On Friday, April 24th, The World Health Organization warned that people who have had Covid-19 and recovered are not necessarily immune to getting the virus again.

In a scientific briefing from the United Nations agency on Friday, it was said that there is no proof that having the virus one time leads to immunity. They cautioned against governments that are considering handing out “immunity passports” or “risk free certificates” as these are documents that would allow people who have recovered from COVID-19 to travel or go to work.

“At this point in the pandemic, there is not enough evidence about the effectiveness of antibody-mediated immunity to guarantee the accuracy of an ‘immunity passport’ or ‘risk-free certificate,’ ” WHO stated. “No study has evaluated whether the presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection by this virus in humans.”

As of now, the vaccine for COVID-19 is still being hunted for around the world. Regardless of whether someone has had the virus or not, they should still be cautious of catching it.
