Moderna shot protects against new virus variants; higher blood thinner dose keeps patients off ventilators

Published

By Nancy Lapid

(Reuters) – The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.

 

Moderna vaccine protects against new variants

The COVID-19 vaccine from Moderna Inc protects against the new virus variants found in Britain and South Africa, researchers reported on Monday on bioRxiv ahead of peer review. They found no reduction in the effect of vaccine-induced antibodies on the UK variant. They did see significantly reduced effectiveness of the antibodies on the South Africa variant, although Moderna still believes its two-dose vaccine will provide protection. The company said it will test a new booster shot aimed at the South Africa variant that could be made available if necessary. Dr. Paul Offit of the University of Pennsylvania, a member of the U.S. Food and Drug Administration’s vaccine advisory panel, said he was only mildly concerned that the vaccine would not protect against the variants. “It is a little worrisome that you see a lesser neutralizing antibody response,” he said, but even these lower levels may still be enough to protect against serious infections. “The goal of this vaccine is to keep you out of the hospital and to keep you out of the morgue. If you get a symptomatic infection or mildly symptomatic infection that is not a burden to the healthcare system,” Offit said. (https://bit.ly/3ocFUBD; https://reut.rs/2Mj0Z06)

 

Full-dose blood thinners help keep patients off ventilators

A trio of trials has found that giving full-dose blood thinning treatments to moderately ill patients hospitalized for COVID-19 reduced their need for vital organ support, such as mechanical ventilation, the U.S. National Institutes of Health (NIH) announced on Friday. Blood clotting is a serious problem in COVID-19. The three trials, conducted at more than 300 hospitals on four continents, tested whether there is a greater benefit to administering a full dose of the blood thinner heparin compared to the lower dose typically used to prevent blood clots in hospitalized patients. In December, the researchers reported that the higher dose was harmful in patients already on life support. The new data show “that when we give higher doses of blood thinners to patients who are not already critically ill, it is beneficial and should become standard of care,” study leader Matthew Neal of the University of Pittsburgh said in a statement. The researchers said the cheap, readily available treatment could help reduce the burden on intensive care units. The trials also suggest a possible survival benefit with full-dose heparin in patients not yet on life support, but that needs further study, the NIH said. The agency has not released the complete study data. (https://bit.ly/39j1BMp)

 

Lifetime smoking history linked with COVID-19 death risk

Former smokers who have quit still face higher risks from COVID-19 than never-smokers, a new study shows. Researchers at the Cleveland Clinic Health System in Ohio and Florida studied 7,102 COVID-19 patients, including 6,020 never smokers, 910 former smokers, and 172 current smokers. The risk of hospitalization and death went up with the cumulative amount patients had ever smoked and the increases in risk were similar for current smokers and former smokers, researchers found. Those who had smoked the most – the equivalent of a pack a day for 30 years, or two packs a day for at least 15 years – had 2.25 times higher odds of hospitalization and were 89% more likely to die following a COVID-19 diagnosis when compared with never smokers, the researchers reported on Monday in JAMA Internal Medicine. Lifetime tobacco smoking history is therefore linked with risk for hospital admission and death from COVID-19, the research team concluded, adding that illnesses typically linked with smoking, like heart and lung diseases, probably contributed to those poorer outcomes.

One-in-three with COVID-19 may not know it

At least one third of people infected with the highly contagious coronavirus may not realize it, a new report warns. Some of them are “presymptomatic,” meaning they have no symptoms but will eventually develop them. Others will remain asymptomatic for the duration of their infection. “Infection without symptoms … is important because infected persons can transmit the virus to others even if they have no symptoms,” the researchers said on Friday in Annals of Internal Medicine. They analyzed data from 43 studies that used gold-standard PCR testing to diagnose COVID-19 and 18 that used antibody testing to look for evidence of previous infection. These studies “provide compelling evidence that the asymptomatic fraction of SARS-CoV-2 infection is sizable,” they said. The researchers called for new strategies to control the spread of the virus, such as “inexpensive, rapid home tests to identify and contain presymptomatic or asymptomatic cases, along with government programs that provide financial assistance and, if necessary, housing to enable infected persons to isolate themselves.” It will be important to know whether vaccines are preventing asymptomatic infections, they said.

COVID-19 in B.C.: 10 deaths, Dr. Bonnie Henry and Health Minister on threats and personal attacks, and more – Straight.com

Published

 on


B.C. continues to remain in a risky period for sudden increases in COVID-19 case numbers.

At today’s briefing from Vancouver, B.C. provincial health officer Dr. Bonnie Henry said the weekly average for new cases has slightly increased in recent weeks, more so in the Lower Mainland region (and particularly in Fraser Health).

She said an upward trend in the virus reproductive number indicates that there remains “potential for rapid growth if we’re not careful”, particularly in the Lower Mainland.

Henry said that “we’re not quite there yet” for relaxing restrictions but that they are looking ahead into March to figure out when there could be potential for that.

B.C. Health Minister Adrian Dix pointed out that after the winter holiday season, there was a significant increase in cases and hospitalizations in Interior Health but that has since decreased over the past few weeks.

“It shows again what we can do together as communities,” he said.

In January, there were a number of incidents of police shutting down parties and makeshift nightclubs in Surrey, Richmond, and Vancouver that were violating provincial health orders.

That has since given way to a handful of increasingly vocal or violent examples of individuals resisting health measures, including:

  • a few incidents involving male customers yelling and refusing to leave businesses after being denied service for not wearing a mask, including one in Kerrisdale, and another in Burnaby;
  • a male suspect physically assaulting another gym user who had asked him to wear a mask at a Downtown Vancouver gym;
  • two female passengers being arrested in Nanaimo and fined over $900 for yelling and verbally abusing staff aboard a B.C. Ferries sailing after they refused to wear masks aboard the ship;
  • a male customer allegedly assaulting and then becoming embroiled in a physical altercation with staff at Canadian Tire in Burnaby as they tried to handcuff him after he refused to wear a mask or leave the premises;
  • a male suspect allegedly stabbing a 50-year-old man during a fight that erupted after the victim’s daughter asked the suspect to physically distance in a Nanaimo parking lot.

Meanwhile, the antimask protest movement continues on with rallies, including one held in Vancouver last weekend (February 20).

In addition, the B.C. Supreme Court also denied a request from Henry and the province for an injunction against three churches in the Fraser Valley that are continuing to hold in-person services in defiance of provincial health orders. Those churches are also attempting to take legal action to overturn provincial health orders that prohibit church services from being conducted indoors.

Henry had previously spoken in September about abusive phone calls and letters, as well as death threats, that she has faced over the course of the pandemic.

When she was asked at today’s news conference about how she is dealing with threats and protests, Henry said that the part that she finds most challenging and disturbing is how it affects the people around her, including the people she works with and her family, but she added that they do have strong support systems.

She said her colleagues across the country, who are contending with similar issues, meet regularly and they support each other.

Henry did offer some insight into the psychology of those who are acting out in emotional or extreme ways.

“I recognize that when people are in crises, part of the way they respond or react is to lash out, to become angry,” she said. “That is a reaction that is sometimes fed by certain groups, by certain media, social media posts, et cetera, and it’s not to condone it but it’s to recognize the psychology of what we’re dealing with leads some people to react that way.”

She said “our collective support for each other that helps mitigate the impact of these things”.

However, she said it “really is not unacceptable”, and Dix agreed with that sentiment.

“We live in a democratic society and it is absolutely legitimate to disagree, even about issues such as the pandemic, but some of the disagreement is totally unacceptable,” he said. “Dr. Bonnie Henry is an extraordinary leader and that doesn’t mean she’s right all the time…but the kind of personal attacks on some of them are completely unacceptable.”

He condemned threats made against Henry, and pointed out how she never loses sight of people and shows compassion “for every single person” during the pandemic despite all of the criticism she receives.

“We need to have a slightly more respectful debate,” he said. “All of us have to find ways to disagree without personal attack.”

Henry announced that there are 395 new cases (including 12 epi-linked cases) in B.C. today, which includes:

  • 207 new cases in Fraser Health;
  • 86 in Vancouver Coastal Health;
  • 41 in Northern Health;
  • 37 in Island Health;
  • 24 in Interior Health;
  • no one from outside of Canada.

At the moment, there are 4,489 active cases, which is a drop of 179 cases since yesterday.

Hospitalized cases also decreased—with nine patients discharged since yesterday, 228 individuals are currently in hospitals, and 62 of them are in intensive care units (two fewer patients since yesterday).

Public health is monitoring 7,931 people for exposure to identified cases, which is only seven more people since yesterday.

Unfortunately, the number of deaths has risen. There are 10 new COVID-19-related deaths. The cumulative total of number of fatalities during the pandemic is now at 1,348 people who have died in B.C.

With 562 more recoveries since yesterday, a cumulative total of 72,781 people have now recovered.

During the pandemic, B.C. has recorded a total of 78,673 cases.

Since the last variant update on February 22, there have been 16 new confirmed COVID-19 variant cases, bringing the total to 116 cases.

By region, that includes:

  • 71 cases in Fraser Health;
  • 39 in Vancouver Coastal Health;
  • four in Island Health;
  • two in Interior Health.

Of the total cases, nine cases are active and the remaining people have recovered.

So far, the total cases include:

  • 95 of the B117 variant (U.K.);
  • 21 of the B131 variant (South Africa);
  • two of the B1525 variant (Nigeria), which Henry said is still a variant under investigation.

Henry said the source of transmission remains uncertain for about 25 percent of the cases.

Investigations into variants in schools remain ongoing.

As of today, 239,883 doses of COVID-19 vaccine have been administered in B.C., and 68,157 of them are second doses.

Henry said active outbreaks remain in 13 longterm care facilities and five acute care facilities for a total of 18 outbreaks, involving 611 cases (398 residents and 213 staff members).

There is one new healthcare facility outbreak at the Revera Sunwood Retirement Community in Maple Ridge.

Northern Health gave an update today on the outbreak at Acropolis Manor in Prince Rupert, which was declared on January 19. there is now a total of 56 cases—33 residents and 23 staff, and 14 residents have died.

In Vancouver Coastal Health (VCH), restrictions were lifted today from Unit 9C at St. Paul’s Hospital, where restrictions were imposed on January 4.

In an update today on cases in Whistler, VCH said that transmissions continue to decline. From February 16 to 21, there were 26 new cases (which is 36 fewer new cases than from February 8 to 15). With 671 people having recovered, there are currently 31 active cases left. Since January 1, a total of 702 cases have been confirmed in Whistler.

The B.C. Centre for Disease Control (BCCDC) added seven domestic flights to its list of COVID-19 exposures:

  • February 10: Air Canada/Jazz 8236, Vancouver to Terrace;
  • February 12: Air Canada 115, Toronto to Vancouver;
  • February 14: Air Canada/Jazz 8069, Vancouver to Victoria;
  • February 14: Air Canada/Jazz 8239, Terrace to Vancouver;
  • February 18: Air Canada 106, Vancouver to Toronto;
  • February 20: Air Canada 251, Edmonton to Vancouver;
  • February 21: Flair 8101, Vancouver to Edmonton.

Affected row information can be found at the BCCDC website.

Loblaw stated that several employees (specific number and dates not provided) at the Real Canadian Superstore (6–291 Cowichan Way) in Duncan have tested positive.

The latest provincial projections suggest 40 percent of cases will be COVID variants of concern in Ontario by mid-March and hospitalizations and ICU admissions will likely increase in the coming weeks. But it’s not all bad news according to the health experts advising the government.

“A better summer is in sight, if we work for it now,” said Dr. Adalsteinn Brown who co-chairs the advisory table.

The modelling suggests a third wave is still possible and the drop in cases has bottomed out but are moving up again. Dr. Brown adds the province can keep gains made by watching spread very closely and by loosening public health measures only carefully. In a worst-case scenario, the province could see around 4,000 new cases per-day by the end of March and best case around 1,000 daily.

But Dr. Brown points to positive trends in long term care.

“We have seen a substantial reduction in the daily death rates in long term care homes and a substantial reduction in the cases both among residents and staff.”

Currently there are 42 homes in outbreak with resident cases.
