A “remarkable” study suggests coronavirus antibodies do help to ward off a second infection.

Antibodies are immune-fighting proteins that circulate in the bloodstream after an individual has overcome a pathogen (a bacterium, virus or other microorganism that can cause disease).

Although these help to prevent an infection taking hold for a second time, concerns have been raised about how effective or long lasting they are when it comes to the coronavirus outbreak.

With vaccines only beneficial if they trigger an immune response, many worry fleeting immunity may hinder a much-wanted immunisation programme.

Well yes. Antibodies are one part of the immune system. The question is, has the system learned to produce them on demand after an infection or no. 

 

Centivax has also made good progress on their antibody therapy: https://www.biospace.com/article/releases/centivax-antibody-effective-in-reducing-covid-19-lung-damage-virus-levels-and-symptoms-as-both-therapeutic-and-preventative-in-healthy-and-immunocompromised-hamsters-confirmed-by-multiple-national-laboratories/
