- Liberia and Africa were officially certified as free from Wild Polio Virus (WPV) in August 2020 by WHO, an incredible milestone in global polio eradication campaign
- In 2021 another type of polio virus called cVDPV (Circulating Vaccine-Derived Polio Virus) is causing polio outbreaks in 18 countries of Africa
- As of January 2021, all three countries bordering Liberia – Cote d’Ivoire, Sierra Leone and Guinea – have reported polio outbreaks and over 100 children being paralyzed for life
- Laboratory tests of environmental samples have already confirmed the presence of cVDPV type of polio virus circulating in Monrovia in December 2020
- Liberia is at an immediate risk of a cVDPV polio outbreak and Liberian children are at an urgent risk of contracting this incurable disease
Polio in the World
- COVID-19 pandemic has disrupted immunization around the world, including Liberia. From March to July 2020, 60 polio vaccination campaigns in 28 countries were suspended
- Polio campaigns were suspended to protect communities and staff from COVID-19 impacting polio eradication efforts and increasing transmission of the disease
- Rumors and misconceptions surrounding all vaccines, including Covid, have spread vaccine hesitancy globally including in Liberia with refusals noted among some communities
- Africa is most seriously affected, but cVDPV outbreaks are also ongoing in the Middle East and Southeast Asia
- In 2020 globally, over 900 polio cases were reported which is a substantial increase from 249 cases reported in 2019.
- Polio is one of the only three diseases classified as a public health emergency of international concern along with Ebola and COVID-19 pandemic. Detection of polio is a Public Health Emergency in any country, including Liberia.
Action in Liberia
- Based on laboratory results confirming the circulation of cVDPV polio virus in Liberia, the Government of Liberia has declared a Public Health Emergency for cVDPV polio outbreak
- With support from the Global Polio Eradication Initiative (GPEI), which includes WHO, UNICEF, GAVI, CDC and Rotary, the Ministry of Health plans to conduct two rounds of house-to-house polio nationwide campaign with an aim of vaccinating at least 95% children aged 0-5 years while observing COVID19 protocols to ensure vaccinators, health workers and communities adhere to COVID19 precautions and are protected from COVID19.
- With support from partners, the Ministry of Health will conduct trainings for vaccinators and other health workers on polio immunization and COVID19 precautions such as wearing of masks, keeping a safe distance and frequent handwashing with soap and clean water. In addition, personal protective equipment such as masks will be provided to all health workers participating in the polio campaign
- To better address ongoing outbreaks of type 2 cVDPV, as recommended by WHO, the Ministry of Health plans to deploy an additional outbreak response tool, the novel oral polio vaccine (nOPV2), which is clinically proven to reduce the risk of cVDPV and is specifically designed to protect children from the only type of poliovirus that remains in Liberia

Polio Frequently Asked Questions
1. What is Polio?
Poliomyelitis (polio) is a highly infectious disease caused by poliovirus, a virus which affects mostly children under the ages of 5. It has no cure, causes lifelong paralysis in children, and in some cases, it can cause death. The only way to protect children is to give them two drops of the oral polio vaccine.
2. Liberia and Africa in general was recently declared polio free, can you explain why we have an outbreak in the country despite the polio free certification?
There are two types of polio, the wild polio virus (WPV) and vaccine-derived polio (cVDPV). Africa and Liberia eradicated WPV type of polio, WPV remains only in Afghanistan and Pakistan. Liberia currently has an active outbreak with cVDPV virus confirmed in Monrovia, and over 100 cases confirmed in neighboring countries such as Guinea, Sierra Leone and Côte d’Ivoire.
cVDPV polio outbreaks occur when the weakened strain of the polio virus contained in the Oral Polio Vaccine (OPV) circulates in under-immunized communities for a long time. While Liberia has been declared free from WPV, a lot of children remain at risk of cVDPV type of polio due to the low immunization rates in Liberia and the neighboring countries.
3. Why are we reporting cases of the vaccine-derived polio in Liberia?
Vaccine-derived polio (cVDPV) continues to circulate due to the low routine and polio immunization vaccination rates in Liberia and other countries. The COVID-19 pandemic has worsened the already low routine and supplementary polio immunizations rates in the country as most activities were put on hold.
Many parents and caregivers did not immunize their children for fear of leaving their houses due to COVID-19. Rumors and misconceptions around vaccines especially Covid Vaccine created fear in communities hence people did not immunize their children.
The outbreak can also be attributed to importation from neighboring countries and poor hygiene and sanitation in the country. Liberia is amongst 18 African countries that have reported cVDPV polio outbreaks in 2021.
4. How is cVDPV polio transmitted?
cVDPV is transmitted through the oral-fecal route from one person to another. The weakened virus is excreted through feces after a child is vaccinated and could easily spread in places with poor hygiene, sanitation, open defecation and overcrowding. This weakened virus can also transmit when water, food or fingers get contaminated by stool containing the weakened virus.
5. Who is at risk of contracting polio?
Due to the low immunization rates in the country, all children aged below 5 years are at high risk especially unvaccinated children or children with low immunity. The best protection against polio is ensuring all children are vaccinated during routine and supplementary immunization campaigns. If a child is optimally immunized with polio vaccines, he/she will be protected from both all types of polio.
6. Why is it important to immunize children again and again with the polio vaccine?
Oral Polio Vaccine (OPV) requires multiple doses to achieve complete immunity in the child and ensure the child’s full protection from polio. Receiving multiple dozes of the polio vaccine poses no harm to your child and is completely safe for children.
7. Will the Ministry of Health use the same vaccine that is causing the polio outbreak to stop the outbreak?
With recommendation from WHO, the Ministry of Health plans to use nOPV2 polio vaccine to stop the polio outbreak. This vaccine is clinically proven to be safe and more effective at reducing the risk of cVDPV.
8. How do we know the vaccine against polio is safe?
Polio vaccine is the safest way to protect children from the remaining type of polio. Polio vaccine in Liberia is pre-qualified by the World Health Organization (WHO) to ensure safety and effectiveness. The vaccines are supplied through UNICEF nationwide for both routine immunization and during immunization campaigns.
Polio vaccine is safe even if the child is suffering from fever, cough, or diarrhea, and is also safe for newborns as young as a few hours old. Polio vaccine has little to no side effects and can be safely given to children multiple times. Countries like the United States, United Kingdom and France used polio vaccine to eradicate polio and protected millions of children from paralysis.
9. How does the Ministry of Health plan to vaccinate all eligible children in the country?
Through two rounds of house-to-house polio campaigns throughout the country, the MoH plans to vaccinate 95% children aged 0-5 years while strictly observing COVID19 protocols to ensure children, vaccinators, health workers and communities are protected.
11. How will the ministry ensure safety of community, health workers and children from COVID19 during the house-to-house polio campaign?
All vaccinators and health workers who will be engaged in the polio vaccination campaign will strictly adhere to the COVID19 protocols by wearing masks, keeping a safe distance while in the communities and frequently washing hands with soap and water.
Ministry of Health also urges the public to adhere to all COVID-19 protective measures and support health workers by presenting all children under the ages of 5 for vaccination whenever a polio team arrives.
12. What impact do COVID-19, rumors, misconceptions and disinformation have on the polio campaigns?
COVID-19 rumors and misconceptions have affected routine immunization services as well as polio campaigns all over the world, including in Liberia. Restrictions of movements due to COVID-19 and dissemination of false information regarding vaccines are some of the reasons that we currently have an outbreak in Liberia.
The Ministry of Health would like to reiterate that the polio vaccine is safe and has been used to avert paralysis in millions of children globally. The Ministry would also like to urge to the public to desist from spreading false information and encourages health workers, community influencers, the media and health experts to counter rumors by providing accurate information to the public.
12. What is nOPV2 and why is it being used?
nOPV2 is a type of polio vaccine that has been in development for over 10 years and has been thoroughly tested in adults, children and infants across multiple countries. It has been declared safe and effective by the Ministry of Health and is recommended for use in polio outbreaks by WHO around the world. It is the most recommended vaccine to control the remaining type of polio virus that is still circulating in Liberia. It is given as 2 drops in a child’s mouth and protects children from polio virus. It can be safely given multiple times to all children under the ages of 5, including newborns or children who have fever, diarrhea, or cough.
