Why Hancock Bet the Exit Strategy on Vaccines
Hancock says his early confidence in a vaccine began as optimism informed by previous Ebola-vaccine work, then strengthened after antibody survey results suggested only a small share of the population had been exposed. He says that evidence led him to reject infection-led herd immunity and favour suppressing the virus while backing several vaccine candidates. These are his retrospective account and interpretation of the evidence.
- Hancock says a vaccine by Christmas was set as a mission in January
- He reports that low antibody prevalence made widespread infection an unacceptable route in his view
- He says the strategy became suppression until vaccination could reduce risk
- The government backed a British programme while buying access to candidates developed elsewhere
- Hancock presents diversified purchasing as protection against candidate failure
“At first it was faith and it gradually became more and more real.”
“the policy became to suppress the virus until a vaccine makes us safe”
