HuffPost UK reader Sue asked: “Is there a test for the level of immunity after having the jab?”
There are a lot of things we know about Covid antibodies – but equally, many things we’re still in the dark about.
Antibodies are a type of blood protein produced when your body fights off a specific illness – so when you catch Covid-19, for instance, and your body manages to overcome it, you’ll produce antibodies that know how to fight the virus better next time so you hopefully don’t become as ill.
We know that in people who’ve been infected with the virus, antibodies last at least six months in their system. They might actually last longer, but because SARS-CoV-2 has only been knocking around for a relatively short amount of time, we can’t say for sure that people have protection longer than that.
