UK hospitals use blockchain to trace coronavirus vaccine temperature

LONDON – Two hospitals in the UK are actively using blockchain technology to maintain the temperature of coronavirus vaccines before they are administered to patients.

The National Health Service facilities in South Warwickshire, England, use technology developed by the UK company Everyware and the US organization Hedera Hashgraph. Everyware uses sensors to monitor devices in real time, while Hedera is a blockchain consortium backed by Google and IBM.

Although blockchain was originally created as a digital ledger for Bitcoin, it has since been adapted by various industries for non-financial applications. For example, IBM and Walmart have used blockchain to track food supply chains and identify potential contamination.

Tom Screen, technical director at Everyware, told CNBC that its sensors would monitor the temperature of refrigerators that store vaccines. The data is then transferred to its own cloud platform, where it is encrypted and then forwarded to Hedera’s blockchain network.

The aim of this operation is to keep a tamper-proof digital record of temperature-sensitive vaccines such as those developed by Pfizer and BioNTech. In theory, hospitals could detect irregularities in the storage of vaccines before they are given to patients.

Pfizer’s vaccine must be stored at temperatures below zero (-70 degrees Celsius) and can only be kept for up to five days in conditions of two to eight degrees Celsius, which creates great logical hurdles for logistics in the distribution.

However, the vaccines developed by Moderna and Oxford-AstraZeneca can be stored at temperatures that are beyond the reach of the average household refrigerator for longer.

Blockchain saw a lot of hype in 2017 when the value of cryptocurrencies like Bitcoin skyrocketed. This led to several projects by large companies like IBM and Walmart, as well as governments promising to replace various old paper-based methods of recording.

Today, the craze for blockchain seems to have waned, and trials and products based on the technology are hardly announced by large companies.

When asked why blockchain is needed instead of a regular database, Everyware’s Screen said, “Data stored in a private database can be verified by the status of data recorded in the public ledger.”

“The benefits of having an immutable ledger to check the validity of data as close to the source as possible have a positive impact on the accuracy of the downstream analysis, which increases errors in the source data in the output records,” he said.

Everyware participated in an open tender process involving other bidders to provide its services to the South Warwickshire NHS Foundation Trust, Screen said.

UAE on observe to vaccinate half its inhabitants by finish of March

DUBAI, United Arab Emirates – The United Arab Emirates are on the way to vaccinate half of its population against the coronavirus before a deadline it set itself in late March, according to the country’s health authorities.

The little desert sheikh of 10 million began delivering its vaccination campaign to the public late last year after making China’s Sinopharm vaccine available to frontline health workers and government officials in September. In terms of vaccination rates, the UAE’s national program is the second highest in the world after Israel.

More than 1.8 million people have already received the Sinopharm vaccine, which is available to all citizens and residents free of charge. That is more than four times the vaccination rate per capita in the US. The Pfizer BioNTech vaccine developed in the USA and Germany is launched in Dubai. He is currently in the first phase, which is reserved for people over the age of 60, existing health conditions and frontline workers.

Both vaccines require two shocks 28 days apart, and 28 days after receiving the second shot, patients are no longer required to be quarantined but are required to continue wearing masks and practicing social distancing, as the country’s national emergency crisis and disaster management agency does did said

And while taking the vaccine is optional, it is highly recommended, according to NCEMA. Government employees in Abu Dhabi who choose not to take any of the vaccines are required to do a PCR test every two weeks.

“We are very pleased with the progress we have made,” UAE deputy minister for culture and public diplomacy Omar Ghobash told CNBC’s Hadley Gamble on Sunday. “Of course there are people who still get sick and sadly die, but overall we think we’ve managed to strike a balance between health and safety on the one hand and economic viability on the other.”

Sinopharm developers say the vaccine is 86% effective while the Pfizer / BioNTech vaccine is 95% effective, although some health professionals have expressed skepticism about the Chinese-made vaccine as there is no published data on its development and its Studies are available. In November, UAE leaders including the ruler of Dubai Sheikh Mohammed bin Rashid al Maktoum tweeted pictures of themselves receiving the Sinopharm shot.

The vaccinations progress below the peaks in some cases

Since late December, cases in Gulf Land have risen in less than three weeks as tourists flocked to Dubai’s fully open beaches, restaurants and shopping malls. Although visitors may require a negative PCR test result before boarding or upon arrival, many suspect that a transmissible strain of virus, first identified in the UK, is at least partly to blame for the large number of British tourists staying in the emirate on vacation.

The spike in cases – now averaging more than 3,000 a day compared to around 1,000 a day in late December – led the UK to remove the UAE from its “safe travel corridor” despite UK travelers being excluded from many countries for fear of the new strain of the virus . The UAE had successfully kept their case numbers below 2,000 per day for all of 2020.

The UAE has recorded 256,732 confirmed cases of the coronavirus and 751 deaths, according to Johns Hopkins University. A record number of 3,453 cases was recorded on Sunday.

Still, it seems that the party city and regional trade capital Dubai will continue their vaccination campaign, at least for the time being, while keeping their tourism-dependent economy open.

The neighboring oil-rich capital Abu Dhabi was now much more conservative and required a series of negative PCR test results over a period of several days for anyone wishing to enter the emirate – including from other emirates in the country.

In Dubai, the wearing of masks is still required in all public places, with the exception of activities such as eating or doing strenuous exercise. The authorities remind residents of social distance. The emirate’s openness, which has gradually increased since the summer, was due to one of the strictest lockdowns in the world in March and April.

Until the New Year, the Dubai government allowed residents to hold gatherings of up to 30 people in their homes. Hotels that were once almost empty now have an occupancy rate of over 70% as tourists flee their own countries for reasons of normalcy and warm weather.

“You balance personal responsibility with an economy that needs to move forward,” Ghobash said of the country.

“Vaccinate the largest percentage of society possible” is the country’s goal, NCEMA tweeted earlier this month, to “gain access to vaccine-acquired immunity that will help reduce the number of cases and control the disease” .

Apple could take away apps that observe customers with out permission in 2021

Craig Federighi, Apple’s senior vice president of software engineering, speaks during a new product announcement at the Apple Worldwide Developers Conference on Monday June 4, 2018 in San Jose, California.

Starting next year, Apple will be removing apps from its app store that are tracking users without prior permission. This promises to strengthen iPhone users’ privacy but is likely to shake the app advertising industry.

To target advertisements and measure their effectiveness, app developers and other industry players currently often use an IDFA (Identifier for Advertisers) or a sequence of letters and numbers that is different on each Apple device.

In an update to the iPhone operating system, which is expected “early next year,” app manufacturers must ask for permission to access a user’s IDFA via a popup. A significant proportion of users will likely choose to opt out, which will reduce the effectiveness and profitability of targeted ads. The change takes a privacy option that was previously buried in Settings and brings it to the fore when users open each app.

On Tuesday, Craig Federighi, Apple’s senior vice president of software development, said apps that do not meet the new requirements that Apple calls App Tracking Transparency (ATT) can be removed from the App Store. This is the only way to install software on an iPhone.

The move puts app developers who make money from targeted ads versus Apple, which has increasingly built privacy features into its products to set them apart from the competition. Among the critics is Facebook, which said the change could cut sales in one of its advertising stores by 50%.

“Some in the advertising industry are opposing these efforts, claiming that ATT will cause ad-supported businesses to suffer dramatic damage. However, as with the introduction of intelligent tracking prevention, we expect the industry to adapt and deliver effective advertising without invasive tracking “said Federighi in a speech at a European data protection conference.

Some examples of the tracking that Apple says app makers would need to get user permission first:

  • Show targeted advertisements in apps based on user data collected from apps and websites of other companies.
  • Share device location data or email lists with a data broker.
  • Share a list of emails, promotional IDs, or other IDs with a third-party ad network that will use the information to refocus those users in other developer’s apps or find similar users.

“Early next year we will need any apps that want to do this in order to get explicit permission from their users, and developers who do not meet this standard can have their apps removed from the App Store,” said Federighi.

The disclosure that Apple can remove non-compliant apps also raises the stake for a date expected early next year when app developers will have to specifically ask permission to use IDFA to perform tracking, forcing developers to rebuild part of their ad targeting systems to meet Apple’s requirements.

According to StatCounter, Apple’s iPhones make up just over 25% of smartphones worldwide, but the market share is higher in countries like the United States. In addition, iPhone users are often wealthier and viewed as more valuable customers. When app developers are removed from the app store, they lose a huge market.

Apple’s ATT is the latest in a series of steps reducing advertisers’ ability to collect data about iPhone users. In 2017, Apple introduced a feature called ITP that uses machine learning to block ad trackers in the Apple Safari browser. On Tuesday, Apple asked app developers to submit a detailed questionnaire about its privacy practices and the data they and third-party partners collect before being approved on the App Store.

Apple has been criticized on both sides of the IDFA issue. In France, advertising firms and publishers filed a competition complaint in October alleging that the proposed move away from IDFA is using privacy as cover for anti-competitive behavior to harm smaller tech companies.

Last month, Apple was also hit by complaints from activists in Europe that IDFA – the current system – did not comply with European data protection laws.

“We have postponed the release of ATT until early next year to give developers the time they have given to properly update their systems and data practices. However, we are still fully committed to ATT and our comprehensive approach to privacy obliged, “said Jane Horvath, senior data protection officer at Apple, replied.

Apple has not publicly announced when ATT will take effect.
