Purpose of Study

The Centers for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization Practices (ACIP) recommend that adolescents routinely receive Tdap, MCV4, and HPV vaccinations at 11 to 12 years of age1. Beginning in the 2014-2015 school year, Tdap and MCV4 were added to the list of required vaccines for Georgia students entering seventh grade who were born on or after January 1, 2002. This report summarizes the annual assessment of immunization coverage for school-required vaccinations as well as one -dose and complete dose coverage of HPV among seventh grade students in Georgia's 18 Public Health Districts. HPV coverage was assessed using the 2016 ACIP recommendations of a 2 or 3-dose schedule based on the age of the recipient2.

Study Design
The annual Georgia Adolescent Immunization Study (GAIS) employs a cross-sectional research design to ascertain the vaccine coverage rate for 7th grade children in the State of Georgia. Immunization history data for 7th grade students from 18 Health Districts were analyzed to calculate these rates. Identifying information and immunization history data were obtained from school 3231 files and the Georgia Registry of Immunization Transactions and Services (GRITS). Immunization rates for Tdap, Polio, MMR, MCV4 (meningococcal), Hepatitis B, Varicella and HPV vaccines were calculated.
Data collection for the 2017 GAIS study began February 1, 2017 and lasted for three months. A two-stage clustersampling scheme was developed to randomly select the study sample. Stage one of the cluster sampling scheme involved randomly selecting up to 30 middle schools from each of the 18 Health Districts. The number of schools sampled from each district was determined using the following factors:
target population size per district estimated percent response rate estimate design effect confidence interval width
If a District had fewer than 30 schools, then all schools in that District were sampled.
Stage two of the sampling scheme involved randomly selecting an established number of students from each school. This number varied by District depending on the number of schools sampled and population. Basic coverage rates were then calculated for each of the specific vaccines of interest.
Target and Sample Populations
The target population of the 2017 GAIS included all 7th grade children in the State of Georgia during the 20162017 school year. A sample of 6,191 seventh grade students, attending both private and public Georgia schools, were selected for the study. The sample design allowed for independent estimates to be calculated for each of the 18 Health Districts in the State.

Data Collection
An electronic web-based data collection system named "GAIS" was created to systematically collect the required information for each child. This system interfaces with GRITS to extract immunization data for students enrolled in the study.
Data collection was carried out by the State's Immunization Regional Consultants (IRCs), who are responsible for 13 health regions of the state which may overlap Health District boundaries. The IRCs participated in training at the start of the data collection period. A Training Manual was also provided and made available on the GAIS log-in screen.
Data Collection Protocol
Step #1: Obtain student sample
Before the data collection process began, IRCs were assigned a maximum of 30 schools in their respective Districts and assigned a required number of students per school to be sampled. Once at a school, the IRC obtained an alphabetized roster of all current 7th graders attending that school. Using the total number of seventh graders, a random number generator was applied to randomly select the 13 students chosen as the 2017 GAIS sample.
Step #2: Collect immunization forms at public and private schools
Once the IRC selected the school sample, each specific child's 3231 form was located to obtain their immunization history. A comparison of the GRITS record and the 3231 form was conducted for each child to make sure all vaccines received matched between sources. If any dates were missing from either source, steps were taken to update the 3231 form and/or the GRITS record to match. If a 3231 was found to be expired, a new one was printed out from GRITS for the school's record.
Step #3: Input children to data collection website
A record was created by the IRC for each sampled child in the GAIS website. Information collected included first and last name, date of birth, county, school, exemption and waiver status and lab confirmation of immunity. A blank vaccine list was also available in the GAIS record for the IRC to either: 1) add each of the vaccine dates of interest in the table; or, 2) perform a direct upload from GRITS into the GAIS record.
Step #4: Record review
As the records were completed using the web GAIS system, problematic records were reviewed by the Principal Investigator and resolved before data analysis began.

Data Analysis
The data cleaning and analysis for the 2017 GAIS were performed using R (ver. 3.4.2) software.
Immunization data were used to determine what percentage of 7th graders were up-to-date (UTD), which was defined as having at least 3 doses of Hepatitis B, 2 doses of MMR, 2 doses of Varicella, 1 dose of Tdap and 1 dose of MCV4 vaccines. UTD immunization rates as well as individual vaccine coverage rates were assessed at both the State and Health District level. A vaccination was considered valid if it met ACIP's recommendations for dosing and spacing and was given prior to January 1, 2017.
Margins of error are provided for all immunization coverage estimates. The margin of error is a convenient notation of the 95% confidence interval range. For example, 94.4 0.6 represents the confidence interval (93.8, 95.0) for the statewide UTD estimate of 94.4%. Immunization rate differences between comparison groups were tested with R (ver 3.4.2, Epi package), utilizing a 2 sample test for equality of proportions. Significant differences (p<0.05) are bolded and italicized in the appropriate tables. Comparison groups are defined as:
2017 State rates vs individual 2017 District rates Individual District rates for 2016 vs 2017 2017 coverage rates for male vs. female students 2017 coverage rates for students attending public
vs. private schools
Sample Table 1 serves to illustrate these comparisons. For example, in Sample Table 1, the rates for having 1 dose of HPV are significantly different (p<0.05) between :
The State (50.1%) and District X (58.6%) in 2017 Male (52.6%) and female students (65.5%) in
District X in 2017 Similarly, the rates for completing the HPV series are significantly different (p<0.05) between : The State (28.0%) and District X (20.2%) in 2017 2016 (12.4%) and 2017 (20.2%) for District X Students attending public (24.9%) and private
schools (14.2%) in District X in 2017

Limitations
When interpreting the study results, the following limitations of the study should be considered:
1. Compared to other sampling methods, cluster sampling is least representative of the population. Individuals within a cluster tend to have similar characteristics and there is a chance of over- or underrepresentation of the population, leading to skewed results. The two-stage cluster sampling scheme was used because of its low-cost and efficient method of collecting a larger sample size across a wide area.
2. Some IRCs had less than 30 middle schools in their District and were therefore required to sample all middle schools. Larger Districts were restricted to a maximum sample of 30 schools, due to time and resource restraints. This may lead to underrepresentation in Districts that have more than 30 schools. We tried to overcome this limitation by randomly selecting schools with equal probability of selection.

The 2017 Georgia Adolescent Immunization Study (GAIS) sampled 6,191 seventh grade adolescents statewide (Table 1). Of the students sampled, 50.5% were male, 48.6% were female, and 0.9% had missing gender information. Students enrolled in public schools accounted for 71.7% of the sample; 28.3% were enrolled in private schools. A total of 479 schools were sampled (315 public, 164 private).
Adolescents were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. Statewide, the 2017 UTD immunization rate for 7th graders was 94.4%, lower than the 2016 rate (94.7%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 2).
Statewide, the 2017 coverage rates were higher than the 2016 rates except for the UTD rate, which showed a nonsignificant decrease. The statewide rates for Hepatitis B, MMR, Varicella, Polio and HPV (1-dose and series completion) showed a significant increase from 2016. Statewide coverage rates for HPV vaccinations (1-dose or series completion) differed significantly between male and female adolescents. Statewide coverage rates for all vaccines were significantly higher for students enrolled in public schools vs. private schools (Table 2).
Transfer students with incomplete immunization records have a 30-day waiver period to meet immunization requirements. Only ten (0.2%) of the students in the State

Six (0.1%) of the students in the State sample had a medical exemption for one or more vaccines; 135 (2.2%) students had a religious exemption on file (Table 1).
Fourteen adolescents had documentation of serologic immunity in lieu of vaccination: 4 had varicella immunity, 1 had measles, mumps, rubella (MMR) immunity, and 9 had hepatitis B immunity. Thirty-two (32) students had either documentation of physician-diagnosed or a history of varicella (not shown). All of these students were excluded from the respective statewide vaccination rate determinations which were calculated based only on receipt of vaccine.

The 2017 GAIS sampled 370 seventh grade adolescents in District 1-1 (Table 11-A). Of the students sampled, 52.7% were male, 45.9% were female, and 1.4% had missing gender information. Students enrolled in public schools accounted for 84.3% of the sample; 15.7% were enrolled in private schools. A total of 30 schools were sampled (24 public, 6 private).
Adolescent were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. In District 1-1, the 2017 UTD immunization rate for 7th graders was 94.3%, lower than the 2016 rate (96.1%) and higher than the State rate for 2017 (94.1%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 1-1-B).
The 2017 District 1-1 coverage rates for most vaccines varied slightly from the 2016 rates except for HPV completion which showed a significant increase from 9.9% to 21.9%. The UTD coverage rate differed significantly among adolescents who attended public vs. private schools. District 1-1 coverage rates did not differ significantly from overall State rates, or by gender (Table 1-1-B).

The 2017 GAIS sampled 314 seventh grade adolescents in District 1-2 (Table 12-A). Of the students sampled, 51.0% were male, 48.4% were female, and 0.6% had missing gender information. Students enrolled in public schools accounted for 72.0% of the sample; 28.0% were enrolled in private schools. A total of 29 schools were sampled (18 public, 11 private).
Adolescent were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. In District 1-2, the 2017 UTD immunization rate for 7th graders was 92.0%, higher than the 2016 rate (90.5%) and lower than the State rate for 2017 (94.4%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 1-2-B).
The 2017 District 1-2 coverage rates for all vaccines were slightly higher than the 2016 rates except for HPV completion which was significantly higher. The 2017 coverage rates for MMR, Varicella, Tdap, MCV4, Polio and HPV (1-dose) were significantly lower in District 1-2 when compared to the State rates. The 2017 District 1-2 coverage rates did not vary by gender, however, the rates for all vaccines were significantly higher for students enrolled in public vs. private schools (Table 1-2-B).

The 2017 GAIS sampled 323 seventh grade adolescents in District 2-0 (Table 20-A). Of the students sampled, 47.1% were male, 52.3% were female, and 0.6% had missing gender information. Students enrolled in public schools accounted for 72.4% of the sample; 27.6% were enrolled in private schools. A total of 29 schools were sampled (18 public, 11 private).
Adolescent were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. In District 2, the 2017 UTD immunization rate for 7th graders was 92.9%, lower than the 2016 rate (94.8%) and lower than the State rate for 2017 (94.4%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 2-0-B).
The 2017 District 2-0 coverage rates for all vaccines were slightly higher than the 2016 rates except for HPV completion which was significantly higher than the 2016 rate. The 2017 coverage rates for HPV (1-dose and series completion) were significantly lower in District 2-0 when compared to the State rates. The 2017 District 2-0 coverage rates did not vary by gender, however, the rates for Tdap, MCV4, Polio and HPV (1-dose and series completion) were significantly higher for students enrolled in public vs. private schools (Table 2-0-B).

The 2017 GAIS sampled 345 seventh grade adolescents in District 3-5 (Table 35-A). Of the students sampled, 50.1% were male, 48.7% were female, and 1.2% had missing gender information. Students enrolled in public schools accounted for 67.2% of the sample; 32.8% were enrolled in private schools. A total of 30 schools were sampled (18 public, 12 private).
Adolescent were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. In District 3-5, the 2017 UTD immunization rate for 7th graders was 87.2%, lower than the 2016 rate (88.2%) and lower than the State rate for 2017 (94.4%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 3-5-B).
The 2017 District 3-5 coverage rates varied only slightly from the 2016 rates except for HPV series completion which showed a significant increase. Compared to the 2017 State coverage rates, the UTD, Hepatitis B, MMR, Varicella, Tdap, MCV and Polio coverage rates were significantly lower in District 3-5, but the 1-dose HPV was significantly higher. The 2017 District 3-5 coverage rates did not vary by gender, but the rates for UTD, Varicella, Tdap and MCV4 were significantly lower in children attending public vs. private schools (Table 3-5-B).

The 2017 GAIS sampled 329 seventh grade adolescents in District 7-0 (Table 70-A). Of the students sampled, 48.6% were male, 49.8% were female, and 1.5% had missing gender information. Students enrolled in public schools accounted for 79.3% of the sample; 20.7% were enrolled in private schools. A total of 18 schools were sampled (12 public, 6 private).
Adolescent were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. In District 7, the 2017 UTD immunization rate for 7th graders was 94.5%, higher than the 2016 rate (89.6%) and higher than the State rate for 2017 (94.4%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 7-0-B).
The 2017 District 7-0 coverage rates varied only slightly from the 2016 rates except for the UTD and HPV (1-dose and series completion) rates which showed significant increases. Compared to the 2017 State coverage rates, the rates for HPV (1-dose and series completion) were higher in District 7-0. The 2017 District 7-0 coverage rates did not vary by gender, but the rate for 1-dose of HPV was significantly higher in children attending public vs. private schools (Table 7-0-B).

The 2017 GAIS sampled 347 seventh grade adolescents in District 10-0 (Table 10-0-A). Of the students sampled, 50.4% were male, 49.3% were female, and 0.3% had missing gender information. Students enrolled in public schools accounted for 65.1% of the sample; 34.9% were enrolled in private schools. A total of 29 schools were sampled (18 public, 11 private).
Adolescent were considered up-to-date (UTD) if they received 3 Hepatitis B, 2 MMR, 2 Varicella, 1 Tdap and 1 MCV4 vaccines by January 1, 2017. In District 10-0, the 2017 UTD immunization rate for 7th graders was 93.9%, lower than the 2016 rate (95.7%) and lower than the State rate for 2017 (94.4%). Immunization rates that decreased from the previous year are shown in red; rates that were significantly different (p<0.05) between comparison categories are bolded and italicized (Table 10-0-B).
The 2017 District 10-0 coverage rates for all vaccines were similar to the 2016 rates. Similarly, the 2017 District 10-0 coverage rates did not vary by gender. Compared to the 2017 State coverage rates, the rates for HPV (1-dose and series completion) were higher in District 10-0. The coverage rates for MMR and Polio were significantly higher for students attending public vs. private schools in District 10-0 (Table 10-0-B).

Transfer students with incomplete immunization records have a 30-day waiver period to meet immunization requirements. Only two (0.6%) of the students in the District 10-0 sample were found to be in the school waiver period (Table 10-0-A).
One (0.3%) of the students in the District 10-0 sample had a medical exemption for one or more vaccines; 7 (2.0%) students had a religious exemption on file (Table 10-0-A).
