A study led by virologist Alex Sigal, at the African Health Research Institute in Durban, South Africa, found that serum – the antibody- containing portion of blood — from 12 people who received the Pfizer- BioNtech vaccine was 40 times less potent against Omicron, on average, compared to an earlier strain of SARS-CoV-2. That was similar to two other studies: one reported by Pfizer and BioNtech in an 8 December press release,and the other released on Twitter by virologist Sandra Ciesek at Goethe University in Frankfurt, Germany.
