CAMP LEJEUNE, N.C. A Marine helicopter pilot from who refused on religious grounds to receive an anthrax vaccination was dismissed from the Corps and ordered to serve seven months in prison. 1st Lt. Erick Enz, 32, of Vancouver, Wash., pleaded guilty during a court-martial Tuesday to disobeying the order of a superior. He faced a maximum punishment of five years confinement, forfeiture of all pay and allowances and dismissal from service. Enz, a CH-46 Sea Knight pilot, could serve as little as 30 days based on a pretrial agreement. Enz, a father of five and Bible study group leader, said he prayed for guidance before researching the potential adverse affects of the vaccination and refusing inoculation. Military Judge Col. Steven Day ruled in an earlier motion that Enzs objection on religious grounds would not be allowed as evidence. Department of Defense officials contend that the vaccination is safe, as do military doctors at Camp Lejeune Naval Hospital. A September 2002 U.S. General Accounting Office survey of 1,253 soldiers who received the anthrax vaccination found that 84 percent suffered minor reactions. At least 24 percent had major multiple systemic reactions, the latter more than 100 times higher than the estimate of the manufacturer. Enz is a veteran of Operation Desert Storm. Superiors and peers described him as a natural leader who was well-liked and respected. The people who refuse this are not the dummies or the troublemakers, said former Air Force F-16 pilot retired Lt. Col. John Richardson of Raleigh, a critic of the vaccine. I get two to three unsolicited calls or e-mails a week sometimes as many as five a day from kids who are sick. Someone has to stand up and do the right thing.
