| Officials say AstraZeneca released outdated data, the European Commission curbs vaccine exports, and a federal survey highlights inequity in pandemic schooling. Here's what you should know: Headlines Officials voice concern that AstraZeneca released preliminary results based on outdated information On Monday, AstraZeneca released promising preliminary data from its Phase III vaccine trial in the US. But shortly thereafter, health officials voiced concern that the efficacy data was based on outdated and incomplete information. Early Tuesday morning, the National Institute of Allergy and Infectious Diseases put out a statement encouraging AstraZeneca to work with the data safety and monitoring board auditing the trial to provide accurate, up-to-date numbers as soon as possible. Notably, the NIAID statement only addressed efficacy data, and not safety, which Monday's results indicated was not a concern. European Commission plans to limit Covid-19 vaccine exports Earlier today the European Commission debuted a new plan that will limit Covid-19 vaccine exports from the region for the next six weeks as cases rise yet again. This new legislation comes on the heels of the EU's disputes with AstraZeneca, which reduced its supply this winter due to production issues, but could also affect exports of Pfizer and Moderna shots. It is expected to be enacted tomorrow and is likely to impact vaccine supply to Britain and potentially Canada and Israel, but not the US, whose supply is manufactured primarily within the country. Federal survey examines school reopenings and highlights racial disparities in education A new survey from the National Center for Education Statistics offers a first look at how much in-person instruction students are getting, and which students are getting it. Biden has said that he wants a majority of K-8 schools open for full-time, in-person classes by the end of April, and the data shows he's likely to meet that goal. But it also underscores the many ways this pandemic has disrupted education, especially along lines of race. Around half of white students surveyed were in full-time, in-person school in January, but only 28 percent of Black students and 33 percent of Hispanic students could say the same.

Illustrators might consult with several researchers, read up on the scientific literature, and examine databases of protein structures before putting pen to paper.
