As the worldwide spread of Corona 19 is showing no sign of ending, other infectious diseases such as the Black Death (Fest) in neighboring countries such as China have been focused on developing vaccines.

Why are there no vaccines for these infectious diseases? According to the medical community, there are many cases of new infectious diseases that occur first in developing countries due to hygiene and wildlife eating habits, so drug development tends not to be a preemptive measure.

Professor Kim Woo-joo of the Department of Infectious Diseases at Koro Hospital in Daegu called it'Inequality of Infectious Diseases'.

According to Professor Kim, new infectious diseases mainly occur in developing countries such as Africa and South America, and there are not many confirmed cases in developed countries.

As such, there is no economic incentive for large multinational pharmaceutical companies to develop vaccines to supply patients in developing countries with low purchasing power.

In addition to Corona19, most of the new infectious diseases such as Zika virus, Ebola, SARS, and MERS do not have a clear vaccine to date.

In severe cases, methods such as ventilator and dialysis are used, and extensive antibacterial agents are used to prevent pneumonia due to secondary infection, but this is not a fundamental solution.

Even infectious diseases that have persistently plagued humanity do not develop preventive therapies if there is a lack of vaccine demand.

In 1999, the development of vaccines was stopped in Fest, where a number of deaths occurred in medieval Europe, with more than 2,500 cases still occurring annually.

This is because there is not a large number of confirmed cases per year, and treatment with antibiotics is insufficient.

In fact, lung and sepsis fests have a very high fatality rate of 30 to 100%, but when properly treated with antibiotics, they decrease to 15% or less and 30-50%, respectively.

However, new infectious diseases are no longer just a problem in developing countries.

According to a report by the Korea Institute of Science and Technology Planning and Evaluation (KISTEP),'A New Infectious Disease Crisis Response Report', the global pandemic is spreading worldwide as new epidemic diseases spread across the world due to increased population mobility, climate change, and aging. The possibility of leading to (Pandamic) has increased.

Professor Woo-Joo Kim emphasized, “With the development of means of transportation, it is necessary for global cooperation for infectious diseases with few cases to be confirmed because infectious diseases can spread to any region regardless of the origin.”

"Rather than relying on private pharmaceutical companies to supply on demand, governments in developed and developing countries should work together to develop vaccines and treatments," he said.
