Nature highlights three key infographics from the week in science and research.
Inactivated-virus vaccines against COVID-19 contain SARS-CoV-2 particles that have been chemically treated to make it impossible for them to cause an infection. Stable and relatively easy to manufacture, such vaccines have been distributed widely. Those made by China’s Sinovac and Sinopharm together account for nearly 5 billion of the more than 11 billion COVID-19 vaccine doses delivered globally so far, according to numbers compiled by data-tracking firm Airfinity in London.
that these vaccines provide little to no protection against infection with the rapidly spreading Omicron variant, although they remain crucial for preventing hospitalization and death from COVID-19.An analysis revealed that 97% of palaeontological data come from scientists in high- and upper-middle-income countries. The study involved analysing data from the Paleobiology Database, a widely used repository that contains more than 1.5 million fossil records drawn from nearly 80,000 publications.
More than one-third of these records included authors based in the United States. Other highly-represented countries were Germany, the United Kingdom, France and Canada. The bias in the fossil record towards rich countries could skew researchers’ understanding of the history of life, as our
