Covid-19 hospitalizations are on the rise in the United States, with more than 34,000 new admissions last week, but millions of vaccines and doses of antiviral treatments that could help prevent severe outcomes from the virus remain unused.

Research has found that many who could benefit most from the Covid-19 medication Paxlovid – including the elderly and Black and Hispanic people, groups that have disproportionately had the most severe illness – are less likely to take it.

As the supply of Paxlovid has grown, efforts have been made to improve timely, equitable access to the treatment.

“The driving distance to the nearest site or the geographic accessibility of the places where Paxlovid is being offered doesn’t seem to be the primary driver of why these populations are not getting the treatments they need,” said Dr. Rohan Khazanchi, a resident at Harvard Medical School and health equity consultant for the New York City health department.

Transportation is one significant barrier to health care access for many people, experts say, but creating equitable outcomes will involve a much more comprehensive approach.

In response to the White House’s call for pharmacies to help make this winter a healthier one for Americans, Walgreens launched a program Thursday in partnership with DoorDash and Uber Health that offers free home delivery of Paxlovid for those with a prescription. The initiative is meant to increase access to Covid-19 treatment, particularly for those in socially vulnerable or medically underserved communities.

Millions of Americans get prescriptions through the mail, a service that research has shown is used more frequently among seniors, adults with poor health and others who are also at high risk of severe outcomes for Covid-19.

But Paxlovid is most effective when taken within five days of symptoms starting, making timely treatment a critical piece of the puzzle and traditional mail-order delivery too slow.

Walgreens also plans to expand the service to include HIV treatment – in line with the Biden administration’s goals to accelerate efforts to end the HIV/AIDS epidemic in the US.

As with Paxlovid, early uptake is key with HIV treatment. And people who miss doses of HIV treatment risk developing drug resistance, making it crucial that they stick with the prescription.

“There are places across the patient journey that would divert a patient from being able to get treated and back to feeling better. But that’s where our teams have been working on really understanding that patient journey and then offering and identifying solutions to help address that,” said Rina Shah, vice president of pharmacy strategy at Walgreens.

Rite Aid adopted a prescription delivery program during the Covid-19 pandemic through a partnership with ScriptDrop. Service fees are currently waived for all eligible prescriptions, which excludes controlled substances and refrigerated medications but includes Paxlovid.

CVS also has one- or two-day delivery in most locations and on-demand delivery at some, which is provided free to people enrolled in the membership program.

In March, the Biden administration launched a federal Test-to-Treat initiative that streamlined access to Paxlovid for people who had Covid-19, with testing and prescribing all happening in one visit. In May, the program was broadened to specifically reach more vulnerable communities.

Khazanchi was author of a study published last month that found that Black and Hispanic people were more likely to live closer to Test-to-Treat sites than White people. But despite the physical proximity, these groups were less likely to get outpatient Covid-19 therapeutics – even though they’re at elevated risk of infection and severe disease.

Even if someone has a car or another way to get to the doctor’s office, pharmacy or other Test-to-Treat location, they’re often challenged by the time required to make that trip, said Dr. Rachel Werner, executive director of the University of Pennsylvania’s Leonard Davis Institute of Health Economics.

“It’s a combination of things that prevent access to care,” said Werner, whose research has focused on health equity. “Often, people have to take time off of work to do that, and they don’t always have paid sick leave. Everyone’s lives are complicated, and sometimes it’s hard to balance competing priorities.”

According to a report from health analytics company IQVIA, 9% of all new prescriptions in 2019 were “abandoned” at pharmacies, representing a gap in physician-recommended care that was not received by the patient. But home delivery programs that have expanded throughout the Covid-19 pandemic may help.

“I think it may be important to think about other medications or conditions where the time to treatment really matters. And those may be the ones that I think would be ripe for this kind of home-based delivery system,” Werner said. “These are urgent things that people might otherwise show up to an urgent clinic or ER for and instead could just get a medication.”

With the expansion of things like telehealth and options for home care, experts say, the Covid-19 pandemic helped widen the picture of what health care can look like.

“For far too long, we’ve been bound by the idea that health care is something that occurs within the four walls of a hospital or clinic,” Werner said. “What the Covid pandemic really did, which is important, is it made people realize that health care should be accessible where and when people need it, and it doesn’t have to be delivered in the physical structure of a health care setting.”

Experts say that while it’s critical to break down barriers in terms of access to medication, it’s important to also address the issue of trust.

In the research about accessibility to Test-to-Treat sites, Khazanchi and his co-authors suggested that programs should leverage trusted community stakeholders like local health-care providers for in-person outreach and other “low-tech, high-touch” methods to ensure equitable use.

Dr. Kedar Mate, president and CEO of the Institute for Healthcare Improvement and assistant professor at Weill Cornell Medical College, thinks about it in terms of supply and demand.

“Getting treatments to people who need them is principally an issue around access and ensuring that the supply goes to where the people are,” he said. “There’s a different problem, though, on the demand side. Are patients willing or interested to get tested and then get treated if they are found to be positive? That has everything to do with a totally different set of challenges which have to do with trust, information, disinformation, misinformation and belief in the health system overall.”

New boosters add limited protection against Covid-19 illness, first real-world study shows | CNN

 — 

Updated Covid-19 boosters that carry instructions to arm the body against currently circulating Omicron subvariants offer some protection against infections, according to the first study to look at how the boosters are performing in the real world. However, the protection is not as high as that provided by the original vaccine against earlier coronavirus variants, the researchers say.

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, called the new data “really quite good.”

“Please, for your own safety, for that of your family, get your updated Covid-19 shot as soon as you’re eligible to protect yourself, your family and your community,” Fauci said at a White House briefing Tuesday.

Uptake of the bivalent boosters, which protect against the BA.4/5 subvariants as well as the original virus strain, has been remarkably slow. Only 11% of eligible Americans have gotten them since they became available in early September.

The new study found that the updated boosters work about like the original boosters. They protect against symptomatic infection in the range of 40% to 60%, meaning that even when vaccine protection is its most potent, about a month after getting the shot, people may still be vulnerable to breakthrough infections.

That’s in about the same range as typical efficacy for flu vaccines. Over the past 10 years, CDC data shows, the effectiveness of the seasonal flu vaccines has ranged from a low of 19% to a high of around 52% against needing to see a doctor because of the flu. The effectiveness varies depending on how similar the strains in the vaccine are to the strains that end up making people sick.

The authors of the new study say people should realize that the Covid-19 vaccines are no longer more than 90% protective against symptomatic infections, as they were when they were first introduced in 2020.

“Unfortunately, the 90% to 100% protection was what we saw during like pre-Delta time. And so with Delta, we saw it drop into the 70% range, and then for Omicron, we saw it drop even lower, to the 50% range. And so I think what we’re seeing here is that the bivalent vaccine really brings you back to that sort of effectiveness that we would have seen immediately after past boosters, which is great. That’s where we want it to get,” said Dr. Ruth Link-Gelles, an epidemiologist at the US Centers for Disease Control and Prevention.

“This protection is not 100%, but it is something,” Link-Gelles said. “Especially going into the holidays where you’re likely to be traveling, spending time with elderly relatives, with vulnerable people. I think having some protection from infection and therefore some protection from infecting your loved one is better than having no protection at all.”

Link-Gelles says it also means that people should continue to adopt a layered approach to protection, utilizing rapid tests, good-quality masks and ventilation as a comprehensive approach, rather than relying on vaccines alone.

“This should be sort of one of the things in your toolbox for protecting yourself and your family,” she said. “Personally, we’re my family is all vaccinated up to date, but I think if we go to the airport tomorrow, we’ll be wearing our N95 [masks] because we’re seeing elderly relatives this weekend. And while we of course trust the vaccines, and I’m not super worried about a mild infection in myself or my healthy husband, we certainly would not want to infect his grandmother.”

Link-Gelles added that she expects that vaccine protection against severe outcomes from Covid-19, like hospitalization and death, will be higher, but that data isn’t in yet.

The study, which was led by CDC scientists, relied on health records from more than 360,000 tests given at nearly 10,000 retail pharmacies between Sept. 14 and Nov. 11, a period when the BA.4 and BA.5 subvariants were causing most Covid-19 infections in the US. The study included people ages 18 and up who had Covid-19 symptoms and were not immunocompromised.

The study looked at how effective the boosters were in two ways: Researchers calculated a value called absolute vaccine effectiveness, which compared the odds of symptomatic infection in people who received bivalent boosters with those who reported being unvaccinated. They also calculated relative vaccine effectiveness, which looked at the odds of symptomatic infection in people who received updated bivalent boosters compared with those who had two, three or four doses of the original single-strain vaccine.

Compared with people who were unvaccinated, adults 18 to 49 who had gotten bivalent boosters were 43% less likely to get sick with a Covid-19 infection. Older adults, who tend to have weaker immune function, got less protection. Those ages 50 to 64 were 28% less likely, and those ages 65 and up were 22% less likely to get sick with Covid-19 than the unvaccinated group.

The relative vaccine effectiveness showed the added protection people might expect on top of whatever protection they had left after previous vaccine doses. If a person was two to three months past their last vaccine dose, the bivalent boosters added an average of 30% protection for those who were ages 18 to 49, 31% more protection if they were 50 to 64, and 28% more protection if they were 65 or older. At 3 months after their last booster, people ages 50 and older still had about 20% protection from Covid-19 illness, CDC data show. So overall, the updated boosters got them to around 50% effectiveness against symptomatic infection.

If a person was more than eight months away from their last vaccine dose, they got more protection from the boosters. But Link-Gelles said that by eight months, there was little protection left from previous shots against Omicron and its variants, meaning the vaccine effectiveness for this group was probably close to their overall protection against infection.

Those ages 18 to 49 who were eight months or more past their last dose of a vaccine had 56% added protection against a Covid-19 infection with symptoms; adults 50 to 64 had 48% added protection, and adults over 65 had 43% added protection, on top of whatever was left from previous vaccinations.

John Moore, an immunologist and microbiologist at Weill Cornell Medicine, said it boils down to the fact that that boosters will probably cut your risk of getting sick by about 50%, and that protection probably won’t last.

“Having a booster will give you some additional protection against infection for a short term, which is always what we see with a booster, but it won’t last long. It’ll decline, and it will decline more as the more resistant variants spread,” said Moore, who was not involved in the new research.

The immunity landscape in the United States is more complex than ever. According to CDC data, roughly two-thirds of Americans have completed at least their primary series of Covid-19 vaccines. And data from blood tests shows that almost all Americans have some immunity against the virus, thanks to infection, vaccination or both.

A new preprint study from researchers at Harvard and Yale estimates that 94% of Americans have been infected with the virus that causes Covid-19 at least once, and 97% have been infected or vaccinated, increasing protection against a new Omicron infection from an estimated 22% in December 2021 to 63% by November 10, 2022. Population protection against severe disease rose from an estimated 61% in December 2021 to around 89%, on average, this November.

All of this means the US is in a better spot, defensively at least, than it ever has been against the virus – which is not to say that the country couldn’t see another Covid-19 wave, especially if a new variant emerges that is very different from what we’ve seen, if immunity continues to wane or if behavior shifts dramatically.

Is It Flu, RSV or COVID? Experts Fear the ‘Tripledemic’

Post By Health , , , , , ,


Oct. 25, 2022 – Just when we thought this holiday season, finally, would be the back-to-normal one, some infectious disease experts are warning that a so-called tripledemic – influenza, COVID-19, and RSV – may be in the forecast.

The warning isn’t without basis. 

  • The flu season has gotten an early start. As of Oct. 21, early increases in seasonal flu activity have been reported in most of the country, the CDC says, with the southeast and south-central areas having the highest activity levels. 
  • Children’s hospitals and emergency departments are seeing a surge in children with RSV.
  • COVID-19 cases are trending down, according to the CDC, but epidemiologists – scientists who study disease outbreaks – always have their eyes on emerging variants. 

Predicting exactly when cases will peak is difficult, says Justin Lessler, PhD, a professor of epidemiology at the University of North Carolina at Chapel Hill. Lessler is on the coordinating team for the COVID-19 Scenario Modeling Hub, which aims to predict the course COVID-19, and the Flu Scenario Modeling Hub, which does the same for influenza.

For COVID-19, some models are predicting some spikes before Christmas, he says, and others see a new wave in 2023. For the flu, the model is predicting an earlier-than-usual start, as the CDC has reported.  

While flu activity is relatively low, the CDC says, the season is off to an early start. For the week ending Oct. 21, 1,674 patients were hospitalized for flu, higher than in the summer months but fewer than the 2,675 hospitalizations for the week of May 15, 2022. 

As of Oct. 20, COVID-19 cases have declined 12% over the last 2 weeks, nationwide. But hospitalizations are up 10% in much of the Northeast, The New York Times reports, and the improvement in cases and deaths has been slowing down. 

As of Oct. 15, 15% of RSV tests reported nationwide were positive, compared with about 11% at that time in 2021, the CDC says. The surveillance collects information from 75 counties in 12 states. 

Experts point out that the viruses — all three are respiratory viruses —  are simply playing catchup. 

“They spread the same way and along with lots of other viruses, and you tend to see an increase in them during the cold months,” says Timothy Brewer, MD, professor of medicine and epidemiology at UCLA.

The increase in all three viruses “is almost predictable at this point in the pandemic,” says Dean Blumberg, MD, a professor and chief of pediatric infectious diseases at the University of California Davis Health. “All the respiratory viruses are out of whack.” 

Last year, RSV cases were up, too, and began to appear very early, he says, in the summer instead of in the cooler months. Flu also appeared early in 2021, as it has this year. 

That contrasts with the flu season of 2020-2021, when COVID precautions were nearly universal, and cases were down. At UC Davis, “we didn’t have one pediatric admission due to influenza in the 2020-2021 [flu] season,” Blumberg says. 

The number of pediatric flu deaths usually range from 37 to 199 per year, according to CDC records. But in the 2020-2021 season, the CDC recorded one pediatric flu death in the U.S.

Both children and adults have had less contact with others the past 2 seasons, Blumberg says, “and they don’t get the immunity they got with those infections [previously]. That’s why we are seeing out-of-season, early season [viruses].” 

Eventually, he says, the cases of flu and RSV will return to previous levels. “It could be as soon as next year,” Blumberg says. And COVID-19, hopefully, will become like influenza, he says.

“RSV has always come around in the fall and winter,” says Elizabeth Murray, DO, a pediatric emergency medicine doctor at the University of Rochester Medical Center and a spokesperson for the American Academy of Pediatrics. This year, children are back in school and for the most part not masking, she says. “It’s a perfect storm for all the germs to spread now. They’ve just been waiting for their opportunity to come back.” 

Self-Care vs. Not

RSV can pose a risk for anyone, but most at risk are children under age 5, especially infants under age 1, and adults over age 65.  There is no vaccine for it. Symptoms include a runny nose, decreased appetite, coughing, sneezing, fever, and wheezing. But in young infants, there may only be decreased activity, crankiness, and breathing issues, the CDC says.

Keep an eye on the breathing if RSV is suspected, Murray tells parents. If your child can’t breathe easily, is unable to lie down comfortably, can’t speak clearly, or is sucking in the chest muscles to breathe, get medical help. Most kids with RSV can stay home and recover, she says, but often will need to be checked by a medical professional.

She advises against getting an oximeter to measure oxygen levels for home use. “They are often not accurate,” she says. If in doubt about how serious your child’s symptoms are, “don’t wait it out,” she says, and don’t hesitate to call 911.

Symptoms of flu, COVID, and RSV can overlap.  But each can involve breathing problems, which can be an emergency. 

“It’s important to seek medical attention for any concerning symptoms, but especially severe shortness of breath or difficulty breathing, as these could signal the need for supplemental oxygen or other emergency interventions,” says Mandy De Vries, a respiratory therapist and director of education at the American Association for Respiratory Care. Inhalation treatment or mechanical ventilation may be needed for severe respiratory issues.

Precautions

To avoid the tripledemic – or any single infection – Timothy Brewer, MD, a professor of medicine and epidemiology at UCLA, suggests some familiar measures: “Stay home if you’re feeling sick. Make sure you are up to date on your vaccinations. Wear a mask indoors.”
