Scientists from the University of Oxford warned about the possibility of a larger number of side effects after mixing vaccines from COVID-19 Astrazeneca and Pfizer. The results of the study publishes the Edition Insider.
Tests were carried out on participants over 50 years, vaccines were introduced at intervals at four weeks. It was found that light and moderate reactions to the vaccine, such as fatigue and headache, were observed much more often when two different vaccines were introduced, rather than when a person was given twice alone.
Describing the results, the author of the study and Professor Oxford Matthew Snape (Matthew Snape) told reporters that the side effects “are more or less similar to the same reactions that we observe with standard situations, they simply arise more often.” According to Snape, symptoms, although unpleasant, but do not represent dangers.
From important consequences allocated the increased probability of severe fatigue – quite serious to seek help from a specialist. It was found at about ten percent of the participants when mixing the doses of the vaccine compared to about three percent from another subject group.
As stated in the study, all the symptoms have disappeared within 48 hours. Scientists stated that none of the participants in the study was hospitalized. However, Snape recalled that a more fundamental question about mixing vaccines – whether it gives better protection from COVID-19 – still remains unanswered.
