ABSTRACT OBJECTIVES To identify the possible causes of low adherence to vaccination campaigns in Brazil, find and analyze campaigns regarding human papillomavirus (HPV) in Brazil and abroad, and apply quality tools to prepare proposals to increase vaccination coverage (VC) and prevent HPV in the country. METHOD This is a qualitative and deductive-hypothetical research. A narrative review of the literature (especially on the narratives and formats applied in vaccination campaigns in Brazil) was the technique used to develop our method. RESULTS […]

ABSTRACT OBJECTIVE Estimate the future number of hospitalizations from Covid-19 based on the number of diagnosed positive cases. METHOD Using the covid-19 Panel data recorded in Spain at the Red Nacional de Vigilancia Epidemiológica, Renave (Epidemiological Surveillance Network), a regression model with multiplicative structure is adjusted to explain and predict the number of hospitalizations from the lagged series of positive cases diagnosed from May 11, 2020 to September 20, 2021. The effect of the time elapsed since the vaccination program […]

ABSTRACT Due to social distancing guidelines and the displacement of both human and material resources to fight the covid-19 pandemic, individuals seeking healthcare services face certain challenges. Immunization programs have already been a worrisome topic for health authorities due to declines in vaccine uptake rates and are now especially affected by the covid-19 pandemic. Disbelief in science, dissemination of fake news about vaccines, socioeconomic vulnerability and social inequality are some of the challenges faced. This commentary article discusses the impacts […]

ABSTRACT OBJECTIVE: To analyze the risks related to vaccines and the impacts of non-vaccination on the world population. METHODS: This is a narrative review that has considered information present in the bibliographic databases NCBI-PubMed, Medline, Lilacs, and Scientific Electronic Library Online (SciELO), between November 2015 and November 2016. For the analysis of outbreaks caused by non-vaccination, we considered the work published between 2010 and 2016. RESULTS: We have described the main components of the vaccines offered by the Brazilian public […]

ABSTRACT OBJECTIVE To describe the Reference Centers for Special Immunobiologicals and evaluate their implementation considering formal regulations. METHODS We conducted a program evaluation, of evaluative research type. From August 2011 to January 2012, a questionnaire was applied to the 42 Reference Centers for Special Immunobiologicals existing in the Country, approaching the structure, human resources, and developed activities dimensions. We conducted a descriptive analysis of data and used a clustering for binary data with the squared Euclidean distance, by the farthest […]

A very good autogenous vaccine may be obtained by inoculation, in a separate medium, of microorganisms collected from clinical material. A selected culture medium and adequate culture conditions are necessary to stimulate or at least preserve the antigenic properties of microorganisms. The inactivation process must be used carefully in order to prevent damage to existing antigenous contents of the bacteria. A description of a method capable of covering every requirement and which would at the same time be practical and […]

Immunization by BCG is of great effect in developing countries where the incidence of tuberculosis is high. The knowledge that has been acquired in our environment in the last five years has made possible the organization of programmes for BCG intradermic immunization, to a useful epidemiological extent, without a prior tuberculin test. The practice of the integration of intradermic BCG vaccination in the general immunization programmes of the “Geraldo de Paula Souza” Health Unit of S. Paulo University School of […]

The efficacy of oral polio vaccine (OPV) was determired in infants immunized according to the currently recommended vaccination scheme in the city of S. Paulo. Trivalent OPV was administered to the infants at 8 week intervals, begining at 2 months of age, in well controled conditions at the Experimental Health Unit of the Escola Paulista de Medicina. The study showed that the administration of 2 doses of OPV resulted in poor seroresponses and was not sufficient for effective immunization of […]
