Setting the Record Straight on COVID Variants and Reinfections

The blitz of Omicron variants has felt like one long wave. And many questions have arisen amid the tumult. Are we seeing the emergence of entirely new coronavirus variants that are impervious to immunity from vaccines and previous infections? If we keep getting reinfected, is it inevitable that most of us will end up developing long Covid?

In short, the answer is no.  As a virologist, it’s important to me that people understand Covid-19 remains a great concern. But this does not excuse or license a misdiagnosis of the current situation.

Let’s start with what is true. BA.5, one of the most recent Omicron variants to emerge, is everywhere. It unquestionably has an advantage in terms of transmissibility over previous Omicron lineages, most likely because it’s better at evading our existing repertoire of antibodies. BA.5 and its close cousin BA.4 have a key mutation that enables them to sneak past an important class of so-called broadly neutralizing antibodies. These particular antibodies did a great job of preventing infections from a wide swath of earlier variants.

In recent weeks I’ve watched many vaccinated friends and family members get infected with the coronavirus for the first time. The most concerning of these are cases like a colleague of mine who was infected in May and again in June, both times becoming ill.

Thankfully, reinfection a few weeks after recovery is not the norm. Scientists have shown that people who previously contracted Covid-19 are less likely to get infected with the variant du jour than people who had never seen the virus, and this trend holds true for Omicron. Early research from Qatar that has not yet been peer-reviewed showed that people who had a BA.1 infection in, say, January were significantly less likely to experience a BA.4 or BA.5 breakthrough infection months later. While more research on this is welcome, these findings are consistent with how immunity, played out at the population level, helps explain the rise, fall and magnitude of epidemic waves.

Antibodies remain a powerful defense against this coronavirus. They do many things to protect us, while also flagging the virus for destruction by other elements of the immune system. Even though some studies have found that Omicron variants may induce weaker antibody responses than earlier variants, this is most likely because Omicron causes less severe disease, thanks to immunity from vaccines and prior infections.

Our immune system works much like a wise yet frugal investor, calibrating responses according to the magnitude and extent of the various danger signals sensed during infection. Generally speaking, the greater the symptoms and disease from infections like Covid or the flu, the stronger the antibody response. When existing antibodies are good enough to keep disease to a minimum (because fewer virus particles succeed in replicating in the body), we tend to see much lower amounts of antibodies than when someone ends up hospitalized from the coronavirus. Vaccines are a great way around that problem: They stimulate our immune systems to make antibodies, and other tailored defenses, even when there is no disease.

Right now the immunological makeup of the population is a mix. People who were infected with prior variants may now be catching Omicron infections, even if they’re also vaccinated. People who have never had Covid may be getting it now. It’s true that some people who got infected from an earlier Omicron variant in December, January or even more recently are catching BA.5 now, and becoming sick from it.
Alas, this current situation, where some are newly susceptible to infection while others remain protected, is no friend to nuance. It’s difficult to generalize broadly and make bold predictions concerning how well an individual or a population will hold up against infection now or later. But despite Omicron’s knack for circumventing antibodies, it’s clear that prior immunity, be it from vaccines or previous infections, protects from severe outcomes such as death and hospitalization. There has yet to be a variant that negates the benefits of vaccines.
Recently, an early study, which was not peer-reviewed, argued that reinfections are just as dangerous as primary infections, but there is by no means a consensus on this among scientists and medical experts. (The study only really showed that getting reinfected is worse than not being reinfected.) Other scientists are concerned about the long-term risks of multiple reinfections. However, there is no debate that prior immunity, in most cases, reduces the severity of subsequent infections. Catching the coronavirus more than once or after vaccination does not necessarily put someone at risk for the most serious and chronically debilitating forms of long Covid, though more research is needed to understand what might predispose someone to that.
The Food and Drug Administration should move swiftly to authorize new booster shots that target Omicron variants. The existing data suggest that updated shots, even based on earlier Omicron lineages, would be more effective at preventing infections than continuing to use the current vaccine boosters, which are based on the original 2019 coronavirus spike.
In the meantime, if you are eligible, it’s wise to get boosted with the currently available shots, which are still outstanding at preventing hospitalization and death. (This is especially critical for older people.) Wearing a mask when mixing indoors and avoiding indoor dining when case numbers are high remains advisable for those who’d prefer not to kick the tires on their existing immunity. Fortunately, monoclonal antibody cocktails are available that remain effective against BA.5. One such product, Evusheld, is given prophylactically to protect patients, while others are used to treat severe infections. Paxlovid, which can be taken at home, may also be a good option for people who test positive and are eligible for it.
Most immunologists I know are cautiously optimistic about our long-term prospects. We don’t know exactly what this virus will do next, and we should never be dismissive of those who have a high risk profile or are dealing with long Covid. Nonetheless, most of us can have faith in our immune systems, especially when we make use of vaccines and boosters. Recorded history may hold little precedent for the ongoing Covid-19 pandemic. But this is not our immune systems’ first rodeo.

Hewitt Inducted Into Hall Of Fame

It has been an emotional weekend for Lleyton Hewitt. Surrounded by family and friends in Newport, the Australian has relived his growth from a boy with a dream in Adelaide to one of tennis’ greatest champions in recent memory. On Saturday evening, that culminated in his induction into the International Tennis Hall of Fame.

“The Hall of Fame seemed like something that was so far away from me ever being part of,” Hewitt said during the induction ceremony. “It was never something I ever thought about as a player, and it was always, I thought, for the people that were my idols growing up and the absolute legends of the sport.”

In a stirring induction speech, the 41-year-old took fans from around the world through his journey to the podium in Rhode Island. When Hewitt was a boy, his favourite sport was AFL football, which was played by members of his family, including his father, Glynn Hewitt.

But following a period of research, Hewitt’s parents found a tennis coach for their son in Peter Smith, who had a weekly slot available at 7:30 a.m. on Sunday mornings. “Rusty” never looked back.

One of the most important meetings of his life came as a teen, when he was introduced to Australian legend John Newcombe at his camp in Texas. Hewitt asked to interview Newcombe for a school project.

“The biggest thing he told me was about the famous Kipling poem ‘If’, and especially about the famous two lines that are written above the walkway out on Centre Court at Wimbledon,” Hewitt said. “If you can meet with triumph and disaster and treat those two imposters just the same.”

No matter the hurdle Hewitt faced or the high he celebrated, the Australian gave his all. Regardless of the challenge, he tried his best to meet and exceed it.

Hewitt became the youngest No. 1 in Pepperstone ATP Rankings history at age 20 in 2001. The gritty right-hander captured two major singles titles, two year-end No. 1 finishes, two Nitto ATP Finals trophies and led Australia to two Davis Cup titles.

Before Roger Federer, Rafael Nadal and Novak Djokovic ascended to the top of the sport, Hewitt held top spot for 80 weeks, good for 10th-most in history. Even when those stars made their mark, “Rusty” scratched and clawed, proving he would never back down.

“I feel fortunate that I was able to play across different generations,” Hewitt said. “I was able to be on the same court as my heroes that I looked up to, like Andre Agassi and Pete Sampras, and then go on and compete against three of the greatest tennis players our sport has ever seen in Roger Federer, Rafael Nadaland Novak Djokovic.”

Hewitt was introduced by Australian legends Newcombe and Tony Roche, the latter of whom flew across the world to join his mentee for a special weekend.

“The first meeting I had with Lleyton was at a charity event in Adelaide,” Roche said. “He must have been 12 or 13. I was even impressed with his game at that early age. I was more impressed with his mullet haircut really. All the Adelaide kids seemed to have these great mullet haircuts. But Lleyton, you could tell, was going to be something special.”

A Good String Job Can Manage Your Limitations | AskThePro

In our previous column on rackets, we make reference to the key advantages of a good restring in managing your limitations!

The tournament pros are absolutely fanatical about their choice of strings and the associated string tension — which they change to suit both surface and playing conditions — and often during a match.  I still carry two rackets in my bag each with a slightly different tension to accommodate the changing playing conditions at Manly Lawn.

Conversely, our average tennis player puts what I euphemistically call “two dollars worth of nylon” in a $200+ high performance frame — and expects to play consistently well and without injury, especially tennis elbow.

Most club players who play two or more times a week are well advised to get a GOOD STRING JOB every 8 to 10 weeks depending on the season.  Aggressive players who blast the ball with big western forehands need to update every 3 to 4 weeks or so.  Yep, strings go loose and dead — and performance suffers!

Trust me when I say, your game will improve at least a POINT A GAME with a good restring! You might even be encouraged to take a few lessons to help better manage the rest of your limitations.

So what constitutes a GOOD STRING JOB?

First a little science education since modern strings come in different materials and thicknesses, each designed to suit different playing styles. In the table below, you’ll notice the differences in the main and cross strings and the dependence on whether you want control, power, comfort (did I mention managing tennis elbow?).

Thickness is pretty screwy since 18 gauge string is thinner than 16 gauge, go figure!

You can see from the graph above that the typical $2 nylon (16G) has high durability (to ensure rackets have a good shelf life) and low spin potential ( aka “feel/control”)! How did that new Wilson play with the $2 nylon strings?

Even at my tender age, I still use a hybrid combination of 18G multifilament Gamma Live Wire on the mains and Babolat Blast (Nadal’s string) on the crosses. Yep as I’ve aged and reverted to social player status, I’ve gone for more control and less power by reversing the mains and the crosses per the table. The 18G Live Wire is more lively (plays like gut) and gives me much more feel. The Blast allows me to give the ball a nudge and more topspin when I need to.

And now the string tension.  Most players string the crosses the same as the mains and expect the tension to be even itself out throughout the racket during stringing. Well that’s the logic anyway. The GOAL was always to get an even string tension in the racket to increase the ‘sweet spot’. Yep, for most of my playing life I relied on that logic too. Of course my ball watching was so much better than, and I played with gut, so miss hits were infrequent. And yep it’s SOoooooo Wrong!

Several years ago I ran into a older, chain smoking racket stringer in California who set me straight — and he didn’t hold back!  Turns out that what most people miss is the impact of FRICTION on the Crosses when you’re feeding the string under and over through the Mains. Whatever tension you string the Mains at, you ADD 5lb to the Crosses to counter the friction. Here’s my current stringing pattern to illustrate this key point:

 

So Obi Wan how should I translate this to my game? Well most rackets come with a suggested stringing guide for tension. Start with the mid range for the racket for the Mains and then string the Crosses 5lb more.  Then adjust up and down as required until you’re comfortable with the tension. Aside, typically you can use a lower tension that the one you used previously; helps your feel and control.

Just ask Tommie for ‘Rob’s restring’ if you want to try this type of restring at the Manly Tennis Centre. You’ll find an immediate benefit of a bigger sweet spot — and most of your misshits will go over now as your control is significantly improved.

As for the choice of string, well that depends on your game. I’ve given you the guidelines in the table above which you can probably figure out yourself. Even so, probably better to go talk to Scottie when you want some pro advice about what strings may suit your individual playing style. Or ask me.

To repeat you’ve got to manage your limitations — and using better technology (whether frame and/or strings) is a great way to do this. Cunning and guile will only get you so far! Invest in the technology!

Make a regular investment in a GOOD STRING JOB using the latest materials technology; it’s absolutely worth it for your psyche alone!

Sincerely,
Tennis Whisperer

Djokovic Defeats Kyrgios For 7th Wimbledon Title | ATP

Novak Djokovic produced a returning masterclass to surge to a 4-6, 6-3, 6-4, 7-6(3) victory against Nick Kyrgios in Sunday’s final at Wimbledon, where the top seed claimed his fourth consecutive crown at the grass-court major. 

Rallying from dropping the first set for the third straight match, Djokovic claimed a seventh title to draw level with Pete Sampras‘ mark at the All England Club. The 35-year-old Djokovic is now just one behind Roger Federer’s record of eight Wimbledon triumphs, and one Grand Slam title behind Rafael Nadal’s record of 22 major crowns. 

“I have lost words for what this tournament, this trophy means to me, my team, my family,” said Djokovic at the trophy presentation. “I’ve said this many times. It always has been and always will be the most special tournament in my heart, the one that motivated me, inspired me to start playing tennis in a small mountain resort in Serbia where my parents used to run a restaurant. 

“I was four or five years old and I saw Pete Sampras win his first Wimbledon in 1993. I asked my Dad and Mum to buy me a racquet, and my first image of tennis was grass and Wimbledon. I always dreamed of coming here, just playing in this court, and then realising the childhood dream of winning this trophy. Every single time it gets more meaningful and more special, so I’m very blessed and very thankful to be standing here with the trophy.” 

Most Grand Slam Titles 

Player Grand Slam Titles 
Rafael Nadal  22 
Novak Djokovic  21 
Roger Federer  20 
Pete Sampras  14

After some scintillating Kyrgios shotmaking took him to the opening set on Centre Court, Djokovic found his rhythm on return to take the upper hand in an intriguing clash of game styles. Despite his opponent firing 30 aces in a three-hour, one-minute encounter, the top seed was clinical in taking his chances, most notably when he crucially broke Kyrgios’ serve after the Australian had led 40/0 at 4-4 in the third set. A nerveless showing from Djokovic in the fourth-set tie-break, his first of the tournament, sealed the victory and extended his winning streak at SW19 to 28 matches. 

Although his ability to counter Kyrgios’ huge serving was key to Djokovic’s win, the Serbian was just as efficient with his own delivery. The top seed fired 15 aces and won 83 per cent (62/75) of points behind his first serve, compared to Kyrgios’ 70 per cent (64/91).

It marks another hard-fought triumph for Djokovic this week in London, where he overhauled a two-sets-to-love deficit to defeat Jannik Sinner in the quarter-finals and rallied from dropping the first set to Cameron Norrie in the semi-finals. The Serbian also defeated Soonwoo Kwon, Thanasi Kokkinakis, Miomir Kecmanovic and Tim van Rijthoven this fortnight in London.


DO WE LIKE KYRGIOS? IT’S COMPLICATED | SMH

Wimbledon still has a couple of days to go, which is helpful because 48 hours gives us time to have another 48 opinions on Nick Kyrgios, to add to the thousands we’ve had on Kyrgios over the past eight years. This is Australia in 2022: Girt By Nick. 

Kyrgios is now a human hottake generator, in that the endless hot takes on him now generate their own hot takes about the earlier hot takes, and on and on until we die. You’re reading one right now, so please watch for any sudden change in your vital signs. 

To sum up our rollercoaster journey with the tennis terror from Canberra, let’s go to the social media-speak Nick himself loves so much: It’s Complicated. WTAF. FFS. And so on. 

Because let’s be honest: it’s as easy to write the column ‘‘ Ten Reasons To Love Nick Kyrgios’ ’ as it is to write the column ‘‘ Ten Reasons To Hate Nick Kyrgios’’ . 

You can sensibly and sarcastically wonder out loud what it is the Kyrgios fans love about him. Is it the verbal abuse? The violent treatment of racquets and balls? The spitting? The tanking? The narcissism? Equally, you can ask the Kyrgios haters what it is they hate. Is it the breathtaking talent? The shotmaking audacity? The charming impudence of his approach to the game’s stuffed shirts? His refreshing honesty that winning isn’t everything? What’s not to love? And what’s not to hate? 

Kyrgios contains multitudes, and it is entirely possible that by Monday he will also contain a Wimbledon title, a triumph that will challenge us to reconsider him once again. Rarely have Australian sports fans been presented with a dilemma quite like the one we face this weekend. 

As a lifelong tennis nut, my own journey with Kyrgios has been long and complicated. I remember the time he first made me sit up with a start in the middle of the night, saving nine match points on his way to the Wimbledon quarter-finals in 2014. Everything seemed possible then. I loved the guy, and I’ve spent a lot of money supporting him, flying to Darwin to watch him in the Davis Cup, and finding myself sitting next to Ken Rosewall at Rod Laver Arena the night Kyrgios played Nadal at the Australian Open in 2020. 

Rosewall (who seemed bemused by Kyrgios more than anything else) never won Wimbledon, but he was a living reminder of a time when Australians always did. From 1922 to 1972, Australian players hoisted the men’s trophy 18 times. In the 50 years since, we’ve managed it just twice, Pat Cash in 1987 and Lleyton Hewitt in 2002. 

We desperately want another man to win the greatest title, but Kyrgios – with as much raw talent as any Australian player has ever had – complicates the hope. And some of that is actually quite simple for some of the reactions: it’s racism. But racism does not explain all or even most of the contentious relationship. 

I fell off the Kyrgios bandwagon last year, and after eight years of ferocious loyalty I’m finding it very hard to get back on it – even with a Wimbledon title in sight. The eternal promise had given way to eternal complaining. The bad behaviour too often crosses the line. The self-aggrandisement – the boasting about his crowd sizes and his self-proclaimed stature as the saviour of modern tennis – almost echoes Trump in its narcissism. 

And so here we are, wondering what comes next. 

Perhaps we can look to the past to summon some optimism. Hark back to John McEnroe, who was literally persona non grata at Wimbledon (they refused him the honorary club membership given to all champions) until his genius and his grit turned him into a beloved elder of the sport. 

Ditto with Andre Agassi. He even boycotted Wimbledon for years because of the all-white dress code. Then he turned up, wearing white tracksuit pants like a spirit returned from the 1920s, and won the whole show. Agassi 2.0 was born right there on the hallowed London lawns, past demons cast aside. 

Could history repeat? Will we come to love Kyrgios like we did those tennis toddlers of the past? We’re about to find out if Nick can wake up to the fact that the grass really is greener on the other side.

WIMBLEDON’S STRICT DRESS CODE IS NOT ALL-WHITE | SMH

In 1949, a 26-year-old American tennis player called Gertrude ‘‘ Gussie’’ Moran qualified for Wimbledon for the first time in her career. To mark the occasion, she asked the era’s most renowned designer of tennis dresses and longtime tournament ambassador, Teddy Tinling, to make her a bespoke outfit . The dress had to abide by Wimbledon’s all-white dress code, as enforced by the All England Lawn Tennis and Croquet Club. But that’s pretty much where tradition ended. Moran’s dress was cut above the knee, to allow for greater movement on the court. For many spectators that was outrageous enough, but it was Moran’s silk underwear with two inches of lace that really scandalised British high society.
It was an era before television, and photographers had chosen to lie on the ground behind Moran, hoping to capture pictures of her underwear as she served. The published images provoked an extraordinary backlash. Wimbledon also banned short dresses and the precursor tournament to the US Open prohibited lace underwear and revealing necklines. Moran never wore the dress again, but she could never shake off her reputation as ‘‘ Gorgeous Gussie’’ , the woman who shocked the tennis world.
In a sign of how even the most staid traditions can shift over time, in modern tournaments tennis dresses cut above the knee aren’t just allowed, they’re ubiquitous. But Wimbledon’s all-white rule remains, and it’s back in the spotlight after Australian Nick Kyrgios was pulled up for daring to wear red sneakers and a red hat after the conclusion of his fourth round match.
Rules governing how much, or how little, skin an athlete can show, and what colour their underwear is, seem deeply bizarre in 2022, but they’re in line with the history of Wimbledon and its traditions. The reason the all-white dress code was introduced was to avoid unsightly sweat patches on coloured clothes. It’s a concept that fits within the conservative Victorian social norms of the era in which Wimbledon was first played, but it’s unclear why so many feel wedded to retaining it now.
‘‘ Tradition’’ sounds appealing until you interrogate the political and social context it actually stems from, what values those enforcing it are trying to retain, and how it’s impossible to separate out fashion from the broader issues around gender and class. The ‘‘ tradition’ ’ argument also doesn’t really stack up considering the other Victorian-era rules that have been abandoned in recent years.
For decades the official Wimbledon championship board only listed women winners by their husband’s name, even if they had since separated or divorced. Maintaining some kind of dress code gives Wimbledon a distinctness that acknowledges its history, similar to all white Test cricket uniforms. But enforcing a policy around what shoes a player can wear once they finish their match can seem about more finding excuses to punish athletes than creating a particular fashion culture.
