Covid is on the rise again in the US, as children begin returning to school and as officials plan to restrict booster shots.<\/p>\n
While cases are increasing less quickly than at the start of other surges, it is too soon to tell how big the current late-summer wave could get \u2013 and with highly varied immune responses from prior infections and vaccinations, it is difficult to know how severe illness could be, experts said.<\/p>\n
The risks of a wave are compounded by new vaccine restrictions from the Trump administration.<\/p>\n
\u201cIf you\u2019re vaccinated against Covid-19, you\u2019re less likely to get infected,\u201d said Andrew Pekosz, a virologist at Johns Hopkins University. \u201cBut we haven\u2019t gotten a lot of people vaccinated for the past few years, and with the current recommendations changing, it\u2019s even less likely.\u201d<\/p>\n
Future waves could become more severe as vaccination lags and immunity drops, Pekosz said.<\/p>\n
Several key measurements \u2013 including wastewater data, test positivity and emergency room visits \u2013 indicate a new rise in infections.<\/p>\n
In the past, Covid has surged about twice a year, usually in the summer and the winter. But the pattern can change, as it does with other respiratory viruses \u2013 with late or early starts to the season and curveballs like double peaks.<\/p>\n
\u201cEach year has been different, so in some ways, this is more of the same,\u201d said Sam Scarpino, a professor of health sciences at Northeastern University.<\/p>\n
Cases are increasing or probably increasing in 26 US states, especially in the south and midwest, according to the US Centers for Disease Control and Prevention (CDC).<\/p>\n
\u201cIn the snapshot that we\u2019re seeing right now, increases are happening at a relatively low rate, and that would indicate that we probably aren\u2019t going to peak at a very high level. But again, this is early in this summer surge, so we really have to keep monitoring the data and paying attention to what it\u2019s telling us,\u201d Pekosz said.<\/p>\n
The variants currently spreading around the globe have known immune-evasion properties, Scarpino said.<\/p>\n
\u201cYou can look at the rise that we\u2019re seeing, the fact that we know it\u2019s an immune-escape variant, and I think we can be pretty confident that there\u2019s some kind of wave coming,\u201d Scarpino said. \u201cWhether it\u2019s going to be large or small, I don\u2019t think we could really say one way or the other.\u201d<\/p>\n
But \u201cthe vaccines are still providing some protection,\u201d he said. \u201cIt\u2019s never too late to get the booster.\u201d<\/p>\n
Yet officials softened the recommendation for children on Covid vaccines, and they removed the suggestion entirely for pregnant people, despite the clear benefits of the shot in reducing the risk of severe illness and death during pregnancy.<\/p>\n
A new, more effective Covid shot from Moderna and the Covid shot from Novavax were approved only for people over 65 or people over the age of 12 with health conditions.<\/p>\n
The independent advisers to the US Food and Drug Administration (FDA) recommended that vaccine manufacturers once again update booster shots this fall to a more recent variant.<\/p>\n
Covid boosters are usually recommended for all adults.<\/p>\n
But this fall, the boosters may be limited to older people and those with health conditions, FDA officials wrote in May.<\/p>\n
\u201cSo it\u2019s a big question mark, going into the fall, is who it\u2019s going to be approved for,\u201d Scarpino said. \u201cIf it\u2019s not approved, can you still pay out of pocket for it? How much is it going to cost? And then are there going to be supply chain issues?\u201d<\/p>\n
Health officials have also called for placebo trials for the boosters to judge their benefit to people without pre-existing conditions \u2013 but such trials would be unethical and extremely difficult to conduct, experts say.<\/p>\n
\u201cClearly, the guidelines right now are focused on the populations that are more prone to have severe disease and severe outcomes. It\u2019s always been good to vaccinate that population,\u201d Pekosz said.<\/p>\n
But the Trump administration is moving away from the approach of immunizing broad swaths of the population \u2013 especially those most likely to get and pass the virus on, like children, he said.<\/p>\n
\u201cIf you vaccinate broadly, you can reduce the spread of Covid-19 in the population,\u201d Pekosz said. \u201cThe benefit, to me, is very clearly on the side of getting vaccinated.\u201d<\/p>\n
Some of the pre-existing conditions proposed by FDA officials include asthma, diabetes, depression and physical inactivity.<\/p>\n
According to that list, \u201cbasically everybody\u2019s eligible for one of the vaccines,\u201d Scarpino said. And doctors, including pediatricians, may also prescribe vaccines for off-label use.<\/p>\n
Yet the more restrictions are placed on vaccination, the harder it is to reach even the people who need it most, Pekosz noted.<\/p>\n
Antivirals like Paxlovid could also see wider use, the experts said.<\/p>\n
\u201cWe shouldn\u2019t forget about the antivirals,\u201d Pekosz said. \u201cThose don\u2019t seem to be the target of more restrictive use by the CDC or the FDA, so those will be available for people if they do get infected.\u201d<\/p>\n
A program to make Paxlovid more affordable to those who need it is slated to end in December.<\/p>\n
\u201cThe benefits of antiviral treatment are very clear with respect to hospitalization and mortality decreases,\u201d Pekosz said.<\/p>\n
Paxlovid is still highly effective against current variants, Scarpino said. \u201cThere\u2019s a whole bunch of good reasons to get it.\u201d<\/p>\n
Rates of hospitalizations and deaths in recent waves have dropped among adults compared with earlier Covid waves, but the virus remains deadly. An estimated 35,000 to 54,000 people in the US have died of Covid since October.<\/p>\n
Children continue to see hospitalizations rates from Covid similar to previous years.<\/p>\n
Covid cases can be less severe because of immunity \u2013 from prior infection or from vaccination.<\/p>\n
\u201cIt\u2019s not so much that the virus has become less dangerous, it\u2019s that we have immunity, so we fight off the virus more efficiently than we did early in the pandemic,\u201d Pekosz said.<\/p>\n
That\u2019s why vaccinations remain a key part of controlling Covid, he said. Without boosters, people become more susceptible to severe illness and death.<\/p>\n
About 23% of adults had received updated Covid boosters as of April.<\/p>\n
About 5.6% of children aged six months to four years are vaccinated against Covid, and about 15% of children aged five to 17 are vaccinated, according to the CDC.<\/p>\n
\u201cChildren\u2019s cases are always surging, because children don\u2019t have much immunity to Covid,\u201d Pekosz said. \u201cCovid cases are really occurring in children at a very high level right now. It\u2019s not nearly as dangerous in children as it is in adults, but it still causes a lot of hospitalizations in children.\u201d<\/p>\n
Hospitalizations and deaths are not the only ways to measure the damage and disruption wrought by Covid.<\/p>\n
While the Trump administration has not released updated data on long Covid, an estimated 5.3% of all adults in the US said they were currently experiencing long-term Covid symptoms as of September.<\/p>\n
Even in times of lower transmission, Covid still circulates, with 149 deaths in the week ending 28 June, the last week for which the CDC shares full mortality data.<\/p>\n
\u201cIt\u2019s still a little surprising that it\u2019s around all year,\u201d said Pekosz. During lull times, \u201cwe\u2019re not seeing it disappear completely, like we do with other respiratory viruses.\u201d<\/p>\n
When it comes to keeping rates of Covid low, \u201cit\u2019s all the same stuff we usually go over,\u201d Pekosz said \u2013 getting vaccinated, taking precautions like masking and using air purifiers, and staying home if you\u2019re sick.<\/p>\n
\u201cBut it\u2019s just a very different environment these days. When the government doesn\u2019t use the science to drive their decision making, you can see the confusion that it puts into the general public.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
