Brain Cells, Slime Mould, and Sentience Semantics
Recent media reports have highlighted a study suggesting that so-called “lab grown brain cells” can “play the video game ‘Pong’”. Whilst the researchers have described the system as ‘sentient’, others have maintained that we should use the term ”thinking system” to describe the system that the researchers created.
Does it matter whether we describe this as a thinking system, or a sentient one?
Cross Post: Vaccine Mandates For Healthcare Workers Should Be Scrapped – Omicron Has Changed The Game
Written by Dominic Wilkinson, Jonathan Pugh and Julian Savulescu
Time is running out for National Health Service staff in England who have not had a COVID vaccine. Doctors and nurses have until Thursday, February 3, to have their first jab. If they don’t, they will not be fully immunised by the beginning of April and could be dismissed.
But there are reports this week that the UK government is debating whether to postpone the COVID vaccine mandate for healthcare staff. Would that be the right thing to do?
Vaccine requirements are controversial and have led to worldwide protests. Those in favour have argued that it is necessary and proportionate to protect vulnerable patients by making vaccination a condition of employment for healthcare staff. But critics have argued that vaccine mandates amount to a violation of human rights. Continue reading
Cross Post: Why the UK Shouldn’t Introduce Mandatory COVID Vaccination
Written by Julian Savulescu, Dominic Wilkinson, and Jonathan Pugh
As coronavirus infections surge across Europe, and with the threat of the omicron variant looming, countries are imposing increasingly stringent pandemic controls.
In Austria, citizens will be subject to a vaccine mandate in February. In Greece, meanwhile, a vaccine mandate will apply to those 60 and over, starting in mid-January.
Both mandates allow medical exemptions, and the Greek mandate allows exemptions for those who have recently recovered from COVID.
Other countries, including Germany, may soon follow suit, and the European Commission has raised the need to discuss an EU vaccine mandate. In contrast, the UK health secretary, Sajid Javid, has been clear that the UK will not consider a general mandatory vaccination policy. Continue reading
Cross Post: Omicron: Better To Be Safe (And Quick) Than Sorry
Written by: Dominic Wilkinson, and Jonathan Pugh
These measures have tangible costs, and some have argued that they are an over-reaction. Critics of the travel ban claim that new measures will not significantly prevent the spread of the variant. Indeed, World Health Organization (WHO) officials have urged countries not to hastily impose travel curbs, instead advocating a risk analysis and science-based approach. Continue reading
Cross Post: Selective lockdowns can be ethically justifiable – here’s why
Written by: Jonathan Pugh, Dominic Wilkinson, and Julian Savulescu
Some countries already have vaccine passport schemes to travel or enter certain public spaces. The passports treat those who have had vaccines – or have evidence of recent infection – differently from those who have not had a vaccine. But the proposed selective lockdowns would radically increase the scope of restrictions for the unvaccinated.
Lockdowns can be ethically justified where they are necessary and proportionate to achieve an important public health benefit, even though they restrict individual freedoms. Whether selective lockdowns are justified, though, depends on what they are intended to achieve. Continue reading
COVID: Why We Should Stop Testing in Schools
Dominic Wilkinson, University of Oxford; Jonathan Pugh, University of Oxford, and Julian Savulescu, University of Oxford
Education Secretary Gavin Williamson has announced the end of school “bubbles” in England from July 19, following the news that 375,000 children did not attend school for COVID-related reasons in June.
Under the current system, if a schoolchild becomes infected with the coronavirus, pupils who have been in close contact with them have to self-isolate for ten days. In some cases, whole year groups may have to self-isolate.
Such mass self-isolation is hugely disruptive. Yet despite the clamour to switch to other protective measures, such as rapid testing of pupils who have been in close contact with an infected pupil, the public service union Unison has supported self-isolation as “one of the proven ways to keep cases under control”.

Pfizer Jab Approved for Children, but First Other People need to be Vaccinated
Dominic Wilkinson, University of Oxford; Jonathan Pugh, University of Oxford, and Julian Savulescu, University of Oxford
Moderna and Pfizer have released data suggesting that their vaccines are well tolerated in adolescents and highly effective in preventing COVID-19. Canada, the US and the EU have already authorised the Pfizer vaccine in children as young as 12. And the UK has just approved the use of the Pfizer vaccine in children aged 12 to 15. But there may a case for holding out on an immediate rollout, for several reasons.
Whether a vaccine is beneficial for someone depends on three things: how likely they are to become seriously ill from the infection, how effective the vaccine is, and the risks of vaccination. Continue reading
Crosspost: Learning to live with COVID – the tough choices ahead

As mass vaccination continues to be rolled out, the UK is beginning to see encouraging signs that the number of COVID deaths is reducing, and that the vaccines may be reducing the transmission of coronavirus.
While this is very welcome news, a mass vaccination programme is unlikely to be enough to eliminate the virus, so we need to turn our thoughts towards the ethics of the long-term management of COVID-19.
One strategy would be to aim for the elimination of the virus within the UK. New Zealand successfully implemented an elimination strategy earlier in the pandemic and is now in a post-elimination stage.
An elimination strategy in the UK would require combining the mass vaccination programme with severe restrictions on international travel to stop new cases and variants of the virus being imported. However, the government has been reluctant to endorse an elimination strategy, given the importance of international trade to the UK economy.
One of the main alternatives to the elimination strategy is to treat coronavirus as endemic to the UK and to aim for long-term suppression of the virus to acceptable levels. But adopting a suppression strategy for the long term will require us to make a societal decision about the harms we are and are not willing to accept.
Cross Post: There’s no Need to Pause Vaccine Rollouts When There’s a Safety Scare. Give the Public the Facts and Let Them Decide

For instance, reports of blood clots associated with the AstraZeneca vaccine led to several European countries suspending their vaccination programs recently, only to resume them once these clots were judged to be a coincidence. However, authorities couldn’t rule out increased rates of a rare brain blood clot associated with low levels of blood platelets.
There are also problems with the Pfizer and Moderna vaccines. By early February 2021, among the over 20 million people vaccinated in the United States, there have been 20 reported cases of immune thrombocytopenia, a blood disorder featuring a reduced number of platelets in the blood. Experts suspect this is probably a rare vaccine side-effect but argue vaccination should continue.
So what happens with the next safety scare, for these or other vaccines? We argue it’s best to give people the facts so they have the autonomy to make their own decisions. When governments pause vaccine rollouts while investigating apparent safety issues, this is paternalism, and can do more harm than good. Continue reading
Suspending The Astra-Zeneca Vaccine and The Ethics of Precaution

Summary Points
- Preliminary Reviews suggest that the number of thrombotic events in individuals who have received the Astra Zeneca vaccine is not greater than the number we would normally expect in this population.
- It is crucial that we closely monitor these adverse events. The regulation of new medical interventions always requires us to manage uncertainty.
- A precautionary approach to managing this uncertainty may be important for ensuring continued confidence in vaccination.
- Regulators must weigh the potential risk suggested by these reports of adverse events following vaccination against the harm that suspension of the vaccine could have.
- The harm of suspending the use of the Astra Zeneca vaccine depends on how many preventable deaths we can expect by suspending its use.
- Amongst other things, this will depend on (i) how many people will be delayed in receiving a vaccine as a result (ii) the mortality risk of the people who would be prevented from receiving a vaccine, (iii) the prevalence of the virus at the time of the suspension, and (iv) the number of people who have received one dose of the Astra Zeneca vaccine, but not a second.
