It is affordable Catching the It is effective It is not hard to There is lots of
chickens is not administer information about
difficult it available

EO: Farmers lie about diseased chicken to
get them vaccinated….
I train the vaccinators on handling, giving
injections, side affects
Vx: People complain about the
amount charged….
3 out of 10 don’t pay…..
I have received no training…
Some sell vaccine to rich households
and use water to vaccinate the birds of
the poor households to make money
FGD: We are willing to pay 100 TSH
(twice the price currently charged)
