The World Health Organization (WHO) cautioned on Saturday that there is no proof that individuals who test positive for coronavirus are vaccinated and ensured against reinfection.
The admonition recommends that the issuance of “insusceptible travel papers” may advance the proceeded with spread of the pandemic.
“There is at present no proof that individuals who have recuperated from #COVID19 and have antibodies are shielded from a subsequent contamination,” WHO said in an announcement.
“Starting at 24 April 2020, no investigation has assessed whether the nearness of antibodies to SARS-CoV-2 gives resistance to ensuing contamination by this infection in people.”
A few governments, needing a slow come back to work and the resumption of financial movement, have advanced the possibility of giving records bearing witness to the insusceptibility of individuals based on serological tests uncovering the nearness of antibodies in the blood.
In any case, the adequacy of a vaccination on account of antibodies has still not been set up and the accessible logical information don’t legitimize the giving of an “invulnerable visa” or a “testament of nonattendance of hazard”, cautions the WHO.
Now in the pandemic, there isn’t sufficient proof about the adequacy of counter acting agent interceded insusceptibility to ensure the precision of an “invulnerability identification” or “hazard free testament.”
“Individuals who accept that they are invulnerable to a second disease since they have gotten a positive test outcome may overlook general wellbeing counsel,” the WHO said.
“The utilization of such authentications may along these lines increment the dangers of proceeded with transmission.”
WHO likewise accepts that the serological tests at present utilized “need extra approval to decide their precision and unwavering quality”.
Specifically, the tests need to make it conceivable to recognize the resistant reaction to the novel coronavirus from the antibodies created during a disease by one more of the six known human coronaviruses, four of which are broad, causing gentle colds.
The other two are liable for MERS (Middle East Respiratory Syndrome) and SARS (Severe Acute Respiratory Syndrome).
“Individuals contaminated with either of these infections are fit for delivering antibodies which interface with antibodies created because of disease brought about by SARS-CoV-2”, said WHO, empasising the significance of having the option to recognize them.
