Why some people don’t get infected with the coronavirus
The first theory says that certain people are able to eliminate the new coronavirus. That’s thanks to the neutralizing antibodies and memory T cells they have in their body, the product of having suffered from old colds.
There are four types of coronaviruses that cause 30% of colds in humans.
The second theory says that certain human beings are capable of producing substances within their cells. These are substances that not only destroy the invading virus, but also destroy the infected cell.
Three studies support the first theory, which says that having suffered multiple colds in a lifetime, neutralizing antibodies and memory cells directed against these viruses may cross-protect against the new coronavirus.
