Unveiling the Current Pandemic Predicament with Michael Osterholm
Just as we find ourselves smack-dab in the middle of history's deadliest pandemic in America, I had a chat with Michael Osterholm, a man who's been issuing warnings about the dangers of global pandemics for over a decade. He's a prominent member of Joe Biden's Presidential Transition COVID-19 Task Force.
Covid-19's relentless onslaught never fails to catch us off guard, with curveballs barreling towards us at 210 miles per hour. According to Osterholm, attempting to predict the future of this pandemic is like trying to foresee the path of a crystal ball smeared with 5 inches of hardened mud.
Our conversation, for the sake of clarity, was edited and his views are entirely his own.
Bergens: The White House recently predicted up to 100 million cases by autumn, while the Centers for Disease Control and Prevention only recommended mask-wearing in public transportation earlier this month.
Osterholm: Yes, it's a significant moment in the Covid-19 situation for the public. They've witnessed recent statements indicating that we're experiencing the negative consequences of the pandemic.
Bergens: These statements were by Ph.D. Anthony Fauci.
Osterholm: Yes, his comments were largely interpreted as an indication that the pandemic was over. I'm well aware that he was referring to surpassing the peak of cases, which is indeed true.
Bergens: He later retracted this statement shortly thereafter.
Osterholm: On the other hand, I don't see any data indicating a potential fall or winter surge of cases in the US leading to 100 million cases. Nobody should make such a statement without disclosing the underlying assumptions. While it's possible, it's more likely if a new variant emerges, one that's even more infectious than Omicron and better able to bypass existing immunity. Every model older than 30 days largely relies on fairy dust. I think the White House may have overstepped in that regard, but I understand the need to emphasize the need for Covid-19 relief funds.
I wholeheartedly support the government's efforts to secure additional funds for Covid-19 relief, but this money must be used effectively. Currently, we don't need more vaccine doses; we have plenty. What we truly need is for people to be fully vaccinated. By my definition, that means receiving at least three doses of the vaccine. Only 30% of Americans have received three doses, and this figure has barely changed in recent months.
The main focus of the government's request for additional support is the need for vaccine variants. However, vaccines developed against the Omicron subvariant may be less effective against emerging variants.
If we consider the future of this virus, we must factor in waning immunity. How long since the last booster, booster shot, or infection? Nobody knows what the effects of waning immunity will be in the coming months. We must be humble and honest about this.
At present, we see a rise in cases, but I believe that this is significantly underreported due to the widespread use of home rapid tests, which are largely excluded from the official case count.
If you examine hospital admissions, the increase is so far relatively small compared to previous surges. With regard to deaths, the discrepancy is more pronounced. Today, the US sees roughly 325 Covid-19 deaths per day. At the peak of the Omicron surge, that figure was 2,600 daily, and during the Delta surge, it was about 2,000 daily. We're now entering a new phase of the epidemic.
With variants like BA.2 and BA.2.12.1, an immune response to a previous infection, a past vaccine dose, or both can provide protection against a later infection. This means that we're seeing fewer severe cases, and it's not the same pandemic we experienced 18 to 24 months ago.
The problem now is that things could change tomorrow. We're still struggling to understand the implications of Omicron subvariants BA.4 and BA.5. Both varieties have become dominant in South Africa, and while cases are rising, they're also mild. In many cases, individuals affected have previously had Covid-19. The data suggest that geographically vaccinated South Africans with a prior infection may have the best protection against BA.4 and BA.5.
I keep hearing people say, "It's so contagious, nothing can stop it," but it will never reach light speed. We can certainly expect new variants to survive and exploit the process of microbial evolution by increasing infectiousness.
In summary, the issue of waning immunity is an often-overlooked one, but the point is that we don't know what will happen in six months. Will we hit 100 million cases? Possibly, but if we don't see new variants, that may not be the case. I think we must be humble and hope for the best while preparing for the worst.
The impacts of this virus on us are far from over. This virus will continue to spread for some time.
A recent development has served as a sobering reminder of the challenges we face: Taiwan announced that it would no longer maintain its zero-Covid policy. Omicron subvariants are like the wind – they can change direction, but you can't stop them.
Taiwan acknowledges that it can no longer control Omicron. We must realize that we're now living with this virus, and no one has the perfect plan to eliminate it. If, in the past two years, everyone suggested to me, "If we did it like China, or if we did it like Taiwan, we could control it," they were sorely mistaken.
After all, nobody has the perfect solution to combat this virus anywhere in the world.
Chinese President Xi Jinping remains firm in his commitment to China's zero-Covid policy. However, if his goal is to demonstrate the Chinese government's power in suppressing the virus, that's definitely counterproductive. Look at what's happening in Shanghai. They started locking down, then relaxed, and now they're locking down again. China is a clear example of where this won't work.
At the same time, we can't afford to let our guard down, which is why vaccination remains crucial. Antiviral medications for high-risk individuals with severe Covid-19 are also a vital aspect of our response.
Bergens: What's the status of vaccination among children under 5 years old?
Osterholm: I think we should accommodate them. We've transmitted Covid-19 to parents, grandparents, and other family members in schools and daycare centers. If we can reduce transmission in this demographic, it will likely have a domino effect.
It's worth noting that over 400 children under 5 have died from Covid-19 in the US.
Many parents of young children will say, "Oh, it's just an experiment. I'll wait another minute. My child has a low risk of becoming seriously ill," but if the vaccine is approved for use in children under 5 in the near future, we may see limited acceptance before schools reopen in the fall.
Bergens: Should people receive a second booster, if they're over 50 or immunocompromised?
Osterholm: The entire topic of boosters will be a challenge. What's going to happen in the fall for those who received their booster shots in the spring and summer? I have no idea.
Data suggest that people who received mRNA vaccines like those from Pfizer and Moderna will need periodic boosters, but that will be a significant challenge. Let's take a look at the third dose first. The latest data I've seen indicate that only 46% of people who received two vaccine doses have also received their third dose.
These aren't vaccine-hesitant people. We need to better understand why they haven't received their third dose and consider whether absorptive capacity improves after the fourth dose. What if we need a fifth dose?
Therefore, I think we need to take a step back and consider what our mRNA vaccines are capable of, and prepare for the possibility of completely new variants. If we take the specific Omicron-variant vaccine and a new variant emerges, will we suffer a setback?
We're fortunate that the number of daily deaths has significantly dropped, but if you're at high risk – over 65, overweight, diabetic, or have high blood pressure – these factors contribute to severe illness. The vaccine certainly provides a significant protective benefit, but I know numerous young, otherwise healthy colleagues who have recently been sick for seven to ten days, even though they were fully vaccinated with a booster shot.
The additional challenge is now that people want to resume their normal lives and live like before the pandemic. But what would people do if they saw . new variants? Would they be willing to adjust, isolate, or distance themselves? I doubt it at the moment.
Bergens: Did you participate in the White House press corps dinner?
Osterholm: I wasn't invited, and if I was, I wouldn't attend. I've never been to an event like that in the inner sanctum.
Bergens: Is the White House Correspondents' Dinner an imminent disaster? Osterholm: Certainly, yes. This isn't just a press event. It's surrounded by people from all walks of life.
