Abstract
Debate regarding vaccinating high-risk infants with penta- and hexavalent vaccines persists, despite their good immunogenicity and acceptable safety profile in healthy full-term infants. We report the findings of a systematic literature search that aimed to present data on the immunogenicity, efficacy, effectiveness, safety, impact, compliance and completion of penta- and hexavalent vaccination in high-risk infants, including premature newborns. Data from the 14 studies included in the review showed that the immunogenicity and the safety profile of penta- and hexavalent vaccines in preterm infants was generally similar to those seen in full-term infants, with the exception of an increase in cardiorespiratory adverse events such as apnea, bradycardia and desaturation following vaccination in preterm infants. Despite recommendations of vaccinating preterm infants according to their actual age, and the relatively high completion rate of the primary immunization schedule, vaccination was often delayed, increasing the vulnerability of this high-risk population to vaccine-preventable diseases.

Midwives' Knowledge, Attitudes, and Practice Regarding COVID-19 Vaccination for Pregnant Women: A Nationwide Web-Based Survey in Italy. Vaccines (Basel) 2023; 11:vaccines11020222. [PMID: 36851098 PMCID: PMC9961665 DOI: 10.3390/vaccines11020222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/07/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
Abstract
This cross-sectional survey investigated the knowledge, attitudes, and practices concerning the COVID-19 vaccination for pregnant women among midwives in Italy and the associated factors. Midwives with at least five years of midwifery education and who had received information about the COVID-19 vaccination from official government organizations or scientific journals were more likely to know in which trimester this vaccine can be administered. A higher perceived utility of this vaccination was observed among midwives working in the public sector, in those concerned by being infected by SARS-CoV-2, who have received at least one dose of this vaccination, in those who considered COVID-19 a severe disease for pregnant women and their fetus, and who believed that the vaccination is safe. One-third of the midwives routinely provided information and half recommended this vaccination. Midwives with more years of activity, who received information about the vaccination from official government organizations or scientific journals, those who had never assisted patients with SARS-CoV-2, and those who believed in midwives' role in COVID-19 prevention were more likely to routinely provide information. Participants who perceived a higher utility of this vaccination, those who believed in midwives' role in COVID-19 prevention, those who received information from official government organizations or scientific journals were more likely to routinely provide a recommendation for the vaccine. Midwives' knowledge must be improved for ensuring that they communicate and recommend the vaccination to their patients.
