A newly pre-published paper giving an analysis of data from 500,000 Israeli people following vaccination with the Pfizer vaccine shows two interesting features 1) Effectiveness after the first dose the was zero at day 14 then increased gradually, reaching about 90% on day 21. There is no data beyond 21 days as that is when the 2nd dose is given. However, following on from the data in the Oxford vaccine paper mentioned in my previous post, the immunology suggests there will be no significant decline in this response out to the 12 week point where the UK will give the second dose. 2) After the first few days there was a big increase in incidence of Covid in the week after the first injection. They surmise that this is because people had stopped taking protective measures. If that is the case then it will be interesting to see if we get the same thing showing up here. However, there was no zero point testing of people so I would say that they can't rule out people getting actually getting infected at the vaccination centres. At least we now have some data that support delaying the Pfizer vaccine's second dose - although the projection of protection out to 12 weeks is only theoretical and we could still do with a study with hard data for this period. see report at https://www.medrxiv.org/content/10.1101/2021.02.01.21250957v1
