Peking University Researcher Details New Studies and Findings in the Area of COVID-19 (COVID-19 Vaccination Coverage among 42,565 Adults Amid the Spread of Omicron Variant in Beijing, China): Coronavirus – COVID-19

2023 APR 10 (NewsRx) -- By a News Reporter-Staff News Editor at Vaccine Daily -- Investigators publish new report on COVID-19. According to news originating from Beijing, People’s Republic of China, by NewsRx correspondents, research stated, “Vaccines against coronavirus disease 2019 (COVID-19) have been in use for over two years, but studies that reflect real-world vaccination coverage and demographic determinants are lacking. Using a multistage stratified random cluster sampling method, we planned to directly explore vaccination coverage and the demographic determinants of different doses of COVID-19 vaccines in Beijing, especially in older populations.”

Financial supporters for this research include National Natural Science Foundation of China; Beijing Natural Science Foundation-haidian Original Innovation Joint Foundation; Beijing High-level Public Health Technical Personnel Training Program.

The news journalists obtained a quote from the research from Peking University: “All 348 community health service centers in 16 districts were involved. We performed multivariable logistic regression analyses to identify demographic determinants of different coverage rates via adjusted odds ratios (aORs) and 95% CIs. Of the 42,565 eligible participants, the total vaccination coverage rates for 1 dose, 2 doses, 3 doses, and 4 doses were 93.3%, 91.6%, 84.9%, and 13.0%, respectively, but decreased to 88.1%, 85.1%, 76.2%, and 3.8% in the older population. Among all participants, younger (aOR = 1.77, 95% CI: 1.60-1.95), male (aOR = 1.15, 95% CI: 1.06-1.23), and better-educated residents (high school and technical secondary school aOR = 1.58, 95% CI: 1.43-1.74; bachelor’s degree aOR = 1.53, 95% CI: 1.37-1.70) were more likely to be fully vaccinated. People who lived in rural areas (aOR = 1.45, 95% CI: 1.31-1.60) and held the new rural cooperative health insurance (aOR = 1.37, 95% CI: 1.20-1.57) established a higher rate of full vaccination coverage. No history of chronic disease was positively associated with a higher coverage rate (aOR = 1.81, 95% CI: 1.66-1.97). Occupation also affected vaccination coverage. Demographic factors influencing the rate of vaccination with at least one or three doses were consistent with the results above.”

According to the news reporters, the research concluded: “Results remained robust in a sensitivity analysis. Given the highly transmissible variants and declining antibody titers, accelerating the promotion of booster vaccination coverage, especially in high-risk groups such as the elderly, is a top priority. For all vaccine-preventable diseases, rapidly clarifying vaccine-hesitant populations, clearing barriers, and establishing a better immune barrier can effectively safeguard people’s lives and property and coordinate economic development with epidemic prevention and control.”
