The UK's first COVID-19 vaccine rollout is taking place. There has been a slight bump in the road after two people reported allergic reactions to the vaccine. The Medicines and Healthcare Products Regulatory Agency (MHRA) said, "Any person with a history of a significant allergic reaction should not receive the Pfizer BioNtech vaccine". On the show, we are joined by Dr Vikram Talaulikar, volunteer, Oxford vaccine human trials.
