For the first time, Louis Pasteur began to fight deadly diseases by vaccination, it was he who invented the vaccine against rabies, which is almost 100% fatal in case of clinical symptoms, but now there are vaccines for many dangerous infectious diseases
But there are 2 types of cancer that viruses cause - this is cervical cancer caused by the human papillomavirus and liver cancer caused by the hepatitis B virus. And there are vaccines that can prevent infection with these viruses and, as a consequence, prevent the development of these two types of cancer.
If the question of vaccination, then hepatitis B is an incurable disease, and yes, you can get immunity from it through vaccination.
AIDS there is no vaccine, but it is now being treated well.
There are no vaccines for cancer other than that caused by the human papillomavirus, but cancers are very diverse and bypass new methods of chemotherapy.
Diabetes can be treated well. It is important to separate type 1 and type 2 diabetes. First, this is an autoimmune disease, like all other autoimmune diseases, its origin is unknown, more precisely, it occurs against a background of severe stress. Type 2 is a metabolic disorder due to an improper sedentary lifestyle and, at the root, an incorrect diet. Accordingly, type 2 can be prevented by adhering to a diet and diet, maintaining a healthy weight and mobility. But both the 1st and the 2nd type are treated. There are insulin pumps that help young people keep an active lifestyle in type 1.
In fact, as a doctor, I came to the conclusion that it is quite possible to avoid incurable diseases. But medicine can only partially help in this. It is very important to engage in prevention - nutrition, exercise, tempering, do not smoke, do not drink, drink enough water per day, do not let the weight go beyond the normal range. And the most important thing is sleep. And stress resistance! That is, stress underlies almost all diseases, primarily incurable.
You need to learn how to set priorities in your life - first, healthy sleep, and, as a result, health, then reliable healthy relationships in the family and with oneself yourself. And then just work and the rest. This has been repeatedly proven by various studies conducted by clinical psychologists. A healthy internal psycho-emotional state directly affects life expectancy and the development of various diseases.
Timely vaccination, of course, also helps to avoid early infant mortality and morbidity.
There is an innate (genetic) immunity to diseases that we, at this stage in history, consider incurable. So yes, really.
Really, get immunity, but not from all diseases. Not all diseases that were previously fatal are also now fatal, they can now be cured, including drug treatment. Diseases caused by various pathogens are amenable to immunization, usually vaccination. Vaccination triggers the body's immune response, antibodies can be produced by the body on average, a certain time. On some pathogens, immunity lasts all life, and some vaccines "work" for a certain time. Basically, vaccines are vaccinated against diseases that can cause death, the list can be found on the Internet (it is quite extensive). Some diseases that can be fatal do not have the ability to prevent them, and the causes of many more fatal diseases have not yet been determined by science, they cannot be immunized, remaining fatal to humans.
