OSPE

Population of sub centre = 6000

Birth rate = 20/1000

CBR = No. of live births   x 1000

           Total population

No. of live births (No. of beneficiaries) = 20 x 6000     = 120

                                                                    1000

Pentavalent vaccine given at 6, 10, 14 weeks (3 doses)

No of doses required = No. of beneficiaries x wastage multiplication factor (WMF) x No. of doses

              = 120 x 1.11 x 3 = 399.6

1 vial of pentavalent vaccine contains 10 doses

No. of vials required = (No. of beneficiaries x no. of doses x wastage multiplication factor)/doses per vial.

Therefore no. of pentavalent vials required for one year = 399.6 = 39.96 = 40 vials

                                                                                              10

Expected no of live births (Y) = 20 x 6000     = 120

                                                      1000

             10% of pregnancies are lost as abortions & stillbirths

The total number of expected pregnancies (Z) = Y + 10% of Y

Therefore total no. of expected pregnancies in a year = 120 + 12 = 132
