Copeland was particularly agitated about the Hepatitis B shot.
"In an infant? That's crazy! That is a shot for sexually transmitted disease!" he said.
:We need to be a whole lot more serious about this and aware, and you don't take the word of the guy who’s trying to give you the shot about what’s good and what isn't."
Dr. Don Colbert, a "divine health" expert who has appeared with Copeland in several broadcasts, then said that the autism rate among children had increased along with the number of childhood vaccinations.
"I have had so many patients bring their children in and they say, you know what, the week after I had that immunization, for MMR -- measles, mumps and rubella -- my child stopped talking, my child stopped giving me eye contact. He was not alert, he was not coherent. he quit speaking, he quit being the child I had," Colbert said on the webcast.
Colbert and the Copeland family are wrong about immunizations, said Dr. William Schaffner, a professor of preventive medicine and infectious diseases at Vanderbilt University.
"It's painful because these pastors are trusted spiritual leaders who are speaking to people not only in their congregations but also on television," he said. "They are putting people at risk.”
There is no link between vaccinations and autism, and hepatitis can be passed from mother to child, making the shot necessary and effective, Schaffner said.
Schaffner said that doctors call concerns about bundling immunizations the "pin cushion effect." It's a common but unfounded fear, he said.
Most health experts, including the American Pediatric Association and the Tarrant County Public Health Department, agree with Schaffner.
Neither Eagle Mountain International Church nor Kenneth Copeland Ministries responded to repeated requests for comment.
In a joint statement on Wednesday, the church and ministry said that they believe in, and advocate the use of, medical professionals.
"If an individual is faced with a situation that requires medical attention, that person should seek out the appropriate medical professional and follow their instructions using wisdom," the statement said.
After the measles outbreak, Copeland said that he "inquired of the Lord as to what he would say regarding these vaccinations," according to a statement posted on the church's website on Aug. 15.
The pastor said that God told him to "pray over it," and then to "take advantage of what I have provided for you in Jesus’ name."
When Copeland changes his mind, it's after he has claimed to receive a new divine revelation, said former members of the church.
"Kenneth would always come up with a new prophecy to match what's going on," said one former church member, who wished to remain anonymous in order to maintain business ties with the church.
In this case, Copeland's new revelation -- and the church's recent statements -- represent a big change in church policy, said the former members.
Arden attended and worked at the church, including in its nursery, for six years, first as a volunteer, then as paid staff from 2000 to 2003.
The 35-year-old said she was taught by a supervisor at the nursery, and taught others, how to opt out of a Texas law that requires schoolchildren to be immunized.
Arden said she now deeply regrets those lessons, but she and another former church employee described a closed spiritual world in which doubts are kept quiet and leaders' words are rarely questioned.
"This was Kenneth Copeland’s ministry, and we did nothing that he did not approve of," Arden said. "It's hard to believe that hundreds of his children in his church were not getting vaccinated and he didn't know about it. If he was pro-vaccination, we would have vaccinated our children."
Arden recalled a 2002 lecture to church employees in which they were told that every part of Eagle Mountain International Church and Kenneth Copeland ministries must reflect the founder's vision.
Arden said she was fired from Kenneth Copeland Ministries in 2003 for disagreeing with the church's willingness to take donations from the mentally ill, including institutionalized patients.
She later cooperated with a U.S. Senate investigation into Copeland's and other prosperity preachers' finances. The church was not penalized, but Sen. Chuck Grassley's 2011 report raised questions about the pastors' use of church-owned luxury items like private jets. The Copelands and Eagle Mountain called the investigation an attack on Word of Faith pastors.
