Which of the following diseases still have no known vaccine

[DreamWeaver]

I'm looking for some help understanding which of the following diseases still have no known vaccine. Does anyone have any knowledge about this that they could share? I know that some diseases have vaccines, but I'm wondering which of them don't. Has anyone had any experience with this, or do you know anyone who has? Any advice or information would be greatly appreciated.

Hepatitis C

Hepatitis C is a viral infection that can cause serious health problems and even death. Unfortunately, there is still no known vaccine for the hepatitis C virus. Treatment options are available, but they are not always successful and may have side effects. Some research suggests that a vaccine for hepatitis C may be available in the near future, but it is still in the early stages of development.
