WHO said Thursday that it has
reached an agreement with Israel for limited pauses in the fighting to allow for the vaccination campaign to take place. Even so, such a large-scale campaign will pose major difficulties in a territory blanketed in rubble, where 90% of Palestinians are displaced.
Where are the vaccines now?
Around 1.3 million doses of the vaccine traveled through the Kerem Shalom checkpoint and are currently being held in “cold-chain storage” in a warehouse in Deir al-Balah. That means the warehouse is able to maintain the correct temperature so the vaccines do not lose their potency.
Another shipment of 400,000 doses is set to be delivered to Gaza soon.
The vaccines will be trucked to distribution sites by a team of over 2,000 medical volunteers, said Ammar Ammar, a spokesperson for UNICEF.
What challenges lie ahead?
Mounting any sort of campaign that requires traversing the Gaza Strip and interacting with its medical system is bound to pose difficulties.
The U.N. estimates that approximately 65% of the total road network in Gaza has been damaged. Nineteen of the strip’s 36 hospitals are out of service.
The north of the territory is cut off from the south, and travel between the two areas has been challenging throughout the war because of Israeli military operations. Aid groups have had to suspend trips due to security concerns, after convoys were targeted by the Israeli military.
Peeperkorn said Friday that WHO cannot do house-to-house vaccinations in Gaza, as they have in other polio campaigns. When asked about the viability of the effort, Peeperkorn said WHO thinks “it is feasible if all the pieces of the puzzle are in place.”
How many doses do children need and what happens if they miss a dose?
The WHO says children typically need about three to four doses of oral polio vaccine — two drops per dose — to be protected against polio. If they don’t receive all of the doses, they are vulnerable to infection.
Doctors have previously found that children who are malnourished or who have other illnesses might need more than 10 doses of the oral polio vaccine to be fully protected.
Are there side effects?
Yes, but they are very rare.
Billions of doses of the oral vaccine have been given to children worldwide and it is safe and effective. But in about 1 in 2.7 million doses, the live virus in the vaccine can paralyze the child who receives the drops.
How did this outbreak in Gaza start?
The polio virus that triggered this latest outbreak is a
mutated virus from an oral polio vaccine. The oral polio vaccine contains weakened live virus and in very rare cases, that virus is shed by those who are vaccinated and can evolve into a new form capable of starting new epidemics.
