Study confirms protection provided by Pfizer/BioNTech vaccine after the first dose

Yesterday Public Health England published a landmark UK study showing the Pfizer/BioNTech vaccine provides effective protection against Covid-19 from the first dose, proving that the vaccine protects people and their loved ones around them.

  • As we continue to rollout lifesaving vaccines, it is important that we see as much evidence as possible on the impact they are having on protection and on transmission, and we will continue to publish evidence as we gather it.
  • This crucial report shows the vaccines are working and that the Pfizer-BioNTech vaccine offers both a high degree of protection to those that take it, reducing hospitalisation and death by 75 per cent after the first dose, and reduces transmission, helping to protect others too.
  • That isn't the only recent encouraging data. Apart from the continuing stats from Israel suggesting that the vaccination programme is helping, Public Health Scotland (PHS) has been working with Scientists from the Universities of Edinburgh, Strathclyde, Aberdeen, Glasgow and St Andrews who looked at data on people who had received either the Pfizer/BioNTech jab or the one developed by scientists at the University of Oxford with AstraZeneca.
  • They found that four weeks after receiving the initial dose, the Oxford jab appeared to reduce a person's risk of hospital admission by 94%.
  • Those who received the Pfizer jab had a reduction in risk of 85% between 28 and 34 days after the first dose.
  • Data for the two jabs combined showed that among people over the age of 80 - who are at high risk of severe disease - the reduction in risk of hospital admission was 81% four weeks after the first dose.
  • While this is fantastic news we are not out of the woods yet, and as we roll out the jab, it is vital people continue to play their role in protecting the NHS by sticking with the rules.
        All these studies were showing that the first jab provides protection four weeks after it had been taken. Studies from Israel suggested that there was an effect from two weeks after the jab. We should assume that it takes between two and four weeks for the protective effect to kick in:
