New meningococcal vaccine B arrives in Brazil
Vaccine against meningococcal B, a bacterium that causes not only meningitis but also other more serious diseases, has been launched in Brazil. The vaccine should be available by the end of May, first in private clinics. However, the intention is also to enter the official schedule of immunizations.
According to the infectious disease Juarez Cunha, of the Pediatric Society of Rio Grande do Sul, it is necessary to include new vaccines in the children's calendar. "Once the vaccines are included in the calendar, you can quickly see success when, for example, numbers fall," he says.
When the prevention of a serotype is lacking, it becomes more evident, increasing the incidence of this disease. In this way, including the vaccine in the calendar is a hope for the reduction in cases of type B meningitis. Initial laboratory-based studies indicate an effectiveness around 85%, which means an important coverage.
Your introduction will happen first in the private network for individual protection. In infants up to 1 year, the application schedule will be in 3 doses (2, 4 and 6 months), with reinforcement after completing the first year of life. For individuals between 1 and 50 years of age, two doses are indicated, with a two-month interval, with no need for reinforcement. Today, three different immunizations for meningococcal are being done, two to two months after the baby's life and another to three months.
Doctor Juarez Cunha emphasizes the importance of including the new vaccine in the official calendar for adolescents as well. "The recommendation is also to be made at age 19, as adolescents spend more time indoors, which facilitates the transmission of the bacteria that causes the disease," he says. However, the exact age indication for taking the vaccine in adolescence has not yet been confirmed.
Many people experience such severe back pain that they experience difficulties in doing simple activities that are part of the routine, such as driving, shopping, exercising or even work. But in some people, low back pain can even disrupt one of the noblest hours, which is quiet sleep. The human body needs between seven and eight hours of sleep per night to have a great function.
" Of the many types of cardiac arrhythmia, we can draw attention to atrial fibrillation, which has serious risks for the patient: lack of proper treatment can lead to stroke. " With this statement, the cardiologist José Rocha Faria Neto, a professor at the Pontifical Catholic University of Paraná (PUC-PR), makes it very clear why the disease deserves special attention among the problems that the heart can face.
