Unpacking COVID-19 Vaccine Attitudes: Exploring Hesitancy and Acceptance Among Undergraduate Students in Bangladesh

BACKGROUND

Vaccine hesitancy is a significant global health concern, and mass vaccination is essential in preventing the spread of COVID-19. Undergraduate students need to be prioritized for vaccination as they continue their academic curriculum physically. However, limited research explores vaccine hesitancy and acceptance among undergraduate students in Bangladesh. Therefore, this study evaluated vaccine hesitancy and acceptance among this population.

METHOD

A web-based cross-sectional study was conducted between May and June 2021 using a structured questionnaire to assess COVID-19 vaccine hesitancy and acceptance among undergraduate students in Bangladesh. The Oxford Covid-19 Vaccine Hesitancy Scale was used to measure vaccine hesitancy. The study used convenient sampling.

RESULT

Across the country, 334 undergraduate students participated in this study on COVID-19 vaccine acceptance, with a mean age of 22.4 years. Most participants were male and unmarried, most having spent four years at university. 89.52% of participants would accept a COVID-19 vaccine if it were suggested by educational institutions or available, while 4.49% refused to receive the COVID-19 vaccine. Participants showed low levels of vaccine hesitancy, with a mean score of 10.77 on the Oxford COVID-19 Vaccine Hesitancy Scale. Most participants had a positive attitude towards receiving the vaccine, with the majority wanting to get it as soon as it becomes available. No association was found between vaccine acceptance and participants' background characteristics.

CONCLUSION

Our study found a high level of vaccine acceptance among undergraduate students in Bangladesh, indicating that this group can be vaccinated quickly, significantly accelerating vaccination goals. However, further large-scale studies are recommended among vulnerable groups, including school and college students, to ensure vaccine preparedness.

In-vitro antibacterial and antioxidant potential of winged prickly ash, green tea and thyme

Herbs and plants are mostly used as antimicrobials and antioxidants owing to the harmfulness and linked side-effects of synthetic chemical constituents. Plants and spices produce various metabolites with antibacterial and antioxidant potential. These metabolites are principally revealed as encouraging healing components or mediators which control ailments in human beings. The present study was aimed to characterize the extracts from selected medicinal plants through in-vitro activities. Winged prickly ash, green tea and thyme were selected and extracted through ethanol and methanol solutions. The extracts were assessed for antibacterial and antioxidant activities. The antibacterial potential of extracts showed the significant extent of the activity against Bacillus subtilis and E. coli. The maximum activity was noted in 80% methanolic fraction of Thymus vulgaris (15.20±0.64 mm) against Bacillus subtilis. Antioxidant potential exhibited the highest phenolic and flavonoid content in Camellia sinensis . The total phenolic content was significantly higher (1456.26±12.05 mg gallic acid) in 80% ethanolic fraction of Camellia sinensis. The flavonoid content in different plant extracts ranged from 8.17±2.02 to 376.29±7.11 mg/g. The radical scavenging DPPH assay also showed the significant antioxidant capacity of selected plants with the methanolic (50%) extract of Camellia sinensis found to be the most potent (78.95±7.12%). It was concluded that the alcoholic extracts of selected medicinal plants revealed the effective antibacterial and antioxidant activity, showing protective prospective against oxidative injury.

Patent ductus arteriosus device embolization

Nonsurgical closure of patent ductus arteriosus (PDA) using a duct occluder placed percutaneously is currently the first line of therapy and the success rate is quite high. Several devices are currently available. An eight year child underwent device closure of the ductus. However after deployment of the device it, became dislodged into the left pulmonary artery. Several attempts at catheter retrieval failed. The child underwent successful surgical removal of the device without cardiopulmonary bypass.
