PARIS - Covid-19 patients may experience more severe symptoms the second time they are infected, according to research released on Tuesday confirming it is possible to catch the potentially deadly disease more than once.
The second infection was more severe than the first, resulting in the patient being hospitalised with oxygen support. In particular, it could influence the hunt for a vaccine - the currently Holy Grail of pharmaceutical research. WANING IMMUNITY? Vaccines work by triggering the body's natural immune response to a certain pathogen, arming it with antibodies it to fight off future waves of infection. But it is not at all clear how long Covid-19 antibodies last.
The researchers pointed out that reinfection of any kind remains rare, with only a handful of confirmed cases out of tens of millions of Covid-19 infections globally.
