Immunoprophylaxis
Why do you need a vaccine against hepatitis B?
Hepatitis B is among the top ten infections with the maximum number of fatal cases. Every year, 4 million cases of acute hepatitis B and about 1 million deaths from developed cirrhosis or liver cancer are registered in the world.
In Kazakhstan, vaccination against viral hepatitis B has been introduced since 1998. In connection with vaccination of the population of Kazakhstan from viral hepatitis B, over the past 20 years, the incidence rate in the Republic has been reduced by 23.7 times, and among children - 52 times!
It should be remembered that viral hepatitis "B" is especially dangerous for children, since the disease often occurs without clinical manifestations, and up to 90% of infected children become chronic carriers of the virus. Chronic viral hepatitis "B" is characterized by a progressive course, the development of connective tissue, liver replacement cells, impaired function of the organ and the subsequent development of liver cirrhosis.
Viral hepatitis "B" is distributed in various ways: through injections with non-sterile instruments, sexually, when using common household items with a sick person. Pregnant women suffering from chronic hepatitis "B", can transmit the virus to the newborn.
There are no drugs for the treatment of the acute form of viral hepatitis "B". Only supportive care is recommended. Therefore, in many countries of the world they prefer to prevent the infection of children with this infectious disease with the help of vaccination.
The vaccine complex against viral hepatitis B consists of three immunizations up to the age of 12 months. The child receives the first vaccination in the maternity hospital. Now it is recommended to vaccinate within the first 12 hours from the moment of birth (if there are no contraindications, no time is required for observation). In Kazakhstan, subsequent vaccinations against viral hepatitis "B" children receive at the age of 2 and 4 months.
In the Karaganda region for the period from 2011 to 2016 in the region there was not a single case of children with hepatitis B.
In 2017 a teenager vaccinated with a vaccination schedule violation.
Over the entire period of vaccination against hepatitis B, there are no adverse effects after immunization associated with the vaccine!
