More than 90% of people in the UK who have been vaccinated with a single dose of Pfizer or AstraZeneca vaccine have developed coronavirus antibodies, a rate that rises to almost 100% after the second dose.
New research from the University of London UCL based on 8.157 vaccinated citizens in England and Wales shows that 28 to 34 days after the first dose 96,42% had antibodies.
This percentage increased to 99,08% from seven to 14 days after the second dose.
