04/21/2021 09:06 GMT — B.1.1.7 variant 45% more contagious than original virus

A recent study, which appears in the journal Cell Reports Medicine, analyzed data from 300,000 polymerase chain reaction, or PCR, tests taken throughout Israel. The scientists conclude that the B.1.1.7 variant, which was first identified in the United Kingdom, is 45% more contagious than the original virus.

The scientists were able to chart the rapid spread of the new variant. They found that on December 24, 2020, only 5% of cases were attributable to the B.1.1.7 variant. By January 2021, the variant was responsible for 90% of cases. Today, that figure is around 99.5%.

Speaking about the results of the study, one of the authors, Prof. Ariel Munitz, says: “To explain this dramatic increase, we compared the R number of the SARS-CoV-2 virus with the R of the [B.1.1.7] variant. In other words, we posed the question: How many people, on the average, contract the disease from every person who has either variant? We found that the British variant is 45% — almost 1.5 times — more contagious.”

04/16/2021 12:18 GMT — SARS-CoV-2 variant first identified in India now detected in UK

According to an update, Public Health England (PHE) has detected cases of the B.1.617 variant in the United Kingdom for the first time. Health experts first identified this variant in India. Currently, PHE classes it as a “variant under investigation.” In total, the organization detected 77 cases.

B.1.617 has two mutations in the spike protein. Scientists believe this might make it more transmissible and better able to avoid the body’s immune response.

According to Prof. Paul Hunter, a professor in medicine at the University of East Anglia in the U.K., “These two escape mutations working together could be a lot more problematic than the South African and Brazilian variants, [which] have only got one escape mutation. It might be even less controlled by vaccines than the Brazilian and South African variants.”

However, at this stage, there is very little data on this variant. As Prof. Christina Pagel, director of the Clinical Operational Research Unit at University College London in the U.K., explains, “We do not know yet whether it can escape existing vaccines, but it has several concerning mutations.”

04/16/2021 09:04 GMT — People may need third vaccine dose within 12 months

According to Pfizer CEO Albert Bourla, people are likely to need a third dose of COVID-19 vaccine within 12 months of their second dose. Although more data need to become available to confirm this, he believes that yearly COVID-19 vaccinations might be necessary.

04/13/2021 15:28 GMT — CDC and FDA halt administration of Johnson & Johnson COVID-19 vaccine in the US

In a statement released to the press today — April 13, 2021 — a spokesperson for the Centers for Disease Control and Prevention (CDC) and another for the Food and Drug Administration (FDA) announced that the two federal agencies now recommend halting the administration of the Johnson & Johnson (Janssen) COVID-19 vaccine.

The spokespeople cited reports of six blood clotting cases that followed the administration of this vaccine, all of which occurred in adult women. They said that the CDC and FDA cannot support the vaccine’s continued rollout until a more in-depth investigation takes place.

Dr. Peter English, a retired consultant in communicable disease control, has commented on this decision, calling it “a highly precautionary move.”

“The alert related to the AstraZeneca vaccine, where a similar association is considered possible, will have raised awareness of a possible association with other vaccines,” Dr. English said.

“Nevertheless,” he added, “the fact that such a small possible risk has been identified is very reassuring — it shows that pharmacovigilance systems are working.”

04/13/2021 14:47 GMT — Oxford-AstraZeneca vaccine side effects: Video update

04/13/2021 09:47 GMT — Asthma drug may speed up recovery

According to the preliminary results of a study, the asthma drug budesonide may speed up recovery from COVID-19. The researchers found that early treatment with the drug shortened recovery time by a median of 3 days. Budesonide is a corticosteroid that is widely available and inexpensive.

The interim analysis included data from 1,779 people with a SARS-CoV-2 infection and “risk factors for adverse outcomes.” The researchers provided 751 of the participants with a budesonide inhaler and standard care, while the remaining 1,028 received only standard care.

Although the results are encouraging, it is important to note that this paper is a preprint, so it has not yet been peer reviewed.

04/09/2021 15:35 GMTThe United Kingdom may have achieved herd immunity, projections from University College London claim

Researchers from University College London (UCL) have recently updated their long-term forecast of the progression of the COVID-19 epidemic in the United Kingdom.

In their latest release, UCL scientists say that their modeling study indicates that a “herd immunity threshold (of 73.4%) will be reached” on April 9, meaning that on this day, an estimated 73.4% of the U.K. population will have become immune to SARS-CoV-2 — by either having overcome infection with this virus or having received a full COVID-19 vaccine.

This contradicts previous UCL estimates, which indicated that herd immunity would be reached in the U.K. by mid-May.

Other researchers — unaffiliated with the study at UCL — have expressed doubts about the accuracy of these predictions.

For example, Prof. Paul Hunter — who is a professor in medicine at The Norwich School of Medicine at the University of East Anglia — has said that he is “quite skeptical of the conclusions reported by the Dynamic Causal Modelling group at UCL.”

“For any infection, herd immunity can only be said to have been achieved if a sufficient proportion of the population has acquired immunity either from immunization or natural infection to bring the R value below 1 [so] that the disease [will] ultimately disappear. But for herd immunity to really happen, that immunity has to last. At present, we do not know how long the immunity generated by immunization will last nor what impact the emergence and spread of new variants will have on vaccine effectiveness,” he noted.

Dr. Louise Dyson, an associate professor in epidemiology at the University of Warwick, has further commented that the UCL research “does not appear to be internally consistent.” She has observed that the UCL group’s definition of the “herd immunity threshold” and its understanding of “the history of the epidemic” in the U.K. have shifted with each monthly update.

“It would seem unwise to base any policy decisions on estimates that change so much in their understanding of the history of the epidemic, without investigating the reasons for such changes,” Dr. Dyson warned.

04/08/2021 13:45 GMT — First ever images show how cells respond to COVID-19 vaccine

For the first time, researchers have been able to obtain images of the spike proteins that develop on the surfaces of cells that have been exposed to the Oxford-AstraZeneca vaccine and compare them with the “original,” or “native,” spike proteins that characterize the new coronavirus.

Co-lead study author Max Crispin, who is a professor of glycobiology at the University of Southampton in the United Kingdom, said: “In this study we set out to see how closely the vaccine induced spikes resembled those of the infectious virus. We were really pleased to see a large amount of native-like spikes.”

“This study will hopefully provide further understanding for the public, helping them see how the Oxford-AstraZeneca vaccine works,” Prof. Crispin added.

“Many people may not realize how their cells become little factories manufacturing viral spikes that then trigger the immune response needed to fight off the disease. This may also provide reassurance that the vaccine is doing its job and generating the material that we need to present to our immune systems.”

04/08/2021 13:40 GMT — Brazil registers over 4,000 deaths in 24 hours for the first time

Brazil has registered over 4,000 deaths in 24 hours for the first time largely as a result of the new SARS-CoV-2 variant, called the P.1 variant. This is more contagious than other variants.

The surge in cases has brought Brazil to a total death toll of 337,000. Overall, Brazil has recorded over 13 million cases of COVID-19. Globally, the country is second only to the United States in terms of both deaths and total case numbers.

04/07/2021 16:40 GMT — EMA: ‘Possible link’ between AstraZeneca and ‘very rare’ blood clot incidents, but benefits still outweigh risks overall

Today, the European Medicines Agency (EMA) held a press briefing on AstraZeneca’s COVID-19 vaccine. 

The EMA concluded that “unusual blood clots with low blood platelets should be listed as very rare side effects” of the AstraZeneca vaccine. 

However, the risk factors for this possibility remain unknown for now, and the EMA has concluded that “the overall benefits of the vaccine in preventing COVID-19 outweigh the risks of side effects.”

04/07/2021 16:40 GMT — UK regulatory body issues new guidance for AstraZeneca vaccine

The Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom has held a press conference today to discuss the AstraZeneca vaccine.
In it, Dr. June Raine, chief executive of the MHRA, said the benefits of the AstraZeneca vaccine continue to outweigh the risks for “the vast majority of people.”

However, the risk-benefit analysis could be more finely balanced for young people, the experts said, as the risk of rare blood clotting incidents is higher in this age group than it is in older adults. The reasons for this increased risk, however, remain unclear.

Therefore, the MHRA recommends that people under the age of 30 who do not have a preexisting condition that may put them at a higher risk of COVID-19 should be given an alternative to the AstraZeneca shot.

Sir Munir Pirmohamed, chair of the Commission on Human Medicines, also explained that pregnant women should discuss the risks with their doctor before taking the vaccine. People who have had blood disorders in the past should only take the vaccine if they have decided, together with their doctor, that the benefits are greater than the risks.

Finally, people with a history of blood clotting should not take a second dose of the AstraZeneca vaccine.

04/07/2021 12:20 GMT — Moderna vaccine offers protection for at least 6 months, study says

A new study finds that, in 33 people who have received the second dose of the Moderna vaccine, antibodies persisted for 6 months.

Dr. Nicole Doria-Rose of the National Institute of Allergy and Infectious Diseases and her team tracked antibody activity in 33 participants who enrolled in the Moderna vaccine trials.

The participants were between 18 and over 71 years old. “Antibody activity remained high in all age groups at day 209,” write the authors. “Our data show antibody persistence and thus support the use of this vaccine in addressing the COVID-19 pandemic,” they conclude.

The paper appears inThe New England Journal of Medicine.

04/06/2021 14:31 GMT — COVID-19 deaths pass 3 million landmark

According to a Reuters assessment, as of Tuesday, April 6, the total number of COVID-19-related deaths worldwide has surpassed 3 million.

This surge in death numbers corresponds to a recent rise in COVID-19 cases in Europe and various countries around the world. In fact, according to Reuters, the highest increase in deaths has been reported in Brazil and India.

In Brazil, health experts attribute the surge in cases and deaths to an emerging SARS-CoV-2 variant called “P.1,” which appears to be more transmissible. The new variant may also increase the risk of death among the younger population.

The global increase in deaths is also worrying, Reuters notes. It took over a year for global COVID-19 deaths to reach the 2 million landmark. However, the third million cropped up in only approximately 3 months, according to the news organization.

04/06/2021 14:25 GMT — Large study finds no link between blood type and COVID-19 severity or risk

A new review of almost 108,000 patients concludes there is no link between blood type and COVID-19 risk or severity. The findings appear in the journal JAMA Network Open.

Dr. Jeffrey Anderson, from Intermountain Medical Center Heart Institute in Murray, UT, and colleagues, set out to investigate more deeply the possible connection between blood type and COVID-19 risk, following reports early on in the pandemic that people with type A blood may be more likely to develop the disease.

In the present study, of the total of 107,796 individuals — who were tested for a SARS-CoV-2 infection and whose blood type was recorded — nearly 11,500 tested positive for the virus. The researchers applied logistic regression analysis to examine the associations between all blood types and disease severity and risk.

“[W]e found no ABO associations with either disease susceptibility or severity,” write the researchers. “Given the large and prospective nature of our study and its strongly null results, we believe that important associations of SARS-CoV-2 and COVID-19 with ABO groups are unlikely,” they conclude.

03/30/2021 11:14 GMT — CDC Director Dr. Walensky warns of fourth surge

During a White House press briefing, Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention (CDC), made an emotional plea urging Americans to “work together now to prevent a fourth surge,” in light of rising COVID-19 cases and hospital admissions.

Dr. Walensky pointed out that the United States had surpassed 30 million COVID-19 cases since the start of the pandemic, that the rate of new cases had increased by 10% compared with the previous 7-day period, and that hospital admissions had gone from 4,600 to 4,800 per day.

“And deaths, which typically lag behind cases and hospitalizations, have now started to rise, increasing nearly 3%, to a 7-day average of approximately 1,000 deaths per day,” she explained.

Dr. Walensky compared this rise in cases to the spikes recently seen in European countries.

“And so I’m asking you to just hold on a little longer, to get vaccinated when you can so that all of those people that we all love will still be here when this pandemic ends,” she urged.

Dr. Walensky also shared the results of a new CDC Morbidity and Mortality Weekly Report (MMWR), which assessed the rate of SARS-CoV-2 infections in 4,000 healthcare staff, first responders, and other essential workers.

“The study found that the risk of infection was reduced by 90% after individuals received the two recommended doses of the vaccine,” Dr. Walensky summarized the results. “The study also found that people starting to get a protective effect, even after the first dose, the risk of infection decreased by 80% after 2 weeks.”

03/25/2021 12:25 GMT — New SARS-CoV-2 variant carrying a double mutation

Scientists in India have identified a number of COVID-19 cases caused by a SARS-CoV-2 variant carrying two mutations in the spike protein. It is currently unclear if this variant is more infectious or causes more severe disease. 

According to the BBC, the variant was present in 20% of cases in the Indian state Maharashtra, which has recently experienced a steep rise in new cases.  

One of the variant’s mutations, E484Q, is similar to E484K. This mutation is familiar from variants that researchers in South Africa and Brazil have found. 

The other mutation, L452R, is also present in variants of the B.1.427/B.1.429 lineage. Scientists in the United States identified this variant of concern, and some people refer to it as the “California variant.”

03/24/2021 09:17 GMT — Experts discuss the recent furor surrounding the AstraZeneca vaccine

Yesterday, the National Institute of Allergy and Infectious Diseases (NIAID)released a statement regarding the AstraZeneca vaccine. The NIAID reported that the Data and Safety Monitoring Board (DSMB) had “expressed concern” that AstraZeneca may have included “outdated information” from their clinical trial in the United States.

This, they explain, might have provided an incomplete view of the efficacy data.

Dr. Peter English, a retired consultant in communicable disease control says: “There is a single sentence behind this story: ‘The DSMB expressed concern that AstraZeneca may have included outdated information from that trial, which may have provided an incomplete view of the efficacy data.’ I find this problematic in various ways. It reads like a sentence from the conclusions of a paper but one that has been presented out of context, without any explanation of the reasons for drawing the conclusion or of what they think the consequences might be.”

He continues: “If you present data, stating the period in which the data were collected, how can the data be ‘outdated’[?] The AstraZeneca press release did say it was on ‘interim’ data. There may be more recent data, but that would not normally outdate or invalidate the interim results.”

Dr. English calls the National Institutes of Health (NIH) communication “shamefully bad” and worries that it might increase vaccine hesitancy.

03/23/2021 16:43 GMT — Israel and New Zealand approve Nitric Oxide Nasal Spray

This week, officials in Israel and New Zealand have provided interim approval for the sale of nitric oxide nasal spray (NONS). The product is manufactured by SaNOtize Research and Development. According to the company, the spray could help reduce transmission of SARS-CoV-2.

Nitric oxide has antimicrobial properties and can kill SARS-CoV-2. NONS works by targeting the virus in the upper airways, which prevents it from reaching the lungs. Because doctors have used nitric oxide as a treatment for many years, there are few safety concerns.

In a press release, SaNOtize outline the findings from a recent clinical trial. The trial included data from 79 people with confirmed COVID-19. The researchers concluded that NONS reduced the viral load by more than 95% in 24 hours and by 99% in 72 hours.

According to Chris Miller, Ph.D., the chief science officer and co-founder of SaNOtize: “NONS destroys the virus, blocks entry into and halts viral replication within the nasal cavity, which rapidly reduces viral load. This is significant because viral load has been linked to infectivity and poor outcomes.”

03/12/2021 09:22 GMT — More P.1 variants detected in England

Yesterday, Public Health England announced that they had detected four more cases of the “variant of concern” VOC-202101/02. Also called P.1, the variant was identified in Gloucestershire and Bradford. In all, officials have now detected 10 P.1 cases in the United Kingdom.

“We shouldn’t pay too much attention to each day’s numbers,” explains Dr. Jeffrey Barrett, director of the COVID-19 Genomics Initiative at the Wellcome Sanger Institute, in Hinxton, England. He continues:

“As we increase our sequencing capacity, we will continue to find infections with known and new variants of concern. Because cases are coming down, we are finding a larger proportion of all such infections each week — for instance, we’ve sequenced more than 20% of new cases for the past 2 weeks. This gives us the best possible chance to monitor and contain these variants.”

“It is no surprise that additional cases of infection with the P.1 variant [which originated in Brazil] have been identified,” says Prof. Lawrence Young, a professor of molecular oncology at the Warwick Medical School, in the U.K.

“This is a highly infectious variant, which is fueling the surge of infections in Brazil. […] Aside from this [variant] being more contagious, it is also likely to be partially resistant to current vaccines and may also be able to reinfect individuals who were previously infected with a different variant.” 

Prof. Young explains the importance of reducing the spread of this variant, for instance by “ensuring strict border control measures and efficient surge testing to trace and isolate infected individuals and their contacts.”

03/10/2021 08:48 GMT — Unhealthy heart may increase risk of COVID-19 diagnosis

The results of some studies suggest that a SARS-CoV-2 infection might impact heart health. However, a recent study published in the journal Aging Clinical and Experimental Research concludes that the relationship might be the other way around: People with poorer functioning hearts are more susceptible to COVID-19.

Lead researcher Dr. Zahra Raisi-Estabragh explains the findings:

“In this research, we’ve discovered that poorer heart structure and function is linked to a higher risk of subsequent COVID-19. This is important because some studies have suggested that COVID-19 may cause structural damage to the heart. However, these studies only use heart scans from people after infection, so they cannot be certain whether the poor heart structures preexisted COVID-19.”

She continues: “In our study, we used imaging data obtained before COVID-19, and showed that many of these abnormalities likely preexist and predispose people to COVID-19 rather than occur as a result of infection. This is a very important distinction for guiding our management of patients with COVID-19.”
