Qatari study reveals effectiveness of vaccination, prior infection in preventing Covid-19

Doha: A study carried out by investigators and collaborators from Qatar's healthcare system and research institutes supports previous research showing that full vaccination and prior infection are both highly effective at preventing Covid-19 and rationalizes resumption of international travel in the era of Covid-19.

The research paper, published in the prestigious Journal of the American Medical Association, involved a team of researchers from the Ministry of Public Health, Hamad Medical Corporation, Weill Cornell Medicine-Qatar, and Qatar University. Dr Roberto Bertollini, Senior Advisor to the Minister of Public Health and Deputy National Lead for Health in All Policies, and lead study investigator, explained the study aims. "Using PCR test data for residents arriving on international flights to Doha's Hamad International Airport, we assessed whether full vaccination with either Pfizer-BioNTech or Moderna vaccines, and prior infections, prevented SARS-CoV-2 infection among incoming travelers."
