    Abstract ABSTRACT In February 2020, a Chinese cargo ship docked at the Port of Santos with reports of crew members with a feverish and respiratory condition. A team was gathered to verify the existence of suspected cases of COVID-19 inside the vessel and define its clearance. All 25 crew members were interviewed, and no suspected cases were found. The vessel was then cleared for port activities. The investigation resulted from the implementation of the contingency plan to face a public health emergency of international importance and several surveillance entities cooperated.

    Abstract ABSTRACT Twenty-seven children aged seven months to 5 years were inadvertently vaccinated with a COVID-19 vaccine, the CoronaVac (Sinovac, China), an inactivated SARS-CoV-2 vaccine, in two different cities of Sao Paulo State, Brazil. After the event, these children were monitored by local pediatricians and serum samples were collected at the first visit and 30 days after vaccination and tested for SARS-CoV-2 S1 serology with Ortho total IgG anti-S1 protein and Cpass, an ACE2 receptor binding domain inhibition assay. Only one child had a mild symptom after vaccination, with no other adverse events documented up to the 30 days follow-up. Of 27 children tested 3-9 days after vaccination, 5 (19%) had positive serology suggesting a previous natural SARS-CoV-2 infection, with all 19 tested on day 30 after vaccination and presenting with positive tests, with an increment of antibody titers in those initially positive. A low Cpass binding inhibition was observed in the first collection in 11 seronegative cases, with high titers among those anti-S1 positive. All children showed an important increase in antibody titers on day 30. The event allowed the documentation of a robust serological response to one dose of CoronaVac in this small population of young children, with no major adverse effects. Although it was an unfortunate accident, this event may contribute with future vaccine strategies in this age group. The data suggest that CoronaVac is safe and immunogenic for children.

    Abstract Abstract INTRODUCTION: The state of São Paulo has been monitoring cases of microcephaly and pregnant women presenting with acute rash, through CeVeSP. METHODS: This was a descriptive study focusing on pregnant women with rash and the outcome of their pregnancy, based on the notifications through the CeVeSP. RESULTS: During 2016, 2,209 cases of pregnant women with rash were reported and investigated. Of these, 36.6% were confirmed. Of the pregnant women who tested positive for ZIKV, 6.4% did not have a favorable outcome. CONCLUSIONS Our results allowed the characterization of pregnant women exposed to ZIKV and the outcome of pregnancy.

    Abstract OBJETIVOS: Apresentar uma revisão atualizada sobre os estudos de eficácia, eventos adversos e esquema vacinal da vacina contra varicela e a nova apresentação combinada com a vacina contra sarampo, caxumba e rubéola. FONTES DOS DADOS: Revisão bibliográfica utilizando a base de dados MEDLINE e LILACS no período de 1999 a 2006. SÍNTESE DOS DADOS: A vacina contra varicela tem uma eficácia entre 70 a 90% contra a infecção e 95 a 98% de proteção contra as formas graves. É uma vacina bem tolerada e pouco reatogênica. Após o seu licenciamento, foram comprovados apenas três casos de transmissão do vírus vacinal de pessoas previamente saudáveis para contatos domiciliares, que desenvolveram doença leve. Apesar das evidências de que a proteção conferida pela vacina pode diminuir com o passar dos anos, ainda não é possível afirmar que seja necessário, no momento, a aplicação de uma segunda dose, tendo em vista a exposição ao vírus selvagem. Após a vacinação universal, as chances de estímulo natural deverão diminuir, e muito provavelmente será necessário a aplicação de doses de reforço. Recentemente foi licenciada a vacina quádrupla viral, um produto combinado com a vacina contra sarampo, caxumba, rubéola e varicela com elevadas taxas de soroconversão. CONCLUSÃO:A vacina contra varicela é recomendada pela Sociedade Brasileira de Pediatria (SBP) para as crianças a partir de 1 ano de idade. Esperamos que, em breve, a vacina quádrupla viral esteja disponível no Brasil, pois o uso de vacinas combinadas possibilita uma maior cobertura vacinal. OBJECTIVES: To present an up-to-date review of studies investigating the efficacy, adverse events and vaccination regimens of the varicella vaccine and the new presentation combined with the vaccine for measles, mumps and rubella. SOURCES OF DATA: Bibliographic review of the MEDLINE and LILACS databases covering the period 1999 to 2006 SUMMARY OF THE FINDINGS: The varicella vaccine protects 70 to 90% of immunized children against any form of varicella zoster infection, but the efficacy against severe forms is higher (95 to 98%). This is a well-tolerated vaccine that causes few reactions. Since the vaccine was licensed, there have been three confirmed cases of transmission of the vaccine virus by domestic contacts to previously healthy people, who went on to develop mild disease. Despite evidence that the protection offered by this vaccine can wane over a number of years, it is not yet possible to state that a second dose is warranted, bearing in mind exposure to wild virus. After universal vaccination the chances of natural stimulation should drop and it is very probable that booster doses will become necessary. A measles, mumps, rubella, and varicella vaccine has recently been licensed that combines vaccines for measles, mumps, rubella and varicella in a single product with high rates of seroconversion. CONCLUSIONS: The Brazilian Society of Pediatrics recommends the varicella vaccine for children from 1 year on. We hope that the measles, mumps, rubella, and varicella vaccine will soon be available in Brazil, since combined vaccines facilitate wider vaccination coverage.

    Abstract Following introduction of routine infant rotavirus vaccination, severe diarrhea hospitalization rates declined among children aged <5 years throughout Brazil. Ensuring equity of rotavirus vaccine impact is important in countries that self-finance immunization programs. The objective of this study was to examine rotavirus vaccine impact on diarrhea admission rates among children aged <5 years in Brazil's public health system, according to area-based measures of human development in the state of São Paulo, Brazil.Ecological analysis of public health system hospitalization rates for acute gastroenteritis among children aged <5 years in the state of São Paulo, Brazil, according to five categories of municipal development based on a modified Human Development Index for municipalities. Acute gastroenteritis hospitalization rates among children aged <5 years after national rotavirus vaccine introduction (2008–2011) were compared to rates in pre-vaccine years (2000–2005) to calculate percent decline in rates (1−rate ratio) and 95% confidence intervals (CI) for each municipal development category. Direct hospitalization costs during the two periods were compared.Annual rates declined by 40% (95% CI, 39–42%) from 631 diarrhea hospitalizations per 100,000 person years pre-rotavirus vaccination to 377 per 100,000 post-vaccination among children aged <5 years and 50% (95% CI, 48–52%) from 1009 to 505 per 100,000 among infants. Highest rates were observed in least developed municipalities. Significant declines of 26–52% among children <5 years and 41–63% among infants were observed in all categories of municipal development. Lower diarrhea hospitalization rates resulted in annual savings of approximately 2 million USD for the state of São Paulo. Savings in direct hospitalization costs benefitted municipalities in all five categories.The introduction of rotavirus vaccination was associated with substantial reductions of diarrhea-related admissions at all levels of municipal development in São Paulo State, Brazil.

    Abstract We propose a method to analyse the 2009 outbreak in the region of Botucatu in the state of São Paulo (SP), Brazil, when 28 yellow fever (YF) cases were confirmed, including 11 deaths. At the time of the outbreak, the Secretary of Health of the State of São Paulo vaccinated one million people, causing the death of five individuals, an unprecedented number of YF vaccine-induced fatalities. We apply a mathematical model described previously to optimise the proportion of people who should be vaccinated to minimise the total number of deaths. The model was used to calculate the optimum proportion that should be vaccinated in the remaining, vaccine-free regions of SP, considering the risk of vaccine-induced fatalities and the risk of YF outbreaks in these regions.
