A study has found that the older version of the pertussis vaccine was more effective than the current one. The previous vaccine was phased out due to more side effects such as high fever:
Teenagers who received four shots with the older vaccine -- called whole-cell vaccine -- before they were 2 years old were significantly less likely to become infected with whooping cough during a recent outbreak in California, compared to children who received all of their immunizations with the new vaccines, called the acellular vaccine.
"Teens who were vaccinated with the acellular vaccine appear to have a six times higher risk of [whooping cough] than teens who received four doses of the whole-cell vaccine. And, the teens who received some whole-cell vaccine and some acellular had about a four times higher risk than teens who received all whole-cell vaccines," said the study's lead author, Dr. Nicola Klein, co-director of the Northern California Kaiser Permanente Vaccine Study Center, in Oakland.
Do you think they need to use a better whooping cough vaccine, even at the risk of more side effects?
