The article you just read was brought to you by a few thousand dedicated readers. Will you join them?

Thanks for coming by The Tyee and reading one of many original articles we’ll post today. Our team works hard to publish in-depth stories on topics that matter on a daily basis. Our motto is: No junk. Just good journalism.

Just as we care about the quality of our reporting, we care about making our stories accessible to all who want to read them and provide a pleasant reading experience. No intrusive ads to distract you. No paywall locking you out of an article you want to read. No clickbait to trick you into reading a sensational article.

There’s a reason why our site is unique and why we don’t have to rely on those tactics — our Tyee Builders program. Tyee Builders are readers who chip in a bit of money each month (or one-time) to our editorial budget. This amazing program allows us to pay our writers fairly, keep our focus on quality over quantity of articles, and provide a pleasant reading experience for those who visit our site.

In the past year, we’ve been able to double our staff team and boost our reporting. We invest all of the revenue we receive into producing more and better journalism. We want to keep growing, but we need your support to do it.

Fewer than 1 in 100 of our average monthly readers are signed up to Tyee Builders. If we reach 1% of our readers signing up to be Tyee Builders, we could continue to grow and do even more.

No COVID Spread at Open-Air Football Games with Limited, Masked Attendance

And other pandemic news from science journals.

Brian Owens 24 Aug 2021 | TheTyee.ca

Brian Owens is a freelance science writer and editor based in St. Stephen, New Brunswick. His work has appeared in Hakai Magazine, Nature, New Scientist, the Canadian Medical Association Journal and the Lancet.

Compiled by veteran medical journalist Brian Owens, this roundup of some of the newest science on the COVID-19 pandemic, straight from the scientific journals, is presented by Hakai Magazine in partnership with The Tyee.

Vaccine stockpiling could lead to more infections and new variants

Stockpiling vaccines for booster shots by rich countries like Canada will undermine global health by increasing infections, hospitalizations and deaths from COVID-19 in countries with less access to vaccines — and could lead to the emergence of new, more dangerous variants of the virus.

Researchers used mathematical models to investigate the spread of COVID-19 under different vaccine-sharing regimes. They found that increased sharing between high-access and low-access regions reduced the number of cases overall. They also found that without vaccine sharing, the potential for new variants of the virus to evolve was much higher.

Why kids are more resistant to COVID-19

Differences in gene expression and immune cells in the noses of children may help explain why they are less susceptible to COVID-19 than adults. Researchers found that children under the age of 16 had higher levels of receptors that could detect the virus, and more infection-fighting immune cells in their nose, resulting in a stronger early immune response to SARS-CoV-2.

No spread from football games with limited attendance

NFL and NCAA football games held with limited in-person attendance in the 2020-21 season did not cause an explosion in COVID-19 cases in the surrounding communities. Places that held in-person games saw fewer than five extra cases per 100,000 people compared with places that held games with no fans. Researchers suspect that limited attendance, strict mask use and open air helped to prevent the spread of the virus.

Vaccine antibodies work against the Delta variant

Despite the surge in infections caused by the Delta variant of SARS-CoV-2, it turns out that Delta is not particularly good at evading the antibodies produced by vaccination. Researchers looked at a panel of 13 different antibodies generated by the Pfizer-BioNTech vaccine and found that 12 of them could still recognize the Delta variant, and the five that could neutralize the original strain could also neutralize Delta. The antibodies were less effective at recognizing and neutralizing the other, less common variants of concern, including Alpha, Beta and Gamma.

Aerosol transmission is more important than contaminated surfaces

Virus transmission via airborne aerosol particles is much more efficient than transmission by fomites — droplets on contaminated surfaces — and causes more severe disease according to a study on hamsters. Researchers found that the animals exposed to aerosols were much more likely to get infected than the fomite group, and lung damage was more severe in aerosol-exposed animals compared to the fomite group. The results suggest that interventions to reduce indoor airborne transmission of the virus, such as masking, air filtration and social distancing, are more important than surface cleaning.

Ads featuring doctors and nurses helped reduce COVID-19 cases

Facebook ads that featured doctors and nurses urging people to stay home during the holidays in 2020 contributed to a decrease in COVID-19 cases in the two-week period after Thanksgiving and Christmas in the United States. In places where lots of people saw the ads, they reduced the distance they travelled in the three days leading up to the holiday, and COVID-19 cases dropped by 3.5 per cent.

Convalescent plasma doesn’t stop COVID-19

Convalescent plasma — purified blood from people who have already been infected with SARS-CoV-2 — is not effective at preventing the progression of COVID-19, according to a new study. Blood from people who have recovered from their illness should contain antibodies to the virus, and is often the first, best option for treatment early in a pandemic. But a large, randomized trial found that it was not a viable strategy to reduce the severity of illness for COVID-19.
