1/ Comparison of immune responses to Pfizer, Moderna, & J&J vaccines over 8 months post-vaxx.
Neutralizing antibodies:
- Pfizer: peaked high, then ⬇️ over time
- Moderna: peaked highest, then ⬇️ over time
- J&J: lower peak, but stable (?⬆️)over time
2/ Another look at neutralizing antibody responses for Pfizer, Moderna, and J&J vaccines over time:
3/ With all three vaccines, functional antibody responses (antibody-dependent cellular phagocytosis & antibody-dependent complement deposition) were stable over time:
- To become more transmissible (e.g. the Alpha & Delta variants)
- To evade immune responses (e.g. the Beta & Gamma variants)
- To become more virulent
