Bamlanivimab monoclonal antibodies interacting with COVID vaccines
Post-COVID Recovery & COVID-19 | Last Active: May 9, 2021 | Replies (12)Comment receiving replies
This past February, my wife and I tested pos for the virus and received the Bamlanivimab transfusion from Eli Lilly. I am trying to find out why we would need to be vaccinated, as recovery from the virus should have produced antibodies and provided immunization as well as having the antibodies from the transfusion. Appreciate any info and/or references!

@mlmc21 Thank you for telling us about your experience.
@mal I have looked all over the Lilly and CDC sites, and didn't find a definitive answer for you. So, I went to my secondary source. My daughter is a telemed nurse, and has been dealing with all things Covid since last March. I asked her about what they tell patients about vaccine after infusion and why. Her large urban hospital/clinic group updates their Covid guidance at least daily.
Their advice, from the Infectious Disease and Epidemiology docs is to wait 90 days after test-confirmed infection or antibody infusion and get the vaccine.
The reason - the monoclonal antibodies are intended to provide a temporary boost to the immune system, and they don't know how long the antibodies will last. Typical after-virus antibodies range from undetectable to lasting about 4-5 months for most people.
With the vaccine there is good evidence that immunity lasts at least 7 months, based on regular testing of the early recipients in the clinical trials.
Also, her plea to you: "Please get vaccinated - we see people every day who have Covid for the second time. Even though this can and does happen after full vaccination symptoms are more mild."
