Recently a study has been conducted to examine the vaccine acceptance and hesitancy rates in ten low and middle-income countries from Asia, Africa, and South America.
The research of the study has been published in the Nature Medicine that reveals the willingness to get a COVID-19 vaccine was considerably higher in developing countries (80 per cent of respondents) than in the United States (65 per cent) and Russia (30 per cent).
The study surveyed over 20,000 respondents for the hesitancy in a broad selection of low- and-middle income countries (LMIC), and bringing together researchers from over 30 institutions including the International Growth Centre (IGC), Innovations for Poverty Action (IPA), WZB Berlin Social Science Center, the Yale Institute for Global Health, the Yale Research Initiative on Innovation and Scale (Y-RISE), and HSE University (Moscow, Russia).
When vaccine shipments are still slow to arrive to the majority of the world’s population, the study comes at a critical crisis and coronavirus cases are increasing in many parts of Africa, Asia, and Latin America. The findings suggest that prioritizing vaccine distribution to low- and middle-income countries should yield high returns in expanding global immunization coverage.
Personal protection against COVID-19 was the main reason given for vaccine acceptance among LMIC respondents (91 per cent), and concern about side effects (44 per cent) was the most common reason for vaccine hesitancy. Health workers were considered the most trusted sources of information about COVID-19 vaccines.
“As COVID-19 vaccine supplies trickle into developing countries, the next few months will be key for governments and international organizations to focus on designing and implementing effective vaccine uptake programs,” said Niccolo Meriggi, Country Economist for IGC Sierra Leone and study co-author. “Governments can use this evidence to develop communications campaigns and systems to ensure that those who intend to get a vaccine actually follow through.”
The researchers, who conducted the surveys between June 2020 and January 2021, point out that vaccine acceptance may vary with time and with the information that people have available to them. While the evidence on the safety and efficacy of available COVID-19 vaccines has become clearer in the last six months, severe, but rare, side effects may have undermined public confidence.
Saad Omer, Director of the Yale Institute of Global Health and study co-author, said: “What we’ve seen in Europe, the US, and other countries suggests that vaccine hesitancy can complicate policy decisions, thereby hindering rapid and widespread vaccine uptake. Governments in developing countries can start engaging trusted people like health workers now to deliver vaccine messaging about side effects that are accurate, balanced, and easily available to the public.”
Alexandra Scacco, Senior Research Fellow at the WZB and study co-author said, “Across countries, we observe that acceptance of COVID-19 vaccines is generally somewhat lower than for other vaccines, perhaps because of their novelty. However, the consistently pro-vaccine attitudes we see in low and middle-income countries give us reason to be optimistic about uptake.” “We hope that evidence from our study can help inform strategies to expand global COVID-19 vaccination.”
