Comparison of in-vial exhaust method versus conventional exhaust method in the injection of COVID-19 vaccine

Objective: The objective of the study was to compare the application effects of in-vial exhaust method and conventional exhaust method in the process of coronavirus disease 2019 vaccine injection. Materials and Methods: Using convenient sampling method, 102 vaccines were selected as experiment group during the process of vaccine injection, and the in-vial exhaust method was used. One hundred and five vaccines were selected as the control group and the conventional exhaust method was adopted. The incidence of vaccine solution spillage and exhausting time in the two groups during exhaust were observed. Results: The incidence of solution spillage in the experiment group was lower than that in the control group (0 vs. 6.67%, P < 0.05). The exhausting time of the experiment group was shorter than that of the control group ([15.12 ± 4.43] s vs. [22.74 ± 6.53] s, P < 0.05). Conclusion: Implementing the in-vial exhaust method in the vaccine injection can effectively reduce the incidence of solution spillage, reduce nucleic acid contamination, and ensure that the vaccine is injected at the prescribed dose. Moreover, the operation is simple and easy, which improves the nurse's vaccination efficiency, and has a higher promotion and application value.
