EXERCISES ON IMMUNIZATION

Q:The number of infants and pregnant women in a subcenter area was counted during a survey and the following results were obtained:-

No. of infants= 90No. of PW= 52Using the above information calculate the monthly requirement of the subcenter for

a) Vaccine vialsb) Syringesc) Diluentsd) Vitamin A syrup

Step 1: Calculate beneficiary per month

Head count (one year)

Head count (per month)

PW Infants PW(a)

Infants(b)

52X 2= 104 90 104/12=9 90/12 = 8

Step 2 Calculate total number of doses for individual vaccine and vaccine vials

Head count (one year)

Head count (per month)

Total number of doses for TT Vaccine vial

needed

PW Infants PW(a)

Infants(b)

PW X No. of doses for PW + Infants x No. of doses for infants (c)

(c ) x WMF/ no. of doses in a vial

52X 2= 104

90 104/12=9

90/12 = 8

(9X2)+(8X2)=34 34X1.33/10=4.52(5) Tetanus Toxoid

Head count (one year)

Head count (per month)

Total number of doses for BCG Vaccine vial

needed

Infants Infants (a) (a) X No. of doses = (b)

(b ) x WMF/ no. of doses in a vial

90 90/12 = 8 8X1=8 8X1.33/5=2.13 (3) BCG

Head count (one year)

Head count (per month)

Total number of doses for OPV

Vaccine vial needed

Infants Infants (a) (a) X No. of doses= (b)

(b ) x WMF/ no. of doses in a vial

90 90/12 = 8 8x4=32 32x1.33/20=2.13(3) OPV

Head count (one year)

Head count (per month)

Total number of doses for LPV Vaccine vial needed

Infants Infants (a) (a) X No. of doses = (b)

(b ) x WMF/ no. of doses in a vial

90 90/12 = 8 8x3=24 24X1.33/10=3.19 (4)

LPV

Head count (one year)

Head count (per month)

Total number of doses for DPT Vaccine vial

needed

Infants Infants (a) X No. of doses = (b)

(b ) x WMF/ no. of doses in a vial

90 90/12 = 8 8X2=16 16X1.33/10=2.13 (3) DPT

Head count (one year)

Head count (per month)

Total number of doses for measles Vaccine vial needed

Infants Infants (a) (a) X No. of doses (b ) x WMF/ no. of doses in a vial

90 90/12 = 8 8X2=16 16X1.33/5=4.25 (5) MEASLES

Head count (one year)

Head count (per month)

Total amount of Vitamin A (ml) Vitamin A Bottles

needed

Infants Infants

90 90/12 = 8 (8X1X1ml)+(8X2mlX8)=136

136X1.11=150ml(2 bottles)

VITAMIN A

Step 2:Calculate the No. of SyringesFor BCG we need 0.1 ml syringe

No. of BCG injections=8X1.11 (WMF) = 8.88 =9

For TT, LPV, DPT, Measles we need 0.5ml syringeNo. of TT + LPV + DPT + Measles=34+24+16+16=90 x 1.11=99.9=100

For reconstitution (BCG, Measles) we need 5ml syringe=No. of BCG vials+ No. of measles vials=(3+5) X1.11=8.88=9

Step 4: Calculate the diluents required

• Normal saline= No. of BCG vials= 3(ampoules)

Distilled water= No. of measles vials=5(ampoules)
