Technical feasibility characteristics of Hepatitis B vaccination for aflatoxin risk reduction in Africa.
| Category | Criteria | Intervention |
|---|---|---|
| Intervention Characteristics | ||
| Basic product design | Stability | Vaccine should be stored between 2°C to 8°C (refrigerated, not frozen) (Drugs.com 2009) |
| Standardization | Necessary to ensure that all vaccine doses are the same for a given target group, and safe for that group | |
| Safety profile | This vaccine is very safe. The most common side effect is pain at the site of injection. There is no clear association to other serious side effects (NFID 2009). | |
| However, it is crucial that needles be kept sterilized and that vaccines be kept refrigerated. | ||
| Ease of storage and transport | Vaccines require cold storage (See above; applies to transportation conditions as well) | |
| Supplies | Need for regular supplies | To reduce HBV prevalence, multi-generation vaccination is needed. Therefore regular supply of vaccine is required |
| Equipment | High-technology equipment and infrastructure needed | Cold storage is necessary to preserve the vaccines, which can be a challenge in areas without electricity. |
| Existing infrastructures in hospitals and other health centers can facilitate vaccination. | ||
| Number of different types of equipments | Temperature controlled chambers/containers | |
| Needle syringe | ||
| Antigen-antibody titer check | ||
| Delivery characteristics | ||
| Facilities | Retail sector | Vaccines must be provided by a reliable source to ensure efficacy, cleanliness, and proper dosage |
| Outreach services | Mobile vaccination services (door-to-door) may be possible and desirable in certain communities | |
| First level care | Community education on HBV's health effects and how to prevent infection is desirable | |
| Hospital care | Clinics can provide vaccination to infants and previously unvaccinated, uninfected people | |
| Human resources | Skill level required for service provision | Nurses, medical assistants or other trained personnel to administer vaccines |
| Skill level required for staff supervision | Medical staff required | |
| Intensity of professional services (frequency/duration) | Regular service is required to supply vaccines to health care facilities | |
| Management and planning requirements | Because this vaccine is not locally manufactured in most of the high-HBV-prevalent countries, planning and management of vaccine inventories and funding are two requirements. Planning should also cover how the vaccine reaches the target population, evaluation, and up-scaling of the program. | |
| Communication and transport | Delivery dependence on communication and transport infrastructure | Cold storage needed. To reach large proportions of the target population, it is important to distribute this vaccine to every part of the country: all local clinics and health centers, if possible. |
| Government capacity requirements | ||
| Regulation/ legislation | Need for regulation | No special regulation is required, but government must see HBV vaccination as priority to mobilize resources |
| Management systems | Need for sophisticated management systems | Clinics and other health care centers must be connected with vaccine supply outlets, and staff should be trained to administer vaccines. |
| Collaborative action | Collaborative efforts within government sectors and between government and other groups | Health departments within each nation should coordinate with each other and international health organizations to provide vaccines regularly where needed. External funding is necessary, because in order to achieve widespread vaccination, continuity of the program is a vital part. Without external funding or support from external agencies, it can be difficult for poorer nations to maintain this program. |
| Usage characteristics | ||
| Ease of usage | Need for information / education | Individuals must understand need for vaccine as well as where and how often to obtain it, for themselves and their children. |
| Pre-existing demand | Need for promotion | Vaccination has already been promoted in many African nations, but especially in rural areas, greater effort is needed to educate the public on benefits of vaccines. |
| Black-market risk | Need to prevent resale/counterfeiting | Low risk of resale or counterfeiting |
