Purpose: The incidence of Lebanese adults suffering from serious health problems due to diseases for which vaccines are available is increasing every year. Vaccination is the most effective strategy for preventing such diseases and their complications. People of 18 years of age and older are recommended to receive certain vaccines based on their stage of life, medical status, lifestyle, and other contemplations. This study was designed to evaluate factors independently associated with Lebanese population awareness of CDC (center for disease control and prevention) recommended adult’s vaccinations and vaccine-preventable diseases for the first time in Lebanon
Methods: This was a community based cross-sectional study conducted from December 2018 till June 2019. Out of 1000 screened participants, a representative sample of 600 subjects aged 18 years old and above, and residing in the six districts of Lebanon were examined to assess their awareness of selected vaccine-preventable diseases and adult vaccinations including influenza, pneumococcal, tetanus, diphtheria, pertussis (Tdp), human papillomavirus (HPV), herpes zoster, measles, mumps, rubella (MMR), hepatitis A and B, along with their self-reported vaccination status. Data collection form was filled up through one on one interview with the main investigators and each participant alone. IBM SPSS 20 (Statistical Package for Social Sciences) was used for data analysis. All analyses were weighted to reflect the Lebanese adult population. T-tests were used to identify the differences in vaccination status and awareness of adult vaccinations and vaccine-preventable diseases by the selected covariates. A multivariable logistic regression model with a predictive marginal approach was used to identify independently associated factors with awareness of selected vaccine-preventable diseases and vaccines status among adult populations. A two-sided significance level of 0.05 was adopted for all statistical tests.
Results: Among the surveyed population, 75.5% agreed that adults’ vaccination is good for health. The percentage of adults who reported taking adults’ vaccines as recommended by the CDC ranged between 9.9% to 28.8% (Tdp vaccine14%, influenza vaccine 28.8%, MMR vaccine 15.2%, zoster vaccine12.9%, HPV vaccine for males 9.9%, HPV vaccine for females11.9%, pneumococcal vaccine13.6%, hepatitis A vaccine12.6%, hepatitis B vaccine 10.5%, meningococcal vaccine 11.9%, haemophilus influenza b vaccine 13.7%). Awareness of vaccine-preventable diseases ranged from 47.7% to 88.9% (88.9% reported awareness of influenza, 61.1% reported awareness of tetanus and pertussis, 61.3% reported awareness MMR, 53.8% reported awareness of varicella zoster, 47.7% reported awareness of HPV, 64.2% reported awareness of hepatitis A, and 62.5% reported awareness of hepatitis B, 58.8% reported awareness of meningitis). Awareness of the corresponding vaccines ranged from 38% to 69.5% (Tdp vaccine 38%, influenza vaccine 69.5%, MMR vaccine 40.2%, Zoster vaccine 46.4 %, HPV vaccine for male 50.1%, HPV vaccine for female 55.8%, pneumococcal vaccine 46,2%, hepatitis A vaccine49.4%, hepatitis B vaccine 47.2%, Meningococcal vaccine 43.2%, haemophilus influenza b vaccine 44.4%). In multivariable analysis, being female, married, college graduate and a health care provider were significantly associated with higher awareness levels.
Conclusion: Despite the relatively high level of awareness of most of vaccine preventable diseases, the awareness for available vaccines and recommended vaccination schedule was modest. Furthermore the self-reported vaccination coverage was found to be alarmingly low. The role of pharmacists is to increase the level of awareness of vaccination for vaccine-preventable diseases and to find ways to reduce the gap between awareness and vaccination.
