Dennis Drew was prepared to fight the enemy in Iraq, but never got the chance. After his military vaccinations, his immune system completely unraveled.
"Severe pneumonia and myocarditis, I think almost killed me," said Drew, a U.S. Army chemical weapons specialist.
Now living in constant pain, daily life is almost unbearable. His illnesses are nearly identical to those suffered by Rachel Lacy before she died last spring. The coroner said her military shots were likely to blame.
It's estimated thousands of soldiers claim serious illnesses from military vaccines.
