tOPV- bOPV switch: why?
To secure Polio eradication forever, all live polio virus including vaccine virus have to be removed from population. The “Polio eradication” and endgame strategic plan 2013-2018” mandates that all countries must stop use of oral Polio vaccine beginning with type two component of Trivalent OPV (tOPV). This is planned through a globally synchronized switch from tOPV to bOPV for Routine Immunization and supplementary Immunization activities .

Principle of Switch
  • Successfully recall all tOPV and introduce bOPV in April 2016
  • Minimize tOPV wastage after switch.
  • Avoid tOPV stock outs before and bOPV stock outs after the switch.
  • Validate that tOPV is not available at any service delivery points.

  • Switch preparation: - January to March 2016.
  • National switch date:- 25th April 2016 .
  • tOPV disposal : 25th April to 2nd May 2016.
  • Switch validation:- 26th April to 9th May 2016.
