This portrait series, to which I keep adding photos, is a tribute to health workers around the world who tirelessly strive to save lives and make the world a better place.

“My job is to ensure that everyone understands why vaccines are so important. The relationship of trust is essential, particularly for community health workers.”

Shabnoor was born in the refugee camps of Cox’s Bazar, Bangladesh. Today, she is a community health worker who goes door to door to identify unvaccinated children and provide parents with information about vaccines.

“Vaccines help prevent diseases, and they save many lives. I became a health worker to help people stay healthy and find peace.”

Sonia works at a primary health care centre in Cox’s Bazar, Bangladesh. She provides vaccines and other health services to Rohingya refugees sheltering there. She became a health worker because she wanted to put her skills to good use.

“When I started working in Nampula province, many parents refused to vaccinate their children. They thought that the cholera vaccine we were giving them was actually the cause of the disease. It was really hard work to make parents understand that the vaccine helps to keep their families healthy. Together with religious leaders, we organised information sessions to dispel rumours.”

Etelvina comes from Maputo, Mozambique. For ten years, she has worked as a community health worker, bringing vaccines to people living in hard-to-reach areas of the country.

“We start the immunisation session at 07:00 and continue until at least 15:30, but we don’t finish until the last person in line has been vaccinated. Many mothers rush here during their lunch break to bring their children as they cannot afford to skip work.”

Marta leads a team at the immunisation ward of Centro de Saúde do Alto Maé in Maputo. She always dreamt of becoming a health worker, like her mother before her.

“Parents who don’t come to the health centre often live too far away, lack the means of transport, or are not yet familiar with the importance of vaccines. We identify zero-dose children through the door-to-door visits that community health workers conduct. Each time we identify a child, I feel proud and happy because it allows us to reach our target population.”

Boubacar Rachida is a vaccinator at CSI Madina, a health centre in Niamey, Niger.

“If a woman in the community is pregnant, or if there is a childbirth, I will reach out and explain why vaccines are so important. I will follow up three to four months later and ask if there are children who have not yet been vaccinated.”
