Vaccines are designed to protect against infection by no more than 15 types of viruses and bacteria, but there are hundreds of them! Some vaccines have been proven to be effective (smallpox, measles, polio, mumps, hepatitis A, rubella, chickenpox, whooping cough, diphtheria, tetanus, rabies). Recovered or vaccinated against these diseases, they no longer become infected with them all their life or for many years! The effectiveness of other vaccines is questionable. Attention! Vaccination in a short time of many million population of countries is practically impossible! The effectiveness and safety of revaccinations in a short time has not been proven! Attempts to create a vaccine against such dangerous, common diseases as hepatitis C, HIV, Epstein-Barr virus have so far been unsuccessful! The situation with medicines for protozoa, worms, fungi is the same. Treating stress fears with drugs is also difficult and not safe. This is why there are so many chronic and incurable diseases. All over the world there is a growing number of people who do not trust doctors, analyzes, medicines!
