Minule som cital, ze pri Covide bude pravdepodobne dolezitejsia ochrana pomocou specifickych T-Buniek (protilatky produkuju B-Bunky), ktore sa vytvoria pri prvom strete s virusom a nasledne vydrzia roky. To by vraj mohlo aj indikovat, preco niektori ludia nemaju ziadne priznaky alebo iba minimalne. Pravdepodobne v minulosti prekonali nejake ine coronavirusove ochorenie (u nas aj pod nazvom nadcha), ktore je asi geneticky dost pribuzne na to aby uz existujuce T-Bunky vedeli zareagovat aj na Covid19.

Some early studies have suggested that coronavirus antibodies fade relatively quickly, but that doesn't mean immunity vanishes.

A new study found that all participants infected with COVID-19 — even those with asymptomatic or mild cases and patients who didn't have detectable antibodies — developed virus-specific T cells.

T cells identify and kill infected cells, and B cells create new antibodies. Those cells can attack the virus if it ever returns.

So the new finding is strong evidence that all patients likely develop long-term immunity.
