Health & Fitness Hospital accidentally gives woman wrong second Covid vaccine
Quick guide: COVID-19 vaccines in use and how they work
Here's a guide to the vaccines being used in different countries.Dozens of coronavirus vaccines entered clinical trials during 2020, and now, a handful have been authorized for emergency use in various countries — meaning the shots can be administered to the public while their developers continue to collect data on their safety and efficacy. Should they meet all the necessary criteria, these vaccines could be fully approved in the future, and in some places, they already have been.
A hospital has accidentally dished out the wrong second Covid vaccine dose to a woman, in what is believed to be the first error of its kind in Britain.
The patient — who wasn't identified — turned up at the Great Western Hospital in Swindon expecting to receive another shot of thejab.
But a mix-up meant she got thevaccine instead, her husband told the .
The woman said she felt okay afterwards but was left furious over the error.
The hospital has launched an internal review into how the mistake happened.
Britain's medical regulator says Covid vaccines should not be mixed, and everyone should receive the same second dose as they did for their first jab.
Covid vaccine: Can you still transmit Covid after full vaccination?
COVID vaccination programmes have provided 10 million Brits with their first dose, with more 20 percent of the country soon to adopt some form of immunity against coronavirus. Can you still transmit Covid after full vaccination? Full vaccination with one of the available candidates should afford people protection from 90 percent or more Covid cases.Ultimately, this will prevent people from catching severe cases of the virus, bringing the death rate down.But scientists still want to know whether inoculated people can spread the disease to others.
Scientists don't believe it is unsafe to alternate doses but say further data is needed to confirm this before the move is given the go-ahead. Oxford scientists are currently trialling whether the doses can be alternated, in the hope of making them more potent.
'MIXING AND MATCHING' COVID JABS TO BE TRIALLED
Coronavirus vaccines made by Moderna and Novavax will be added to a 'mix and match' trial, scientists say.
Britain's medical regulator currently requires everyone to have two doses of the same jab — either AstraZeneca, Pfizer or Moderna.
But Oxford University experts are testing whether alternating second doses could provoke a stronger immune response.
Their trial — which could revolutionise Britain's roll-out — was already assessing the effects of combining doses of AstraZeneca and Pfizer.
Covid vaccine alcohol: Can I drink a glass of wine after the Covid vaccine?
COVID vaccine programmes have successfully started whittling down global case rates, with profound effects noted in the US and Israel. Can you drink a glass of wine after the Covid vaccine? The Covid vaccine is a lifesaving scientific development which has significantly cut severe cases of the disease.The UK's programme has now covered nearly every vulnerable adult and will soon move on to people below 50.The vaccine is not instantly effective, however, and require a window to reach their full potential.
Another 1,000 volunteers were recruited to the study to test combinations including vaccines made by Moderna and Novavax.
Experts say mixing jabs is unlikely to pose any safety concerns and predict it could lead to shots being even more effective at preventing an infection with the virus.
In the wake of AstraZeneca's blood clot fears, France approved giving recipients an alternative second dose. Germany made the same move for under-60s.
But until evidence is gathered they can't say for certain whether it works or whether it is safe.
Britain has only recommended under-30s are offered an alternative and that anyone who has already had their first dose should come forward for their second, unless they suffered the extremely rare complication.
Oxford's mix-and-match trial was first launched in February, to investigate whether alternating doses of the Pfizer and AstraZeneca vaccines boosted efficacy.
Covid vaccine and breastfeeding: Can you breastfeed after having the Covid vaccine?
COVID vaccines in the UK have been being administered for months now as nearly half the adult population has received at least a first dose. But can you breastfeed after having the Covid vaccine? © Getty Covid vaccine and breastfeeding: vaccine "Evidence on COVID-19 vaccines has also been reviewed by the World Health Organisation (WHO) and the regulatory bodies in the US, Canada and Europe and has raised no concerns about safety in pregnancy."The Joint Committee on Vaccination and Immunisation (JCVI) has recognised that the potential benefits of vaccination are particularly important for some pregnant women.
The woman's husband, who was also not named, blasted the hospital and said they had made it clear his wife needed the AstraZeneca jab.
'I couldn't believe it, it's a huge error and very concerning,' he told the newspaper.
'They told us this is the first time it's happened — not just in Swindon but in the UK.'
Explaining how the error happened, he said: 'The call handler asked her (my wife) which vaccine she had last time so we assumed that would be written down and passed on to the medics.
'We split up into different rooms and when we came out, she told me what happened.'
He added: 'Afterwards a doctor came out and said sorry, but said we think you will be ok.
'It does not make sense, there would be a number of fail safes in place to ensure this does not happen. We couldn't understand how or why this had occurred.'
The woman said that at no point during the appointment did the healthcare staff ask to see the card she got after her first dose, although it was face up on the table in clear view.
Great Western Hospitals said despite the mix-up, the woman will not now need a third dose because the second should work to boost immunity from the first.
People waiting for first jab are NOT put off by blood clot fears
Concerns about highly-rare clots have done nothing to deter those waiting for their first dose of the vaccine. Here, Britons tell how they would 'snap someone's hand off' for the jab.A review by the drugs watchdog the MHRA found that by the end of March, 79 out of 20million Britons vaccinated with the AstraZeneca vaccine had suffered blood clots in the brain or arteries, a rate of about one in 250,000.
A spokesman for the Great Western Hospital said: 'We have offered our sincere apologies for giving her a different Covid vaccine as her second dose.
'We have taken advice from the South West Clinical Advice and Response Service, an external service that provides vaccination centres with expert advice and guidance.
'It advised that both of the currently authorised vaccines in this situation are based on the spike protein and so the second dose will work as it should to boost the response to the first dose.
'For this reason, no further doses are required, and we do not anticipate any ill effects arising from this.'
They added: 'We are reviewing the current pathways within our vaccination hub to learn from this incident and make sure similar incidents are avoided in the future.'
The Medicines and Healthcare products Regulatory Agency (MHRA) has ruled that Britons should not receive a different second dose to their first.
They say this is because there is a lack of data on whether alternating vaccines will make them less effective at blocking infections with the virus, and stopping Covid hospitalisations and deaths.
Oxford University scientists are investigating whether doses of the AstraZeneca and Pfizer vaccines can be alternated, however, with results expected later this year.
Pfizer vaccine efficacy: What protection does Pfizer vaccine give after second dose?
THE PFIZER Covid vaccine has been given to millions of people around the world, so what protection does the Pfizer vaccine give after a second dose has been administered?For the vaccine to be most effective, the Pfizer vaccine is given in two doses.
Experts say mixing the jabs is unlikely to pose any safety concerns, and predict it could lead to shots being even more effective at preventing an infection.
Professor Matthew Snape, who is leading the trial, previously said he would be 'surprised' if they found the alternated jabs triggered a less potent immune response.
The trials have recently been expanded to include the Moderna jab - also being dished out in the UK - and the Johnson and Johnson and Novavax vaccines - which are yet to get the green light from regulators.
Some countries have already started alternating vaccines despite the lack of data, after regulators linked vanishingly rare blood clots to the AstraZeneca vaccine.
In France, everybody under-55 has been told they should have an alternative to the AstraZeneca jab, even if they have already received it as a first dose. And in Germany this has been extended to everyone under-60.
Britain's medical regulator has said under-30s should be offered an alternative to AstraZeneca's vaccine because of their comparably tiny risk of being hospitalised or dying if they catch the virus.
But people in this age group who have already had AstraZeneca should still receive it as a second dose because there is no evidence of blood clots occurring after this shot.
Denmark will SWAP unwanted AstraZeneca jabs after ditching it entirely .
Denmark's health minister Magnus Heunicke confirmed on Monday that discussions were taking place between Denmark and other nations over vaccine swaps, but did not say with whom.Meanwhile, it was announced by the Swedish Health Agency on Tuesday that Swedes under 65 who have had one shot of the AstraZeneca vaccine will be given a different vaccine for their second dose.
