The under 60 years vaccinated AstraZeneca will receive the second dose from Pfizer. This was decided on Tuesday by the Public Health Commission, which ended up supporting the initial proposal of the Ministry of Health, although it will continue to debate whether they are offered the possibility of choosing between one or the other “given the exceptional circumstances”, as requested by some communities.
The decision was made after knowing the preliminary results of CombiVacs, the trial promoted by the Carlos III Health Institute that confirms that the mixture of both vaccines enhances the immune response and does not generate more side effects than those already known, mostly mild and moderate.
In addition to this study, the general directors of the Ministry and the communities have taken into account the observational studies of other countries and the Oxford clinical trials, in which case it pointed out that alternating doses of different vaccines against covid causes mild and moderate reactions more frequent than with two injections of the same preparation.
Spain is not the only country that has opted for this option, in which AstraZeneca and Pfizer are combined for those under 60 years of age. Germany, France, Portugal, Sweden and Finland have also opted for this mixed pattern.
Option with AstraZeneca
However, the meeting between Health and the communities raised the possibility that those who do not wish to use a second dose Pfizer may choose AstraZeneca “given the extraordinary circumstances”, although this issue will continue to be debated in the Health Commission Public
Health has thus made its proposal prosper, which was to combine both vaccines, although it has done so with the reluctance of a vast majority of the scientific and medical community, which has asked from the beginning that these people finish their immunization with the Anglo-Swedish serum, as recommended by its technical data sheet and the European Medicines Agency (EMA).
Several communities do not share the criteria either. This is the case of Madrid. “We continue with our idea of continuing to administer the second dose of AstraZeneca due to the technical support that this decision has,” the Health Minister explained last night, in statements to the Ser string.
Almost two million people
As of now, nearly two million citizens, mostly essential workers under the age of 55 for whom the interval between doses has been extended from 12 to 16 weeks, now hope to complete their vaccination. In the end, with the Pfizer serum.
The department headed by Carolina Darias believes that the guideline can be completed in the next few days. “The vaccination rate it will continue to be very agile given the large number of vaccines that are arriving in our country these weeks “, explains Health, in statements collected by Efe.
