Vaccines have saved millions of lives. WHO research estimates COVID-19 vaccines prevented 475,000 deaths in the UK alone. Initially hailed as a "scientific miracle," vaccines helped the world return to normal, but public trust has since declined. A study by the Vaccine Confidence Project found that UK adults' belief in vaccine safety dropped from 90% in 2018 to 70% in 2023. This decline is global, with surveys in 52 out of 55 countries showing reduced trust since 2019. A YouGov poll found that in 2024, 30% of UK adults believed vaccine risks were hidden, up from 19% in 2019. Childhood vaccination rates have also fallen below recommended levels. Growing skepticism toward governments and health institutions has contributed to this trend. During the early vaccine rollout, people showed great enthusiasm for getting vaccinated, but by mid-2021, doubts arose, fueled by misinformation online. Research from the UK Health Security Agency (UKHSA) revealed that in 2023, 20% of parents encountered online information that made them doubt vaccines, a significant increase from 6% the previous year. Vaccine hesitancy is not new. Since Edward Jenner's smallpox vaccine in 1796, concerns have persisted. Protests against mandatory vaccinations occurred in the 1890s, and the 1970s saw false claims linking the diphtheria, tetanus, and whooping cough vaccine to brain damage. Social media has amplified misinformation about vaccines, making it easier for false claims to spread quickly. Younger adults, who frequently rely on social media for health information, are particularly affected. Many of them feel that they sacrificed their education, job opportunities, and social lives during the pandemic to protect older generations, which may contribute to their declining trust in vaccines. Another factor influencing public confidence is the speed at which COVID-19 vaccines were developed. Although they proved highly effective at reducing severe illness and death, early expectations suggested they would also prevent infection completely. Over time, as waning immunity and virus mutations occurred, some people felt misled. Concerns also arose regarding rare but serious side effects, such as blood clotting and temporary heart inflammation. Vaccine hesitancy is also linked to broader political and social issues. Discussions about personal liberty, government control, and scientific authority have contributed to public doubts. The rise of anti-establishment movements and skepticism toward experts in fields like climate change, public health, and economics further complicates the issue.

關鍵數據的檢索與運算
這題的核心在於找出文中提到「隱瞞疫苗風險（vaccine risks were hidden）」的具體百分比變化。根據文章第二段的敘述，2024 年有 30% 的英國成年人持有此觀點，而這個數字是從 2019 年的 19% 攀升而來的。題目要求計算的是這段期間的「增加幅度」，因此我們需要將兩個數值相減：
