A rare case on the eve of the start of the polio vaccination campaign in children:
a child from Beit Shemesh who was vaccinated as required for his age with a drop vaccine and a shot vaccine was found in blue stool tests "on high suspicion."
The discovery means that the virus is in the child's gut, but he has no symptoms and the vaccine in the injection he received protects him from paralysis.
The unusual case was discussed this week at a meeting of the Ministry of Health's advisory committee on polio, headed by Prof. Manfred Green, along with updates ahead of the pediatric polio vaccination campaign.
To date, one case of a 4-year-old girl with polio has been discovered, along with 8 cases of morbidity detected in stool tests, with the children themselves asymptomatic.
7 children were not vaccinated, one was partially vaccinated and one was fully vaccinated.
"It is very rare to find a polio virus in the gut of a fully vaccinated child. We would expect such a thing not to happen, but here and there something like this is found," says Prof. Tzachi Grossman, Maccabi chairman of the Pediatrics Association and a member of the committee. Protection of the killed vaccine, in terms of its personal protection is completely protected from paralysis.
Such a case proves to us that the virus is spreading.
The solution to this is to 'flood' the digestive system of children with an attenuated live virus that will prevent such incidents and then the incidence of such a scenario will be reduced to zero. "
Prof. Nadav Davidovich, Chairman of the Public Health Forum: “The chance of a child being fully vaccinated to be positive on a stool test is a fraction of a percent, less than one percent.
This does not mean that the 'vaccine has failed' because there is no 100% protection.
"Unlike Corona, the strategy in polio is to reach a state of 0 cases at the world level and that is the goal of the vaccine perfection we are giving now."
Polio vaccine,
At the beginning of the week, about half a million additional doses of the polio virus (polio) landed in Israel for the purpose of expanding the 'two drops' vaccination campaign throughout the country.
In the coming week, about two million more vaccine doses will arrive.
The vaccination campaign is currently taking place in Jerusalem, and as part of it, more than 23,000 vaccine doses have been given so far and it is expected to expand to the rest of the country.
The campaign focuses on supplementing the vaccine by injection for those who have not yet been vaccinated, along with the supplementation of the vaccine in drops, especially for children aged 9 to 17 (born in 2005-2013) who did not receive two doses of vaccine in drops as part of routine vaccinations.
The Ministry of Health said in a response: "Immunization according to the vaccination routine protects against polio, and in the vast majority of cases also against the continued spread of the virus in the feces. Like any other vaccine or drug, immunity is not 100% but very close. , The secretion is for a short period and in a small amount and therefore the risk of infecting the environment is very small.
It is therefore important to adhere to the vaccination routine in full, a child who has been vaccinated with only one dose of attenuated live vaccine should complete the second dose.
In addition, it is of utmost importance to increase the immunization rate in the population to prevent the polio virus from continuing to spread in unvaccinated populations or with immunosuppression.
"Monitoring in the sewage system is the virus in Jerusalem, Beit Shemesh, Bnei Brak, Tiberias and other localities."
