Spanish health authorities have approved cross-vaccination of AstraZeneca and Pfizer’s novel coronavirus infection (Corona 19) vaccine under the age of 60, Reuters reported on the 18th (local time), citing Spanish local media El Pais.

Elpais cited an anonymous source, saying that the Spanish Public Health Commission has approved a cross-vaccinating proposal proposed by the Spanish Ministry of Health. The plan is to allow nationals under the age of 60 who received the first dose of the AstraZeneca vaccine to receive the Pfizer vaccine during the second dose.

Spanish health authorities have changed the guidelines to ban the vaccine from being administered under the age of 60 and to be administered only to those aged 60 to 69 years of age, concerned about the side effects of blood clots from AstraZeneca vaccine. About 1.5 million people under the age of 60 who completed the first dose of the AstraZeneca vaccine before the change in the guidelines were changed.

Earlier on that day, the Spanish state-run Carlos III Health Research Institute revealed that it was “very safe and effective” as a result of cross-vaccinating 670 people aged 18 to 59 who were first vaccinated with the AstraZeneca vaccine. In particular, it was found that the immune effect was 30-40 times higher when the AstraZeneca vaccine was given and the Pfizer vaccine was used as the second vaccination compared to the first and second vaccinations with the single AstraZeneca vaccine.

The experiment was conducted in the form of comparing the two groups after 8 to 12 weeks of AstraZeneca vaccination had elapsed and Pfizer vaccine was administered to about 450 people, and no vaccine was given to the rest.
