Objectives We evaluated immunisation with Bacille Calmette-Guerin (BCG) among newborns in 983090983088983089983089 in the Maringue DistrictSoala Province Mozambique which includes seven health units Te study was motivated by the act that in official reportsimmunisation coverage was unreliable (more than 983089983088983088) Methods Te office o maternal-child health o the central Maringue-
Sede health unit provided the number o live newborns in 983090983088983089983089 at the maternal clinics o the seven health units and an estimate o the number o home deliveries From vaccination registers we abstracted records o BCG vaccinations administered in the period983088983089983088983089983090983088983089983089ndash983091983088983088983094983090983088983089983090 to children born in 983090983088983089983089 Results Te number o live newborns was 983091983091983093983091 Overall the number o BCG vaccinations administered was 983090983096983097983091 with a coverage o 983096983094983091 Conclusion In this study we could only calculate an approximatecoverage estimate because o unavailability o adequate individual inormation Recording practices should be changed in order toallow use o individual inormation and linkage across different inormation sources and thus a more precise vaccination coverageassessment
1 Introduction
In Mozambique a nationwide immunisation program (Ex-tended Programme o Immunisation EPI in PortuguesePrograma Alargado de Vacinacao PAV) was started in 983089983097983095983097
[983089] Since perormance was poor in 983090983088983088983093 a comprehensiveMulti Year Plan (cMYP) was launched with a view to devisingstrategies in line with the WHOUNICEF Global Immuni-sation Vision and Strategy (GIVS) [983090] with the objective toreach at least 983097983088 national vaccination coverage and at least983096983088 coverage in every district Te current immunisationschedule includes Bacille Calmette-Guerin (BCG) at birthoral polio vaccine (OPV) at birth 983094 983089983088 and 983089983092 weeksDiphtheria Pertussis etanus Hepatitis B (DP-HepB) at 983094983089983088 and 983089983092 weeks measles at 983097 months [983089]
In reports rom the Ministry o Health (983090983088983088983092ndash983090983088983088983096) im-munisation coverage percentages were largely variable acrossyears and sometimes unreliable (gt983089983088983088) [983089] Te reasons or
these anomalous 1047297gures are at least two (983089) Te denominator(ie the number o children lt983089 year so-called ldquogrupo alvordquotarget group) is only presumed In act it is calculated by taking a 1047297xed percentage (983092) o the whole population(almost 983090983091 million people in 983090983088983089983089-983090983088983089983090) [983090] (983090) Te reerence
periods o immunisation and birth data are different thatis part o the immunisation doses administered in a givenyear are given to inants born in the previous year Also theWHO website on Mozambique reports highly variable andunusually high (gt983097983097983093) percentages [983091] Te 983090983088983089983088 estimateswere as ollows BCG983097983088 DP-HepB third dose 983095983092OPVthird dose 983095983091 measles 983095983088 Similarly in the official reportso the Maringue District Soala Province which includesseven health units (Unidade de Saude US) (Figure 983089) BCGcoverage in 983090983088983089983089 was clearly unreliable (983089983088983096983094) Te reasonsare the same seen previously or the national coverage In thedistrict the target group is estimated as 983092times 983096983092983095983089983097 (the pop-ulation o the district) = 983091983091983096983097

2 Methods
Afer 1047297eld surveys and recognition o the available inorma-tion we realized that a study using individual records wasnot easible Tereore we opted or a study using routinely collected grouped data Since this study was retrospective anddid not involve individual inormation ethical approval wasnot required

consulting the birth registerso three health units (Maringue-Sede Canxixe and Phango) Agreement was goodmdashourestimate 983089983096983094983091 estimate made by the central Maringue-Sede983089983096983092983088
983090983090 Identi1047297cation of Vaccinated Children Each health unit
keeps two registers o vaccinations (Livros de Registo deVacinacao de Criancas) ldquoPosto Fixordquo or vaccinations per-ormed at the health unit and ldquoBrigada Movelrdquo or immunisa-tion campaigns perormed in the territory with mobile teamsTe registers contain inormation on sex and date o birth o the newborn and dates o vaccination or each typedose o
vaccine Place o birth is not recorded so they do not allow to identiy the inants born at the health unit and those bornat motherrsquos home Note that when a vaccine dose has beenadministered in another health unit a simple tally sign () iswritten instead o the date From these registers we countedthe number o BCG vaccinations actually administered (iewith a date recorded in the register omitting vaccinations
marked with a tally to avoid multiple counting) to childrenborn in 983090983088983089983089 Although BCG should be administered at birththis is not always the case or several reasons includingchildren born in the community temporary or permanentunavailability o BCG vaccines because o logistic problems(rerigerator ailures or lack o stored vaccines) Tereore inorder to catch late vaccinations we recorded all vaccinationsadministered through June 983090983089983088983090
983090983091 Statistical Analysis Te proportion o inants vaccinatedwith BCG was calculated by dividing the number o BCGdoses administered in 983090983088983089983089 and in the 1047297rst hal o 983090983088983089983090 by thenumber o newborns in 983090983088983089983089 Te 983097983093 con1047297dence interval o the proportionwas calculated using the Agresti-Coull ormu-la [983093] available in the sofware Stata 983089983090 [983094]

Te numbers o children born in 983090983088983089983089 and o BCG dosesadministered in 983090983088983089983089ndash983090983088983089983090 are shown in able 983089 We providedetailed results to give a picture o the births and o vacci-nation activities in the district However calculation o BCGcoverage at the health unit level makes little sense becausechildren resident in the territory o a given health unit may be vaccinated elsewhere or several reasons For examplein the Canxixe health unit the rerigerator when vaccineswere stored ailed in 983090983088983089983089 with a dramatic decrease o the
percentage o vaccinated children (983089983091983088983092983096983096 = 983090983094983094) Logisticproblems have probably occurred also in the Gumbalatsaiwhich also shows a very low coverage (983092983097983090983090983089 = 983090983090983090)Te newly established Phango health unit started vaccinationactivities in April 983090983088983089983089 Te other health units somehow compensated or these problems For example in Maringue-Sede the number o BCG vaccinations(983089983092983091983094) waslarger thanthe number o newborns (983089983090983095983088)

4 Discussion
In the period 983088983089983088983089983090983088983089983089ndash983091983088983088983094983090983088983089983090 we estimated in theMaringue District a BCG coverage o 983096983094983091 or children bornin 983090983088983089983089 Tis 1047297gure is only approximate because we could notrely on careully recorded individual data From BCG resultswe can plausibly iner that or other vaccinationsthe coveragepercentages are lower because they require several dosesadministered weeks to months afer delivery In act alsonational data shows a lower coverage or the other vaccina-tions [983091]
In interpreting the result we must take into accountseveral implicit limits in the use o grouped data First the
number o home deliveries was obtained based on children visits afer birth at the health unit Tis number might havebeen underestimated In a worst-case scenario assuming anunderestimate o 983093983088 (ie 983090983097983092 more children born in thecommunity) the BCG coverage would be 983095983097983091 Second parto the babies could have been vaccinated later in the secondhal o 983090983088983089983090 However this number is likely to be quite smallconsidering that most children (983097983088983097) have been vaccinatedin their birth year (983090983088983089983089) Tird some children (especially those living near the borders o the Maringue District) may have been vaccinated in nearby districts On the other handa reversal 1047298ow o children living outside may have been
vaccinated within the Maringue District Unortunately we
were unable to estimate the net balance because we could notrely on individual data
Beore carrying this study using grouped data we hadconsidered other design options Te 1047297rst option was a clas-sical cross-sectional sample survey called ldquo983091983088 times 983095rdquo whichinvolves the enrolment o at least 983095 children in 983091983088 randomly selected villages [983095] Tis type o study suggested by WHO
in developing countries would also allow to perorm a BCGscar counting (that would give a direct picture o the quality o immunisation) Unortunately thiswas not easible or twomain reasons lack o demographics data and the very largenumber o small amily units spreading over a territory o several tens o kilometres Te second option a cohort study using recorded individual data was also ineasible becausedata linkage was not possible In act the register o birthsonly records the name o the mother while the vaccinationregister initially records motherrsquos name and at ollowing
vaccination visits the childrsquos name Availability o individualinormation would have allowed identi1047297cation o childrenborn outside and inside the district Moreover individ-
ual inormation would be especially important to identiy theunvaccinated children and the reasons or noncomplianceand 1047297nally to target interventions

5 Conclusion
In this study using routinely collected inormation we esti-mated a BCG coverage o 983096983094983091 in the Maringue DistrictTis 1047297gure is only approximate because o the unavailability o adequate individual inormation Our study also under-linesde1047297ciencies o current recording practiceswhichshouldbe changed in order to allow use o individual inormationand linkage across different inormation sources (preerably using computerised archives) and thus a more precise assess-ment o vaccination coverageWeconcur with theauthorso arecent editorial that ldquoa major challenge or [ ] Mozambiqueis to strengthen local capacity or data collection manage-ment and analysesrdquo [983089983089]

4 Discussion
In the period 983088983089983088983089983090983088983089983089ndash983091983088983088983094983090983088983089983090 we estimated in theMaringue District a BCG coverage o 983096983094983091 or children bornin 983090983088983089983089 Tis 1047297gure is only approximate because we could notrely on careully recorded individual data From BCG resultswe can plausibly iner that or other vaccinationsthe coveragepercentages are lower because they require several dosesadministered weeks to months afer delivery In act alsonational data shows a lower coverage or the other vaccina-tions [983091]
In interpreting the result we must take into accountseveral implicit limits in the use o grouped data First the
number o home deliveries was obtained based on children visits afer birth at the health unit Tis number might havebeen underestimated In a worst-case scenario assuming anunderestimate o 983093983088 (ie 983090983097983092 more children born in thecommunity) the BCG coverage would be 983095983097983091 Second parto the babies could have been vaccinated later in the secondhal o 983090983088983089983090 However this number is likely to be quite smallconsidering that most children (983097983088983097) have been vaccinatedin their birth year (983090983088983089983089) Tird some children (especially those living near the borders o the Maringue District) may have been vaccinated in nearby districts On the other handa reversal 1047298ow o children living outside may have been
vaccinated within the Maringue District Unortunately we
were unable to estimate the net balance because we could notrely on individual data
Beore carrying this study using grouped data we hadconsidered other design options Te 1047297rst option was a clas-sical cross-sectional sample survey called ldquo983091983088 times 983095rdquo whichinvolves the enrolment o at least 983095 children in 983091983088 randomly selected villages [983095] Tis type o study suggested by WHO
in developing countries would also allow to perorm a BCGscar counting (that would give a direct picture o the quality o immunisation) Unortunately thiswas not easible or twomain reasons lack o demographics data and the very largenumber o small amily units spreading over a territory o several tens o kilometres Te second option a cohort study using recorded individual data was also ineasible becausedata linkage was not possible In act the register o birthsonly records the name o the mother while the vaccinationregister initially records motherrsquos name and at ollowing
vaccination visits the childrsquos name Availability o individualinormation would have allowed identi1047297cation o childrenborn outside and inside the district Moreover individ-
ual inormation would be especially important to identiy theunvaccinated children and the reasons or noncomplianceand 1047297nally to target interventions
Te de1047297ciencies in the process o immunisation datacollection and reporting that we described earlier were alsonoted by other studies perormed in Mozambique A study evaluated routine surveillance data as a tool to investigatemeasles outbreaks in Maputo (983089983097983097983096) and Manica Province(983090983088983088983090) [983096] It wasconcluded that the reporting system did notprovide the data needed by EPI managers to make evidence-based decisions and precluded in-depth analysis to monitormeasles epidemiology in the country An improvement o routine surveillance and health inormation systems (HISs)

4 Discussion
In the period 983088983089983088983089983090983088983089983089ndash983091983088983088983094983090983088983089983090 we estimated in theMaringue District a BCG coverage o 983096983094983091 or children bornin 983090983088983089983089 Tis 1047297gure is only approximate because we could notrely on careully recorded individual data From BCG resultswe can plausibly iner that or other vaccinationsthe coveragepercentages are lower because they require several dosesadministered weeks to months afer delivery In act alsonational data shows a lower coverage or the other vaccina-tions [983091]
In interpreting the result we must take into accountseveral implicit limits in the use o grouped data First the
number o home deliveries was obtained based on children visits afer birth at the health unit Tis number might havebeen underestimated In a worst-case scenario assuming anunderestimate o 983093983088 (ie 983090983097983092 more children born in thecommunity) the BCG coverage would be 983095983097983091 Second parto the babies could have been vaccinated later in the secondhal o 983090983088983089983090 However this number is likely to be quite smallconsidering that most children (983097983088983097) have been vaccinatedin their birth year (983090983088983089983089) Tird some children (especially those living near the borders o the Maringue District) may have been vaccinated in nearby districts On the other handa reversal 1047298ow o children living outside may have been
vaccinated within the Maringue District Unortunately we
were unable to estimate the net balance because we could notrely on individual data
Beore carrying this study using grouped data we hadconsidered other design options Te 1047297rst option was a clas-sical cross-sectional sample survey called ldquo983091983088 times 983095rdquo whichinvolves the enrolment o at least 983095 children in 983091983088 randomly selected villages [983095] Tis type o study suggested by WHO
in developing countries would also allow to perorm a BCGscar counting (that would give a direct picture o the quality o immunisation) Unortunately thiswas not easible or twomain reasons lack o demographics data and the very largenumber o small amily units spreading over a territory o several tens o kilometres Te second option a cohort study using recorded individual data was also ineasible becausedata linkage was not possible In act the register o birthsonly records the name o the mother while the vaccinationregister initially records motherrsquos name and at ollowing
vaccination visits the childrsquos name Availability o individualinormation would have allowed identi1047297cation o childrenborn outside and inside the district Moreover individ-
ual inormation would be especially important to identiy theunvaccinated children and the reasons or noncomplianceand 1047297nally to target interventions
Te de1047297ciencies in the process o immunisation datacollection and reporting that we described earlier were alsonoted by other studies perormed in Mozambique A study evaluated routine surveillance data as a tool to investigatemeasles outbreaks in Maputo (983089983097983097983096) and Manica Province(983090983088983088983090) [983096] It wasconcluded that the reporting system did notprovide the data needed by EPI managers to make evidence-based decisions and precluded in-depth analysis to monitormeasles epidemiology in the country An improvement o routine surveillance and health inormation systems (HISs)
