Intention to vaccinate against influenza among health care workers caring for immunocompromised patients

Surveying willingness toward SARS-CoV-2 vaccination of healthcare workers in Italy

BACKGROUND

Understanding healthcare workers (HCWs) willingness to receive a future vaccination against coronavirus disease 2019 (COVID-19) may be useful.

METHODS

Cross-sectional study, conducted in Italy from September 14^th to November 30^th, 2020, among 811 HCWs who undergo a voluntary antibody-testing for anti-SARS-CoV-2.

RESULTS

The perceived risk level of developing COVID-19, measured on a Likert-type scale ranging from 1 to 10, was 6.6 and it was higher among females, older HCWs, and in those who agreed that COVID-19 is a severe disease. Married/cohabitant, not physicians, and those who needed additional information regarding the vaccination against COVID-19 were more likely to be concerned that COVID-19 vaccination might not be safe. Males, physicians, those who did not have had any symptom compatible with COVID-19, those who agreed that COVID-19 is a severe disease, those who perceived to be at higher risk of developing COVID-19, those who were not concerned about the vaccine's safety, and those who had received information regarding the COVID-19 vaccination from scientific journals expressed willingness to receive vaccination against COVID-19.

CONCLUSIONS

Communication and education targeted to groups with lowest willingness are needed to raise awareness regarding the safety and benefits of the vaccination and to improve vaccine uptake.

Healthcare workers' knowledge, beliefs, and coverage regarding vaccinations in critical care units in Italy

BACKGROUND

Low rates of vaccine coverage have resulted in a resurgence of several vaccine-preventable diseases in many European countries. Routine vaccination of healthcare workers (HCWs) is important to reduce disease transmission, and to promote vaccine awareness and acceptance in the population. The objectives of this cross-sectional study were to investigate knowledge and beliefs about vaccines and to evaluate self-reported immunization coverage with vaccines recommended for HCWs. Additionally, the effects of several factors on these outcomes have been evaluated.

METHODS

A survey was conducted between September and November 2018 among a random sample of HCWs in cardiac, adult, and neonatal critical care units of 8 randomly selected hospitals across the Campania and Calabria Regions in Italy. Multivariate logistic and linear regression analysis has been performed.

RESULTS

A total 531 HCWs returned the questionnaire for a response rate of 54.9%. Based on a vaccination knowledge score ranging from 0 to 9, more than half of the participants (55.4%) knew few of the vaccines recommended for HCWs (≤3 correct answers), 16.2% knew some vaccines (4-6 correct answers), and 28.4% knew most vaccines (≥7 correct answers), and only 13.2% knew all the vaccines recommended for HCWs. However, two-thirds (62.2%) knew that hepatitis B and influenza vaccines were recommended, and this knowledge was significantly higher among females (p < 0.001), among HCWs aged between 50 and 59 years (p = 0.01) compared with those aged < 30 years, and in those who search for information about recommended vaccines for HCWs (p = 0.012). The vaccine knowledge was significantly lower among nurses and nursing supporting staff compared with physicians (p = 0.032). Approximately two-thirds (62.7%) of HCWs considered themselves at risk of contracting vaccine-preventable infectious diseases during their professional practice. High rates of coverage were self-reported for hepatitis B (96.3%), tetanus and pertussis (93.7%), whereas they were lower for measles/mumps/rubella (80.5%), chickenpox (65.3%), and influenza (35.8%). Only 9.2% of HCWs reported prior receipt of all recommended vaccines. Male HCWs were less likely to report prior receipt of all recommended vaccines (p = 0.011). HCWs aged between 30 and 39 years compared with those aged < 30 years (p = 0.001) and those who knew some (p < 0.001) and most (p = 0.007) of all vaccines recommended for HCWs were more likely to self-report to be immunized.

CONCLUSIONS

Additional training about the vaccinations is needed to improve HCWs knowledge and to address specific concerns which may lead to better uptake among this group.
