Metong Daniel

Deputy Director of Public Policy

I am a public health Nurse and WHO trained Infodemic Manager from Rivers State, Nigeria. I hold a Bachelor of Nursing Science and Post Graduate Diplomas in Midwifery and Public Health from the University of Port Harcourt, Nigeria with about 5years post qualification experience. I currently work as the Deputy Director of Public Policy at GIANT (Global Immunization Action Network Team), a Senior Nursing Officer at the University of Port Harcourt Teaching hospital and the Chief Operations Officer of Science Squad Africa (a not-for-profit organization focused on helping young Africans understand and love science and research).

After graduating from the University, I served as a National Corper in the North-Eastern part of Nigeria where I worked passionately in both my place of primary assignment and humanitarian assignments with the Red Cross and MSF despite the volatile security conditions. At the end of my service year, I earned the award of the Most Indigenous Corper of the Year as I had become so well known among the locals that most persons knew me by name or description, and I had learned the main language of the people (Hausa). Since then, I have worked in a variety of settings; the public, private and non-governmental health sectors of Nigeria but I am most enthusiastic about my path for building a career in public health and hope to attain an MPH soon. My love for public health grew after I saw how difficult it was for most people to access their fundamental necessities of life and just how much a small act of kindness could improve people’s living conditions.

I am passionate about contributing my quota to achieving universal access to primary health care, reducing vaccine hesitancy, and increasing vaccine equity through advocacy for health-friendly policies. In my free time, I love to travel, play board games, cook, read, dance, and author medical articles for blogs.

I have always had a passion for health education with a focus on prevention and health promotion. I am currently a student at the University of San Francisco, where I am completing my Master of Public Health degree with a specialization in Community and Public Health Practice. I also hold a Bachelor of Health Sciences degree, with a concentration in Community Health Education from California State East Bay. As an undergraduate I worked as a Peer Advocate for Wellness (PAWS), where I organized programs for the Sexual Health Track within the Student Health Services Center. I also developed the curriculum for the “Sexual Health Condom Cart. This roving campus cart provided sexual health information to student in an easy-to-understand format. I was also instrumental in developing interactive games and interventions for student health fairs that were held on campus twice a year.

I have held many administrative positions within healthcare and human resources. My most recent position was working with Alameda County managing the COVID-19 response. Throughout my experiences in school and life, I have learned that public health professionals play a key role in preventing and combating disease within populations. As a current participant in the 3rd World Health Organization’s (WHO) Infodemic Manager Training class, I now realized that public health professional can also play a role in preventing the spread of misinformation and disinformation regarding immunizations and attitudes with vaccine hesitancy. I feel passionate that vaccine hesitancy and promotion of health literacy needs to be addressed not only to bring this COVID-19 pandemic under control, but to make sure we are better prepared as a worldwide community to address the next global pandemic and beyond. I plan to use the knowledge gain from my experience with the Global Immunization Action Network Team (GIANT) and WHO Infodemic Manger Training to increase global awareness, promote health literacy and strength healthy behaviors that will guarantee more communities are made aware of the importance of immunization, and scientifically researched and accurate health information.

In my free time I am enjoying traveling, reading, cooking, and spending time with family and friends.
