A population-based seroepidemiological study done in Spain indicates the prevalence of antibodies against COVID-19 in the general population is very low and not sufficient to provide herd immunity, according to a study published in Lancet.

Key Findings of the study:

• Study involved more than 61,000 people from across the country and is suggested to be the largest European study to check the seroprevalence of SARS-CoV-2 antibodies so far.

• All the individuals were tested twice - once with a point of care rapid test and again with a lab-based immunoassay test - for the presence of IgG antibodies in their blood.

• The seroprevalence was found to be in the range of 3.7 to 6.2 per cent depending on if we look for specificity (positive result in both tests) or sensitivity (positive result in one of the tests).

• Antibody levels were low in people above the age of 85 and children below the age of 10. The latter was suggested to be due to less ACE-2 receptors in the nasal mucosa.

• Healthcare professionals had a higher seroprevalence but that is suggested to be due to their higher exposure to the virus.

How much one can rely on Lancet, its credibility already sold to pharma industry.

UK population has already shown antibodies in the range of 16 percent.
