Pfizer's COVID-19 vaccine effectiveness drops after 6 months: study – CTV News

Published

 on


The effectiveness of the Pfizer Inc /BioNTech SE vaccine in preventing infection by the coronavirus dropped to 47% from 88% six months after the second dose, according to data published on Monday that U.S. health agencies considered when deciding on the need for booster shots.

The data, which was published in the Lancet medical journal, had been previously released in August ahead of peer review.

The analysis showed that the vaccine’s effectiveness in preventing hospitalization and death remained high at 90% for at least six months, even against the highly contagious Delta variant of the coronavirus.

The data suggests that the drop is due to waning efficacy, rather than more contagious variants, researchers said.

Researchers from Pfizer and Kaiser Permanente studied electronic health records of roughly 3.4 million people who were members of Kaiser Permanente Southern California between December 2020 – when the vaccine first became available – and August of 2021.

“Our variant-specific analysis clearly shows that the (Pfizer/BioNTech) vaccine is effective against all current variants of concern, including Delta,” said Luis Jodar, senior vice president and chief medical officer at Pfizer vaccines.

A potential limitation of the study was a lack of data on adherence to masking guidelines and occupations in the study population, which could have affected frequency of testing and likelihood of exposure to the virus.

Vaccine effectiveness against the Delta variant was 93% after the first month, declining to 53% after four months. Against other coronavirus variants, efficacy declined to 67% from 97%.

“To us, that suggests Delta is not an escape variant that is completely evading vaccine protection,” said study leader Sara Tartof with Kaiser Permanente Southern California’s Department of Research & Evaluation.

“If it was, we would probably not have seen high protection after vaccination, because vaccination would not be working in that case. It would start low, and stay low.”

Testing for variants is more likely to fail in vaccinated individuals, which could lead to overestimation of variant-specific effectiveness in the study, the authors cautioned.

The U.S. Food and Drug Administration has authorized the use of a booster dose of the Pfizer/BioNTech vaccine for older adults and some Americans at high-risk of getting infected. Scientists have called for more data on whether boosters should be recommended for all.

Japan’s SoftBank returns to profit after gains at Vision Fund and other investments

Published

 on

 

TOKYO (AP) — Japanese technology group SoftBank swung back to profitability in the July-September quarter, boosted by positive results in its Vision Fund investments.

Tokyo-based SoftBank Group Corp. reported Tuesday a fiscal second quarter profit of nearly 1.18 trillion yen ($7.7 billion), compared with a 931 billion yen loss in the year-earlier period.

Quarterly sales edged up about 6% to nearly 1.77 trillion yen ($11.5 billion).

SoftBank credited income from royalties and licensing related to its holdings in Arm, a computer chip-designing company, whose business spans smartphones, data centers, networking equipment, automotive, consumer electronic devices, and AI applications.

The results were also helped by the absence of losses related to SoftBank’s investment in office-space sharing venture WeWork, which hit the previous fiscal year.

WeWork, which filed for Chapter 11 bankruptcy protection in 2023, emerged from Chapter 11 in June.

SoftBank has benefitted in recent months from rising share prices in some investment, such as U.S.-based e-commerce company Coupang, Chinese mobility provider DiDi Global and Bytedance, the Chinese developer of TikTok.

SoftBank’s financial results tend to swing wildly, partly because of its sprawling investment portfolio that includes search engine Yahoo, Chinese retailer Alibaba, and artificial intelligence company Nvidia.

SoftBank makes investments in a variety of companies that it groups together in a series of Vision Funds.

The company’s founder, Masayoshi Son, is a pioneer in technology investment in Japan. SoftBank Group does not give earnings forecasts.

Trump campaign promises unlikely to harm entrepreneurship: Shopify CFO

Published

 on

 

Shopify Inc. executives brushed off concerns that incoming U.S. President Donald Trump will be a major detriment to many of the company’s merchants.

“There’s nothing in what we’ve heard from Trump, nor would there have been anything from (Democratic candidate) Kamala (Harris), which we think impacts the overall state of new business formation and entrepreneurship,” Shopify’s chief financial officer Jeff Hoffmeister told analysts on a call Tuesday.

“We still feel really good about all the merchants out there, all the entrepreneurs that want to start new businesses and that’s obviously not going to change with the administration.”

Hoffmeister’s comments come a week after Trump, a Republican businessman, trounced Harris in an election that will soon return him to the Oval Office.

On the campaign trail, he threatened to impose tariffs of 60 per cent on imports from China and roughly 10 per cent to 20 per cent on goods from all other countries.

If the president-elect makes good on the promise, many worry the cost of operating will soar for companies, including customers of Shopify, which sells e-commerce software to small businesses but also brands as big as Kylie Cosmetics and Victoria’s Secret.

These merchants may feel they have no choice but to pass on the increases to customers, perhaps sparking more inflation.

If Trump’s tariffs do come to fruition, Shopify’s president Harley Finkelstein pointed out China is “not a huge area” for Shopify.

However, “we can’t anticipate what every presidential administration is going to do,” he cautioned.

He likened the uncertainty facing the business community to the COVID-19 pandemic where Shopify had to help companies migrate online.

“Our job is no matter what comes the way of our merchants, we provide them with tools and service and support for them to navigate it really well,” he said.

Finkelstein was questioned about the forthcoming U.S. leadership change on a call meant to delve into Shopify’s latest earnings, which sent shares soaring 27 per cent to $158.63 shortly after Tuesday’s market open.

The Ottawa-based company, which keeps its books in U.S. dollars, reported US$828 million in net income for its third quarter, up from US$718 million in the same quarter last year, as its revenue rose 26 per cent.

Revenue for the period ended Sept. 30 totalled US$2.16 billion, up from US$1.71 billion a year earlier.

Subscription solutions revenue reached US$610 million, up from US$486 million in the same quarter last year.

Merchant solutions revenue amounted to US$1.55 billion, up from US$1.23 billion.

Shopify’s net income excluding the impact of equity investments totalled US$344 million for the quarter, up from US$173 million in the same quarter last year.

Daniel Chan, a TD Cowen analyst, said the results show Shopify has a leadership position in the e-commerce world and “a continued ability to gain market share.”

In its outlook for its fourth quarter of 2024, the company said it expects revenue to grow at a mid-to-high-twenties percentage rate on a year-over-year basis.

“Q4 guidance suggests Shopify will finish the year strong, with better-than-expected revenue growth and operating margin,” Chan pointed out in a note to investors.

RioCan cuts nearly 10 per cent staff in efficiency push as condo market slows

Published

 on

 

TORONTO – RioCan Real Estate Investment Trust says it has cut almost 10 per cent of its staff as it deals with a slowdown in the condo market and overall pushes for greater efficiency.

The company says the cuts, which amount to around 60 employees based on its last annual filing, will mean about $9 million in restructuring charges and should translate to about $8 million in annualized cash savings.

The job cuts come as RioCan and others scale back condo development plans as the market softens, but chief executive Jonathan Gitlin says the reductions were from a companywide efficiency effort.

RioCan says it doesn’t plan to start any new construction of mixed-use properties this year and well into 2025 as it adjusts to the shifting market demand.

The company reported a net income of $96.9 million in the third quarter, up from a loss of $73.5 million last year, as it saw a $159 million boost from a favourable change in the fair value of investment properties.

RioCan reported what it says is a record-breaking 97.8 per cent occupancy rate in the quarter including retail committed occupancy of 98.6 per cent.
