‘The Lancet’ assures that the scheme is more successful than the application of the two doses of the same company

A study by the British University of Oxford and published by the journal “The Lancet”, pointed out that it is safe and effective to combine the AstraZeneca and Pfizer vaccines against COVID-19 , despite the fact that their development is different.

The publication, revealed by “The Lancet”, ensures that the scheme is more successful than the application of the two doses of the same company.

Hundreds of UK volunteers, over 50 years of age and without comorbidities, developed a heightened immune response after first receiving Pfizer and 28 days later AstraZeneca .

Its effectiveness was 100 percent against severe COVID-19 and 76 percent against mild symptoms.
