NATIONAL IMMUNISATION DAYS IN BAMENDA HEALTH DISTRICT

NATIONAL IMMUNISATION DAYS IN BAMENDA HEALTH DISTRICT, CAMEROON, 1996 – May 2005



INTRODUCTION
National immunisation days (NIDs) constitute supplementary vaccination activities carried out in the entire nation. Synchronised immunisation days (SNIDs) are supplementary vaccination activities that are carried out at the same time by countries sharing common land and sea boarders. Local national immunisation days (LIDs) concerned only Provinces/Health Districts of the Nation sharing common boarders with neighbouring countries that are still declaring cases of wild poliovirus, or Provinces/Health Districts declaring cases of measles or hepatitis B or any other cases of vaccination preventable diseases. Vaccination campaigns will be used indifferently to represented them.

Poliomyelitis is an infectious disease caused by a virus the ‘wild poliovirus’ resulting in the paralysis of the arms or the legs. Children below 5 years are particularly vulnerable. The wild poliovirus is transmitted from an infected person to a non-infected person through the oral-faecal route. To prevent poliomyelitis each child should be completely vaccinated before the age of one year according to the national vaccination calendar of the Extended Programme on Immunisation (EPI); and should receive all the prescribed doses of polio vaccine during the national immunisation days against poliomyelitis.

National, synchronised and local immunisation days against poliomyelitis were organised in Cameroon, including the Bamenda Health District from 1996 to May 2005. The target population for National Immunisation Days against poliomyelitis is children aged 0 – 59 months. In 2002 national immunisation days against measles were effected for children 9 months to 14 years old. During some of the national immunisation days Vitamin A was administered to children 6 – 59 months. The objective of this write up is to describe the implementation process and state the results of immunisation days in Bamenda Health District from 1996 to May 2005.

GAOLS OF IMMUNISATION DAYS
1) Eradicate poliomyelitis.
2) Reduce morbidity due to measles.
3) Reduce morbidity due to Vitamin A deficiency.

OBJECTIVES OF NATIONAL IMMUNISATIONS DAYS:
1. Vaccinate all children 0 - 59 months against poliomyelitis.
2. Vaccinate all children 9 months to 14 years against measles.
3. Administer Vitamin A to all children 6 to 59 months.
4. Stop the cross-border propagation of wild polio virus through the SNIDs
5. Carry out active surveillance of acute flaccid paralysis (AFP) in children less than 15 years.
6. Educate population to adhere to the routine Expanded Programme on Immunisation.

METHOD:
Data were obtained from the following sources:a) Archives in the District Health Service
b) Reports in the office of the District Health Service
c) Archives in the Provincial Delegation of Public Health, North West
d) Reports in computer from 2001 to August 2005.

The results, sources of information of parents, some causes of refusals, and funding of some NIDs will be presented.

PREPARATORY PHASE:

a) Planning

The Central Level, the Ministry of Public Health, determines the dates and types of national immunisation days, based on results of epidemiological surveillance.
At the level of the Health District a microplan is elaborated for each national immunisation days using the national planning tool.
In Bamenda Health District each Health Area elaborates an operational one-sheet micro plan for the NID.
Members of District Health Service, Chiefs of Centres, supervisors, vaccinators, social mobilisers, and Community Members of the District Management Committee are trained.
Vaccines and materials are received and distributed.

b) Social mobilisation

Letters for social mobilization and advocacy are written to the Administrative Authorities, Traditional, Religious and Political Leaders, during each phase of the NIDs.
Community Members of the District Management Committee are trained as focal points for social mobilization.
Advocacy meetings are held before the NIDs.
Spot messages are written, recorded and broadcasted by all the radios in Bamenda; it is also used with the public announcement system of the District Health Service to mobilise the population for the vaccination campaign.

c) Tools used during NIDs

- Tally sheets
- Daily evaluation form
- Technical reports form
- Financial report form
- Rapid assessment questionnaire
- Form for investigation of refusals
- Form for the supervision of vaccination teams
- A sheet describing the numbering and marking of children used by each vaccination team.
This list of tools is not exhaustive.

d) Excel Computer Programmes

The author elaborated excel computer programmes for the synthesis of data collection tools used for the NIDs as from 2001, (the programmes always conformed to those from the Central Level):
- Daily evaluation form for children vaccinated, those receiving Vit A, and number of houses visited.
- Technical reports from health areas
- Financial report from health areas
- The summary form of the rapid assessment questionnaire.

IMPLEMENTATION PHASE

The local Administrative Authorities or the Minister of Public Health, or Traditional Rulers launched most of the vaccination sessions, at various levels.
The strategy for the NIDs is door-to-door for Polio; fixed and temporary sites for Measles. However the strategy for NIDs Polio evolved from fixed in 1996 to door-to-door 2000, and to door-to-door in 2001 and thereafter. Supervision is intense during NIDs with supervisors from different levels:
- Health area supervisors: responsible for the immediate supervision of vaccination teams
- District Supervisors responsible for the supervision of Chiefs of Centres and vaccination teams.
- The Provincial Supervisors responsible for the supervision of District Health Team, Chiefs of Centres and vaccination teams.
- The National Supervisor from the Ministry of Public Health
- Supervisors from either the World Health Organisation, or UNICEF
- International Consultants

Daily evaluation meetings involving the Chiefs of Centres, the District supervisors, and Community Representatives of District Management Committee, Provincial supervisors; and sometimes the National supervisors and International Consultants are held. There is a daily review of results and rapid assessment forms; positive points and weaknesses are identified and orientations for the following day adopted.

Daily Health District synthesis are made using the excel programmes, and forwarded to the Provincial Delegation of Public Health.

RESULTS OF NATIONAL IMMUNISATION DAYS

The duration of NIDs Polio varied from three days in 1996 to 2000, then five days from 2001 to April 2005, and then three days May 2005. The NIDs Measles in 2002 planned for eight days was extended to ten days because of religious feast days.
The results of vaccination campaigns for polio ranged from 65% and 34.9% in 1996 to 115.0% in 2001. Detailed results are shown in the tables and graphs below.
The cost of the vaccination, campaigns varied from 3136560 to 6507400 francs CFA with and average of 4633100 francs for the eleven vaccinations campaign finances considered. The average cost per child is 110 francs.
The money spent for the measles campaign of 2002 was 9442180 francs CFA with 53.0% from WHO, 36.6% from local running credits, and 10.4% from health centre funds.

The main sources of finances are the local running credits, WHO and UNICEF, local health centre funds.

The main sources of information of parents of children as revealed by the rapid assessment were the radio 29.7%, criers and mobilisers 24.5%, churches/mosques 22.5%, and television 16.4%

The main reasons for refusals identified were children absent 47.1%, refusal by parent 17.6%, and guest child/newborn 23.5%; houses not visited 11.8% out of 17 children; all theses children were vaccinated.

All houses and stores were numbered as from the vaccination campaign of 2003; children were also systematically marked with nail polish.

DISCUSSIONS
The lowest coverage rate for Polio vaccine (65.0% and 34.9%) were obtained in 1996 because of the administration of all the vaccines of routine EPI (BCG, Polio, DPT, Measles), but after evaluation only one antigen was adopted for NIDs from 1997, sometimes with the administration of Vitamin A.

The quality of vaccination campaigns has improved over the years through the introduction evaluation tools, training of personnel, exclusive door-door-door strategy, rapid assessment, intensive supervision, numbering of houses and stores at the markets, and marking of children.

Social mobilisation is very high with the involvement of all authorities thus all refusals are vaccinated; although advocacy meetings produce very little resources. The Bamenda Urban Council and the Tubah Council offer donations.

The radios plays a very important role in social mobilisation in Bamenda, however they must be assisted by the District Health in producing a spot for broadcasting and sponsoring the cost.

A large proportion of the financing of vaccination campaigns comes from local contributions by health services through especially running credits above 34.4%.

The refusals are usually few and convinced through dialogue with the health teams at all levels including the Administrators and District focal mobilisers.

The number of children who has never received polio vaccine has greatly reduced to only few newborn of the previous night.

The active search for AFP yielded no confirmed case.
The population for the vaccination campaigns is usually updated from the highest target population vaccinated the previous year consequently there is usually no shortage of vaccine.

The radio spots conceived and produced by the author, and broadcasted over all the radio stations, although at a very high cost, plays a predominant role in social mobilisation. However sources of information varied according to health area urban/rural. The role of social mobilisers cannot be neglected.

The number of declared suspected cases of measles has greatly dropped and no case of measles has been confirmed since the NIDs against measles in 2002. The absence of measles in the community has resulted to a false impression by the population that there is no need to vaccinate children against measles again.

One always encounters inadequate finances despite the heavy use of local service finances that usually diminished according to the number vaccination campaigns during the year. There is need for aprons for all teams to facilitate recognition by the population

Communication of financing of SNID at the National level should be moderated and should include an open appeal for community participation and support of the SNID at all levels.

Social mobilisers who know their quarters very well and also well known; who participate in drawing up the itineraries and maps should constitute a member of the vaccination team even if the team is only made up of two persons.

CONCLUSION
The population has experienced the impact of vaccination campaigns for they no longer observe measles and paralysis due to poliomyelitis in the community and thereby seeing no need for vaccination. It is therefore necessary for the health personnel to intensify educate and mobilise the population to continue to vaccinate their children.

It was difficult to obtain all the results because of poor documentation system; it is therefore highly recommended that every staff should be committed to an effective filing system. Hard copies of reports in computer should be made periodically, and electronic backups should be made in order to facilitate the application the health management information system.

It is absolutely essential to elaborate simple computer excel programs for the exploitation and synthesis of all the tools used in the SNID. The author has been taking a lot of initiative in producing excel programs that enhance easy reporting. Any level can acquire this expertise in order to accomplish an excellent work.

With the enthusiasm, commitment and involvement of all the partners, community, health committee members at all levels, health personnel, the Administration and traditional rulers one should be very optimistic that Bamenda Health District will continue to play its own important role towards the eradication of wild poliovirus in Cameroon.

EPI IN BAMENDA HEALTH DISTRICT, CAMEROON, FROM 1999 – AUGUST 2005

EXPANDED PROGRAMME ON IMMUNISATION (EPI) IN BAMENDA HEALTH DISTRICT, CAMEROON, FROM 1999 – AUGUST 2005

INTRODUCTION
The Expanded Programme on Immunisation is implemented in Bamenda Health District as defined by the Central Level – The Ministry of Public Health in the norms and standards of the Expanded Programme of Immunisation.
The target populations concerned are children 0-11months, with the administration of Vitamin A to children to children from 6 month to 5years, and pregnant women as indicated in the following calendars.

View image on next POST
The sources of total population have varied from local health census for1999, through the national immunisation days for 2000 and 2001, to the update of National Census of 1987 from 2002 to 2005 using the growth rate of 2.9% as shown in the table below.

Sources of total populations

View image on next POST
The target population for children 0-11 months is 4% of the total population and that of pregnant women is 5% of the total population.
The Health District synthesis of EPI returns from Health Areas was done manual until 2000. In 2001 the District Health Service obtained a computer from running credits. The author developed an excel computer programme for the District synthesis that was adapted and improved upon as the Central Level - Ministry of Public Health, modified the data collection tool for health areas, from 2001 to August 2005.

THE GAOL of EPI is to reduce the infant morbidity and mortality due the child hood diseases preventable by vaccination to the lowest level; and to eradicate poliomyelitis in association with Polio National Immunisation Days (NIDs).

THE OBJECTIVE of EPI for Bamenda Health District for 2005 is to obtain 70% vaccination coverage rate for DPT 3 (BCG, Measles, and Polio 3) for children 0-11 months; and Tetanus Toxoide 2+ (TT2+) for pregnant women. The national objective is 80% vaccination coverage rate.

GOAL OF THE REPORT

The goal of the report is to present the results of Routine EPI for children 0-11 months from 1999 to August 2005 to serve as a reference for the improvement of performance and research.

OBJECTIVES
- Present a summary table of results from 1999 to August 2005
- State the results of main indicators of EPI for children 0-11 months.
- Present graphs of indicators.
- Show graphic result of the evaluation of vaccination coverage during the Demographic and Health survey carried out in 2005.

METHOD
Results of EPI returns from 1999 and 2000 were extracted from the register in which synthesis were done manually.

The excel computer programmes provided the District syntheses of EPI returns from 2001 to August 2005.

RESULTS:

The results are presented in the tables and graphs below.

Indicators of EPI for children 0-11 months:

View image on next POST

DISCUSSIONS:

The number children 0-11 months having received DPT3 varied from 4662 in 1999 to 6341 in 2004 with decrease in 2001 and 2003. The vaccination coverage rates fluctuated during the period with high coverage rates in 1999, 2000, and 2003 especially for DPT3. The lowest coverage rates for DPT3 were recorded in 2001 and 2003.
The coverage rate for DPT3 rose from 56.3% in 2003 to 63.5% at the end of August 2005.

Some contribution factors to increase in vaccination coverage rates:
- Daily vaccination at vaccination centres
- Facilitative Supervision by District Health Team, the Provincial Delegation, and Central Level
- The supply of fridges to all vaccination centres in the Health District
- The supplementary support given by Global Alliance for Vaccines and Immunisation (GAVI)
- The motivation and commitment of social mobilisers and staff to reach every child
- The introduction of tools to improve data collection and monitoring
- The creation of some functional health areas.
- Active search of drop outs
- Intensive social mobilisation both by mobilisers in health areas, and by the radios in Bamenda

Some contribution factors to low vaccination coverage rates:- Closure of routine vaccination centres during National Immunisation Days
- Non application of daily vaccination despite the presence of a fridge
- Human errors in recording, extracting and compiling of data at vaccination centres
- The chronic insufficient human resources

The vaccination coverage rate for DPT3 in the North West Province obtained from the demographic and health survey in 2004 was 82.9%, with 76.0% of children having vaccination cards, the highest in the Country. The total population might influence the vaccination coverage rates. The number of declared suspected cases of measles has greatly reduced since the NIDs against Measles in 2002, with no confirmed case of measles, although the measles vaccination coverage rate has been between 52.1% in 2003 to 55.3% in August 2005.

The population erroneously believes measles vaccination is no longer necessary because they do not observe measles cases again in the community. The health personnel should increase social mobilisation to bring children for vaccination against measles.

The appreciation of the real vaccination coverage rate for the Health District could be done through carrying out survey in the community yearly to evaluate the vaccination coverage rate, pending the next national census.

A form for recording children and vaccines received during vaccination sessions to improve identification and quality of data.

CONCLUSION

There has been a lot of input for the improvement of routine EPI although the 2005 objective of 70% vaccination coverage rate for DPT3 has not yet been attained, 63.5% in August 2005.

Two methods of evaluation could always be used to evaluate the output of the programme in the field and the level of achievement of the EPI objectives at all levels:
- The vaccination coverage rates are obtained from the monthly returns, and
- A yearly survey in the community is carried out to evaluate the vaccination coverage rates.

The combination of the routine EPI and NIDs especially the vaccination campaign against measles has revealed the effectiveness of vaccination to the population but there still has to be permanent and continuous social mobilisation vis-à-vis vaccination.
