"Sovigripp" (vaccine): reviews of doctors and patients. Description, instruction, contraindications
Well, today we will try to figure out which "Sovigripp" (vaccine) reviews earn from doctors and patients. This drug is extremely important for modern man. After all, it is he who helps fight against viral infections, the epidemics of which are so common. However, before you inject, you really need to know what doctors and patients think about this. Maybe it's better to use old vaccines in general? Or do you pay attention to the new one? Let's deal with this issue.
Description
Let's start with the fact that "Sovigripp" (vaccine) reviews are received from the time of its description. That is, once patients know what it is, they write their opinions about the drug. This is not entirely correct. But the fact remains.
The thing is that "Sovigripp" is a kind of new Russian flu vaccine. A certain concentrated solution in ampoules, which contains killed and weakened influenza bacteria of various types. Honestly, there is nothing special about this. Only now "Sovigripp" (vaccine) reviews of consumers are not the best character for the fact that it is domestic. The modern population is skeptical of Russian vaccines. Especially to the new. Just this is our current drug.
Indications
Of course, you can not do without special indications. And this vaccine against the flu "Sovigripp reviews about which will be presented to our attention with you later, has a number of both recommendations and contraindications. They need to pay close attention. After all, injections of the virus and vaccinations are not jokes.
"Sovigripp" is a vaccine that is recommended for administration to the entire adult population, who wants to increase their immunity and protect themselves against influenza of various types. Allowed use by people aged 18 years. As the manufacturers assure, even during pregnancy and lactation (the most vulnerable categories of citizens, by the way) can be vaccinated with the drug. Extremely recommended "Sovigripp" (vaccine), reviews about which are left ambiguous, those with whom reduced immunity, and there is a risk of serious complications after disease. Sometimes this tool is also used for routine vaccination against influenza in schools. But it extends exclusively to the senior link of schoolchildren (grades 8-11).
Contraindications
Contraindications should not be forgotten. It is not enough to want to protect yourself from viral diseases and flu. It is also necessary to have an idea of when it is impossible to carry out injections. Otherwise, you can simply damage your own health. "Sovigripp" (vaccine), instructions, reviews and the effectiveness of the application are presented to our attention, it is not just some kind of injection. A really serious injection. And for this reason, one should not overlook contraindications.
Vaccine against the flu "Sovigripp reviews which are of interest to many patients are not recommended for to people with hyper-sensitivity, and also to those who generally have an intolerance to any vaccines. Such cases are rare, but they have a place to be. Also, with virus diseases, elevated temperature and any malaise, a prohibition is imposed on Sovigripp. Young children and schoolchildren of junior level of training, too, can not inject this injection. If you are prone to allergic reactions (including protein), you can also forget about the domestic method of protection from ARVI and influenza.
This does not end there. Strong postvaccine reactions of the body and chronic diseases in the patient are also the reason for refusing to vaccinate with the drug. Thus, we can conclude that the contraindications for the drug is more than enough. It is not necessary to be frightened - such restrictions are superimposed on the majority of vaccines. After all, a person should get a weakened or killed virus when the body is in perfect condition. Otherwise, there is a risk of not developing immunity, but a disease.
Opinion of doctors
An important point is also what doctors think about the domestic vaccine. It is not for nothing that before any vaccination it is advisable to consult a specialist. Vaccine "Sovigripp" reviews doctors earn, oddly enough, very good.
Many argue that this tool of Russian production helps to fight the flu and its viruses faster than others. In addition, doctors argue that the risk of complications in this case is reduced to almost zero. Ostensibly almost all patients calmly and without consequences transfer the injection.
Plus, sometimes this drug is prescribed for children. So, there is every reason to trust the vaccine. A pediatrician will never prescribe a drug that can harm a child. Yes, doctors also emphasize that for maximum effect it is necessary to inject "Sovigrippom" annually. But this is a compulsory measure, and it applies to all vaccinations against influenza. So there's nothing to be afraid of.
Patients say
But the opinion of patients does not always coincide with the words of doctors. So the population is arranged, that there is no special trust for Russian medicine in the last time. And so "Sovigripp" (vaccine) reviews patients earns are not the best.
For example, the main reason for this is the manufacturer. He is Russian. And this fact already makes people doubt the effectiveness and safety of vaccination. It's not a secret for anyone that in Russia, despite the country's development, testing of medical products is not very effective. And so the risk of complications after injections remains high. But all this is carefully hidden. After all, the main task for physicians is to promote national medicine.
In addition, patients do repeatedly emphasize that after the vaccine they have a dramatic deterioration in their general health for several days. All this is written off to the side effect of the drug. Only now there are these cases very often. And this does not please the population. Sometimes after vaccination, you can feel really ill. This is exactly what the people who already tested "Sovigripp" say.
Outcomes
Which of these can be inferred? "Sovigripp" (vaccine) reviews get questionable and ambiguous. Opinions of doctors and patients were divided. And here everyone has the right to decide who to believe more. In principle, if you do not suffer from viral diseases, and also are not afraid of new drugs, then our current version is quite suitable for injections.
"Sovigripp" (vaccine), instructions, testimonials, recommendations and contra-indications of which were presented to our attention, is a domestic product first of all. Do not be afraid of him. Yes, to experiment in the event that you suffer from side effects, it is not necessary. And children do not need to inject such injections, until this drug is considered a "new word" in medicine. Otherwise, there are no apparent reasons for fear.

The population faces epidemics of influenza annually. In comparison with the symptoms of other common acute respiratory infections, the symptoms of ailment are among the most severe. Recently, many are interested in methods that will help to protect themselves and prevent the development of the disease. Among the available options grafting is not the last place. Experts argue that the vaccine "Ultriks" is able to significantly increase the body's resistance to attacks of pathogenic pathogens.
General description of the vaccine
"Ultriks" is an inactivated solution, which contains influenza viruses of several strains cultivated on chicken proteins: A / H1N1, A / H3N2 and B. One dose contains 15 μg hemagglutinin of each type of virus. According to the official instruction, as an auxiliary agent sometimes used Mertiolate (preservative). The composition of the vaccine varies every year and contains mutated viruses in several previous years, which helps to protect the body from an "unfamiliar" infection.
Large-scale clinical trials have proven the effectiveness of the drug. A feature of the vaccine is the presence of pseudovirus particles in the composition, which stimulate the production of immunity at the cellular level. This provides longer protection against the influenza pathogen. The vaccine against the flu "Ultrrix" (the manufacturer - "Microgen Russia) is produced in syringes and ampoules, which contain a colorless liquid (, ml).
Who is vaccinated?
According to the manufacturer's recommendations, the vaccination is indicated for persons at risk:
- Children (starting from 6 years old).
- People who are often ill with acute respiratory diseases.
- Employees of medical institutions, kindergartens, schools, universities.
- Patients with diseases of the endocrine system, the heart.
- Persons older than 60 years.
- Patients with somatic pathologies.
Influenza is a particularly contagious viral disease, and infection occurs even with prolonged contact with the patient. Every year a huge number of people suffer from this ailment and various complications: pneumonia, meningitis, otitis, encephalitis.
Vaccination is the most effective way of preventing infection with the virus. The procedure advises doctors to spend every year, but at the same time the vaccination is not mandatory and is done purely at will.
Disadvantages of the procedure
Vaccines against influenza have been created for more than half a century, and the composition of drugs is improving every year. Despite this, the vaccine does not give full protection from the virus. A person even after it can get sick, and in some cases the ailment proceeds in severe form. Ultrriks anti-influenza vaccine is effective only for 12 months. According to experts, it provides good body protection, but after a while, vaccination should be repeated.
Many patients are concerned about the presence of preservatives in the vaccine. This fact often becomes the main reason for refusal of vaccination, especially if it is a child. To avoid the negative consequences of the introduction of the vaccine, you must first get a consultation from your doctor, find out the contraindications to the procedure.
"Ultrix" (vaccine): instructions
The manufacturer recommends that you vaccinate annually to protect yourself from the severe course of the influenza virus and further complications. The procedure should be carried out in the autumn-winter period. Also, grafting will be effective at the beginning of the aggravation of the epidemiological situation.
If the integrity or marking is violated, the syringe is considered to be defective and can not be used to administer the drug. Also, special attention should be paid to the liquid for injection. Normally, it should be transparent, and the appearance of sediment, the colors indicate the non-observance of storage conditions and shelf life. Before the manipulation it is necessary to shake the contents of the syringe and remove the air, slowly pressing the piston.
The procedure is carried out under strict antiseptic conditions. The ampoule with the vaccine before opening is wiped with a cotton swab dipped in ethyl alcohol (70%). After opening the ampoule, the solution is taken into a new syringe and the remaining air is removed. The place of administration of the vaccine (the upper third of the outer surface of the shoulder) is treated with an antiseptic, after which the injection itself is done.
Vaccination of children with Ultrix vaccine
The need to vaccinate children against influenza is in question not only in most parents, but also in some specialists. Inactivated Ultrix vaccine is used in pediatrics, but only for children over 6 years of age. Preliminary it is necessary to pass inspection and to exclude all contraindications for carrying out of manipulation.
Do a child vaccinate against the flu virus, should be decided only by the parents. If the child does not attend educational institutions (kindergarten, general education or sports school), then perhaps, the manipulation should be postponed for the next year. Recommended procedure for children who go to school and are prone to frequent colds.
Contraindications
The vaccine can be administered only if the patient is healthy, he does not have signs of acute respiratory infections, colds, flu. Before manipulation, the body temperature should be measured, and if the indicator is above 37 ° C, grafting is prohibited.

The patient may have an individual intolerance to the chicken protein or other components of the agent. Postpone for a while, vaccination against influenza should be accompanied by exacerbation of chronic diseases. Inoculation during breastfeeding is unacceptable.
Do I need a flu vaccination?
Even the immunologists and virologists themselves do not have a single opinion on the need for vaccination against the flu. On the one hand, the procedure allows at least a short time to protect the body from a serious illness, on the other - there is a risk of side effects.
The advantage of grafting is a significant reduction in the number of cases of infection. If the infection with the virus still happened, the vaccine against the flu "Ultrix" will help to transfer the disease much easier. In some situations, the disease can even flow in a latent form. Vaccination showed good results - the death rate from influenza and its complications decreased significantly.
Could there be complications?
Withdrawal from vaccination in most cases lies fear of the development of side effects and deterioration of health. The manufacturer of the vaccine "Ultrix" warns that such a situation is possible. After vaccination, allergic response of the immune system to the components of the drug may occur. Most often there is redness and swelling at the injection site. Within a day after the procedure, the local reaction must pass.
Some patients experienced side effects in the form of symptoms of infection with the influenza virus the next day after the manipulation. Parents should be aware that when the body temperature rises in the baby, the appearance of weakness after vaccination should seek medical help (ambulance or ambulance).
"UltriX" in pregnancy
According to the instruction, no research has been carried out regarding the effect of the components of the vaccine on the course of pregnancy and development of the fetus. Doctors are recommended to be vaccinated during pregnancy planning. In the first 12 weeks, the vital organs are laid in the baby, so administering the vaccine is extremely dangerous and undesirable. There are situations, for example a high risk of infection, when the introduction of influenza vaccine is possible from the second trimester. In this case, it is allowed to use exclusively inactivated vaccine.
At the same time, experts say that the risk of developing any deviations in the fetus even after vaccination on the initial term of pregnancy is almost zero, but influenza infection can lead to severe deformities and anomalies. In any case, the need for vaccination should be determined by the attending physician.
What is the difference between the vaccines "Ultriks" and "Grippol"?
Currently, there is a wide choice of means for vaccination against influenza, both domestic and imported. The UltriX vaccine contains both internal and surface antigens of influenza A and B viruses, which makes it one of the most effective. No less effective is the vaccine "Grippol which is produced in Russia and Uzbekistan. The composition for injection is somewhat different and in addition to strains of the influenza virus contains polyoxidonium. The substance has a powerful detoxification and immunomodulatory effect.
What will be better vaccine - "UltriX" or "Grippol" - should be decided by the attending physician. It should be borne in mind that "Grippol" can be used to vaccinate babies from 6 months already. Also, clinical studies have shown that the drug is absolutely safe for women in the position. Vaccination is carried out only in vaccination rooms. After the procedure, the specialist should observe the patient's condition for half an hour.
Expert opinion

Indeed, vaccination is capable, if not fully protected from the disease, then significantly reduce the severity of the course of the disease. The vaccine against the flu "Ultriks" has proved itself on the positive side and is popular both among doctors and patients.
