Background: Several vaccines have been developed and administered since coronavirus disease 2019 (COVID-19) was declared a pandemic in March 2020. In April 2021, the authorities in Zambia administered the first doses of the Oxford-AstraZeneca® COVID-19 vaccine. However, little is known about the awareness and acceptability of the vaccines among the Zambian population. This study was undertaken to address this starting with undergraduate pharmacy students in Zambia. Materials and methods: A descriptive cross-sectional survey was conducted among 326 undergraduate pharmacy students in Zambia using an online semi-structured questionnaire from 12th to 25th April 2021 and analysed using Stata version 16. Test of associations were undertaken using Pearson chi-square test or Fisher's exact test as appropriate. The multivariable logistic regression was used to investigate the determinants of awareness and acceptability. All statistical tests were performed at a 5% significance level and 95% confidence level. Results: Among 326 participants, 98.8% were aware of the COVID-19 vaccination programme but only 24.5% would accept the vaccine should it be made available to them. Awareness of the COVID-19 vaccine was influenced by religious beliefs (aOR=0.01, 95% CI: 0.01 to 0.20, p=0.004). Being male (aOR=1.78, 95% CI: 1.05 to 3.02, p=0.034) and single (aOR=2.61, 95% CI: 1.04 to 6.55, p=0.041) was associated with higher odds of accepting the vaccine. Being unemployed (aOR=0.31, 95% CI: 0.15 to 0.66, p=0.002) was associated with lower odds of vaccine acceptancy. Barriers to acceptance of the vaccine were possible side effects (78.5%) and scepticism about its effectiveness to prevent COVID-19 (10.2%). Conclusion: There was significant vaccine hesitancy towards COVID-19 vaccines among Zambian pharmacy students despite their awareness about the vaccines. Health authorities must work collaboratively with the Universities and other institutions to mitigate vaccine hesitancy, especially with pharmacy students a key part of the future healthcare workforce overseeing disease prevention strategies. These findings can help guide future interventions to address vaccine hesitancy to reduce future transmission rates of this virus.
