The United Kingdom today advised against the use of the AstraZeneca / Oxford vaccine in people under 30 years of age, as a precautionary measure after reporting some cases of thrombosis in people who received the preparation.
Adults between 18 and 29 years of age who do not have any disease should be offered a different vaccine than AstraZeneca whenever possible, recommended this Wednesday the chairman of the Joint Committee on Vaccination and Immunization (JCVI) of the United Kingdom. , Wei Shen Lim.
As Lim explained in a televised press conference, it is still unknown whether the thrombi are related to the preparation developed by the Anglo-Swedish pharmaceutical company and the University of Oxford, or to any other, but that it is a precautionary measure.
The expert also pointed out that people who have already received the first dose of the vaccine must receive the second to complete the treatment.
In this regard, the director of the UK Medicines Regulatory Agency, June Raine, stated that the benefits of the AstraZeneca / Oxford product far outweigh the risks for the majority of the population.
According to the official, until March 31, more than 20 million doses were applied and only 79 cases of thrombosis were reported among people between 18 and 79 years of age who received the injection, for an average of four per million.
He added that of the total of adverse reactions, 19 led to the death of the patient, while in terms of gender, 51 cases occurred in women and 28 in men.
While admitting that there is a high probability that blood clots are related to the vaccine, Raine stressed that more research is still needed to determine, beyond a reasonable doubt, that the injection is the cause of this side effect.
Like her colleague from the JCVI, the director of the British regulatory agency said the benefits outweigh the risks.
More than 31,7 million people have so far received at least one dose of the AstraZeneca / Oxford or Pfizer / BioNTech vaccines in the United Kingdom, where this Wednesday the preparation developed by the American laboratory Moderna was also applied.
The government's plan is that by the end of July the entire adult population of the country - estimated at about 53 million - will have had the opportunity to be immunized against Covid-19.
In the last hours there were also 763 new positive cases of the disease and another 45 deaths, for a total of 367 infected and 126 deaths since the start of the pandemic.
