The same study found two doses of the Pfizer vaccine offered similar levels of protection against the virus as previously having the virus. There’s a lot of variation in our bodies’ responses to the jabs – and indeed to having Covid – so people are interested whether tests can tell us our level of immunity after having them. We don’t yet have widely available tests that can tell us specific things about our level of immunity. “T lymphocytes [or T cells] are essential for a normal, efficient immune response to a virus, and for making good ‘immune memory’,” explains Professor Charles Bangham. If you catch Covid-19 for a second time and your symptoms are mild – or you’re asymptomatic – it’s likely you’ve developed some level of immunity.
