The whole truth about vaccinations: whether to do and how they can harm

The autumn season came, and with it the snot and cough season. In addition to a relatively harmless cold, in the dank season of the year, the risk of contracting various infections increases, the most common of which is the flu. "Popular mechanics" understands whether vaccinations should be given, what they are fraught with, and whether there is any sense in them.

The introduction of a weakened or killed form of the pathogen to a healthy person in order to induce his body's immunity to the disease is called vaccination. There are also vaccinations based on individual proteins of the virus or bacteria, which are the target for the immune system. Medicine was able to create vaccines against most of the most common infections, which is one of the pillars of such high quality and long life of a modern person compared to our ancestors.

Immunization, even against seemingly unlikely infections, is extremely important both for the health of an individual and for the well-being of the whole society. Often, flu, rubella, chickenpox, and other "ordinary" diseases are easy, but even before their manifestation (symptoms of symptoms), the infected spreads pathogens around him. Thus, it can easily cause someone else's sick leave or, in extreme cases, death. It is especially dangerous when a person continues to go to work or study, putting his colleagues and everyone who is close to him in transport at risk.

It is impossible to consider all relevant for at least only Russians infections within the framework of one article. The main thing to remember is that each region may have its own list of recommended vaccinations, which it is advisable not only to familiarize yourself with, but also to complete it.

Myths and real dangers of vaccinations

There are a huge number of biases associated with immunization, but none of them finds experimental evidence. They are caused by the general ignorance of ordinary citizens about the contents of the vaccines, their mechanism of action, as well as disinformation. So, according to the results of a large-scale study of more than 650 thousand children vaccinated against measles, mumps and rubella, no pattern was found between vaccination and the onset of autism. The only correlation between it and vaccinations is in the timing of the latter and the age of manifestation of autism. Moreover, the only study supporting this myth turned out to be fraudulent.

There are no systemic poisons in modern vaccines, and the ethyl mercury contained as a preservative leads to the ingestion of no more than 6 micrograms of this metal. This dose is not only safe even for an infant, it is less than a person receives with food weekly. Most vaccines are designed so that their use even by people with weakened immune systems does not cause serious complications, but risk factors cannot be completely avoided. The most dangerous side effects can cause the BCG TB vaccine - one case of generalized infection per 230-640 thousand doses. This is slightly higher than the likelihood of contracting tuberculosis, but its course and damage to health as a result are incomparably lower.

The most likely consequences of vaccinations, in addition to the expected protective effect: mild malaise, allergic reactions specific for a particular vaccine manifestations, as well as the lack of an immune response. Of all the above concerns, only allergies and drug malfunctions can cause. In any case, before immunization, you must consult your doctor, make a schedule of vaccinations and be sure to be healthy. Most often, complications arise due to the fact that the vaccination was carried out without observing the mandatory instructions for it.
