Related: From alcohol to virus shedding, six dos and don'ts after getting vaccinated
The long-term mixing of different Covid-19 vaccines is unlikely to be harmful – and could even provide better protection against the coronavirus, several top experts said.
Taking one type of vaccine today and a separate dose by another manufacturer a year down the line could become normal, particularly if the pandemic continues for years.
Several top scientists gave their expert view to The National as many people debate whether to take the first available shot or wait.
Although the six vaccines approved for use around the world were each tested on hundreds of thousands of people, inevitably some have a preference or have medical reasons to hold off for now.
“You shouldn’t need it, but you cannot be over-vaccinated, so any risk would be very low,” said Prof Ian Jones, professor of virology at the University of Reading in the UK.
The approved vaccines were extensively tested, but it remains unclear how long the protection they offer will last.
With the vaccines released so far, a booster injection is required within weeks of the first dose, but it may be that, beyond this, a further shot is needed to sustain protection.
Prof Jones said that if a person completed two doses of one vaccine now, and took a different coronavirus vaccine a year later, there were unlikely to be any risks.
But experts said they draw a sharp distinction between that practice and that of combining vaccines within a short space of time.
Prof Paul Hunter, professor of medicine and infectious diseases at the University of East Anglia, UK, said one drug could stimulate enzymes in the liver that break down another drug, making it less effective.
“Interactions are one of the things we hammer into medical students now,” he said.
“They have to be careful.”
If a booster is needed even later on, scientists say there may be an upside to using a different coronavirus vaccine.
Known as heterologous prime boosting, this phenomenon has been seen with vaccinations against numerous diseases.
“This has been known to greatly increase both antibody and T-cell immunogenicity when performed using certain vector combinations, above repeated dosing with the same vaccine candidate,” the World Health Organisation said in a 2014 briefing document.
Using the same vaccine repeatedly can lead the immune system to target the vaccine itself, reducing its efficacy.
An example is adenoviral vector immunity. This may affect the Oxford-AstraZeneca vaccine, which is based on a harmless form of an adenovirus that normally infects chimpanzees.
The adenovirus has had DNA added so that, once it enters human cells, it causes them to produce coronavirus spike proteins.
It is the body’s immune response to these spike proteins that offers protection against the coronavirus.
But if there is an immune response against the adenoviral vector itself, spike protein production on subsequent doses is hampered, and immunity fails to improve as it should.
“This might be why the AstraZeneca vaccine is not as effective as the other vaccines,” Prof Hunter said.
“You give the second dose and ... if the body has already developed some immunity to the carrier virus, it gets destroyed before it’s had a chance to insert its payload.”
Trials are under way to find out whether protection is stronger when a person receives one dose of the Oxford-AstraZeneca vaccine and one dose of Russia’s Sputnik V vaccine, which is based on a different adenovirus.
Immunity to the vaccine is thought to be less of a problem with the two mRNA vaccines, made by Pfizer-BioNTech and Moderna.
“We may well, if there are issues around people developing immunity to the carrier and we have to give boosters in a year or so’s time, deliberately switch vaccines,” Prof Hunter said.
“But we need to do a lot of work between now and then before we decide.”

How to keep control of your emotions
If your investment decisions are being dictated by emotions such as fear, greed, hope, frustration and boredom, it is time for a rethink, Chris Beauchamp, chief market analyst at online trading platform IG, says.
Greed
Greedy investors trade beyond their means, open more positions than usual or hold on to positions too long to chase an even greater gain. “All too often, they incur a heavy loss and may even wipe out the profit already made.
Tip: Ignore the short-term hype, noise and froth and invest for the long-term plan, based on sound fundamentals.
Fear
The risk of making a loss can cloud decision-making. “This can cause you to close out a position too early, or miss out on a profit by being too afraid to open a trade,” he says.
Tip: Start with a plan, and stick to it. For added security, consider placing stops to reduce any losses and limits to lock in profits.
Hope
While all traders need hope to start trading, excessive optimism can backfire. Too many traders hold on to a losing trade because they believe that it will reverse its trend and become profitable.
Tip: Set realistic goals. Be happy with what you have earned, rather than frustrated by what you could have earned.
Frustration
Traders can get annoyed when the markets have behaved in unexpected ways and generates losses or fails to deliver anticipated gains.
Tip: Accept in advance that asset price movements are completely unpredictable and you will suffer losses at some point. These can be managed, say, by attaching stops and limits to your trades.
Boredom
Too many investors buy and sell because they want something to do. They are trading as entertainment, rather than in the hope of making money. As well as making bad decisions, the extra dealing charges eat into returns.
Tip: Open an online demo account and get your thrills without risking real money.

Top tips to avoid cyber fraud
Microsoft’s ‘hacker-in-chief’ David Weston, creator of the tech company’s Windows Red Team, advises simple steps to help people avoid falling victim to cyber fraud:
1. Always get the latest operating system on your smartphone or desktop, as it will have the latest innovations. An outdated OS can erode away all investments made in securing your device or system.
2. After installing the latest OS version, keep it patched; this means repairing system vulnerabilities which are discovered after the infrastructure components are released in the market. The vast majority of attacks are based on out of date components – there are missing patches.
3. Multi-factor authentication is required. Move away from passwords as fast as possible, particularly for anything financial. Cybercriminals are targeting money through compromising the users’ identity – his username and password. So, get on the next level of security using fingertips or facial recognition.
4. Move your personal as well as professional data to the cloud, which has advanced threat detection mechanisms and analytics to spot any attempt. Even if you are hit by some ransomware, the chances of restoring the stolen data are higher because everything is backed up.
5. Make the right hardware selection and always refresh it. We are in a time where a number of security improvement processes are reliant on new processors and chip sets that come with embedded security features. Buy a new personal computer with a trusted computing module that has fingerprint or biometric cameras as additional measures of protection.

What is Reform?
Reform is a right-wing, populist party led by Nigel Farage, a former MEP who won a seat in the House of Commons last year at his eighth attempt and a prominent figure in the campaign for the UK to leave the European Union.
It was founded in 2018 and originally called the Brexit Party.
Many of its members previously belonged to UKIP or the mainstream Conservatives.
After Brexit took place, the party focused on the reformation of British democracy.
Former Tory deputy chairman Lee Anderson became its first MP after defecting in March 2024.
The party gained support from Elon Musk, and had hoped the tech billionaire would make a £100m donation. However, Mr Musk changed his mind and called for Mr Farage to step down as leader in a row involving the US tycoon's support for far-right figurehead Tommy Robinson who is in prison for contempt of court.

Tributes from the UAE's personal finance community
• Sebastien Aguilar, who heads SimplyFI.org, a non-profit community where people learn to invest Bogleheads’ style
“It is thanks to Jack Bogle’s work that this community exists and thanks to his work that many investors now get the full benefits of long term, buy and hold stock market investing.
Compared to the industry, investing using the common sense approach of a Boglehead saves a lot in costs and guarantees higher returns than the average actively managed fund over the long term.
From a personal perspective, learning how to invest using Bogle’s approach was a turning point in my life. I quickly realised there was no point chasing returns and paying expensive advisers or platforms. Once money is taken care off, you can work on what truly matters, such as family, relationships or other projects. I owe Jack Bogle for that.”
• Sam Instone, director of financial advisory firm AES International
"Thought to have saved investors over a trillion dollars, Jack Bogle’s ideas truly changed the way the world invests. Shaped by his own personal experiences, his philosophy and basic rules for investors challenged the status quo of a self-interested global industry and eventually prevailed. Loathed by many big companies and commission-driven salespeople, he has transformed the way well-informed investors and professional advisers make decisions."
• Demos Kyprianou, a board member of SimplyFI.org
"Jack Bogle for me was a rebel, a revolutionary who changed the industry and gave the little guy like me, a chance. He was also a mentor who inspired me to take the leap and take control of my own finances."
• Steve Cronin, founder of DeadSimpleSaving.com
"Obsessed with reducing fees, Jack Bogle structured Vanguard to be owned by its clients – that way the priority would be fee minimisation for clients rather than profit maximisation for the company.
His real gift to us has been the ability to invest in the stock market (buy and hold for the long term) rather than be forced to speculate (try to make profits in the shorter term) or even worse have others speculate on our behalf.
Bogle has given countless investors the ability to get on with their life while growing their wealth in the background as fast as possible. The Financial Independence movement would barely exist without this."
• Zach Holz, who blogs about financial independence at The Happiest Teacher
"Jack Bogle was one of the greatest forces for wealth democratisation the world has ever seen. He allowed people a way to be free from the parasitical "financial advisers" whose only real concern are the fat fees they get from selling you over-complicated "products" that have caused millions of people all around the world real harm.”
• Tuan Phan, a board member of SimplyFI.org
"In an industry that’s synonymous with greed, Jack Bogle was a lone wolf, swimming against the tide. When others were incentivised to enrich themselves, he stood by the ‘fiduciary’ standard – something that is badly needed in the financial industry of the UAE."

Gender equality in the workplace still 200 years away
It will take centuries to achieve gender parity in workplaces around the globe, according to a December report from the World Economic Forum.
The WEF study said there had been some improvements in wage equality in 2018 compared to 2017, when the global gender gap widened for the first time in a decade.
But it warned that these were offset by declining representation of women in politics, coupled with greater inequality in their access to health and education.
At current rates, the global gender gap across a range of areas will not close for another 108 years, while it is expected to take 202 years to close the workplace gap, WEF found.
The Geneva-based organisation's annual report tracked disparities between the sexes in 149 countries across four areas: education, health, economic opportunity and political empowerment.
After years of advances in education, health and political representation, women registered setbacks in all three areas this year, WEF said.
Only in the area of economic opportunity did the gender gap narrow somewhat, although there is not much to celebrate, with the global wage gap narrowing to nearly 51 per cent.
And the number of women in leadership roles has risen to 34 per cent globally, WEF said.
At the same time, the report showed there are now proportionately fewer women than men participating in the workforce, suggesting that automation is having a disproportionate impact on jobs traditionally performed by women.
And women are significantly under-represented in growing areas of employment that require science, technology, engineering and mathematics skills, WEF said.

Tomato and walnut salad
A lesson in simple, seasonal eating. Wedges of tomato, chunks of cucumber, thinly sliced red onion, coriander or parsley leaves, and perhaps some fresh dill are drizzled with a crushed walnut and garlic dressing. Do consider yourself warned: if you eat this salad in Georgia during the summer months, the tomatoes will be so ripe and flavourful that every tomato you eat from that day forth will taste lacklustre in comparison.
Badrijani nigvzit
A delicious vegetarian snack or starter. It consists of thinly sliced, fried then cooled aubergine smothered with a thick and creamy walnut sauce and folded or rolled. Take note, even though it seems like you should be able to pick these morsels up with your hands, they’re not as durable as they look. A knife and fork is the way to go.
Pkhali
This healthy little dish (a nice antidote to the khachapuri) is usually made with steamed then chopped cabbage, spinach, beetroot or green beans, combined with walnuts, garlic and herbs to make a vegetable pâté or paste. The mix is then often formed into rounds, chilled in the fridge and topped with pomegranate seeds before being served.

Why it pays to compare
A comparison of sending Dh20,000 from the UAE using two different routes at the same time - the first direct from a UAE bank to a bank in Germany, and the second from the same UAE bank via an online platform to Germany - found key differences in cost and speed. The transfers were both initiated on January 30.
Route 1: bank transfer
The UAE bank charged Dh152.25 for the Dh20,000 transfer. On top of that, their exchange rate margin added a difference of around Dh415, compared with the mid-market rate.
Total cost: Dh567.25 - around 2.9 per cent of the total amount
Total received: €4,670.30
Route 2: online platform
The UAE bank’s charge for sending Dh20,000 to a UK dirham-denominated account was Dh2.10. The exchange rate margin cost was Dh60, plus a Dh12 fee.
Total cost: Dh74.10, around 0.4 per cent of the transaction
Total received: €4,756
The UAE bank transfer was far quicker – around two to three working days, while the online platform took around four to five days, but was considerably cheaper. In the online platform transfer, the funds were also exposed to currency risk during the period it took for them to arrive.
