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


President Joe Biden examined constructive for Covid-19 over the weekend, simply days after testing adverse and resuming an everyday schedule of in-person conferences. It’s a traditional case of “rebound Covid,” one thing 1000’s 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 keeping with Vox senior well being reporter Keren Landman. For folks at excessive danger of extreme Covid illness or dying, the chance of a foul final result is significantly diminished by the remedy. The true drawback with rebound Covid is it dangers infecting others who are available contact with a person who has gone again out into the world after a adverse check. Biden, for instance, had Cupboard members and employees with him for conferences on the White Home and spoke to reporters indoors on Thursday, between his adverse and constructive 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 constructive.

Landman defined extra about Paxlovid rebound Covid final month on an episode of At present, Defined.

Right here’s Keren:

In case your endpoint is stopping extreme illness and dying in excessive danger people, [Paxlovid] continues to be doing nice. There’s no indication that it has fallen off in any manner, even with BA.5 on the scene. However it’s proving to be an incomplete remedy for controlling signs.

You in all probability heard that Anthony Fauci himself had what’s referred to as a rebound signs after taking Paxlovid. He mainly simply took a second course of Paxlovid and did high quality, 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 actual 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. However it appears simply from the anecdotal studies, like in the actual 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 that they had is giving them persistent signs that the Paxlovid was not sufficient to fully flip again. There’s some query about why that’s. Individuals are nervous: Does that imply that if I take these 5 days of Covid 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 counsel 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 might need gotten into. So I feel 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 otherwise in numerous folks as a result of our metabolism of medicine is totally different. I feel we’ll in all probability find yourself seeing the dosage that’s beneficial of this drug change as we be taught extra about how many individuals are experiencing this and and who want who may want a little bit bit extra of the drug with a view to fully deal with the viral an infection with Covid.

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