The American researchers concluded that the children vaccinated against varicella (chickenpox) are not just protected from this disease but also have a lower risk to get infected with shingles as compared with unvaccinated children. The study was published in the Journal of Pediatrics.
The scientists from Kaiser Permanente Center for Health Research have processed the data of more than 6 million children aged under 17 and younger starting from 2003 till 2014.
About 50% of the children were vaccinated within the part or the entire period of research. The shingles incidence rate was 78% lower than among vaccinated children as compared with unvaccinated. The frequency of shingles has reduced by 72% since the number of vaccinated children has increased.
