In the global effort to overcome COVID-19, much scientific and medical attention has focused on the ability of our immune system to generate antibodies. Antibodies are one of our body’s main weapons against viruses, created to recognize specific proteins on a virus’s surface and initiate processes that ultimately neutralize and remove the virus.

We know that for other human coronaviruses, when the body creates antibodies against them, these then go on to provide immunity. Teams developing vaccines against SARS-CoV-2 are confident, therefore, that their vaccines can produce similarly effective responses against COVID-19. But there is still much to understand – not least how long these vaccines will protect us for. Luckily, science is gradually catching up with the virus, and we are starting to understand more about antibody responses to it.
