He said it’s “unquestionable” the rise in people infected with whooping cough is connected to more people not getting vaccinated. he also said officials at the federal Centers for Disease Control and Prevention and state public health officials do not see the jump in a vaccine-preventable disease as a coincidence.

In the last 15 years, there’s been widespread publicity about reports allegedly linking vaccinations to autism, but experts haven’t found any scientific basis to support those claims.

Recently, the British Medical Journal concluded that the 1998 study that originally linked the measles, mumps and rubella (MMR) vaccination to autism was an elaborate fraud. still, parents’ fear about immunization persists after watching shows such as “Oprah,” which featured actress Jenny McCarthy alleging there’s a connection between vaccines and autism.

In past years, Dr. Cheryl Wickham didn’t see whooping cough cases ? and when she did, it was “unusual.”

Wickman has been practicing medicine for more than 25 years and works at Saint Joseph Mercy Primary Pediatrics in Howell.

In the last 18 months, Wickham said she has seen an increase in patients who have been diagnosed with whooping cough. Patients diagnosed with the disease include toddlers, older elementary students and three high school students.

She said most patients diagnosed with the disease have received their immunization, but the problem is the immunization wears off. a key benefit of immunization is preventing patients from getting severe symptoms.

Wickham said she’s been pushing for young parents to receive immunizations to prevent them from getting the disease and possibly passing it to a child. while infants are supposed to get three pertussis immunizations before turning 1, she said they are vulnerable before they get their three shots.

As a pediatrician, Wickham said she’s a strong supporter of vaccinations and has a lot of conversations with parents if they might be concerned about the immunizations.

“There’s a lot of information out there on the Internet and media, and it may be alarming, but it’s not necessarily scientifically valid,” she said.

During her 25 years, Wickham has seen controversies come and go over immunizations. in the late 1970s, she recalled the scare that the DTP vaccine (for diphtheria, tetanus and pertussis) caused sudden infant death syndrome, but was later proven unfounded.

She said parents “want to do the best thing for their children, they want to protect them.”

Lawrenchuk said Livingston County has well-informed and highly educated residents who want to know what the facts are. he said he understands why residents would be searching the Internet to get the latest information, but he recommended they talk to their doctors and other health-care providers.

“We want people to make wise, intelligent decisions,” he said. “The facts show the benefits (of immunization) far outweigh the risk.”
