The fourth story, about the gentle murderer and the real revolution

Hepatitis C is another disease of virus nature, which science is struggling with successfully. But not with the help of vaccination (since there is no vaccine against it now), but with new effective medicinal products.

To begin with, we must say that there are five types of hepatitis: A, B, C, D and E. All of them can cause inflammation of the liver, but they are noticeably different in the way they are spread and the harm they can cause. The most dangerous are B and C. About 96% of all deaths from hepatitis are due to them. Type D is also very dangerous, but its nature is such that it can only accompany hepatitis B, not be by itself.

The fifth story, almost fantastic and scandalous

Over the past decades, HIV has evolved from the plague of the twentieth century into yet another chronic disease – certainly not fatal if treated on time and properly. Unfortunately, there is no “pill” that can completely cure a person from this virus, as in the case of hepatitis C. Although at least one case of a complete cure for HIV is described in science, this is a separate story involving bone marrow transplantation and at this stage, its mass application is out of the question. Millions of people need treatment. According to WHO, almost 38 million people are living with HIV in the world today (as of the end of 2018).

Since the second half of the 1980s, pharmaceutical companies have introduced to the market many medicinal products with different principles of action, which can now slow down and virtually stop the development of HIV infection. A person should take this therapy throughout life, but their life can be as long as that of an HIV-negative person. Or maybe even longer, because such people have to watch their health especially closely. Thanks to modern medicinal products, they can be safe sexual partners and give birth to healthy children.

But there is still no vaccine against this virus. Several different groups of scientists have worked or are working on it, but there is still no officially approved vaccine. For example, the HVTN 702 vaccine was prematurely suspended in South Africa a few months ago. It turned out to be harmless, but it also did not protect against infection.
