New Global Reviews Confirm HPV Vaccine Strongly Reduces Cervical Cancer Risk With No Serious Side Effects
Studies show girls vaccinated by age 16 face dramatically lower cervical cancer risk with no major side effects. Two major international reviews have reaffirmed that the human papillomavirus (HPV) vaccine is highly effective in preventing cervical cancer, offering one of the clearest assessments to date of its long-term benefits and safety. The impact of the slowdown in major global economies will be “smaller” on the UAE’s growth and exports due to its relatively less exposure to those markets compared to other markets across the region, the World Bank said.
The Cochrane reviews, released this week, analysed data from clinical trials and real-world research involving more than 132 million people worldwide. The findings show that girls aged 16 or younger who received the HPV vaccine were 80 per cent less likely to develop cervical cancer compared to unvaccinated peers. The jab also significantly reduced precancerous cervical changes, with the strongest protection observed when individuals received the vaccine before any exposure to the virus.
“We now have clear and consistent evidence from around the world that HPV vaccination prevents cervical cancer,” said Nicholas Henschke, one of the review authors and head of Cochrane Response.
HPV is a widespread family of viruses, most of which are harmless, but several strains are known to cause cancers of the cervix, anus, penis, vulva, vagina, mouth and throat. According to the World Health Organization, cervical cancer remains one of the most common cancers in women, with about 660,000 new cases and an estimated 350,000 deaths recorded globally in 2022.
While vaccines such as Cervarix and Gardasil have long been recognised as major medical advances, they have also been at the centre of controversy. In recent years, Merck & Co., the manufacturer of Gardasil, has faced lawsuits alleging health complications linked to the vaccine. A US judge dismissed the claims earlier this year, calling them speculative and unsupported by evidence.
Cochrane’s review assessed both minor and serious side effects reported in vaccine recipients. The researchers found that common reactions—such as temporary soreness in the arm—were mild and short-lived. After comparing safety reports with real-world follow-up data, the team found no evidence that HPV vaccination increases the risk of severe medical problems. Serious health issues were recorded at similar rates in both vaccinated and unvaccinated groups.
“An important finding was that the commonly reported side effects of the vaccine, often discussed on social media, were found to hold no evidence of a real link to vaccination,” Henschke said.
The results support ongoing global guidance to vaccinate both girls and boys ideally before they turn 16, when protection is strongest. Dr Jo Morrison, a gynaecological oncologist and co-author of the review, said vaccinating boys helps strengthen community-wide protection and is expected to reduce cancers affecting men later in life.
While most existing studies come from high-income countries, researchers say more data from lower-income regions is needed, especially in areas with the highest cervical cancer rates. Scientists expect clearer evidence in the years ahead as long-term monitoring continues.
“It will take decades to fully understand the impact of vaccination,” Morrison added, noting that the early findings already point to a significant reduction in future cancer cases.

Global Mental Health Cases Near 1.2 Billion as Anxiety and Depression Drive Sharp Worldwide Rise
A major global analysis has found that mental health conditions have surged to an estimated 1.2 billion people worldwide, driven largely by steep increases in anxiety and depression over the past three decades.
The findings, published in The Lancet as part of the Global Burden of Disease Study 2023, show that the number of people living with mental disorders has almost doubled since 1990, marking a 95% rise. Researchers say major depressive disorder and anxiety disorders have seen even sharper growth, increasing by 131% and 158% respectively, making them the most prevalent mental health conditions globally.
The report describes mental illnesses as widespread conditions that create long-term disability and significant human suffering. It also highlights broader consequences for economies and public services, including reduced productivity, lower workforce participation and increasing pressure on health and welfare systems.
Researchers estimate that in 2023 alone, around 620 million females and 552 million males were affected by mental health conditions. While the overall burden is rising across both sexes, the study points to notable differences in the types and prevalence of disorders.
Among women, depression and anxiety were the most commonly reported conditions, alongside higher rates of eating disorders such as anorexia nervosa and bulimia nervosa. The report links this disparity to a mix of biological, social and structural factors, including exposure to domestic violence, sexual abuse, gender inequality and reproductive health-related changes.
In contrast, neurodevelopmental and behavioural disorders, including attention deficit hyperactivity disorder (ADHD), conduct disorder and autism spectrum conditions, were more frequently diagnosed in men.
Teenagers aged 15 to 19 were identified as the group experiencing the highest mental health burden globally, raising concerns about early onset of conditions and insufficient preventive care for young people.
The study identifies several key risk factors associated with mental illness, including childhood sexual violence, bullying and intimate partner violence. These factors are strongly linked to conditions such as depression, schizophrenia, bipolar disorder and anxiety disorders. However, researchers note that such exposures have remained relatively stable over time and account for only a portion of the overall rise.
According to the authors, broader drivers are likely contributing to the increasing prevalence of mental disorders. These include genetic and biological influences, poverty, inequality, and the growing impact of global crises such as armed conflict, pandemics, natural disasters and climate-related stress.
While mental health conditions have long been a leading cause of disability worldwide, the report warns that the situation is worsening. At the same time, health systems have not expanded services at a pace matching demand.
The authors caution that the gap between rising need and limited access to care is becoming more pronounced, leaving millions without adequate treatment or support.
