Expected cost effectiveness of the fourth dose of COVID-19 vaccine against the omicron variant of COVID-19: a preliminary report

ABSTRACT

Objectives: COVID-19 immunization has been shown to be effective in the prevention of COVID-19. Traditionally, two doses of COVID-19 vaccines are required. Booster immunization is generally required when immunity has deteriorated. Methods: The effectiveness of the alternate boost immunization protocol is still unknown. The authors of this study used a cost-effectiveness analysis, which is a retrospective analysis on datasets on cost and effectiveness, to examine the projected cost-effectiveness of boosting COVID-19 vaccination by a fourth dose. Results: The cost-effectiveness of the fourth-dose COVID booster vaccine was found to be higher in this study. Conclusion: It could imply that vaccinating against the current pandemic of the novel form, omicron, with the additional COVID-19 vaccine is a smarter idea.
