Dr Meenal Viz & Dr Nishant Joshi

Dr Meenal Viz, Dr Nishant Joshi and baby Radhika are the Joshi trio who have been campaigning for healthcare workers throughout the pandemic. Last year, during the first wave of the pandemic, Dr Meenal Viz was the pregnant protester outside Downing Street when Radhika was a foetus. The protest gained worldwide media attention and now Meenal and Nishant hope to use their platform to spread positivity, hope, and help clear any misunderstandings around the vaccine. Changing the world one TikTok at a time!

Nishant works in General Practice and has played a big role in working with local communities to start important dialogue around the vaccines. He has seen the impact of the virus on ethnic minority groups and has been working closely with community leaders to share informed messages around the vaccine. Meenal has been working from home with Radhika, focusing on campaigns to help inform women who are either pregnant, planning to be pregnant, or breastfeeding to make informed choices around the vaccine.

Outside of work, Nishant is a bassist and writes songs about social injustice with his band, The Palpitations (and Baby Radhika is Nishant’s biggest fan). While Meenal has her own podcast, ‘Meenal’s World’, where she interviews trailblazers every week and hopes to educate and empower women across the world.
