Dear Reader,

Last week the U.S. Food and Drug Administration followed the advice of an advisory panel and authorized the Pfizer and Moderna vaccines for kids aged six months through four or five years, respectively. The decision was a long time coming for this age group, which has had to wait the longest for access to the vaccines. I wrote about the safety and efficacy of the vaccines, the risks to children from COVID, and what the news means to parents of young kids.

Hacking the Immune System

The immune system is a marvel, but sometimes those defenses need help. In this eBook, we examine various ways the immune system is being manipulated to fight disease, starting with the science behind the research into COVID vaccines and treatments. We also examine cutting-edge interventions for infectious diseases beyond COVID such as a universal flu vaccine, immunotherapies for cancer and more.

QUOTE OF THE DAY

"Not only are you protecting against the rare chance that your child would have severe disease [by vaccinating them], you're also helping them achieve the normality in life that we've all been seeking--to keep all your current activities ongoing without interruptions."

Sallie Permar, chair of pediatrics at Weill Cornell Medicine and pediatrician-in-chief at New York–Presbyterian Komansky Children's Hospital, in Scientific American
