Sonia Acevedo, 41, suffered a ‘sudden death’ at home on New Year’s Day 48 hours after receiving the jab. An autopsy is expected to take place later today or tomorrow.
The mother-of-two, who worked in paediatrics at the Portuguese Institute of Oncology in Porto, is not said to have suffered any adverse side-effects after being vaccinated.
Ms Acevedo’s father Abilio Acevedo told Portuguese daily Correio da Manha: ‘She was okay. She hadn’t had any health problems.
‘She had the Covid-19 vaccine but she didn’t have any symptoms. I don’t know what happened. I just want answers.
‘I want to know what led to my daughter’s death.’
Ms Acevedo’s employers confirmed the dead woman had been vaccinated against coronavirus on December 30 and said they had not been notified of any ‘undesirable effect’ when she was jabbed or in the hours afterwards.
The Portuguese Institute of Oncology said in a statement: ‘With regards to the sudden death of an operational assistant from the Porto IPO on January 1, 2021, the Board of Directors confirms the event and expresses sincere regret to family and friends in the certainty that this loss is also felt here.’
It added: ‘The explanation of the cause of death will follow the usual procedures in these circumstances.’
Ms Acevedo had worked at IPO Porto, a national and international reference health institution in cancer treatment, research and education, for more than 10 years.
She lived with her family in Maia near Porto but died at her partner’s home in Trofa half an hour’s drive north of the northern Portuguese city.
She changed her profile pic on Facebook shortly after her jab to post a selfie with a face mask on and the message: ‘Covid-19 vaccinated.
Her father told Portuguese press he got the call to say she had been found dead around 11am last Friday morning hours after they ate together on New Years Eve, adding: ‘My daughter left home and I never saw her alive again.’
Ms Acevedo’s daughter Vania Figueredo said her mum had only complained about the ‘normal’ discomfort in the area where she was jabbed but was otherwise fine.
The health worker was one of 538 Porto IPO workers who received the Pfizer-BioNTech vaccine.
Portugal’s Ministry of Health has been informed.
Portugal, with a population of just over 10 million, has reported 7,118 deaths and more than 427,000 cases.
After a relatively mild first wave, cases rose sharply in the second and have spiked again since Christmas.
This is the second time within a few days with reports of such frightening stories about the Pfizer Coronavirus vaccine.
In California in the United States, a story emerged few hours to Christmas, when a 45-year-old nurse in California tested positive for Covid-19 more than a week after receiving Pfizer’s coronavirus vaccine.
According to an ABC News affiliate which reported on Tuesday Dec 29, Mr Matthew W., a nurse at two different local hospitals, said in a Facebook post on Dec 18 that he had received the Pfizer vaccine, telling the ABC News affiliate that his arm was sore for a day but that he had suffered no other side effects.
Six days later, on Christmas Eve, he became sick after working a shift in the Covid-19 unit, the report added. He got the chills and later came down with muscle aches and fatigue.
He went to a drive-up hospital testing site and tested positive for Covid-19 the day after Christmas, the report said.
Dr Christian Ramers, an infectious disease specialist with Family Health Centres of San Diego, told the ABC News affiliate that this scenario was not unexpected.
“We know from the vaccine clinical trials that it’s going to take about 10 to 14 days for you to start to develop protection from the vaccine,” Dr Ramers said.
“That first dose we think gives you somewhere around 50 per cent, and you need that second dose to get up to 95 per cent,” Dr Ramers added.
