The timely Super Science Feats: Medical Breakthroughs series (4 new titles) not only focuses on topics related to COVID-19 but specifically mentions the virus in each installment. Using large images (including historical photos and stock images) and clear, straightforward text, the books introduce a health problem and explain how scientists problem-solved to address it and how the treatment works. Vaccines spotlights early vaccines used to treat smallpox and how today's vaccines work. Written before the roll out of COVID vaccines, this title mentions that they are still being developed. Graphs and labeled images clarify concepts from the text, while short sidebars add interesting facts. Each volume concludes with a hands-on activity that further conveys the book's overall theme. A solid series to help children understand modern health care and practices.
