Španjolsko istraživanje o kombiniranju cjepiva protiv covida-19 utvrdilo je da je cijepljenje Pfizerovim cjepivom ljudi koji su dobili prvu dozu AstraZenecina cjepiva jako sigurno i učinkovito, pokazali su preliminarni rezultati objavljeni u utorak.

Istraživanje Combivacs, koje je proveo španjolski Institut za zdravlje Carlos III., utvrdilo je da je količina IgG antitijela u krvotoku od 30 do 40 puta veća kod ljudi koji su kao drugu dozu dobili Pfizerovo cjepivo nego u kontrolnoj skupini u kojoj su bili ljudi koji su dobili samo prvu dozu AstraZenece.

Istodobno, količina neutralizirajućih antitijela porasla je sedam puta nakon doze Pfizerova cjepiva, značajno više nego nakon druge doze AstraZenecina cjepiva kada su se ona udvostručila.
