| Abstract |
Neonatal vaccination against hepatitis B virus (HBV) infection was launched in 1998 in Turkey. The aim was to evaluate the persistence of seroprotection after HBV vaccination in order to determine the necessity of a single booster dose in 2- to 12-year-old children. This study was conducted retrospectively using hospital records of the children aged 2-12 years old who attended the pediatric outpatient clinics of Diskapi Training and Research Hospital, Ankara, Turkey between January 2010 and June 2011. Children who had received three doses of HBV vaccination in their infancy were included. A total of 530 children enrolled into the study, and 352 (66.4 %) of them had protective antibody to hepatitis surface antigens (anti-HBs) titer greater than 10 mIU/ml. The proportions of children with low, intermediate, and high anti-HB titers are different for those under 3 years of age. The majority were in the intermediate category. Those aged 4-10 years and 11 or older represented two-thirds of the children with high titers (p = 0.000). None of the children had chronic HBV infection. Unprotected children responded well after receiving the booster dose. The mean anti-HB concentration after the booster dose was more than 200 times higher than the mean antibody concentration before (p < 0.001). Conclusion: Our data suggest that HBV vaccination may confer long-term immunity. Use of routine booster doses of vaccine at these ages does not appear necessary to maintain long-term protection in successfully vaccinated immunocompetent children in the region. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 June 2013.
All research outputs
#18,314,922
of 22,678,224 outputs
Outputs from European Journal of Pediatrics
#3,082
of 3,666 outputs
Outputs of similar age
#114,730
of 149,517 outputs
Outputs of similar age from European Journal of Pediatrics
#16
of 28 outputs
Altmetric has tracked 22,678,224 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,666 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 7th percentile – i.e., 7% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 149,517 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 28 others from the same source and published within six weeks on either side of this one. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
