COVID-19 vaccine acceptance and COVID-19-induced income disruption among migrant workers in Saudi Arabia

Background: Neither COVID-19 vaccine acceptance nor income changes among migrant workers during the pandemic has been assessed in Saudi Arabia. Aims: To assess the correlates of willingness to take the COVID-19 vaccine and a decrease in income during the pandemic among migrant workers in Saudi Arabia. Methods: An electronic questionnaire was administered to 2403 migrant workers from the Middle East and South Asia employed in agriculture, auto repair, construction, food service (restaurants), municipality, and poultry farms in Al-Qassim Province, Saudi Arabia. The interviews were conducted in the native languages of the workers in 2021. Chi-square was used to assess the associations, and a multiple logistic regression was used to generate the odds ratio. Data analysis was conducted using SPSS version 27. Results: South Asian workers were 2.30 [95% confidence interval (CI): 1.60–3.32] times more likely to accept the COVID-19 vaccine than those from the Middle East (reference group). Restaurant, agriculture and poultry workers were respectively 2.36 (95% CI: 1.41–3.95), 2.13 (95% CI: 1.29–3.51) and 14.56 (95% CI: 5.64–37.59) times more likely to accept the vaccine than construction workers (reference group). Older (≥ 56 years, reference group ≤ 25 years) workers were 2.23 (95% CI: 0.99–5.03) times, auto repair 6.75 (95% CI: 4.33–10.53) times, and restaurant workers 4.04 (95% CI: 2.61–6.25) times more likely to experience a reduction in income than construction workers. Conclusions: Workers from South Asia were more likely to accept the COVID-19 vaccine and less likely to experience an income reduction than those from the Middle East.

Ballodiolic Acid A and B: Two New ROS, (•OH), (ONOO-) Scavenging and Potent Antimicrobial Constituents Isolated from Ballota pseudodictamnus (L.) Benth.

Bioassays guided phytochemical investigations on the ethyl acetate-soluble fraction of the root material of Ballota pseudodictamnus (L.) Benth. led to the isolation of two new compounds, ballodiolic acid A (1) and ballodiolic acid B (2), along with three known compounds ballodiolic acid (3), ballotenic acid (4), and ß-amyrin (5), which were also isolated for the first time from this species by using multiple chromatographic techniques. The structures of the compounds (1-5) were determined by modern spectroscopic analysis including 1D and 2D NMR techniques and chemical studies. In three separate experiments, the isolated compounds (1-5) demonstrated potent antioxidant scavenging activity, with IC50 values ranging from 07.22-34.10 µM in the hydroxyl radical (•OH) inhibitory activity test, 58.10-148.55 µM in the total ROS (reactive oxygen species) inhibitory activity test, and 6.23-69.01 µM in the peroxynitrite (ONOO-) scavenging activity test. With IC50 values of (07.22 ± 0.03, 58.10 ± 0.07, 6.23 ± 0.04 µM) for •OH, total ROS, and scavenge ONOO-, respectively, ballodiolic acid B (2) showed the highest scavenging ability. Antibacterial and antifungal behaviors were also exposed to the pure compounds 1-5. In contrast to compounds 4 and 5, compounds 1-3 were active against all bacterial strains studied, with a good zone of inhibition proving these as a potent antibacterial agent. Similarly, compared to compounds 3-5, compounds 1 and 2 with a 47 percent and 45 percent respective inhibition zone were found to be more active against tested fungal strains.
