A new study showed that over 90 percent of Britons produced antibodies to Coronavirus after receiving one dose of the AstraZeneca or Pfizer vaccine.
The study conducted by University College London was based on 8,517 people in England and Wales and it discovered that 96.42% of people who took either of the vaccines had produced antibodies 28 to 34 days after their first dose.
The researchers also found that the number rose to 99.08 per cent within seven to 14 days of the second jab.
Both vaccines were equally good at producing the antibodies required to fight off Covid-19, the researchers found. However, almost identical antibody positivity rates were observed among recipients of either vaccine after four weeks.
