Gruesome attacks against Indian targets?frequently suicidal?have been a regular feature of the Kashmir imbroglio for the past decade...
...similar strategy could lead to vaccines against malaria and TB. But while conquering such hitherto vaccine-resistant diseases would be dramatic, it would be positively revolutionary to extend vaccines to illnesses that have seemed beyond their reach. One such candidate is heart disease--which may involve the immune system in ways nobody ever imagined just a few years ago.
