The Global Organization for Animal Health (WOAH) is urging for caution as modified live vaccines for African swine fever become increasingly available. The organization stresses the importance of a well-tested and accurate vaccine, warning that an ineffective vaccine could worsen the spread of the disease.
African swine fever has posed a significant challenge for years, with no vaccine or effective treatment available. Now, as modified live vaccines are being developed and brought to the market, many countries have shown interest. However, the WOAH warns that relying solely on vaccination and neglecting other biosecurity measures, such as minimizing transport movements, could lead to further spread of the disease.
In addition to the risk of spreading the disease, the WOAH also highlights the potential dangers of inadequately tested vaccines, which could lead to chronic diseases in pigs. The organization stresses the need for a well-designed vaccination program that considers local epidemiology, vaccination objectives, and the availability of technical, financial, and human resources.
The WOAH emphasizes that any vaccination program should include post-vaccination surveillance and monitoring, as well as an exit strategy for discontinuing vaccination. These measures are outlined in the WOAH International Standards on Vaccination, specifically in Chapter 4.18 of the Terrestrial Code.
As countries consider implementing vaccination programs for African swine fever, the WOAH’s guidance serves as a reminder of the importance of careful planning and testing to ensure the effectiveness and safety of vaccines in combating the disease.]
