"I was afraid my baby would be upset with me" - women living with HIV's accounts going through non-breastfeeding in São Paulo, Brazil.

In Brazil prevention of mother to child HIV transmission guidelines recommend formula feeding. This qualitative study, carried out in a public clinic (CEADIPE/UNIFESP), aimed at exploring experiences of breastfeeding avoidance of women living with HIV living in São Paulo. Individual interviews were carried out with the support of a semi-structured questionnaire. Data was analyzed in a thematic approach with the support of AtlasTi®. During the months of January-February 2010, 25 women were interviewed, including women with (n = 12) and without previous breastfeeding experience (n = 13). Major themes identified were: Non-breastfeeding as a trigger for stigmatization, Non-breastfeeding, guilt and coping, Attitudes around non-breastfeeding for women with and without previous breastfeeding experience, and Women's support through non-breastfeeding. In conclusion women interviewed faced challenges related to HIV diagnosis, which got entangled with difficulties with breastfeeding avoidance. Different patterns of reaction and coping could be identified, regardless of mothers' previous breastfeeding experiences. Health systems were key in providing women living with HIV with tailored services and the necessary support.

Active pharmacovigilance of the seasonal trivalent influenza vaccine produced by Instituto Butantan: A prospective cohort study of five target groups.

INTRODUCTION: Active pharmacovigilance studies are pivotal to better characterize vaccine safety. METHODS: These are multicenter prospective cohort studies to evaluate the safety of the 2017 and 2018 seasonal trivalent influenza vaccines (TIVs) manufactured by Instituto Butantan, by means of active pharmacovigilance practices. Elderly, children, healthcare workers, pregnant women, and women in the puerperium period were invited to participate in the study during the 2017 and 2018 Brazilian national seasonal influenza vaccination campaigns. Following immunization, participants were observed for 30 minutes and they received a participant card to register adverse events information. All safety information registered were checked at a clinical site visit 14 days after immunization and by a telephone contact 42 days after immunization for unsolicited Adverse Events (AE) and Guillain-Barré Syndrome (GBS). RESULTS: A total of 942 volunteers participated in the two studies: 305 elderly, 109 children, 108 pregnant women, 32 women in the postpartum period, and 388 health workers. Overall, the median number of AR per participant ranged from 1 to 4. The lowest median number of AR per participant was observed among healthcare workers (1 AR per participant) and the highest among pregnant women (4 AR per participant). Overall, local pain (46.6%) was the most frequent solicited local AR. The most frequent systemic ARs were: headache (22.5%) followed by fatigue (16.0%), and malaise (11.0%). The majority of solicited ARs (96%) were mild, Grades 1 or 2), only 3% were Grade 3, and 1% was Grade 4. No serious AEs, including Guillain-Barré Syndrome, were reported up to 42 days postvaccination. CONCLUSION: The results from the two studies confirmed that the 2017 and 2018 seasonal trivalent influenza vaccines produced by Instituto Butantan were safe and that active pharmacovigilance studies should be considered, when it is feasible, as an important initiative to monitor vaccine safety in the post-marketing period.
