England Vaccine TL;DR
            Updated daily using official NHS data.

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 all adults by the 31st of July
                (source). This makes up 78.2% 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 age breakdowns 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). 2nd doses are prioritised above
            1st doses.
        
        
            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.
