Why do these vaccines not harm us?
Answers
Answer:
The world greets newborn babies by bombarding them with everything from dust to disease-causing microbes. Babies can deftly parry exposures to certain harmful substances, thanks to antibodies passed onto them in the womb. But this kind of inherited immunity is short-lived, so a child must develop her own immune system response to combat life-threatening diseases. That's where vaccines come into the picture. By age two, most children will receive almost 30 shots designed to boost a child's natural defenses against disease. Yet at the same time, parents who take their children for those recommended vaccinations might be inundated with Web site and celebrity-espoused rumors making false claims that shots are not necessary or cause autism.
