Polio Vaccines 2022

Polio is a vaccine-preventable disease, says the U.S. CDC. And 'anyone planning to travel internationally should confirm they are fully vaccinated against polio disease before visiting at-risk countries,' says the World Health Organization (WHO) International Travel and Health vaccine recommendations. 

The WHO confirmed on November 1, 2022, the spread of poliovirus remained a Public Health Emergency of International Concern and recommended the extension of Temporary Recommendations for a further three months

In addition, the WHO says residents (and visitors for more than four weeks) from infected areas should receive an additional dose of oral polio vaccines (OPV) or inactivated polio vaccine (IPV) within four weeks to 12 months of travel. Most countries recommend children get vaccinated against polio early in life. In 2021, more than 372 million children were immunized against polio multiple times in 30 countries, using more than one billion OPVs.

The U.S. CDC confirmed on September 13, 2022, that the U.S. was added to the list of countries for circulating vaccine-derived poliovirus. And the GPEI shared reports on polio eradication and transition at the 75th WHO World Health Assembly in late May 2022. 

Polio Vaccines - USA

The CDC updated the pediatric and adult polio vaccination schedules on February 17, 2022. In addition, various U.S. FDA-approved polio vaccines are listed at PrecisionVaccinations.com/Polio.

WHO Prequalified Polio Vaccine 2022

nOPV2 Polio vaccine is derived from the live, infectious virus. It has been 'triple-locked using genetic engineering to prevent it from becoming harmful. The nOPV2 vaccine is not available in the U.S.

Eupolio is the first Sabin-IPV to obtain WHO prequalification. The main advantage of using attenuated Sabin poliovirus strains in IPV production is a lower biosafety risk than wild-type polioviruses used to manufacture conventional IPVs.

SINOVAC's sIPV polio vaccine is approved for infants and children aged two months and older to prevent poliomyelitis from infection of types I, II, and III polioviruses.

Polio Vaccinations U.K.

The U.K. Health Services Agency published on November 14, 2022, immediate actions in response to the detection of a VDPV2 in London sewage samples. Primary care colleagues and immunization providers should opportunistically check that patients are up to date with their polio-containing vaccines and provide catch-up vaccination to anyone who is un/under-vaccinated. In London, an Inactivated Polio Vaccine Booster campaign has been launched targeting children aged 1 to 9 years of age.

The polio vaccine is part of the NHS childhood vaccination schedule. It's given when children are 8, 12, and 16 weeks old as part of the 6-in-1 vaccine; then at three years and four months old as part of the 4-in-1 (DTaP/IPV) pre-school booster, and at 14 years old as part of the 3-in-1 (Td/IPV) teenage booster. In the U.K., children need to have all of these vaccinations to be fully vaccinated against polio.

The WHO formally confirmed on September 14, 2022, that the UK has a ‘circulating’ VDPV2 based on the detection of the same isolate for more than 60 days and evidence that the virus detected in London is genetically linked to the poliovirus detected in Israel and the U.S.

Polio Vaccinations Israel

In July 2022, Dr. Sharon Alroy-Preis, the Health Ministry's public health chief, stated to the JPost, 'no poliovirus was found in the country's sewage in July 2022.' However, in 2013-2014, Israel detected WPV1 in wastewater samples in its southern regions. And peer-review journal The Lancet reported that between 2005 and 2013, Israel discontinued the administration of the live polio vaccine.

Polio Travel Alerts

On November 18, 2022, the CDC's Alert - Level 2, Practice Enhanced Precautions travel advisory stated that anyone unvaccinated, incompletely vaccinated, or with an unknown polio vaccination status should complete the routine polio vaccine series before any international travel. And the Pan America Health Organization (PAHO) confirmed on September 21, 2022, vaccination coverage has fallen below 80% in nearly all of South America, and 12 countries (Brazil) in the region are at High or Very High risk of experiencing a polio outbreak.

Polio Outbreaks

Poliovirus has been around since ancient times. The virus lives in an infected person's throat and intestines and spreads through person-to-person contact and other means. Countries infected with WPV1, cVDPV1, or cVDPV3, with the potential risk of international spread, include Afghanistan, Pakistan, and Malawi (WPV1), China (cVDPV3), Madagascar (cVDPV1), and Yemen (cVDPV1). The health authorities in Malawi declared an outbreak of wild poliovirus type 1 on February 17, 2022, and Pakistan launched its investigations on April 22, 2022. 

And the International Health Regulations National Focal Point for Israel notified WHO of the detection of cVDPV3 in the country on March 7, 2022. And the European CDC recently reported VDPV2 isolates found in the U.K. were genetically linked to VDPV2 isolated from a polio case that had been reported in July 2022 from New York, as well as to environmental samples collected in New York and greater Jerusalem, Israel.

 

Poliomyelitis Overview

Poliomyelitis (polio) is a highly infectious viral disease that primarily affects children five years and under. There are three strains of wild poliovirus (type 1, type 2, and type 3). In the USA, all infants and children should receive four doses of IPV at ages 2, 4, 6–18 months, and 4–6 years. The first dose may be given as early as six weeks of age. The final dose should be administered at four years or older, regardless of the number of previous doses, and should be given six months or more after the last dose. A fourth dose in the routine IPV series is unnecessary if the third dose was given at four years or older and six months or more after the previous dose.
