Overview: The National ENE-COVID Seroprevalence Study concludes that 5% of the Spanish population have antibodies against SARS-CoV-2. This percentage has hardly changed during the three waves of the study: 5% during the first, and 5.2% during the second and third. The results confirm that, despite the significant impact of the pandemic in Spain, these figures are not high and reject any possible short-term herd immunity. The release of these final results coincides with the publication of a scientific article in The Lancet. The three rounds of this study, which was promoted by the Ministry of Health and the Carlos III Health Institute (the latter managed under the Ministry of Science and Innovation) and in which the healthcare systems of all the autonomous regions and the autonomous cities of Ceuta and Melilla took part, were conducted from 27 April to 11 May; from 18 May to 1 June; and from 8 June to 22 June.
It included a total of 68,296 participants, of which 54,858 took part in all three rounds, representing an almost 90% level of adherence. Furthermore, 91% of participants provided at least one blood sample for analysis.
In total, 186,908 rapid tests were performed (plus 9,755 in the island-specific study) and 165,176 blood samples were collected (plus an extra 9,130 in the island-specific study). These results emphasise the need for maintaining public health measures to avoid a new epidemic wave.
