Vaccines are biological substances that cause the human immune system to build up its defenses against specific diseases. Public health officials recommend a series of vaccines for all children, as well as some vaccines for teenagers and adults. But not everyone gets the vaccines they need. Many poor nations don't have the resources to deliver vaccines to every community. Some parents refuse to have their children vaccinated because they don't believe the evidence proving that vaccines are safe.
The effort to wipe out diseases using vaccines continues. Vaccine Investigation recounts the fascinating history of vaccines, their important role in protecting community health, and the excitement of cutting-edge research.
Описание: In the era of questionable Internet "facts" and parental oversharing, it's more important than ever to find credible information on everything from prenatal vitamins to screen time. The good news is that parents and parents-to-be no longer need to rely on an opinionated mother-in-law about whether it's OK to eat sushi in your third trimester, an old college roommate for sleep-training "rules," or an online parenting group about how long you should breastfeed (there's a vehement group for every opinion). Credible scientific studies are out there-and they're "bottom-lined" in this book. The ultimate resource for today's science-minded generation, The Informed Parent was written for those who prefer facts to "friendly advice," and who prefer to make up their own minds, based on the latest findings as well as their own personal preferences. Science writers and parents themselves, authors Tara Haelle and Emily Willingham have sifted through thousands of research studies on dozens of essential topics, and distill them in this essential and engaging book.
