Bulletin 101 | Josephine Robertson and Nicola Oliver
With mass COVID-19 vaccination underway across the world, hopes are high for an end to the pandemic. However, it’s not enough for a vaccine to be effective in an clinical trial context. Vaccines can be effective only once they have been administered; and that effectiveness may also differ from that seen in trials.
In this bulletin, we consider what influences people to agree to a vaccine, how this can be understood with reference to diffusion theory, and how the monitoring of real-world effectiveness (likely to differ from that of trials) can help influence people to be vaccinated.
