President Biden’s Paxlovid rebound Covid: How dangerous is it?

President Joe Biden examined optimistic for Covid-19 over the weekend, simply days after testing unfavorable and resuming a daily schedule of in-person conferences. It’s a basic case of “rebound Covid,” one thing hundreds of Individuals have skilled after taking a course of the antiviral drug Paxlovid, as Biden had.

How dangerous is rebound Covid to Biden and others who take Paxlovid? Not terribly, in response to Vox senior well being reporter Keren Landman. For individuals at excessive danger of extreme Covid illness or demise, the chance of a nasty final result is drastically decreased by the therapy.

The true drawback with rebound Covid is the chance of infecting others who are available in contact with a person who has gone again out into the world after a unfavorable check. Biden, for instance, had Cupboard members and workers with him for conferences on the White Home and spoke to reporters indoors on Thursday, between his unfavorable and optimistic checks. The White Home physician stated Saturday that Biden had no reemergence of signs, and the White Home stated that nobody who had been in shut contact with Biden had examined optimistic.

Landman defined extra about Paxlovid rebound Covid final month on an episode of As we speak, Defined.

Right here’s Keren:

In case your endpoint is stopping extreme illness and demise in high-risk of us, [Paxlovid] remains to be doing nice. There’s no indication that it has fallen off in any approach, even with BA.5 on the scene. However it’s proving to be an incomplete therapy for controlling signs.

You in all probability heard that Anthony Fauci himself had what’s known as rebound signs after taking Paxlovid. He principally simply took a second course of Paxlovid and did superb, as do most individuals who’ve these rebound signs. However he didn’t go to the hospital and clearly had no extreme final result from the an infection, as do, to my data, all individuals who have had rebound signs after a Paxlovid course. A part of fine-tuning a brand new drug is determining the way it works in the true world. In Pfizer’s trial, solely possibly 1 or 2 % of individuals had rebound signs after 5 days of Paxlovid for an early Covid an infection. Nevertheless it appears simply from the anecdotal reviews, like in the true world, there’s in all probability the next proportion of people who find themselves experiencing that. It in all probability goes to want some fine-tuning in the way it’s dosed and what we anticipate from it going ahead.

It’s not that the Paxlovid is giving [patients] an extra bout of Covid. It’s that the unique Covid that they’d is giving them persistent signs that the Paxlovid was not sufficient to utterly flip again. There’s some query about why that’s. Individuals are fearful: Does that imply that if I take these 5 days of [Paxlovid] and my signs come again, is it a super-Covid? Is that Covid stronger than it was earlier than as a result of it overcame these first 5 days, or is one thing else occurring?

Single-patient research recommend that’s not what’s occurring, that it’s actually simply that the viral an infection requires the next dose for an extended time, and even simply the identical dose for an extended time to get into all of the cells the place the Covid may need gotten into. So I believe it’s in all probability only a matter of the science of pharmacokinetics and the way medication get into your physique’s cells and take motion and the way they get eradicated by your physique. Medicine act in another way in several individuals as a result of our metabolism of medicine is completely different. I believe we’ll in all probability find yourself seeing the dosage that’s advisable of this drug change as we be taught extra about how many individuals are experiencing this and and who may want a bit bit extra of the drug as a way to utterly deal with the viral an infection with Covid.

[Paxlovid] has finished much more good than unhealthy. I imply, when you concentrate on what “unhealthy” Paxlovid may need finished, okay, it has some unintended effects. They’re typically fairly minor. I hear most in regards to the metallic style in individuals’s mouth, however in any other case it’s typically fairly effectively tolerated.
