Pfizer, AstraZeneca vaccine antibody levels may decline in 2-3 months: Study
According to study published in The Lancet journal, total antibody levels start to wane six weeks after complete immunisation with Pfizer and AstraZeneca vaccines, and can reduce by more than 50 per cent over 10 weeks.
“The levels of antibody following both doses of either the AstraZeneca or Pfizer vaccine were initially very high, which is likely to be an important part of why they are so protective against severe COVID-19,” said Madhumita Shrotri from UCL Institute of Health Informatics.
“However, we found these levels dropped substantially over the course of two to three months,” Ms Shrotri said in a statement.
