The objective of this study is to identify the determining attitudinal, behavioral, and sociodemographic factors behind the vaccination decision of parents and guardians in Brazil regarding immunization of children against COVID-19. Our data is obtained from a national online survey of 1,872 parents or guardians of children between 5 and 11 years of age, conducted from May 16 to 25, 2022. Our results show that, in Brazil, the decision to vaccinate children against COVID-19 is better explained by attitudinal and behavioral factors than sociodemographic ones. More precisely, the choice to immunize children against COVID-19 is strongly associated with the parents or guardians' own COVID-19 vaccination status, their ambivalence regarding this decision, their political preferences, and media use. In particular, parents and guardians who did not vaccinate against SARSCov2 and who supported former president Jair Bolsonaro (the main anti-vaccine political leader in the country during the COVID-19 pandemic) were substantially less likely to vaccinate their children. Parents and guardians with greater exposure to the country's major TV news program (Jornal Nacional/TV Globo), however, were more likely to do so. Other findings show that evangelicals - whose religious leaders strongly supported the former president -, young parents and guardians, and those from lower economic status were also less likely to vaccinate their children.

• Vaccination uptake and intention to vaccinate is generally high in Brazil. • Brazilians are less likely to vaccine when the country of origin of a COVID-19 vaccine is mentioned. • Chinese and Russian developed-vaccines are the vaccines most rejected. • Current President Jair Bolsonaro is a COVID-19 denier and has specifically expressed negative views about China, the Chinese-developed vaccine and vaccination, in general. • Rejection of the Chinese-developed vaccine is particularly strong among those who have positive evaluations of President Jair Bolsonaro. This study examines the effect of the country of origin of the vaccine on vaccination acceptance against COVID-19. More specifically, we show how the political context in Brazil has affected acceptance of vaccines produced in China, Russia, the US, and England at the University of Oxford. Our data come from a survey experiment applied to a national sample of 2771 adult Brazilians between September 23 and October 2, 2020. We find greater rejection among Brazilians for vaccines developed in China and Russia, as compared to vaccines from the US or England. We also find that rejection of the Chinese-developed vaccine is particularly strong among those who support President Jair Bolsonaro—a COVID-19 denier and strong critic of China and vaccination, in general.

This article analyzes 156 pre-election surveys conducted in 2010 on candidates for President and Governor in the 27 Brazilian Federal Units. The main objective is to describe and explain differences between survey and ballot results. The study uses Mosteller's Method 3 (MM3) to calculate the overall accuracy of each pre-election survey and suggests the Candidate Error Estimation Method (MEEC) to investigate a possible bias against a party or a group of parties during that election. The results show errors greater than that informed to Brazilian electoral authorities but do not justify calling into question the accuracy or partisan neutrality of the whole set of surveys analyzed. Greater differences were found: i) in surveys conducted many days before the vote, ii) during the first round, iii) in low competitive races, iv) when there were few candidates and v) in elections for Governor.
