Research: it’s safe to have two doses of different vaccines


While the number of doses applied within the scope of combating corona virus exceeded 1.5 billion, a study was carried out on the application of two doses from different vaccines in Spain.

In the study of applying two doses from different vaccines for the first time, it was revealed that giving the second dose of BioNTech / Pfizer vaccine to people with the first dose of AstraZeneca vaccine was quite safe and effective.

In the study called Combivacs, conducted by the Spanish state-sponsored Carlos III Health Institute, it was found that the presence of IgG antibodies in the bloodstream was 30 to 40 times higher when people with the first dose of AstraZeneca vaccine were given the second dose of BioNTech / Pfizer vaccine.

‘BECOMING THE SECOND DOSE BÄ°ONTECH INCREASED SEVEN TIMES’

It was reported that the presence of virus-neutralizing antibodies in their blood doubled when people who received the first dose of AstraZeneca vaccine received the second dose of AstraZeneca, while the antibody levels of those with the second dose of BioNTech / Pfizer vaccine were reported to increase seven times.

The study was conducted on 670 volunteers between the ages of 18-59, whose first dose was AstraZeneca, and 450 of them were given the second dose of BioNTech / Pfizer vaccine.

No SERIOUS SIDE EFFECTS OCCURRED

Dr Magdalena Campins, one of the study leaders, said that only 1.7 percent of the participants reported side effects such as headaches, muscle pain and general weakness, saying “These are not symptoms that can be considered serious.”

“The results announced today indicate that patients who received the first dose from AstraZeneca are likely to receive another vaccine,” said Jesus Antonio Frias, clinical director of the Carlos III Health Institute.
