Introduction: Since the end of 2014, Zika virus (ZIKV) infection has been rapidly spreading in Brazil. Methodology: To analyze the possible association of yellow fever vaccine with a protective effect against ZIKV-related microcephaly, the following spatial analyses were performed, using Brazilian municipalities as units: i) yellow fever vaccination coverage in Brazilian municipalities in individuals aged 15-49; ii) reported cases of microcephaly by municipality; and iii) confirmed cases of microcephaly related to ZIKV, by municipality. SaTScan software was used to identify clusters of municipalities for high risk of microcephaly. Results: There were seven significant high risk clusters of confirmed microcephaly cases, with four of them located in the Northeast where yellow fever vaccination rates were the lowest. The clusters harbored only 2.9% of the total population of Brazil, but 15.2% of confirmed cases of microcephaly. Conclusion: We hypothesize that pregnant women in regions with high yellow fever vaccination coverage may pose their offspring to lower risk for development of microcephaly. There is an urgent need for systematic studies to confirm the possible link between low yellow fever vaccination coverage, Zika virus infection and microcephaly.

ABSTRACTBackgroundImmunization against COVID-19 in Brazil started in January 2021, with health workers and the elderly as the priority groups. We assessed whether there was an impact of immunizations on the mortality of individuals aged 80+ years.MethodsBy April 22, 2021, 147,454 COVID-19 deaths had been reported to the Brazilian Mortality Information System. Denominators for mortality rates were calculated by correcting population estimates for all-cause deaths reported in 2020. Proportionate mortality at ages 80+ and 90+ years relative to deaths at all ages were calculated, and mortality rate ratios compared these two age groups with individuals aged 0-79 years. Vaccine coverage data were obtained from the Ministry of Health vaccination monitoring website. All results were tabulated by two-week periods from epidemiological weeks 1-14, 2021.FindingsAs the P.1 variant spread throughout Brazil, the total number of deaths increased over time starting in epidemiological week 9 of 2021. The proportion of all deaths occurring at ages 80+ years was over 25% in weeks 1-6 and declined rapidly to 13.1% in weeks 13-14. Mortality rates were over 13 times higher in the 80+ years age group compared to that of 0-79 year olds up to week 6, and declined to 6.9 times in weeks 13-14. Coronavac accounted for 77.3% and AstraZeneca for 15.9% of all doses administered. Vaccination coverage (first dose) increased rapidly among individuals aged 80+ years, reaching 49.1% in weeks 5-6 and over 90% after week 9.InterpretationRapid scaling up of vaccination coverage among elderly Brazilians was associated with an important decline in relative mortality compared to younger individuals, in a setting where the P.1 variant predominates. Had mortality rates among the elderly remained proportionate to what was observed up to week 6, an estimated additional 13,824 deaths would have been expected up to week 14.

Relapsing Remitting Multiple Sclerosis

Background: Yellow fever vaccine (YFV) is not advised for multiple sclerosis (MS) patients because of the potential risk of post-vaccine relapses. Objective: To assess the risk of relapsing-remitting multiple sclerosis (RR-MS) worsening after YFV. Methods: Non-interventional observational retrospective, exposed/non-exposed cohort study nested in the French national cohort including MS. Results: 128 RR-MS were included. The 1-year annualized relapse rate (ARR) following YFV did not differ between exposed: 0.219 (0.420) and non-exposed subjects: 0.208 (0.521) ( p = 0.92). Time to first relapse was not different between groups (adjusted hazard ratio (HR) = 1.33; 95% confidence interval (CI) = 0.53–3.30, p = 0.54). Conclusion: These results suggest that YFV does not worsen the course of RR-MS.

AbstractIntroductionOn August 13, 2021, India completed 30 weeks of vaccination against COVID-19 for its eligible citizens. While the vaccination has made progress, there has been no study analyzing the federal/union vaccine policy and its effect on vaccination coverage across Indian states. In this context, this study analyses the federal vaccination policy and its effect on interstate variation in vaccine coverage and the correlation of state economy with vaccination coverage.MethodsThe study analyses vaccine policy documents, secondary data on vaccination coverage and state gross domestic product (GDP) available in public domain. ANOVA test has been used to assess the effect of vaccine policy on interstate vaccine coverage and correlation-regression analysis has been conducted to assess the type and strength of association between gross state domestic product and vaccination coverage.ResultsInterstate variation in vaccination coverage in the first 15 weeks was the least (F=3.5), when vaccine procurement and supply was entirely provided by the union/federal government and vaccination was limited to priority groups. However, with the extension of vaccine policy to other groups and reduction in federal government involvement in vaccine procurement, the interstate variation in vaccination coverage increased significantly (F=10.74) by the end of 30 weeks. The highest interstate variation was observed in the period between 23-30 weeks (F=25.31). State GDP was positively and strongly correlated with state vaccination coverage with a high coefficient of correlation (R=0.94) and high coefficient of determination (R2= 0.88).ConclusionsThe study finds that federal procurement and supply of vaccination among prioritized groups has been the best strategy till date to address the inequity in vaccination coverage across the states of India.

Coverage Rates

Although several national and international recommendations have been published, influenza vaccinations are carried out too rarely and thus vaccine coverage rates, both in the general population and in risk groups, remain at an unsatisfactorily low level. The paper presents the current data describing influenza vaccine coverage rates in different countries, in the general population and risk groups (including patients with chronic diseases, pregnant women, children the elderly) and health care workers. It is emphasized that there are many limitations related to the estimation of coverage rates. Methods that are currently used for the assessment of influenza vaccination coverage rates include the following: an analysis of data from health care facilities or providers, from national health insurance records, from well-documented national or private vaccine programs targeting at specific smaller groups, evaluation of national vaccine register, and national surveys of individuals. The establishment of coverage rates among specific groups usually requires another approach with the use of individual web- or telephone- based surveys, which is why selection bias and recall bias should be taken into consideration while discussing the results. The most common drivers and barriers for influenza vaccination are also identified and presented in the review.

National Immunization

Brazil has the National Immunization Program for disease prevention that offers nineteen vaccines, yet it is known that vaccination coverage according to age is not always reached. Thus, this study aimed to evaluate the vaccination coverage in the municipality of Sinop, in the Mato Grosso state and in the Brazil for meningococcal C conjugate vaccines and Hepatitis B in the period from 2015 to 2019. Method: This is a descriptive, retrospective and cross-sectional study, with data available in the Information System of the National Immunization Program. Results: Vaccination coverage for mingococcal C in children under one year in Sinop was above the target in 2015 and 2018, Mato Grosso was above only in 2015, for the booster dose only Sinop was above the target in 2016. Coverage for hepatitis B in children under 30 days of life demonstrated that Sinop had coverage above the state of Mato Grosso, which in turn was above Brazil. For children under 1 year old, only in 2016 and 2019 the state presented greater vaccination coverage at the expense of Sinop and Brazil. Conclusion: The results demonstrate that there is hesitation on the part of the population regarding vaccination, being greater in vaccines such as meningococcal C. Strengthening childcare is the key to improving the panorama of vaccine coverage.
