Is it safe to combine Pfizer with AstraZeneca?
Those who have been vaccinated with a first dose of AstraZeneca can safely and effectively receive a second dose of Pfizer. This is the main conclusion reached by Combivacs, the clinical trial being carried out by the Carlos III Institute in Madrid on the combination of vaccines.
The preliminary conclusions of this work have been resounding: the administration of a booster dose of Pfizer is highly immunogenic, to the point that it causes an increase in antibodies of between 30 and 40 times between 7 and 14 days after inoculation. In addition, this effect translates into a protective response seven times more powerful than that caused by repeated vaccination with AstraZeneca.
How many cases of thrombosis by AstraZeneca has Spain reported?
The Ministry of Health made the decision at the beginning of April to vaccinate with AstraZeneca only those over 60 years of age due to the appearance of “very rare” thrombotic events, especially in younger people, following the example of other European countries such as France or Germany. .
In this sense, the Ministry has detailed that, in Spain, the number of cases of thrombosis with thrombocytopenia reported in the population aged 30 to 39 years is 14 cases per million; in that of 40 to 49, of a total of 12 cases per million. In addition, it has confirmed 4 deaths after being vaccinated with AstraZeneca, with an average age of 43 years and there is a fifth case under study. Thus, the decision of the Ministry of Health seeks to prevent one death for every million vaccinated” with the serum of the Anglo-Swedish company, reports Europa Press.
