S2b) were made using the expected and upper bound estimates of the VE. Robustness of conclusions to existence of population structure We considered the impact of population structure on the main conclusions of our model. If population structure exists such that people who have high contact rates ...

“How is Australia in the grip of another COVID wave?”— Omicron infections and hospitalisation numbers are rising in Australia as the country prepares for a fourth COVID wave. Professor Nancy Baxter, head of the School of Population and Global Health from the University of Melbourne says ther...
Black (66%) and Hispanic (64%) students were almost twice as likely as White (34%) students to be learning fully remotely, and were also twice as likely as White students who were also remote to have no live access to a teacher.311 UNICEF estimates that a third of the world's school...
During the 3-year period encompassing the COVID-19 pandemic, the population of China lacked exposure to natural infection; therefore, influenza antibodies (either naturally acquired or vaccine-induced) may have decreased or diminished, resulting in an accumulation of susceptible individuals and ...
Firstly, the singular value decomposition method is applied to the ln(𝑚𝑥,𝑡)−𝛼𝑥ln(mx,t)−αx matrix to obtain the estimates of 𝛽𝑥βx and 𝜅𝑡κt. In the second stage, given the 𝛼𝑥αx and 𝛽𝑥βx, the 𝜅𝑡κt parameters are re-estimated. This ...
Ranges reflect the uncertainty around immunity levels and describe population averages. They are not intended to be predictive for any individual. 2 Description of methods for the McKinsey COVID-19 Immunity Index This information, combined with estimates of when infections and vaccinations took place...
Results Target population sizes for covid-19 vaccination vary markedly by vaccination goal and geographical region. Differences in demographic structure, presence of underlying conditions, and number of essential workers lead to highly variable estimates of target populations at regional and country levels...
Using representative data from 31 countries, accounting for a combined population of almost 1.4 billion, we find that in the average country 36 percent of respondents stopped working in the immediate aftermath of the pandemic, 65 percent of households reported decreases in income, and 30 percent ...
