England Vaccine TL;DR

Updated daily using official NHS data.

Percent of England vaccinated

Percent of >80s⁴ vaccinated

England vaccinated over time

¹ The Pfizer vaccine is 95% effective 7 days after the 2nd dose (source).
² The government has committed to offering the 1st dose of the vaccine to everyone in the top four priority groups by the middle of February (source). This makes up 20.5% of the population.
³ WHO estimates we will reach herd immunity once 60-70% of the population has been vaccinated (source). In this scenario, this means both Pfizer doses have been administered and 7 days has passed. This does not take into account new strains or different types of vaccines.
⁴ NHS doesn't provide daily data broken down by age group. This means we guess the daily >80s vaccinations using a combination of the daily and weekly data.

Predicting vaccinations

We make some simple guesses about the future of England's vaccinations, using (1) how many vaccines were given in the last week, and (2) the 12 week gap between 1st & 2nd doses (as stated by the UK government).
Disclaimer: While these graphs are based on official NHS data, we make some inferences from the data. We have aimed to document all inferences here. These inferences aim to be as simple and interpretable as possible, so that visitors can build an intuition about the state of the vaccine rollout, but it should not be assumed that these inferences are accurate. This was made by someone with no medical or epidemiological experience.
