Teen vaccination rates on the rise

More American adolescents are receiving recommended vaccinations, according to a new study by the U.S. Centers for Disease Control and Prevention.

The new findings have come after a recent report that vaccinations for toddlers are also on the rise, suggesting that public concerns over the safety of vaccines may be lowering, according to

"I think that is very good news," Dr. Samir S. Shah, an associate professor of pediatrics at the University of Cincinnati College of Medicine, said, reports. Shah was not involved in either survey.

Dr. Shah said the change may be related to renewed efforts on the part of public health agencies to promote vaccines and explain their risks and benefits.

Shots can cause swelling and soreness at the point where they are injected, but serious reactions are very rare at less than one out of every million, according to experts.

In late August, the Institute of Medicine released a study that found no link between the use of vaccines and autism.

"Parents are also becoming involved and participating in helping debunk some of the myths surrounding vaccines," Shah said, Reuters reports.

The new CDC study is based on the immunization records of 20,000 teenagers who agreed to let their doctors share their information with researchers.

The surveys showed that DTaP vaccinations against diphtheria, tetanus and whooping cough were up from 34 percent among those born in 1991 and 68 percent among those born in 1996. Meningococcal vaccinations climbed from eight percent to 50 percent for children born in 1993 and 1996.
