  2. Along with OPV withdrawal, an appropriate containment of eradicated polioviruses is a key objective of the Polio Eradication and Endgame Strategic Plan 2013-2018. Containment of polioviruses, as laid out in GAPIII, is taking place in 3 phases linked to global milestones in polio eradication. Current (Phase 1) activities are focused on containment of WPV2 and VDPV2, as well as on preparation for containment of vaccine polioviruses of type 2 (OPV/Sabin2). To support this process, WHO/Europe organized a poliovirus biorisk management training course on 17–20 May 2016 in Copenhagen, Denmark for representatives from all 13 Member States in the European Region intending to keep type 2 wild poliovirus (WPV2) or vaccine-derived poliovirus (VDPV2) materials for research or vaccine manufacturing purposes. More information can be found here.
  3. 19 Member States in the WHO European Region were among the 155 countries and territories across the world that stopped using trivalent OPV: http://www.euro.who.int/en/health-topics/communicable-diseases/poliomyelitis/news/news/2016/05/european-region-successfully-withdraws-trivalent-oral-poliomyelitis-polio-vaccine
  4. Science Daily, 20 May: A groundbreaking study shows that a single injectable dose of inactivated polio vaccine (IPV) along with bivalent oral polio vaccine could protect up to 90 percent of children from polio and strengthen community protection against the disease. The research, published in the latest edition of The Lancet, provides the evidence behind the worldwide switch to a new polio vaccine strategy by demonstrating that new schedules of the injectable vaccine with the bivalent oral vaccine protect kids much faster and is safer than using the oral vaccine alone.

  5. Fortune-9 May 2016: Japan’s Takeda Pharmaceuticals is to get $38 million from the Bill & Melinda Gates Foundation to develop a crucial, low-cost polio vaccine for use in developing countries. As part of a global plan to eradicate the crippling disease, of which experts say the world could see the last case this year, countries will need to switch from using oral polio vaccine (OPV) to using so-called inactivated polio vaccine (IPV) to ensure the disease does not reappear. Experts fear a substantial worldwide shortage of IPV once every country in the world is ready to make the switch, and polio eradication strategists have been looking at how to avert that shortfall by encouraging new manufacturers into the sector.

  6. All 19 countries in the WHO European Region that had trivalent OPV (tOPV) in their immunization programmes discontinued this vaccine by the global deadline of 1 May and either introduced bivalent OPV (bOPV) or switched to and inactivated polio vaccine (IPV)-only schedule. The two-week validation period is ongoing, and by 15 May all countries are expected to submit formal validation reports to WHO. The attached map reflects the situation with the tOPV switch in the WHO European Region as of 3 May 2016.

  7. STAT, 2 May 2016 : A two-week campaign to phase out a polio vaccine that is now considered harmful to the effort to eradicate the disease appears to have been completed, polio program leaders at the World Health Organization said Monday. There had been worries that a few countries — China and Russia among them — might not be able to get the job done by May 1. But all 155 nations involved in the unprecedented operation known as “the switch” have complied, director Michel Zaffran told STAT in an interview from Geneva. Read the full article
  8. Reuters, 28 April (Any views expressed in this article are those of the author and not of Thomson Reuters Foundation.): Last week’s launch of the global polio eradication initiative’s “big switch” has garnered wide interest among the public and the media, and rightly so. According to the World Health Organization the simultaneous switch from trivalent to bivalent oral polio vaccine is the largest vaccine rollout in history with 155 countries involved. To complete the goal of ridding the world of polio this should be one of the final pieces in the jigsaw. However, three days after the initiative was launched a less well reported event occurred in Pakistan that serves as a stark reminder of the challenges still remaining. The news of seven policemen being attacked and killed while protecting polio vaccinators on their rounds in Karachi is distressing, but sadly not surprising. Violent, often fatal, attacks in general, as well as specific attacks on polio workers and their security guards, have been a growing phenomenon and challenge to polio eradication.

  9. Between 17 April and 1 May 2016, 155 countries and territories around the world will stop using the trivalent oral polio vaccine (tOPV), which targets all three strains of wild poliovirus, and replace it with bivalent OPV (bOPV), which targets the remaining two wild polio strains, types 1 and 3. See the map and the report
  10. Every country or territory in the world that was using trivalent oral polio vaccine (OPV) (containing all three serotypes of poliovirus) was scheduled to withdraw this vaccine from their immunization programmes and activities on one appointed day in the 2-week period 17 April –1 May 2016. They were to replace the vaccine with bivalent OPV – containing only types 1 and 3 – or move to an immunization schedule with only the inactivated form of polio vaccine (IPV). 19 of these countries are located in the WHO European Region. As of 2 May 2016, 150 of the 155 countries and territories have confirmed that they are no longer using tOPV. See live tracking of switch across the world: http://maps.who.int/OPV_switch/ More information on the switch in the European Region will be posted on this Forum in the coming days.
  11. TIME‎, 27 April 2016 - 'Never before in the history of vaccines have we collaborated on this scale, this quickly' Let’s start simple: Imagine you need to vaccinate a child against a terrible disease. You acquire and administer the correct dosage to protect that child from a debilitating virus. Now, imagine doing that across a whole city. You train health workers, distribute the vaccine to every health facility, explain the process to parents and monitor closely to make sure all children in the city are being reached. Now, do it for a whole district. A whole country. 155 countries. Do all of that in just two weeks. Read the full article
  12. UN Dispatch: Polio is irrelevant in most of the world. Once the terror of many childhoods, for most people it exists only as a name on a vaccine. It’s an infectious viral disease that causes fever, fatigue, headache, vomiting – and sometimes paralysis and death. There is no cure, but it is vaccine-preventable. In fact, since 1988, the polio vaccine has decreased the number of cases by 99% – from about 350,000 cases to 359. Read the full article
  13. The Globe and Mail-22 Apr 2016: In a carefully synchronized move this week, the world’s health workers stopped using their traditional three-strain oral polio vaccine and switched to a simpler and safer two-strain vaccine. It means that the world is one step closer to its first complete eradication of a human disease since smallpox was eliminated in 1980. The co-ordinated switch in 150 countries is being described as the biggest and fastest rollout of a vaccine in history. Experts call it a key element in the “polio endgame strategy” – an endgame that could lead to the eradication of polio worldwide by the end of the decade. “It’s a landmark, a milestone,” said Gregory Agogo, the WHO official who was explaining the switch to the vaccinators at the refugee camp in Maiduguri this week. “But people don’t like to change the status quo, so we need to supervise it.” Read the full article

    Between 17 April and 1 May, every country in the world currently using oral poliovirus vaccine (OPV) must withdraw the trivalent vaccine (tOPV) and replace it with the bivalent vaccine (bOPV). This will continue to protect infants from poliovirus types 1 and 3 while withdrawing the type 2 component, thereby mitigating the risk of seeding new type 2 circulating vaccine-derived poliovirus (cVDPV2).

  15. This series of six videos explain the important steps that are being taken to make sure that, once the poliovirus has been eradicated, it will never have the opportunity to return. We have never been closer to achieving our goal; but there is much still to be done to secure a polio-free world. Once wild polio has been eradicated, the only risks of the virus returning would come from rare strains of circulating vaccine derived polioviruses, and from potential leaks of the virus from laboratories or vaccine manufacturers. This series of videos will explain the work being done to address these risks: from the vaccines that are being used to stop polio; to how the oral polio vaccine is being phased out from April 2016 to remove any risk of vaccine-derived polioviruses, starting with the switch from trivalent to bivalent oral polio vaccine in April 2016; and how securely containing polioviruses within laboratories and vaccine manufacturing sites will keep every last child protected, long into the future.
  16. Two vaccines have brought us to the brink of a polio-free world: the oral polio vaccine and the inactivated polio vaccine. Learn how these vaccines work and the different, complementary roles they have to play in delivering a polio-free world. This is one of a series of six videos on what is being done to secure a polio-free world: from the vaccines that are being used to stop polio; to how the oral polio vaccine is being phased out from April 2016 to remove any risk of vaccine-derived polioviruses, starting with the switch from trivalent to bivalent oral polio vaccine in April 2016; and how securely containing polioviruses within laboratories and vaccine manufacturing sites will keep every last child protected, long into the future.
  17. In order to secure a polio-free world for all future generations, we must eradicate all strains of the virus. Learn about wild polioviruses and vaccine-derived polioviruses, and what needs to be done to stop both strains for good. This is one of a series of six videos on what is being done to secure a polio-free world: from the vaccines that are being used to stop polio; to how the oral polio vaccine is being phased out from April 2016 to remove any risk of vaccine-derived polioviruses, starting with the switch from trivalent to bivalent oral polio vaccine in April 2016; and how securely containing polioviruses within laboratories and vaccine manufacturing sites will keep every last child protected, long into the future.
  18. Learn about the switch from trivalent bivalent oral polio vaccine in April 2016 - the biggest, globally-synchronised project in the history of vaccines - and why gradually phasing out the oral polio vaccine is essential to prevent the emergence of circulating vaccine-derived polioviruses in the future. This is one of a series of six videos on what is being done to secure a polio-free world: from the vaccines that are being used to stop polio; to how the oral polio vaccine is being phased out from April 2016 to remove any risk of vaccine-derived polioviruses, starting with the switch from trivalent to bivalent oral polio vaccine in April 2016; and how securely containing polioviruses within laboratories and vaccine manufacturing sites will keep every last child protected, long into the future.
  19. Learn about the safety nets being put in place to make sure that the phased withdrawal of the oral polio vaccine will speed up our journey towards a polio-free world, such as the introduction of the inactivated polio vaccine into routine immunization programmes. This is one of a series of six videos on what is being done to secure a polio-free world: from the vaccines that are being used to stop polio; to how the oral polio vaccine is being phased out from April 2016 to remove any risk of vaccine-derived polioviruses, starting with the switch from trivalent to bivalent oral polio vaccine in April 2016; and how securely containing polioviruses within laboratories and vaccine manufacturing sites will keep every last child protected, long into the future.
