For nearly a month, the Centers for Disease Control and Prevention’s online vaccine tracker has shown that virtually everyone 65 and older in the United States — 99.9% — has received at least one covid vaccine dose.
That would be remarkable — if true.
But health experts and state officials say it’s certainly not.
They note that the CDC as of Dec. 5 has recorded more seniors at least partly vaccinated — 55.4 million — than there are people in that age group — 54.1 million, according to the latest census data from 2019. The CDC’s vaccination rate for residents 65 and older is also significantly higher than the 89% vaccination rate found in a poll conducted in November by KFF.
Similarly, a YouGov poll, conducted last month for The Economist, found 83% of people 65 and up said they had received at least an initial dose of vaccine.
And the CDC counts 21 states as having almost all their senior residents at least partly vaccinated (99.9%). But several of those states show much lower figures in their vaccine databases, including California, with 86% inoculated, and West Virginia, with nearly 90% as of Dec. 6.
The questionable CDC data on seniors’ vaccination rates illustrates one of the potential problems health experts have flagged about CDC’s covid vaccination data.
Knowing with accuracy what proportion of the population has rolled up sleeves for a covid shot is vital to public health efforts, said Dr. Howard Forman, a professor of public health at Yale University School of Medicine.
“These numbers matter,” he said, particularly amid efforts to increase the rates of booster doses administered. As of Dec. 5, about 47% of people 65 and older had received a booster shot since the federal government made them available in September.
“I’m not sure how reliable the CDC numbers are,” he said, pointing to the discrepancy between state data and the agency’s 99.9% figure for seniors, which he said can’t be correct.
“You want to know the best data to plan and prepare and know where to put resources in place — particularly in places that are grossly undervaccinated,” Forman said.
Getting an accurate figure on the proportion of residents vaccinated is difficult for several reasons. The CDC and states may be using different population estimates. State data may not account for residents who get vaccinated in a state other than where they live or in clinics located in federal facilities, such as prisons, or those managed by the Veterans Health Administration or Indian Health Service.
CDC officials said the agency may not be able to determine whether a person is receiving a first, second or booster dose if their shots were received in different states or even from providers within the same city or state. This can cause the CDC to overestimate first doses and underestimate booster doses, CDC spokesperson Scott Pauley said.
“There are challenges in linking doses when someone is vaccinated in different jurisdictions or at different providers because of the need to remove personally identifiable information (de-identify) data to protect people’s privacy,” according to a footnote on the CDC’s covid vaccine data tracker webpage. “This means that, even with the high-quality data CDC receives from jurisdictions and federal entities, there are limits to how CDC can analyze those data.”
On its dashboard, the CDC has capped the percentage of the population that has received vaccine at 99.9%. But Pauley said its figures could be off for multiple reasons, such as the census denominator not including everyone who currently resides in a particular county, like part-time residents, or potential data-reporting errors.
Liz Hamel, vice president and director of public opinion and survey research at KFF, agrees it’s highly unlikely 99.9% of seniors have been vaccinated. She said the differences between CDC vaccination rates and those found in KFF and other polls are significant. “The truth may be somewhere in between,” she said.
Hamel noted the KFF vaccination rates tracked closely with CDC’s figures in the spring and summer but began diverging in fall, just as booster shots became available.
KFF surveys show the percentage of adults at least partly vaccinated changed little from September to November, moving from 72% to 73%. But CDC data shows an increase from 75% in September to 81% in mid-November.
As of Dec. 5, the CDC says, 83.4% of adults were at least partly vaccinated.
William Hanage, an associate professor of epidemiology at Harvard University, said such discrepancies call into question that CDC figure. He said getting an accurate figure on the percentage of seniors vaccinated is important because that age group is most vulnerable to severe consequences of covid, including death.
“It is important to get them right because of the much-talked-about shift from worrying about cases to worrying about severe outcomes like hospitalizations,” Hanage said. “The consequences of cases will increasingly be determined by the proportion of unvaccinated and unboosted, so having a good handle on this is vital for understanding the pandemic.”
For example, CDC data shows New Hampshire leads the country in vaccination rates with about 88% of its total population at least partly vaccinated.
The New Hampshire vaccine dashboard shows 61.1% of residents are at least partly vaccinated, but the state is not counting all people who get their shots in pharmacies due to data collection issues, said Jake Leon, spokesperson for the state Department of Health and Human Services.
In addition, Pennsylvania health officials say they have been working with the CDC to correct vaccination rate figures on the federal website. The state is trying to remove duplicate vaccination records to make sure the dose classification is correct — from initial doses through boosters, said Mark O’Neil, spokesperson for the state health department.
As part of the effort, in late November the CDC reduced the percentage of adults in the state who had at least one dose from 98.9% to 94.6%. It also lowered the percentage of seniors who are fully vaccinated from 92.5% to 84%.
However, the CDC has not changed its figure on the proportion of seniors who are partly vaccinated. It remains 99.9%. The CDC dashboard says that 3.1 million seniors in Pennsylvania were at least partly vaccinated as of Dec. 5. The latest census data shows Pennsylvania has 2.4 million people 65 and older.

Unraveling How Strigoractone Hormone Regulates Massive Gene Networks Controlling Plant Growth
As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond to the environment and integrate the signals from outside with endogenous developmental programs.
New research from Nitzan Shabek’s laboratory at the UC Davis College of Biological Sciences, published in Nature Plants, unravels the underlying mechanism of protein targeting and destruction in a specific plant hormone signaling pathway.
Our lab aims at deciphering sensing mechanisms in plants and understanding how specific enzymes function can be regulated at the molecular levels. We have been studying a new plant hormone signal, strigolactone, that governs numerous processes of growth and development including branching and root architecture.”
Nitzan Shabek, assistant professor of biochemistry and structural biology, Department of Plant Biology
The work stems from a study by Shabek, published in Nature in 2018, unravelling molecular and structural changes in an enzyme, MAX2 (or D3) ubiquitin ligase. MAX2 was found in locked or unlocked forms that can recruit a strigolactone sensor, D14, and target for destruction a DNA transcriptional repressor complex, D53. Ubiquitins are small proteins, found in all eukaryotes, that “tag” other proteins for destruction within a cell.
To find the key to unlock MAX2 and to better understand its molecular dynamics in plants, postdoctoral fellows Lior Tal and Malathy Palayam, with junior specialist Aleczander Young, used an approach that integrated advanced structural biology, biochemistry, and plant genetics.
“We leveraged structure-guided approaches to systemically mutate MAX2 enzyme in Arabidopsis and created a MAX2 stuck in an unlocked form”, said Shabek, “some of these mutations were made by guiding CRISPR/Cas9 genome editing thus providing us a discovery platform to study and analyze the different signaling outputs and illuminate the role of MAX2 dynamics.”
They found that in the unlocked conformation, MAX2 can target the repressor proteins and biochemically decorate them with small ubiquitin proteins, tagging them for destruction. Removing these repressors allows other genes to be expressed – activating a massive gene network that governs shoot branching, root architecture, leaf senescence, and symbiosis with fungi, Shabek said.
Sending these repressors to the proteasome disposal complexes requires the enzyme to relock again. The team also showed that MAX2 not only target the repressors proteins, but once it is locked the strigolactone sensor itself gets destroyed, returning the system to its original state.
Finally, the study uncovered the key to the lock, an organic acid metabolite that can directly trigger the conformational switch.
“Beyond the implication in plants signaling, this is the first work that placed a primary metabolite as a direct new regulator of this type of ubiquitin ligase enzymes and will open new avenues of study in this direction,” Shabek said.
Additional coauthors on the paper are specialist Mily Ron and Professor Anne Britt, Department of Plant Biology. The study was supported by NSF CAREER and EAGER grants to Shabek. X-ray crystallography data was obtained at the Advanced Light Source, Lawrence Berkeley National Laboratory, a U.S. Department of Energy user facility.

UrFU Sociologists Identify Digital Fears Among Young People
Sociologists at the Ural Federal University (UrFU) have identified digital fears among young people. According to experts, these are additional fears that do not replace, but complement and reinforce traditional ones. They emerged against the background of uncertainty, the growth of forces beyond human control. Developed emotional intelligence, creativity, and the ability to collaborate help to overcome them.
In the study, sociologists interviewed 1,050 people aged 18-30. Respondents were asked to assess which digital risks concern them most. The study was launched in 2020 and the results were published in April 2022 in the Changing Societies & Personalities journal.
The first group of fears is influence and control. It touches on the problem of interference with privacy by technical means. This category is the most significant for young people: 55.8% are afraid of total control by means of video-surveillance and monitoring software on their mobile devices. 48.5% of respondents believe they are at risk of wiretapping, tracking content in social networks, and inability to keep correspondence secret.”
Natalia Antonova, Professor, Department of Applied Sociology, UrFU
45.8% of young people fear the manipulative influence of the media and an increase in fake news. At the same time, only 27.8% and 18.1% of respondents are concerned about microchipping and genetic manipulation, respectively. It is likely that these threats seem more controllable, both from the individual (through control of food choices, medical procedures, etc.) and from government programs, the researchers believe.
The second group of concerns is crime and security. Here young people are wary of illegal actions using digital technology.
“One of the main fears of 56% of young people is the security of personal data. This is related both to the growth of personal information in social networks and messengers, and to the growth of hacker attacks and viruses. 42.9% of young citizens are afraid of Internet fraudsters, and 25.8% are afraid of losing important information, including smashing their phones, not saving data, forgetting their passwords, or being without an Internet connection,” explains Sofia Abramova, Associate Professor at the Department of Applied Sociology at UrFU.
The third group of fears is based on changes in the way and pace of life, ways of interaction. Thus, 28.4% of respondents indicate a constant lack of time, the acceleration of communications, and worries about not being able to complete all tasks in time. Respondents are also concerned about the growth of online communications and communications with electronic systems (bots, autoresponders, product systems, etc.).
“As a result, 15.3% of young people raise problems related to increasing social distrust against the background of increasing dependence of human life and health on other people and electronic systems: in public transport, planes, elevators, medical intervention,” explains Sofia Abramova.
Respondents also fear the negative consequences of technological development. For example, 22.2% of young citizens fear the robotization of labor processes and the displacement of humans by robots. 14.6% speak directly about negative emotions in relation to the expansion of artificial intelligence.
The fifth type of fear is social inequality. Young people negatively assess the growth of inequality in access to information resources and technology, the exclusion of citizens from the economy depending on the level of digital competence and education, and age. As a result, they fear that benefits will be distributed more and more unequally, both among the inhabitants of the country and between countries.
“It is noteworthy that young people are simultaneously afraid of total surveillance via phone and afraid of being left without mobile devices. Fears shape the irrational behavior of the digital generation, entailing serious transformations in everyday life,” says Natalia Antonova.

Study demonstrates increased incidence of SARS-CoV-2 Omicron breakthrough infection in cancer patients
In a recently published article in the journal Cancer Cell, scientists have demonstrated the incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in cancer patients residing in Austria and Italy. The study reveals an induction in Omicron breakthrough infections in patients with hematologic and solid cancers.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of the coronavirus disease 2019 (COVID-19) pandemic, has been found to cause severe infections in immunocompromised patients, including cancer patients. Moreover, a relatively lower level of neutralizing antibodies in response to COVID-19 vaccines has also been observed in cancer patients, especially those receiving B cell-targeting therapies.
The emergence of SARS-CoV-2 variants with improved immune fitness, such as delta and Omicron variants, has caused a sharp increase in breakthrough infections even in fully vaccinated individuals. However, the vaccines still show high protective efficacy against severe and fatal infections. COVID-19 vaccines have shown acceptable efficacy against severe disease, even in Omicron-infected cancer patients. However, the isolation and quarantine measures associated with SARS-CoV-2 infection may impair the routine administration of anticancer therapy, which can reduce the survival prognosis in cancer patients.
In the current study, the scientists have assessed the incidence of SARS-CoV-2 infection in cancer patients throughout the pandemic.
The study included 3,959 cancer patients, of whom 77% had solid cancer, and 23% had hematologic cancer. About 69% of the patients did not receive any anticancer treatment at the time of COVID-19 vaccination. Regarding vaccine coverage, about 85% of the patients had received at least one vaccine dose, and 15% remained unvaccinated. The incidence of SARS-CoV-2 infection in these patients was assessed between February 2020 and 2022.
SARS-CoV-2 infection was detected in about 24% of the patients during the study period. During the delta-dominated wave, vaccine breakthrough infection was observed in 43% of the patients. In contrast, a significantly higher percentage of breakthrough infection (70%) was observed among the patients during the Omicron-dominated wave. During both delta and Omicron waves, cancer patients receiving systemic anticancer treatment showed a significantly higher percentage of breakthrough infection than those not receiving treatment (83% vs. 56%).
Regarding disease severity irrespective of vaccination status, a higher frequency of COVID-19-related hospitalization was observed during the delta wave compared to that during the Omicron wave. However, a relatively shorter duration of hospital stay was observed in vaccinated patients compared to that in unvaccinated patients. In addition, only 9% of patients with breakthrough infections were admitted to the intensive care unit (ICU). This highlights the protective efficacy of COVID-19 vaccines against severe disease.
Humoral immune response to vaccination
To determine vaccine-induced antibody response against delta and Omicron variants, the scientists measured blood levels of anti-delta and anti-Omicron spike receptor-binding domain (RBD) antibodies in a total of 78 cancer patients. In the analysis, they also included 25 healthcare workers as controls.
In response to vaccination, healthcare workers showed higher levels of total anti-spike antibodies compared to cancer patients. The lowest level of wildtype RBD-specific antibodies was observed in hematologic cancer patients receiving B cell-targeted treatment, followed by hematologic cancer patients not receiving B cell-targeted treatment and patients with solid tumors. A similar trend was observed for delta- and Omicron-specific spike RBD antibodies.
The serum samples collected from hematologic cancer patients without B cell-targeted treatment and solid tumor patients significantly inhibited the interaction between wildtype/delta RBD and angiotensin-converting enzyme 2 (ACE2; host cell receptor for viral entry). However, a significantly lower level of inhibition was observed for patients receiving B cell-targeted treatment. Importantly, a marked reduction in inhibition of Omicron RBD – ACE2 interaction was observed for all patients with solid tumors and hematologic cancer.
The study demonstrates an increased incidence of vaccine breakthrough infections but a reduced disease severity among patients with solid tumors and hematologic cancer during the Omicron wave compared to the delta wave.
The study also highlights that COVID-19 vaccine-induced antibody response is lower in cancer patients than in healthy individuals. The reduction in antibody response is highest among hematologic patients receiving B cell-targeted treatment. Overall, a significant impairment in vaccine-induced Omicron neutralization has been observed in cancer patients.
