The Agency also produces and sells vaccines, traps, targets and sheep blood. The following are Vaccine produced by TVLA

  • Newcastle vaccine (I-2)

This is a thermostable live attenuated vaccine meant to control Newcastle disease (ND) in local chicken. Newcastle Disease is a major problem in the development of local chickens as it causes high mortality rate (up to 90%) and sometimes devastates whole flocks during outbreaks. Control of ND in local chickens in the past had very limited success as most of the vaccines used were heat sensitive and supplied in large doses vials not affordable for most rural farmers. Also the vaccines were thermolabile requiring cold chain system for their distribution that is lacking or deficient in most rural areas. This obstacle is now overcome through the development of a thermotolerant ND vaccine (I-2). The vaccine is affordable and packed in small vials containing 400 doses of which one dose is a single drop administered in one eye. This pack suffices the needs of most local chicken keepers considering the number of chicken normally kept in the household. This vaccine is easily administered by eye droppers, effective and sustainable and can be without refrigeration for up to three weeks. In order for the chicken to be protected, three vaccinations are required and to be given at interval of every four months. In the pilot study conducted in Singida from (2002–2005) and more recently (2009-2010) through the Southern Africa Newcastle Disease Control Project (SANDCP) and ND Control Regional Project respectively,Tanzania has done well in the control of ND in village chickens by sustaining three times vaccination regimen in a year. Given the pilot successes, the demand for expansion of the service is proving to be necessary in order to control ND in Tanzania and therefore increased production to a large quantity.

 

  • Black quarter vaccine (BQ)

This is a dead bacterial vaccine meant to control Black quarter (BQ) in cattle, sheep and goat. Black quarter is a major disease of ruminants in Tanzania and may cause up to 60% mortality in livestock. Control of BQ in endemic areas in the past had very limited success as vaccine was not readily available, expensive and required importation. This obstacle is now overcome through the development of a vaccine we make from our local strain. Successes in control of disease are mentioned in Kwimba, Maswa and Kahama where the disease outbreaks had been occurring yearly and now the vaccine is used. The vaccine is affordable and packed in battles of 100ml containing 50 doses of which one dose is 2ml. This suffices the needs of most livestock keepers considering the herd size of most household. This vaccine is effective and administered by subcutaneous injection. The vaccine confers immunity for one year and therefore animals need to get annual boosters. This requires sustainable production of the vaccine to enable availability in the market. The vaccine requires cold chain for storage.

  • Anthrax vaccine

This is a live spore bacterial vaccine meant to control Anthrax in cattle, sheep goat, pig, ostrich, horse and camels. Anthrax is a zoonotic disease which in Tanzania occurs in many parts and outbreaks have been reported in Iringa, Arusha, Dodoma, Singida, Mbeya, Morogoro, Kilimanjaro, Manyara and others places. In these places where outbreak was reported also human beings have been reported to be infected. Control of Anthrax in the past had very limited success as vaccine was not readily available, expensive and required importation. This obstacle is now overcome through the development of a vaccine we produce. A success in control of disease is now realized through reports of reduction of anthrax cases in the country with sporadic cases occurring in areas where vaccine has not been used. The vaccine is affordable and packed in battles of 100ml containing 100 doses of which one dose is 1ml. This pack suffices the needs of most livestock keepers considering the herd size of most household. This vaccine is effective and administered by subcutaneous injection. The vaccine confers immunity for one year and therefore animals need to get annual boosters. This requires sustainable production of the vaccine to enable availability in the market. This vaccine requires cold chain for storage.

  • Brucella vaccine (S19)

This is a live attenuated bacterial vaccine meant to control Brucellosis in cows. It is vaccinated to young females between 3 to 9 months of age. Brucellosis is a zoonotic disease which occurs in Tanzania and disease has been reported in Iringa, Arusha, Coast, Dodoma, Singida, Mbeya, Morogoro, Kilimanjaro, Shinyanga, Kagera, Manyara and others places. In many places where disease was reported also human beings have been reported to be infected. Control of Brucellosis in the past was difficult due to unavailability of vaccine and when possible was expensive and required importation from abroad. This obstacle is now overcome through the development of a vaccine we produce. A success in control of disease is now realized through reports of reduction of Brucellosis cases in the country with sporadic cases occurring in areas where vaccine has not been used. The vaccine is affordable and packed in battles of 100ml containing 20 doses of which one dose is 5mls. This pack suffices the need of most dairy cow keepers considering the herd sizes of smallholder farmers. This vaccine is effective and administered by subcutaneous injection. The modernization of livestock farming and sensitization to increasing dairy farming in the country requires sustainable production of the vaccine to enable availability in the market. This vaccine requires cold chain for storage.

 

The following are Traps and Targets available at TVLA

These are devices that are developed to catch and kill tsetse flies in order to control trypanosomosis. They are made resembling shape of animal and of clothes of two colours which are black and ocean blue. The clothes choice is due to visual attraction of tsetse to the colours. During deployment the iron rods or tree sticks are used to shape the traps and targets and stabilize them on the ground. Traps and targets are normally put together with attractants which release the smell like that of animals to attract tsetse on the trap or target. Traps and targets are deployed and attractants are positioned on the direction of the wind to reach the tsetse resting and hiding places. Traps are made in such a way that the tsetse flies caught are collected in the cone at the apex of the trap. Traps are mainly for catching tsetse for sampling the population during surveys for baseline data and monitoring while targets are cloth screens impregnated with insecticides and are meant for killing tsetse flies landing on them during control. The traps and targets are used during tsetse control programmed to reduce the population prior to eradication phase. They are used in tsetse infested areas, areas surrounding reserved areas and in reserved areas. The use of traps and targets has shown a remarkable success in reducing tsetse population in the infested areas. Therefore, there is a need to continue using these devices for sustainable trypanosomosis control in the country.
