| Issue/Objective |
COVID-19 booster vaccinations are effective in reducing the transmission and morbidity from the disease among older adults. Vaccine mandates were not commonly implemented for the booster doses unlike the primary series vaccines. There is limited evidence on the uptake of the booster doses among older adults. Therefore, the objective of this study was to identify factors associated with the uptake of the COVID-19 booster vaccines among older adults. The scoping review was guided by the question - What factors are associated with the uptake of COVID-19 vaccine booster dose among older adults?
|
| Methodology/Approach |
A literature search was performed using key words in OVID MEDLINE, EMBASE, PsycINFO and Global Health databases in May 2023. Studies using observational or experimental designs, carried out anywhere in the world and which had older adults as a sub-population of interest were included. Title and abstract as well as full text screening was conducted using set criteria. A critical appraisal of the articles was conducted Only studies rated as being of moderate to high quality were included in the final review. |
| Results |
Thirteen journal articles were identified. Demographic, vaccine-related, health- related and social factors were identified as affecting COVID-19 vaccine booster uptake among older adults. Within these themes, perceived susceptibility and efficacy of vaccines and availability of social supports were important factors affecting uptake. There was conflicting evidence within themes on how the factors served as enablers or barriers to booster uptake. |
| Discussion/Conclusion |
The review has highlighted modifiable factors for which targeted interventions may be designed to improve booster uptake. Further studies are required to generate more robust evidence. |
