( Koskan et al, 2019 , Ryan et al, 2020 ) And virtually all the intervention studies indicated the more rigorous study designs, much larger studies, and much longer follow-up periods are needed to more fully understand the efficacy interventions designed to improve vaccine delivery and that these should include improved communication among stakeholders, including between primary care providers and pharmacists ( Hohmeier et al, 2016 , Calo et al, 2019 , Islam et al, 2017 , Doucette et al, 2019 , Islam et al, 2019 , Koskan et al, 2019 , Lutz et al, 2018 , Ryan et al, 2020 , Skiles et al, 2011 , Ko et al, 2014 , Shah et al, 2018 , Shah et al, 2018 , Shah et al, 2018 , Cebollero et al, 2020 ) and sustainable interventions ( Cebollero et al, 2020 ) that will continue after the intervention period is over.…”
