First, different needle-free supply routes of COVID-19 vaccination could possibly be made available. For instance, there has been a nasal spray developed for childhood flu and oral vaccines developed for rotavirus and for polio. Second, administration of the vaccine by injection could possibly be made extra tolerable, producing optimistic narratives in most of the people of the method. For example, wanting away from the injection could cut back concern (Mithal et al., Reference Mithal, Simmons, Cornelissen, Wong, Riddell, McMurtry and Taddio 2018). Pain mitigation methods (e.g. acute exercise) may be useful (Edwards & Booy, Reference Edwards and Booy 2019). The success of vital COVID-19 vaccination programmes depends on uptake.
