Decrease in the level of child immunization in most parts of Africa

Madrid, April 15 (Europa Press) –

In particular, low-income and middle-income countries in Africa have lowered the level of childhood immunization, so Southampton University (UK) needs a more effective childhood vaccination strategy to eliminate vaccine-preventable disease threats.

Geographers who conducted this study in the Communicator of Nature found diphtheria, tetanus and pertussis vaccination rates in Nigeria, Democratic Republic of the Congo, Ethiopia, Mozambique, Cambodia and Southeast Asia, It is less than 80% recommended by the WHO. This means that the likelihood of circulation and disease in these countries is still high.

Using data from demographics and health surveys conducted between 2011 and 2016, the researchers demonstrated the ability to perform routine immunization (IR) by administering three doses of diphtheria-tetanus-pertussis (DTP1-3) I investigated. Up to 5 years, including drop-out rate of dose.

They compared this with the administration of measles-containing vaccine (VMC), and additional immunization (SIA) activities have often been performed. This comparison produced a detailed map (1 square kilometer) showing the coverage of each country's vaccine and reflecting the relative performance of routine and complementary activities.

The map suggests that the first dose of DTP vaccine is significantly different in the Democratic Republic of the Congo, Nigeria, and Ethiopia, suggesting poor access to routine immunizations. However, when the recurring SIA campaign supported the routine management of measles vaccines in the same country, coverage rates were significantly higher.

By contrast, Mozambique and Cambodia have done little to campaign and have not seen any substantial improvement.

The results suggest that additional target campaigns can make a big difference in providing immunization services, particularly in areas where there is little scope for routine immunization, researchers say.

Dr Edson Utazi, Ph.D., a senior researcher with the study, said: "Many things can lead to low levels of vaccination, such as poor access to health care, poor education, low vaccines and even vaccine rejection. These activities can help solve these problems, increase immunization and improve disease resistance. "

In addition, the success of the vaccine administration strategy for doctors is to "ensure a good geographical distribution, as well as ensure that the population's disease range is high enough to prevent spread of the disease."

The researchers are now looking to expand into other countries and develop additional therapies that integrate data on the behavior they want to seek treatment, time to health centers, and the extent of the mobile phone network. They hope that this can lead to the design and implementation of a personalized vaccine management program.
