Parents' Misperceptions about Chickenpox May Influence Vaccine Decisions
-- Survey Uncovers Motivators and Barriers to Getting Children Vaccinated against Chickenpox --

CHERRY HILL, N.J., Jul 23, 2002 /PRNewswire via COMTEX/ --

Results from a nationwide survey released today found that parents of children aged 4 to 12 were more reluctant to vaccinate their child against chickenpox than against other preventable illnesses and that misperceptions about the seriousness of the disease may be to blame. The new survey of 1,011 parents, conducted by Harris Interactive on behalf of the National Association of Pediatric Nurse Practitioners (NAPNAP) and Merck & Co. Inc., found that although almost all parents surveyed (97%) were aware that a chickenpox vaccine is available, less than two-thirds (64%) had taken action to vaccinate their child. These same parents reported vaccination rates of almost 90% against measles, mumps and rubella and diphtheria, tetanus and pertussis. More concerning, 51% of parents who had a child at risk for developing chickenpox said they were unlikely to vaccinate their child against the disease in the future.

"What we've learned is that in many cases parents are making the decision to not vaccinate based on misperceptions or misinformation. Many of these unvaccinated children between the ages of 4 and 12 may contract the disease later in life," said Tammy Tempfer, MSN, National Association for Pediatric Nurse Practitioners. "Pediatric health experts, including the U.S. Centers for Disease Control and Prevention and NAPNAP, agree that vaccination is the best way to protect against serious complications that may result from chickenpox."

The survey found that several factors act as barriers to vaccinating against chickenpox and that access to information about both the disease and the vaccine was an important motivator for parents who chose to vaccinate.

Misperceptions Create Barriers

According to the survey, among parents of unvaccinated children, 48% were not likely to vaccinate their children because they don't believe that chickenpox is a serious disease. Many parents were not aware that chickenpox can lead to pneumonia, encephalitis, skin infections, scarring or death. Several other facts about chickenpox and vaccination were contradicted by survey findings:

    -- The CDC recommends vaccination against chickenpox as the best way to
       protect against severe complications and death associated with the
       disease; yet, the survey found that 32% of parents thought it was
       better to contract the disease naturally than get the vaccine.
    -- Although it is possible for vaccinated children to develop chickenpox,
       such breakthrough cases are usually milder and are not associated with
       the potentially severe complications of chickenpox found in
       unvaccinated children.  Still, 16% of the parents surveyed were
       concerned that their child may still develop chickenpox after being
    -- Even though there is no clear evidence of waning immunity among people
       who have been vaccinated against chickenpox, about half of
       parents surveyed assumed that the vaccine would wear off.

Among parents surveyed who chose to vaccinate their children for chickenpox, the majority were satisfied with their decision, with 80% reporting they believed they were doing the best thing for their child.

Information is a Key Motivator

The survey findings suggested that health care providers played a key role in parents' decision to vaccinate. Nearly 90% of parents who chose to vaccinate their child for chickenpox reported that their health care provider recommended the chickenpox vaccine. More importantly, 62% of parents said their health care provider's recommendation was the primary factor in deciding to vaccinate. Conversely, 57% of parents who did not vaccinate their child for chickenpox had not discussed the vaccine with their health care provider.

"The survey results show how important it is for parents and health care providers to proactively address vaccination," Tempfer noted.

The chickenpox vaccine is not for everyone. For example, it is contraindicated in persons with a history of hypersensitivity to any component of the vaccine, including gelatin. Parents should talk to their health care provider about whether vaccination is right for their child. As with any vaccine, the chickenpox vaccine does not result in a protective effect in all vaccinees. Adverse reactions that have been reported with the use of the chickenpox vaccine include fever, injection site complaints and rash (injection site and generalized). For a more information about side effects associated with the vaccine, talk to your pediatric health care provider.
