Vaccine Literacy and Hesitancy on routine and travelers' vaccines: a preliminary online survey.

Background: The vast amount of conflicting information during the COVID-19 pandemic might have had a detrimental effect on people's opinions about vaccinations, including groups like travelers. This study aimed at assessing Vaccine Literacy in a sample of the general Italian population, together with antecedents of Vaccine Hesitancy, such as confidence, complacency, and convenience, the so-called "3Cs", and their effects on accepting routine and travelers' vaccines.

Study Design: A specifically designed anonymous questionnaire was created by using Google forms and validated through a face validity process.

Perspectives in the Development of Tools to Assess Vaccine Literacy.

Vaccine literacy (VL) is the ability to find, understand, and evaluate vaccination-related information to make appropriate decisions about immunization. The tools developed so far for its evaluation have produced consistent results. However, some dimensions may be underestimated due to the complexity of factors influencing VL.

Japanese Encephalitis can be devastating.

Japanese encephalitis, caused by the JE virus transmitted by mosquitoes, is the most common type of epidemic encephalitis in Asia. It is endemic in most of South and Southeast Asia, but the number of cases can vary greatly between areas. While many infections do not lead to disease, the symptomatic cases can be very severe and life-threatening.

COVID-19 vaccine literacy: A scoping review.

To address vaccine hesitancy, specific self-rated tools have been developed to assess vaccine literacy (VL) related to COVID-19, including additional variables, such as beliefs, behavior, and willingness to be vaccinated. To explore the recent literature a search was performed selecting articles published between January 2020 and October 2022: 26 papers were identified using these tools in the context of COVID-19. Descriptive analysis showed that the levels of VL observed in the studies were generally in agreement, with functional VL score often lower than the interactive-critical dimension, as if the latter was stimulated by the COVID-19-related infodemic.

Vaccine Literacy and Source of Information about Vaccination among Staff of Nursing Homes: A Cross-Sectional Survey Conducted in Tuscany (Italy).

Vaccine literacy (VL) mediates the transfer of information and facilitates vaccination acceptance. The aims of this study are to validate the HLVa-IT (Health Literacy Vaccinale degli adulti in Italiano—Vaccine health literacy for adults in Italian language) for the staff of nursing homes (NHs), to measure VL in such a peculiar target group, and to assess its relationship with the sources used to obtain information about vaccines and vaccinations. A survey has been conducted in a sample of Tuscan NHs using an online questionnaire.

Italian Adults' Likelihood of Getting COVID-19 Vaccine: A Second Online Survey.

Rapid online surveys are an important tool for tracking the public's knowledge and perceptions during infectious disease outbreaks. In June 2020, during the early phases of COVID-19 vaccines development, we conducted a survey in 885 Italian adults that aimed at assessing their attitudes and opinions about vaccination, in addition to their vaccine literacy levels (i.e.

Assessing COVID-19 vaccine literacy: a preliminary online survey.

The COVID-19 infodemic can be countered by scientific evidence, clear and consistent communication, and improved health literacy of both individuals in need of information and those providing it. A rapid online survey was carried out to evaluate vaccine literacy (VL) skills in the general population and perceptions about COVID-19 vaccine candidates, along with behavior and beliefs about current vaccinations. Observed VL levels were consistent with previous observations - where comparable self-reported tools were administered face-to-face and by paper-and-pencil - the mean functional score being = 2.

Intravescical instillation of Calmette-Guérin bacillus and COVID-19 risk.

It has been theorized that Calmette-Guérin bacillus may prevent or reduce the severity of COVID-19 through a nonspecific stimulation of the immune system. A preliminary assessment of SARS-CoV-2 infection rates and outcomes among 2803 individuals affected with high risk non-muscle-invasive bladder cancer and treated with intra-bladder instillation of BCG, showed no evidence of a protective effect. However, the interpretation of these data need some caution, due to the low prevalence of infection (<1%) observed within this population, along with the fact that intra-bladder administration cannot mirror the usual intradermal administration of BCG, in particular in patients partially immunocompromised.

Vaccine literacy is undervalued.

Despite weak health literacy is considered a concause of vaccine hesitancy, it is rarely taken into account when discussing about this subject. The association between health literacy skills and vaccine acceptance has been shown to be uneven when using general measures, also depending on the population settings and type of vaccine considered. Vaccine literacy has been built on the same idea of health literacy, but very few specific measuring tools have been developed until now.

Assessment of health literacy skills in family doctors' patients by two brief, self-administered Italian measures.

Health Literacy (HL) is an important health determinant: low HL skills result in less healthy choices, riskier behavior, poorer health, less self-management and more hospitalization. An observational study was conducted in a selected population, attending the waiting rooms of family general practitioners, with the aim of assessing HL capabilities through the administration of two HL screeners (IMETER and SILS-IT), and comparing the two measures. An anonymous questionnaire was administered, consisting of the Italian versions of the two tests on a single sheet.

Health literacy, emotionality, scientific evidence: Elements of an effective communication in public health.

The importance of healthcare providers' communication abilities is still underestimated. Informing the population on the basis of documented evidence is essential but not enough to induce a change in the beliefs of who is doubtful or does not accept preventive interventions, such as vaccination. Lining up the offer of prevention to the knowledge of the citizens, also improving Health Literacy skills, is a critical step toward their empowerment and behavior change.

Communication about vaccination: A shared responsibility.

Vaccine hesitancy is an important issue to be addressed, due to the risk of decrease of vaccination coverage and consequent control of preventable diseases. While it is not considered a specific determinant, poor or inadequate communication can contribute to vaccine hesitancy and negatively influence vaccination uptake. As a contribution to the ongoing discussion regarding this theme and in the perspective of the implementation of the upcoming national vaccination plan in Italy, the Erice Declaration was drafted by experts in the field of immunization following a 5-day residential, independent workshop regarding communication topics in vaccinology.

Challenge with hepatitis B vaccine in children previously vaccinated with a hepatitis B-containing combination vaccine.

Introduction: The World Health Organization (WHO) recommends universal infant hepatitis B virus (HBV) vaccination as the most effective preventive measure against HBV-induced disease in endemic areas. More than 160 countries have followed the WHO recommendations to incorporate HBV vaccination in their national infant immunization programs. While antibodies to hepatitis B surface antigen (anti-HBs) concentrations progressively decrease following vaccination in infancy, protection persists, probably due to lasting immune memory.

Safety, tolerability, and immunogenicity of a two-dose regimen of high-titer varicella vaccine in subjects > or =13 years of age.

A new manufacturing process, known as process upgrade varicella vaccine (PUVV) was developed for a refrigerated formulation of varicella vaccine and for an investigational zoster vaccine. Safety and tolerability of a two-dose regimen of high-titered (approximately 50,000 PFU) PUVV were compared to a lower-titer formulation (approximately 5400 PFU) of VARIVAX; in 1366 healthy subjects > or =13 years old. Only one vaccine-related clinical serious adverse experience (pruritus; no hospitalization) was reported, in the VARIVAX group.
