The effectiveness of immunization, for example, against tetanus, has not been in doubt since 1914. Then, from August to December, in German hospitals, tetanus developed in 1,700 soldiers, while the mortality rate was 100%. After the serum was supplied to the German army, the lethality was reduced to 1 case per 1000 wounded soldiers. So we have 100% versus 0.1%. That is, tetanus immunization is not a controversial issue.
Without treatment, tetanus is almost always fatal. In those countries where the immunological service is absent or not well developed (countries of Africa, Southeast Asia), the mortality rate from this disease is more than 50%.

No, vaccinations are not harmful.
There are complications and there are vaccine reactions.
Complications are extremely rare, it is about 1 in a million or less. In principle, anything can happen with this frequency.
These are mainly allergic reactions. It has been proven, by the way, that there is no connection between vaccinations and schizophrenia.
Reactions are much more frequent. The response is the response of a healthy body to vaccination. Yes, this is unpleasant, and as the quality of vaccines increases (and as the number of combination vaccines increases) the number of reactions decreases. But in general, this is normal and most often not dangerous.
There are two types of reactions.
Non-specific. It is just a reaction of the immune system to the injected antigen - fever, feeling unwell, local induration, soreness. The better and newer the vaccine, the less nonspecific reactions. These reactions can be stopped by antipyretics and drinking plenty of fluids.
Specific. These are reactions to live vaccines, such as measles or polio. A weakened virus can sometimes cause minor illness. In the case of the measles vaccine, it will be a harmless rash, but with polio, it can be vaccine-associated polio. Therefore, the correct approach is to carry out the first three vaccinations against poliomyelitis with a killed vaccine, and only the fourth (when immunity is formed) - live.
In general, vaccination is safe if the rules are followed. It does not increase the load on immunity - a person is constantly faced with new antigens (especially a child).
Regarding the safety of the unvaccinated in the environment of predominantly vaccinated.
Indeed, in the overwhelming majority of cases unvaccinated patients are safe at the expense of 90% of those vaccinated. They just have no one to get infected. But there are at least two important exceptions (one vaccine).
Tetanus. The pathogen enters through contaminated wounds and dog bites. If the victim is vaccinated according to the calendar (once every 10 years), then he is given only revaccination. If not, immunoglobulin is administered, which is at least 1000 times more dangerous in terms of complications.
Diphtheria. The diphtheria vaccine is antitoxic. Those. it does not interfere with the carriage of diphtheria rods. Anyone vaccinated against diphtheria can be a source of infection, so anyone who is not vaccinated (even if everyone else is vaccinated) can get sick. And diphtheria is a very unpleasant and deadly disease.
Yes, vaccinations are harmful. And not doing them is also harmful. Therefore, it is necessary to choose the lesser of two evils. Evil about vaccinations: there is a risk of complications (the development of the disease, but in a mild form; allergic reactions - redness, rash, Quincke's edema, anaphylactic shock)
Evil from not being vaccinated: the risk of getting sick and getting complications of the disease ( which are more common than with vaccinations), which will result in financial costs, poor health, temporary disability and loss of income, a higher risk of death. The immune layer of the population also decreases, which will further increase the incidence of the population and significantly increase economic and human losses.
Conclusion: with vaccination you risk, but much less than if you refuse it.
It is harmful not to be vaccinated. This is not only harmful to the individual personally, but also socially dangerous. Therefore, many countries have already adopted legislative norms imputing responsibility for refusing vaccination without medical reasons.
On the one hand, no sane doctor will 100% guarantee that vaccination will pass without consequences, because it is all the same medical procedure. Any drug administration can cause side effects. But! The risks of vaccinations are hundreds of times lower than the risks of traveling by bus or car. However, I didn’t notice that the hysterics running from the doctors refused to travel in their car with children.
In fact, vaccinations should be done. They play an especially important role in infancy. Because the symptoms and consequences of the same disease can be very different in childhood and adulthood.
Take whooping cough, for example. Vaccination with DTP (against tetanus, diphtheria and whooping cough) is very necessary, since when an infant is sick with whooping cough, he cannot cough normally, attacks of laryngeal stenosis occur and the child suffocates in a matter of seconds. And an adult just coughs for 2-3 months and that's it, but he certainly won't die.
I won't talk about BCG. Tuberculosis is now very common. And if an adult knows how to protect himself (he constantly washes his hands, is careful in public places), then children do not understand the danger of infection and are more at risk of infection.
Naturally, there are risks of complications, but mainly this is the risk of an allergic reaction, high temperature (40-41 frequent occurrence after vaccination, more precisely the most common, is usually solved by intramuscular injection of analgin).
There is a lot of research on this topic now and there is even more controversy. If we are not talking about such serious ailments as, for example, allergies, then yes, it happens. As for the ongoing controversy over the link between vaccines and autism, the situation is as follows. I don’t know if Asya Kazantseva can be considered a reliable source, but this is what she writes:
"You will not become an autistic after vaccination. This myth was born in 1998 after the publication of Andrew Wakefield's study. He allegedly discovered a connection between measles vaccination and the development of autism in children, backed up by analyzes of twelve meticulously selected babies, shocked British parents, but in 2004, irrefutable evidence was published that Wakefield was wrong and was stripped of his medical title. has become an endemic disease in the United Kingdom again. And Wakefield's ideas are now fevering in Russia. "In any controversial area there is always some One Scientific Article, which is very actively referenced by the general public in the context of" Look, look, the scientist is also with us! " At the same time, if you read the original source, it usually turns out that everything there is far from as smooth as in dozens of retellings on popular sites. "
Here is another and Source:
"In 1999, researcher Brent Taylor and colleagues conducted a carefully controlled study in which they tested the link between measles, mumps and rubella vaccination and the development of autism. They examined data on 498 children with autism and Autism like disorder. Records of children with autism in North Thames County, England, before 1988 (in 1988, measles, mumps and rubella vaccinations were introduced into the routine were selected for the study), and after. Taylor tested the prevalence of autism in each of the groups (among those who were vaccinated after 1988 and among those who were not vaccinated before 1988). He also checked at what age the child was diagnosed with autism. The scientist came to the following conclusions:
- The percentage of vaccinated children was the same among children with autism and among children without this disorder;
- No age differences were found , in which autism was diagnosed in vaccinated and unvaccinated children;
- The time interval from vaccination to the first symptoms of autism was different in each case (two, four or six months).
These findings do not support a biological link between vaccination and morbidity.
Other studies published by researcher Natalie Smith in the Journal of American Medical Association and studies published by researcher Hershel Jick, for the British Medical Journal, showed that more reported cases of autism among children are not associated with more frequent use of measles, mumps and rubella vaccines. "
I wrote all this because I was also interested in this problem. But I have no biological / medical education, so I just shared with you what I found myself. Better, nevertheless, to ask experienced specialists :)
There is a well-founded opinion of the scientific community that at 15% of consciously unvaccinated people, there is a risk of infection even for vaccinated people. After all, vaccination increases the number of antibodies that fight the virus, but does not save 100%. A large number of infected people around - the antibodies cannot cope, and the person gets sick. Another interesting point is that viruses can mutate. The more infected people, the more likely they can mutate, and the vaccine will not cope (unlikely, but is it quite possible?) If you are directly interested in this topic, then I advise you to watch the video about vaccination. Quite accessible explanations, after which there should be no questions and very striking examples.
