As we know, Australian researchers have found that body's immune response to COVID-19 is similar to influenza. Now my question is: "Does getting influenza give some immunity against COVID-19?"
No, different virus altogether. Chances of cross immunity would be exceedingly small as the protein structures the immune system would have stored to react to would not match the coronavirus
even so ,SARS CoV 2 ability to highly proliferation it inhibit lymphocytes production that lead to reducing antibodies responses aand this clarify why relapse occurred with COVID 19
No
During flu season, much of the population is already immune. Immune system might recognise the viral enemy from a previous infection and pump out antibodies to clear the contagion. Or you might have received a flu shot, a dose of dead influenza viruses that trains your body to fend off a live attack.
People with immunity, whether by infection or injection, help keep the greater public relatively safe from the flu, When the virus infects them, it reaches a dead end. They don't get sick, they don't pass it on. And they stop the virus in its tracks.
That's not the case for the new coronavirus.Beyond a lack of immunity, testing mishaps and unproven treatments make the novel coronavirus pandemic a new and distinct challenge from influenza outbreaks, which researchers have been working to control for decades.
