This Week in Microbiology is a podcast about unseen life on Earth hosted by Vincent Racaniello and friends. Following in the path of his successful shows 'This Week in Virology' (TWiV) and 'This Week in Parasitism' (TWiP), Racaniello and guests produce an informal yet informative conversation about microbes which is accessible to everyone, no matter what their science background.

Scientists have produced effective vaccines against SARS-CoV-2, the virus causing the worldwide pandemic of COVID-19. The speed with which the vaccines were produced is unprecedented, and that makes some worry that they were “rushed through” and may not be safe or effective.
