Study finds antibodies against Sars-CoV-2 three-and-a-half times higher in people vaccinated again after 12 weeks rather than three
The UK’s decision to delay second doses of coronavirus vaccines has received fresh support from research on the over-80s which found that giving the Pfizer/BioNTech booster after 12 weeks rather than three produced a much stronger antibody response.
A study led by the University of Birmingham in collaboration with Public Health England found that antibodies against the virus were three-and-a-half times higher in those who had the second shot after 12 weeks compared with those who had it after a three-week interval.
