Portugal to continue with AstraZeneca vaccine

National authorities see no cause for concern

AstraZeneca vaccine

Publico reports that shipments of the AstraZeneca vaccine associated with cases of clot formation that are suspected to be linked to the vaccine in other countries have not been distributed in Portugal. A pharmacovigilance system received notification of two cases but these did “not have the same clinical pattern as those being evaluated” in other countries.

The Directorate-General for Health (DGS) and medical authority Infarmed clarified, in a joint statement, that the vaccine of the company AstraZeneca against COVID-19 will continue to be administered in Portugal because “there is no evidence” of it being linked to a greater risk of the formation of blood clots.

This Sunday, Ireland joined a group of European countries that, as a precautionary measure, suspended the administration of the vaccine from AstraZeneca.

So far, inform the entities in a statement, “the Pharmacovigilance System has received notification of two cases, and they do not have the same clinical pattern as those under evaluation.” “Based on currently available data and while the investigation is ongoing ”, The vaccine will continue to be administered in Portugal.

DGS and Infarmed report, however, that “the number of thromboembolic events reported in the vaccinated population in the European Union (around five million doses) and in the United Kingdom (around 11 million doses) continues to be no higher than that observed in the general population”, and “so far there is no evidence that vaccination may be at the origin of these events”.

The issue “continues to be followed up by the national health authorities”, concludes the communiqué, mentioning the participation of the Portuguese authorities “in the evaluation that is taking place at European level together with the European counterparts, namely in meetings taking place next week”.

AstraZeneca does not identify increased risk of clots associated with the vaccine

The same newspaper reports that the pharmaceutical company AstraZeneca reported on Sunday that it carried out an assessment of people vaccinated with their covid-19 vaccine and that the investigation found no evidence of an increased risk of blood clots. This verification process involved more than 17 million people vaccinated in the European Union and the United Kingdom. 

“A careful assessment of all available safety data, for more than 17 million people vaccinated in the European Union and the United Kingdom with the AstraZeneca covid-19 vaccine, has shown that there is no evidence of an increased risk of pulmonary embolism , deep vein thrombosis or thrombocytopenia [or thrombocytopenia], in any group defined by age or gender, lot or country ”, reads the company statement.

The authorities in Denmark, Norway and Iceland have  suspended the administration of the AstraZeneca vaccine  after cases of blood clots have appeared in vaccinated people. Last week, Austria suspended the batch of vaccines associated with the identified cases, while investigating a death caused by the formation of clots. Ireland, meanwhile, temporarily suspended the administration of the AstraZeneca vaccine on Sunday, “as an added precaution”.

The pharmaceutical company said that additional tests are being conducted by both AstraZeneca and European health authorities. The company adds that none of the tests have so far shown reason for concern.

AstraZeneca added that there were no confirmed problems related to the quality of any of the batches of its covid-19 vaccine used in Europe or the rest of the world. 

Under analysis are lots ABV5300 (suspended by the authorities of Austria, Estonia, Latvia, Lithuania and Luxembourg) and ABV2856 (suspended in Italy and Romania) of the AstraZeneca vaccine, which “ were not distributed to Portugal ”, according to a joint clarification. released on Friday by DGS and Infarmed.

  1. People get blood clots. People are living more sedentary lives due to lockdown which will contribute to the likelihood of clots or DVT.

    It is another knee-jerk reaction when countries stop using the AZ vaccine.

    Remember, if anyone asks “what is the best vaccine?” The correct answer is — “the one in your arm!”

  2. Sorry,

    I Would Rather Be Warned 20 Times Of A New Article Than Have No Warning, At All.

    But, Your Email Warnings Are Experiencing Some Kind Of Loop – Please, Check It Out ( Check Your Output Emails To My Address, For Example ).


  3. I have absolutely no idea how safe Astra is compared to other vaccines.
    But if I would have a choice (unfortunately, I do not have a choice) I would never accept a product from that company – because of their lying and cheating arrogant management.
    They are great contributors to the idiotic ideas of idiotic anti vaxxers!
    They even managed to do what Farage and Paisley jr could only dream of: create a breach of trust between UK and EU citizens.
