Vaccination as prevention gripability and terrible flu

Flu viruses are rapidly spread by airborne droplets through sneezing, coughing and even talking. Possible transmission of the disease through personal belongings, household items, and toys. From the moment of infection before occurrence of first symptoms is from 2 to 5 days, the patient dramatically increased body temperature to 39 degrees and above. The person becomes irritable, he has headaches, aching joints and muscles, lethargy, fatigue. A few days after the beginning of flu, cough and slight runny nose. These late and not very clear signs, perhaps the most important distinction of influenza from other viral infections that affect the respiratory system. The flu is not an intestinal disorder, if they arise, then – there was still some kind of infection, or the body reacts to the treatment.

The severity of the flu depends on many factors: General health and age of the patient whether it is infected with the virus previously. To paraphrase a saying – Not so devil as his baby – we can say that the effects and complications of the flu is much more dangerous than the disease itself. In some cases it causes severe damage to cardiovascular system, lungs and even the brain. Flu dramatically reduces immunity and can cause death in elderly and children.

The flu is dangerous for everyone. Kids are defenseless against him because you don’t have time to produce antibodies, the elderly – because their antibodies do not work due to the weakening of the immune system. The main feature of the flu that the ill person is still susceptible to re-infection, because the virus of the disease is very variable.

Which influenza vaccine to choose?

By far the most effective means of preventing influenza is universally recognized as an annual vaccination. In Russia, the optimal time for this procedure is October-November. As the virus active in our country from December to March, with full immunity after vaccination, it is time to emerge.

Vaccination against influenza

The vast majority of cases, vaccines would be administered the injection, but there is an alternative way – through the nasal mucosa. This reduces the risk of undesirable consequences, and formed the local immunity. Unfortunately, this method is acceptable only for single vaccines.

For the prevention of influenza use live (weakened) viruses, and inactivated vaccines with dead viruses of the pathogen. The latter are divided into consist of whole (contain whole viruses), split (split vaccine) (from virus to get all the protein that provides fewer side effects after flu shots) and subunit (uses only surface proteins, most required for the formation of protection against influenza).

According to a recent research of Russian scientists, inactivated vaccines have good tolerability and high epidemiological efficiency. Along with other vaccines approved for use in Russia, extensively used inactivated “influvak” (Holland) and “Vaksihryp” (France). All the above products meet the requirements of the European Pharmacopoeia (level of protection over 70%) are effective drugs for the prevention of influenza. To an inactivated split vaccines also include “Flyuaryks” (Belgium), “Begrivac” (Germany), “Grippol” (Russia) and “Agrippal” (Germany).

Who should get a flu shot?

Influenza vaccination required for children. attending children’s institutions. Influenza vaccination is required of kids aged 6 months to 3 years, often ill children who attend children’s institutions. Vaccination should hospital patients, people with chronic diseases and impaired immunity, persons older than 65 years. In this population the incidence is almost 10 times higher than in other age groups, and the vaccine not only protects against flu, but also reduces the frequency and severity of heart attacks and strokes. Should be vaccinated annually the staff of hospitals and clinics, teachers and personnel of childcare institutions. Be sure to vaccinate if you have to have contact with kids under the age of six months.

Inactivated vaccines are administered from 6 months intramuscularly or deep subcutaneously, kids in the front upper thigh, adults and adolescents in the deltoid muscle of the shoulder. Influenza vaccination can be combined with any other vaccinations (except BCG TB).

Contraindications to influenza vaccination: hypersensitivity to egg protein or other components of the vaccine, exacerbation of chronic diseases.

The pros and cons of flu vaccination

Despite all the exhortations of doctors, many people to this day believe that the best medicine against flu – tea with raspberry jam. These irresponsible and uneducated from a medical point of view of the citizens seriously risk not only their health but also the health of their children and even their lives.

The greatest threat the flu and its complications pose for kids starting from 6 months of age, which pick up the virus in 3,5 times more often than adults. In children aged 6 months to 2 years very high probability of complications due to violations of the cardiovascular and Central nervous system. In 40% of cases, the flu leads to otitis media and, as a consequence, deafness! Remember that next time you refuse to vaccinate a child. Are you really willing to deprive him of the right to a healthy and fulfilling life?

According to statistics, about 85 % of vaccinated kids are totally resistant to influenza viruses, and those still ill, carry the disease much easier in a shorter time and without complications. Weighty argument, isn’t it?

Many people recklessly refuse vaccines because they are afraid of complications. And in vain, because side effects while using highly purified subunit vaccines the 3rd generation (“influvak”, “Agrippal” and “Grippol”) are minimised. And the best proof indications. These vaccines are allowed to cultivate six-month-old children and pregnant women.

It happens that in the first days after vaccination, fever (usually no more than 37.5 degrees), there are chills and weakness but this is only the General reaction. It occurs only in about 1% of children who are vaccinated, and quickly. 4% of babies after vaccination at the injection site observed painful redness and swelling, which disappear within two days. Doctors authoritatively declare that severe complications after vaccination in recent years was not!

The debate about the benefits and dangers of flu vaccinations don’t stop by until the last virus of this disease will not disappear from the face of the Earth. How many people, so many opinions, and only you can decide whether to get vaccinated or not. In any case, if you made a decision “for” or “against”, it is necessary to take into account all contraindications. Especially when it comes to the health of your own child!
