hy is the Sterne vaccine from the 1920s still widely used today
With the continuous advancement of modern medicine, the importance of vaccines in public health has become increasingly prominent, and the Sterne vaccine is one example worthy of attention. The vaccine dates back to the 1920s and was developed by Austrian-South African immunologist Max Sterne. It uses live attenuated strains to fight anthrax and is still widely used around the world.
"Sterne vaccines have become the standard choice for poultry and livestock vaccines due to their excellent effectiveness and relative safety."
The success of this vaccine is due to several key factors. First, the production process of the Sterne vaccine is based on technology pioneered by Louis Pasteur in the 19th century, which not only makes the vaccine effective but also reduces the risks in the production process. In his research, Max Sterne is committed to precisely adjusting the pathogenicity and immunogenicity of vaccines in order to prevent casualties during the vaccination process in advance. Ultimately, he succeeded in creating a strain called 34F2 that is now the basis for the anthrax vaccine for livestock made in nearly every country.
Although the Sterne vaccine achieved remarkable results given the technology available at the time, its popularity was not only due to the efforts of the researchers. The wide availability and relative ease of administering the vaccine is also an important factor. Soon after the vaccine came out, countries quickly started its production and successfully promoted it in agriculture, effectively reducing the incidence of anthrax in livestock.
"Under the influence of vaccines, livestock productivity in many countries has increased significantly, which has also had a profound impact on the development of the agricultural economy."
However, some technical limitations of the Sterne vaccine must be taken into account when promoting its use. Because it is a live vaccine, doctors will recommend avoiding vaccination while taking antibiotics to ensure the immune effectiveness of the vaccine. At the same time, it is also important to note that the vaccinated animals cannot be slaughtered for a certain period of time.
Global use of vaccines
The Sterne vaccine is not only used in South Africa, the country where it was developed, but many countries have included it in their official vaccination programs. In these countries, farmers and veterinarians generally affirm the preventive and therapeutic effects of the vaccine, leading to the rapid growth of the breeding industry.
It is worth noting that the countries that produce Sterne vaccines today still use the basic technology of the 34F2 strain and improve it with various methods to produce more efficient and safe vaccines. At the same time, research on the next generation of vaccines is still ongoing, including recombinant vaccines and subunit vaccines.
Current Challenges and Future Directions
Although Sterne vaccines have achieved many successes in the past few decades, as people's understanding of vaccine safety and effectiveness increases, some new vaccines are still in the research and development stage and still require a lot of verification and testing. In the future, the scientific community may conduct more detailed research on the vaccine manufacturing process and long-term effects to promote the development of more advanced vaccine technology.
"Vaccine research will continue to be an important topic in future epidemiological studies, especially in the context of accelerated globalization."
In general, the continued use of the Sterne vaccine is an important milestone in medical history. It not only marks the success in the fight against anthrax, but also provides valuable experience for future vaccine research and development. As science and technology advance, we can't help but wonder: How will vaccines continue to evolve to protect our health and safety in the face of emerging infectious diseases?
