“…Despite the demonstrated efficacy of vaccines in reducing mortality and morbidity from communicable diseases, vaccination rates are declining in many areas of the world [ 1 , 2 ], even before the pandemic caused by the SARS-CoV-2 virus became the main topic of newspapers and the subject of passionate debates on social networks and even within families [ 3 , 4 ]. The decision not to be vaccinated is influenced by different reasons, such as forgetfulness or lack of time, concerns about medical interventions that are considered “unnatural”, specific concerns about the safety of vaccines, or mistrust of the motivations of pharmaceutical companies and governments to promote vaccines [ 2 , 5 ].…”

Background: Having a valid tool to assess attitudes toward vaccination and identify the concerns that drive vaccine refusal can facilitate population studies and help guide public health interventions. The objective of this study has been to adapt the Vaccination Attitudes Examination (VAX) scale in Colombian university students and to study its psychometric properties in a non-probabilistic sample of 1074 Colombian university students. Methods: A confirmatory factor analysis was used to study the factorial structure. A structural equation model was tested to study concurrent validity and to check whether the factors predicted having received the coronavirus vaccine. Gender-based measurement invariance was also studied for the best model. Results: The results support the structure of four related factors. The composite reliability index was good for all the factors, but the average variance extracted was not as good for the second factor. There was strong measurement invariance by gender, and two factors are good predictors of being vaccinated or not. Conclusions: The VAX has shown construct and concurrent validity and is a reliable tool for evaluating attitudes towards vaccines in university students in Colombia. It may help guide the implementation of actions for the National Vaccination Plan and institutional policies.

“…ZIKV transmission from mother to child has been shown to cause harm to children during pregnancy or birth; however, less is known regarding transmission through breast milk, given the limited data and publications available [37]. According to the Centers for Disease Control and Prevention [38,39], breastfeeding is an investment in health that generally helps decrease disease risks for infants and mothers. Because of the limited data available regarding the potential risk that human milk might transmit ZIKV, the WHO made a collective decision that the benefits of breastfeeding for the infant and mother outweigh the potential risk of ZIKV transmission.…”

Zika virus (ZIKV) was first discovered in 1947 in Uganda. ZIKV did not receive substantial attention until Brazil hosted the 2016 Summer Olympic Games, and ZIKV reached a global audience. ZIKV is a flavivirus transmitted chiefly through mosquito bites, sexual intercourse and, to a lesser extent, breastfeeding. The recent discovery of how ZIKV causes congenital neurodevelopmental defects, including microcephaly, has led to reevaluation of the importance of the interaction of ZIKV with centrosome organization, because centrosomes play an important role in cell division. When ZIKV disrupts centrosome organization and mitotic abnormalities, neural progenitor differentiation is altered, thereby resulting in cell cycle arrest, increased apoptosis and inhibition of neural progenitor cell differentiation; subsequently, abnormalities in neural cell development can result in microcephaly. To aid in the understanding of the importance of ZIKV infection, this review article provides an overview of its history, transmission routes, pathogenesis, animal models and diagnosis.

“…Vaccination has demonstrated to be one of the most cost-effective health interventions to avoid disease-associated morbidity and mortality, but there are hesitant groups about the clinical development and regulatory process of vaccines [ 20 ]. Vaccine hesitancy refers to a situation where people are doubtful about vaccinations or where they choose to refuse immunizations despite the availability of vaccination services.…”

Acceptability of a Hypothetical Zika Vaccine among Women from Colombia and Spain Exposed to ZIKV: A Qualitative Study

Zika virus (ZIKV) can cause pregnancy loss and congenital Zika syndrome, among other poor health outcomes. The ZIKV epidemic in 2015–2017 disproportionately affected pregnant women in poor-resource settings. We aimed to understand perceptions and attitudes towards a hypothetical ZIKV vaccine, women’s willingness to be vaccinated, and potential barriers and facilitators for vaccine acceptance in 1) migrant women living in Spain who travelled to their countries of origin and were diagnosed with ZIKV infection during pregnancy, and their healthcare providers, and 2) women living in Colombia who delivered a child with microcephaly. An exploratory qualitative study based on phenomenology and grounded theory was conducted. Data were collected through in-depth, paired and semi-structured interviews. Overall, women from both sites were willing to receive a hypothetical ZIKV vaccine. However, some expressed concerns of being vaccinated during pregnancy, yet they would accept it if the vaccine was recommended by a healthcare professional they trust. Main fears towards vaccination were related to vaccine safety and potential adverse effects on child’s health. Women reported feeling hesitant to participate in a ZIKV vaccine trial. These results may contribute to guiding the effective delivery of future ZIKV vaccines among populations most at risk and particularly vulnerable.
