LONDON: Confidence in vaccines – one of the most effective and widely used medical products in the world – is highest in poorer countries, but weakest in wealthier countries, where skepticism has caused the persistence of diseases such as measles, as a global one Study revealed Wednesday (June 19).
France has the least confidence of any country in the safety and efficacy of vaccines. One-third believe that vaccines are uncertain according to the study.
While most parents choose to vaccinate their children, varying degrees of confidence expose the vulnerabilities in some countries to potential outbreaks. The authors of the study recommended that scientists ensure that people have access to reliable information from those they trust.

Public Health experts and the World Health Organization (WHO) claim to have vaccinations Every year, Nes save up to 3 million lives worldwide, and decades of research show that they are safe and effective.
However, to achieve "herd immunity" to protect whole populations, vaccination coverage generally needs to be above 90% or more, 95%, and distrust of vaccines can quickly reduce that protection.
"Vaccines have caused many devastating infectious diseases to be forgotten in the last century," said Charlie Weller, head of vaccines at The Wellcome Trust, which oversaw the Wellcome Global Monitor study.
"It is reassuring that almost all parents worldwide vaccinate their children, but there is less confidence in vaccines all over the world."

The spread of measles, even in major outbreaks in the US and the Philippines and Ukraine, is just one of the health risks associated with lower confidence in vaccines.
In Afghanistan and Pakistan, false rumors about polio vaccines that are part of a Western conspiracy have hampered global efforts to eradicate debilitating disease in recent years.
The survey, conducted by Wellcome and the pollster Gallup, involved 140,000 people from more than 140 countries.
6 percent of parents worldwide – equivalent to 188 million – said that their children are not vaccinated The highest total was 9 percent in China, 8 percent in Austria and 7 percent in Japan.

The study also found that th More and more people in the world trust doctors and nurses than anyone else on health counseling. In most parts of the world, more education and greater trust in health systems, governments and scientists is a sign of greater confidence in vaccines.  However, trust is weaker in some high-income regions. Only 72 percent of people in North America and 73 percent in Northern Europe agree that vaccines are safe. In Eastern Europe it is only 50 percent.
Heidi Larson, head of the immunization project at the London School of Hygiene and Tropical Medicine, worked with researchers on this study. She said it "exposes the paradox of Europe," which, while being the region with the highest income and education levels, also shows the highest vaccine skepticism in the world.
In poorer regions, the level of trust tends to be much higher. 95 percent in South Asia and 92 percent in East Africa are confident that vaccines are safe and effective.
