Panel description:

Can a flu shot make you sick? How does the HPV vaccine work? What’s the prognosis for an AIDS vaccine in the next decade? These are some of the vaccine-related questions health writers face routinely, as more vaccines have come on the market in recent years to prevent problems ranging from cervical cancer to swine flu. This panel looks at the growth in available vaccines and an overview of how they work. It also examines nettlesome questions about why some vaccines are so hard to manufacture and why many people remain afraid of them.
