conclusions hbv in children due to vaccination failure was resulted from vertical transmission. hbv pre-s/s gene mutations were prevalent and could occur before or after vaccination. therefore, simply analyzing mutation frequency of hbv gene was not of value. to advance blocking hbv vertical transmission, future studies should focus on specific mutation sites, potentially associated with vaccin...
BACKGROUND Two-dose varicella vaccination is recommended for optimal control of varicella in populations with high (>90%) 1-dose coverage. Optimal timing of the second dose may depend on whether breakthrough varicella results from primary vaccine failure (no protective immunity after vaccination) or secondary vaccine failure (waning protective immunity). METHODS Published literature (1995 to ...
Ensuring the adequacy of response to rabies vaccination in dogs is important, particularly in the context of pet travel. Few studies have examined the factors associated with dogs' failure to achieve an adequate antibody titer after vaccination (0.5 IU/ml). This study evaluated rabies antibody titers in dogs after primary vaccination. Dogs under one year of age whose serum was submitted to a re...
Major histocompatibility complex (MHC) class II deficiency is a primary immunodeficiency disease characterized by abnormality of MHC class II molecules surface expression on peripheral blood lymphocytes and monocytes. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as SCID (severe combined immunodeficien...
BACKGROUND Heart failure (HF) is associated with frequent decompensation and admissions to the emergency service. Influenza (INF) and Pneumococcal (pneumonia) vaccinations are recommended in the guidelines, however, respiratory infections are the third leading cause of hospitalization in heart failure. OBJECTIVE To assess the frequency of vaccination against INF and PNM in patients with HF in...
