Hepatitis B cases in the State of São Paulo fell 17% last year compared to 2015, according to a survey by the State Department of Health. 95% vaccine and a campaign this month tries to reach the goal. In 2019, Brazil registered the worst coverage rates among the main vaccines for babies, as shown by the Estadão.

The disease is caused by the hepatitis B virus and the infection can occur through unprotected sexual contact, use of contaminated objects, such as nail pliers, syringe sharing, use of non-sterile material when getting tattoos or putting piercings, and also from the mother to the baby. Last year, 2,564 cases were recorded. In 2015, there were 3,097. The disease is silent and can trigger serious problems, including cancer.

“The infection can go unnoticed, with an evolution of 10 to 20 years, but the treatment can be done at any time and must be done early so as not to progress to liver fibrosis, cirrhosis and cancer”, explains Tatiana Lang D ‘Agostini, director of the Epidemiological Surveillance Center (CVE). The disease has no cure, but it can be controlled with medication.

In the severe phases, the patient may present symptoms such as fatigue, nausea, vomiting, lack of appetite, weight loss and yellow skin and eyes (jaundice). Getting the vaccine is the best way to prevent the disease. “The vaccine is taken at birth and at 2, 4 and 6 months of life. It has been on the child’s calendar since 1998 and, since 2016, it has been offered to all age groups. ”

Immunization is done with the pentavalent vaccine, which is available in the Unified Health System (SUS) and also protects against diphtheria, tetanus, whooping cough and Haemophilus influenza type b (Hib). Three doses are applied. The interval for the second dose is one month after the first and, for the third, it is six months.

“It is a safe vaccine that has been used for decades and is universally available. With the three basic doses, you don’t have to take them again. If the person has lost the wallet, the ideal is to try to retrieve this record at the vaccination post. If it is not possible, you will have to vaccinate again ”, says Núbia Araujo, director of Immunization at the secretariat.

Government campaigns for various vaccines for children and adolescents

According to Núbia, the immunization coverage of the State’s immunizer is 85%, below the 95% target, but the folder intends to achieve it in a campaign that is being carried out this month. “There is little left. We are in a multivaccination campaign for children and teenagers under the age of 15 and we hope to reach the goal now in October, which is an opportunity to update the vaccination portfolio. ”

At the beginning of the month, the State started a vaccination campaign against polio and will offer another 13 immunizers to update the handbook of children and adolescents up to 14 years old. The mobilization will take place until the 30th and the D-day will be next Saturday, the 17th.
