with an ongoing epidemic, you should take precautions to avoid mosquito bites. The vaccine is available at most clinics and hospitals, so there is no reason to delay vaccinating. Remember, the best way to protect yourself from Japanese Encephalitis, a deadly disease, is to be vaccinated.
