Arianna Cavalcante, 28, a dental surgeon, a volunteer in COVID-19 vaccine trial for AstraZeneca, poses for a photograph in Sao Paulo, Brazil, December 09, 2020. "I decided to take part in the trials because there was a light at the end of the tunnel for this new disease that scares all of us … I lose patients every day. It's desperate. It's terrifying. So I believe that every opportunity to help is valid," Cavalcante said. "I think that in the future, volunteers will not be remembered. Just like today there are several vaccines and no one remembers the volunteers who ever took part in the tests. But I don't mind, I don't mind not being remembered. I think that having the vaccine and saving people for me is the most important thing." Picture taken with a slow shutter speed. REUTERS/Amanda Perobelli SEARCH "PEROBELLI VACCINE" FOR THIS STORY.

Morgana de Menezes Maia, 24, a dental surgeon, a volunteer in COVID-19 vaccine trial for AstraZeneca, poses for a photograph in Sao Paulo, Brazil, December 09, 2020. "I have been working with COVID-19 patients since the beginning of the year … I've learned how important it is to stay close to our family and people we love – what a difference that makes, both in your personal and professional life. I think I matured during this year. Facing all this has made me more independent. I've always had (my parents) by my side, but I had to face this all alone, at work and everywhere else. I think it was a year that matured a lot," Menezes Maia said. "The hardest part was to face this period without knowing when it is going to be over, without knowing if the vaccine will really be here next year … The pandemic affected the whole world. Everyone felt the effects of quarantine, isolation, the disease. Many people lost their loved ones, friends. Being able to volunteer is unique. There aren't a lot of us who are part of this moment that will be remembered. Picture taken with a slow shutter speed. REUTERS/Amanda Perobelli SEARCH "PEROBELLI VACCINE" FOR THIS STORY.
