Why do you need to vaccinate against chickenpox
The causative agent of Varicella Zoster – is highly virulence and transmitted by airborne drip. That is why chickenpox is sick mainly children, closely communicating among themselves in preschool and school educational institutions. In most cases, the disease proceeds easily enough: temperature, itchy bubble rash and other symptoms pass in seven to 10 days. After recovery, persistent immunity occurs, so the chance of reinfecting chickenpox is extremely low.
However, in some cases (usually in weakened children, as well as adolescents and adults) chickenpox can give serious complications. These include chickenpox pneumonia, arthritis, encephalitis and meningitis. Also, the virus can harm the cardiovascular, genitourinary, nervous and immune systems. The course of chicken pox is often unpredictable, so it is better to protect yourself from it by getting vaccinated in advance.
There is not only routine, but also emergency vaccination for chickenpox. It is possible to prevent infection by getting vaccinated within three days after contact with a sick person.
What vaccines for chickenpox are in Russia
Far from all existing vaccines against chickenpox are allowed for use in Russia. At the moment it is possible to inoculate against chickenpox only with vaccines “Varilrix” and “Okavax”. Both have high efficiency and can be used in adults and children who have reached the age of one year.
Immunization with the Varilrix vaccine for children under 13 years of age is performed once. After this age, two doses of the drug are required to develop persistent immunity to chickenpox. The interval between the administration of the vaccine in this case should be one and a half to two months and, if possible, not exceed 10 weeks. Contraindications for vaccination include immunodeficiency conditions, infectious diseases, chronic diseases in the exacerbation stage, breastfeeding period and individual intolerance. It is also not possible to use the drug during pregnancy, as well as three months before the planned conception.
Before administration of the chicken pox vaccine, a doctor should be examined to ensure that there are no contraindications.
The vaccine “Okavax” has an advantage over “Varilrix”: only one dose of the drug is sufficient to develop persistent immunity for both children and adults. Otherwise, there is virtually no difference in indications and contraindications for vaccination. Despite the fact that both Russian-registered vaccines are well tolerated and rarely cause complications, entrust the choice of the drug is better to the doctor.
