We extract the primary data from Israel to,

estimate the incidence per day for each day after the first injection

N = 500,000

Retrospective cohort study

Infections over first 24 days = 3,077

Days 0 to 8

Case numbers increased (x 2)

Day 0 to day 14

Estimated vaccine effectiveness was pretty much zero

Day 8 to day 21

New cases declined
At day 21

Vaccine effectiveness, 91%

After day 21

Remained at 90%

Expected to last form 9 weeks to 6 months

Conclusion

A single dose of vaccine is highly protective

The early results coming from Israel support the UK policy of extending the gap between doses

Also

Vaccine effectiveness seems to be better at reducing severe disease that at reducing mild disease

Therefore, more than 90% protection against severe disease, hospitalisation and deaths

It may be more contagious than conventional strains,

and if it continues to spread domestically,

it could lead to a rapid rise in cases
