Background: Pharmacists practice in a broad multidisciplinary area including community, hospital, industrial, academia, regulatory and practice where they offer therapeutic interventions on drug and medication efficacy, safety and appropriate regimen. Pharmacists have a key role to play to advance public health through immunization. Pharmacists are well trained and play a huge role in vaccine production, research and development, safety, pharmacovigilance, storage, logistics and distribution. This study presented an overview of Community Pharmacies and immunization services in Nigeria and generated information for intervention, outcomes, and policymaking. This study is an overview of Community Pharmacies and immunization studiesand Services reviewed in Nigeria by adopting a narrative review literature writing style.The study was a retrieved literature search conducted on computerized databases. Search terms were used singly, in combination, and truncation to select and synthesize articles. Only studies carried out in Nigeria and written in the English Language with clear study design from 1980 to 2023 were utilized. The data obtained were subjected to descriptive statistics of frequency, percentage, and comparative assessment using the Oxford and Scottish Benchmarks for Study Standard. A total of 17 articles met the criteria and were used for the study. The highest incidence of the articles selected was studied in south-west10 (58.82%), followed by south-south 4(23.53%), respectively. Nationwide has a distribution of 1(5.88%), and South-east had the same number of articles selected 1(5.88%) respectively, while north-west and north-east had 0(0.00%) article selected. However, the north-central had the highest number 1(5.88%) of articles cited in the north, respectively. No article on Community Pharmacies and immunization services was cited before the year 2000 0(0.00%) while the highest number of studies 8(47.06) was conducted between 2021 and 2023, and 7(41.18%) between 2011 and 2020 respectively. The studies were found to fall within the lower half of the Oxford and Scottish benchmarks for the hierarchy of studies and study standards.
Conclusion: To maintain and improve coverage, uptake and information dissemination in vaccination and national immunization programs, pharmacists/pharmacies should be involved to contribute to this effort and be prepared to respond to public concerns as part of the scope of pharmacy practice in Nigeria. Most of the studies were predominantly carried out in the western, eastern, and central parts of Nigeria. Nonrandomized intervention studies were available and cross-sectional descriptive surveys were the leading study design carried out which fell within the lower half of two standard benchmarks (Oxford and Scottish) for the hierarchy of studies. Although, Randomized Control Trials (RCTs), narrative reviews, systematic reviews, and meta-analysis of RCTs of PC studies were still not available in the country.
The historical model that medical practitioners diagnose disease and prescribe medicines, while pharmacists’ compound and dispense medicines, continues to be the expectation of many medical doctors and a large part of the general public even though new extended pharmacy roles have been shown to have a significant impact on health care management and health care expenses in the long-term [1]. However, pharmacists are challenged to become key players in optimizing and monitoring medication use and to become advocates for patients [2]. Vaccines are known to stimulate the body's immune system for protection against subsequent exposure to the pathogen or disease while immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine [3].
Pharmacists' role in vaccination and immunization currently varies across countries in the world. They are empowered to play active roles in ensuring the safe supply, storage, administration and dispensing of vaccines, legally authorized to organize vaccination activities and campaigns, advocating for immunization as well as the integration of community pharmacies and pharmacists in national policies [4]. In Nigeria, the vaccination schedule is drafted as per the National Program on Immunization (NPI). The vaccines are administered across a wide range of government and private hospitals, yet pharmacies and/or pharmacists are not involved in the administration of vaccines and this has posed a great limitation to the uptake of vaccines. Globally, it is estimated that existing immunization programs prevent over 2–3 million deaths annually that could have resulted from vaccine-preventable diseases (VPDs) and approximately 19.4 million children missed out on basic vaccination [5].
This places a great economic burden on VPDs as millions remain susceptible to potentially deadly VPDs despite effective vaccine availability. Although there is no official restriction limiting community pharmacists from providing immunization services in Nigeria, there have not been any policy directions or law towards the involvement of them into that [6]. This has caused limited acceptance and support by the healthcare system to recognize pharmacists as an integral member of the vaccine workforce. Nevertheless, there have also been pharmacist-led organizations who have been championing the inclusion of pharmacists in the vaccine workforce in Nigeria to resolve vaccine hesitancy. In middle and low-income countries where vaccine services are being offered, there is also diminishing perceived competition threat to other healthcare professionals providing immunization services through greater advocacy and wider coverage [4]. This will help Nigeria also in establishing a greater healthcare delivery workforce for the societal benefits of the country and demonstrate the full potentials of the community pharmacies and the pharmacists' role in immunization programs.

An Overview of Community Pharmacies and immunization services in Nigeria
Pharmacists' role in vaccination and immunization currently varies across countries in the world. They are empowered to play active roles in ensuring the safe supply, storage, administration and dispensing of vaccines, legally authorized to organize vaccination activities and campaigns, advocating for immunization as well as the integration of community pharmacies and pharmacists in national policies [4]. In Nigeria, the vaccination schedule is drafted as per the National Program on Immunization (NPI). The vaccines are administered across a wide range of government and private hospitals, yet pharmacies and/or pharmacists are not involved in the administration of vaccines and this has posed a great limitation to the uptake of vaccines.
Globally, it is estimated that existing immunization programs prevent over 2–3 million deaths annually that could have resulted from vaccine-preventable diseases (VPDs) and approximately 19.4 million children missed out on basic vaccination [5]. Therefore, in order to maintain and improve coverage, uptake and information dissemination in vaccination and national immunization programs, pharmacists/pharmacies should be involved to contribute to this effort and be prepared to respond to public concerns as part of the scope of pharmacy practice in Nigeria. Above all this new extended model of practice by community Pharmacists in community Pharmacies is at its infancy in Nigeria healthcare system.
Notwithstanding, Over the years, there is no official restriction limiting community pharmacists from providing immunization services in Nigeria, there have not been any policy directions or law towards the involvement of them into that [6]. This has caused limited acceptance and support by the healthcare system to recognize pharmacists as an integral member of the vaccine workforce.
Nevertheless, there have also been pharmacist-led organizations who have been championing the inclusion of pharmacists in the vaccine workforce in Nigeria to resolve vaccine hesitancy. There have been consistent records from various studies showing that availability, attitude, knowledge, barriers, participation, have great effects on Community Pharmacies/Pharmacists providing an extended role on immunization within the healthcare system as the medical profession, other team players in the health care team and populace perceives it as an encroachment of the community Pharmacies/Pharmacist into their excluded right of direct care to the patient and the pharmacist perceives it as a marginalization of their profession, negative attitude between the healthcare team and pharmacist can result in negative collaborative care and also poor communication and over-expectation from both parties can stand as a big barrier in delivering a good immunization services to the populace and as such the idea of vaccination would be defeated if left unattended [28]. However, Observational studies were the best fit in accessing and analyzing the Community Pharmacies/Pharmacists and immunization services across various variables in Nigeria this corresponds to the distribution of the studies showing a higher incidence of non-experimental studies in the country. This could also be as a result of the relative ease in the conduct of an observational study than experimental studies.
Also, due to the reduced cost, manpower, and time employed for an experimental study. Most of the studies cited in the work were also carried out within the last two decades as shown in table 1 and 5, recording 2(11.76%) within the decade of 2001 to 2010 and the next following decade (2011-2020) recording 7(41.18%) and the present decade (2021-2023) recording 8(47.06%), while the decade of 1980-2000 recording no cited work 0(0.00%). This is largely because the concept of Community Pharmacies and immunization services first evolved from the European countries and it’s been gradually adopted by the Nigerian government when because it gives a better outcome in reaching out to more of the populace through the vaccination process which was introduced within the last 2 decades and it has been gradually adopted by Pharmacist’s domicile in the community practice setting.
Description of the Community Pharmacies and immunization services and the extent and nature of work done in Nigeria
Table 2 revealed the regional distribution of the articles and the study focus of each region. It showed that the highest number of studies were done in South-west 10(58.82), closely followed by South-south 4(23.53%) respectively, followed by the South-east, North central and Nationwide 1(5.88%) of the country respectively. There was no article cited in the North-west and north-east 0(0.00%). The theme of the works conducted in North-central, South-east, South-west, South-south comprised of the impact of the knowledge, attitude, participation and perception between community Pharmacists and immunization services, while that of the North-west, North-east, and Nationwide focused more on the importance of community Pharmacists and immunization services, knowledge, attitude, readiness and perception of community Pharmacies on immunization services.
Most of the works were done within South-east, South-west, South-south region possibly because the majority of the medical and pharmaceutical schools are domiciled there and besides, it is easier to access your patients directly and deliver immunization services in these regions due to less restriction to female genders as well as moral and societal impediments. The Nationwide studies also provided for comparative analysis between regions, states, and more within the year. The few studies cited in the northern region mainly focused on the readiness of community pharmacist to deliver and recommend good immunization services. Among the Northern region, North-Central posed to have higher works 1(5.88%) carried out as opposed North-east 0(0.00%) and North-west 0(0.00%) respectively.
Description of Community Pharmacies and immunization services and comparisons of the studies to the oxford and Scottish benchmarks for the hierarchy of clinical
As shown by Table 4 on the hierarchy of studies, observational studies had the only recorded number studies 17(100%). Studies in the hierarchy other than nonrandomized intervention studies, had no record as observational studies presumably were the best fit in accessing and analyzing the collaborative differentials across various variables. Most of the studies cited were surveys carried out using questionnaires as the instrument of study. Although the questionnaires were used directly on the respondents. A few of the studies involved immunization and vaccination but most of them were focused on community Pharmacies/Pharmacists. As portrayed by Table 3 on the Evidence-based Medicine Evidence level, Case series, poor quality cohort, and case-control studies was the only score of 17(100%) while the rest of the study with a 0(0.00%) score. This shows that community Pharmacies and immunization services in Nigeria are still in their infancy.
There is a need for a revised national policy and strategy in Nigeria on vaccination and immunization programs with the involvement of community pharmacies and/or pharmacists. Community pharmacy is one of the most accessible and most frequently consulted points of care to the public. Indeed, community pharmacies represent healthcare settings in the community where vaccines can be given to the public as pharmacists play a great role and are very well informed about vaccine product characteristics, manufacturing specificities and complexity, vaccine research and development. This will help accelerate getting a wider vaccination access coverage, establishing a greater healthcare delivery workforce for societal benefits and demonstrate the full potential of the community pharmacies and the pharmacists’ role in immunization programs.
Many of the articles cited were studies carried out on Community Pharmacies and immunization services within the Nigerian healthcare system. Most of all the studies conducted were observational. The distribution of the studies recorded a higher incidence of the study conducted South-east, South-west, South-south as compared to the various other regions. The studies fell short of the Oxford and Scottish benchmarks for the hierarchy of studies showing that the community pharmacies and immunization services activities in Nigeria are at their primary level.
The possibility of omission due to search and search terms limitations. Some of the studies cited may have some level of bias that escaped elimination which could have an impact on the outcome of the study. The method of presenting tables and data in the present study was purposively chosen for simplicity and clarity even though they could be better presentation formats.
