New top story from Time: Moderna Is Testing a New Version of Its COVID-19 Vaccine That Wouldn’t Require Ultra-Cold Storage

https://ift.tt/3t33uU6

As safety concerns over COVID-19 vaccines from AstraZeneca and Johnson&Johnson–Janssen have led to disruptions in the inoculation efforts of numerous countries relying on those shots, companies like Moderna are attempting to fill the resulting gaps.

The Massachusetts-based biotech company announced on April 29 that it is investing billions to boost manufacturing facilities in Switzerland, Spain and the U.S., building enough capacity to produce up to 3 billion doses of its mRNA-based vaccine through 2022. The company’s vaccine technology differs from that of AstraZeneca and J&J, which both use an adenovirus to deliver COVID-19 virus genes to the immune system—and which both have been have been associated with serious, life-threatening—albeit very rare—blood clots.

Stephane Bancel, CEO of Moderna, says that some of the wealthier, developed countries are eager to up their orders of the mRNA vaccines (which include both the Moderna shot and one produced by Pfizer/BioNTech). “In the last month or so, in the discussions we have had with heads of state, prime ministers, presidents of countries and health ministers, when governments look at efficacy, safety, manufacturing scalability, and the speed to the next generation of vaccines, what we are hearing loud and clear is that mRNA is the best for the problem at hand,” says Bancel. “And governments around the world want more and more mRNA product.”

To meet that need, and the needs of facilities in less-resourced countries that don’t have the freezer capabilities required to store the company’s vaccine currently, Bancel says that his scientists are studying a new version of the Moderna vaccine that won’t need to be frozen, and instead would simply need to be kept under refrigerated conditions for up to three months. Right now, it can only be stored at those temperatures for one month after the doses are thawed from their frozen storage temperature of about -20°C (14°F)—which requires special equipment that is not widely available. If the studies show the new vaccine could be stable and efficacious at refrigerated temperatures, that could increase the number of places that could vaccinate with Moderna’s shot.

“We played with a couple of key technological decisions and it is indeed a very different product,” says Bancel about the refrigerated version, which the company has just started testing in people. That means efficacy data won’t be available until the end of summer at the earliest; the company is working with the FDA to figure out what the authorization process would look like for that vaccine.

Meanwhile, the company is also studying three new versions of its COVID-19 vaccine to address viral mutations. One is specifically designed to protect against a more infectious variant of the virus, B.1.351, first identified in South Africa. The current Moderna vaccine has been shown in studies to bestow sufficient protection against this variant, but that protection is slightly lower than that provided against the original viral strain, and Moderna researchers are testing if the new shot activates a stronger immune response against the B.1.351 variant. Studies in animals are promising and human studies have just begun, so by early fall, says Bancel, “we expect the data [for the new vaccine] in humans to be as strong as what we saw last year with the current vaccine.”

The Moderna team is also testing whether a third shot of its currently authorized vaccine—at a lower dose than the first and second shots—could be effective as a booster, to increase protection against variant strains. And finally, the company is also testing a vaccine that combines the original vaccine with the new one against the South African variant.

Looking ahead, some public health experts believe controlling COVID-19 may require regular vaccinations, similar to flu shots, to maintain immune protection. Anticipating that, Moderna scientists are also working on a combined flu and COVID-19 shot that would protect people against both respiratory diseases.

Powered Scooters Charge City’s Transportation Recovery

Powered Scooters Charge City’s Transportation Recovery By Jason Hyde The SFMTA is releasing its next round of Powered Scooter Share permits on July 1. Scooters remain a sustainable mode of travel and a complement to Muni and public transit service as the city recovers from the pandemic and San Franciscans begin to travel more. The SFMTA’s Powered Scooter Share Program is essential in ensuring that shared scooter operations support the city’s economic recovery in a safe, sustainable, and equitable way.  The SFMTA received four submittals for the permit program and will issue permits to two operators : Spin and Lime. Permits will be in effect for a one-year term, with the option to extend for another year at the discretion of the SFMTA based on compliance with various program metrics. While the new permit program does not set a limit on the number of scooters each operator may deploy, it does limit the overall citywide fleet size at 10,000. Starting at a base of 2,000 scooters...

What a Year It Has Been! Let the Celebration of Transit Month Continue

What a Year It Has Been! Let the Celebration of Transit Month Continue By Erin McMillan 49 Van Ness/Mission using the brand new bus rapid transit lanes on opening day in April. During Transit Month this September, we’re continuing the celebration by looking back to more of the work we’ve done over the last year— some that has been less obvious to Muni customers, but critical to a well-functioning system and other work that is more front and center. Fix It! Week and Continuing State of good Repair Work Muni is an impressive transit system. Moving thousands of people on rail and buses every day takes a lot of coordination and a lot of work. Dealing with unique challenges like San Francisco’s geography and shifting travel patterns, we also have to deal with issues related to the Muni system’s age. Proper care and maintenance of a transit system many decades old takes strategic planning as regular maintenance needs to happen while continuing to provide service. Typically, regular Mun...

Permanent Relief for Muni Customers in SoMa?

Permanent Relief for Muni Customers in SoMa? By Erin McMillan Shortly after the pandemic’s onset, the SFMTA implemented Temporary Emergency Transit Lanes to make sure essential trips on Muni wouldn’t get caught in traffic. On Mission Street from 11th to 3rd streets in SoMa , the transit lanes have proven effective at protecting Muni travel times while traffic has increased. Now, with the city’s reopening generating even more traffic, keeping these lanes on the road permanently is as important as ever. Paint Shop Crew Removing Old Pavement Markings for Installation of Transit Only Lanes on Mission Street on September 23, 2020 What’s Next? Given that the data shows the lanes are effective, the SFMTA is now pursing making the full-time transit lanes, and their benefits, permanent. Following up on our initial evaluation of the project, we are now inviting the community to learn about next steps for making the lanes permanent. We are hosting a two-week virtual open house where you ca...

New Customer Information System Signs Coming to a Transit Shelter Near You!

New Customer Information System Signs Coming to a Transit Shelter Near You! By Kharima Mohamed As part of the Next Generation Customer Information System project, over 700 new Liquid Crystal Display (LCD) signs will display real-time information at Muni transit shelters. Approximately one-third of these signs will be double-sided to provide additional visibility at the highest-ridership stops and major transfer points. This week we installed a single-sided prototype at Eddy and Larkin streets. Serving the Tenderloin, an Equity Neighborhood , this sign will feature real-time predictions for the 19 Polk and 31 Balboa routes. The primary purpose for installing this prototype is to conduct in-field hardware testing, especially with rain, wind and colder temperatures.    We know there is an urgent need for more effective signage and are excited to roll out the new customer information system later this year.  The new LCD signs will eventually replace all existing Next...

The Future of Slow Streets

The Future of Slow Streets By Eillie Anzilotti Over the past two years, Slow Streets have shown how simple designs that prioritize people can transform streets. Suddenly, streets across San Francisco filled with the sounds of kids playing and neighbors chatting. They filled with people on bicycles and people rolling in wheelchairs; with joggers and dog-walkers. The streets came to life. Initially, the SFMTA introduced Slow Streets as an emergency response to COVID-19. People needed space for recreating at a safe distance outdoors. And with Muni service reduced or suspended at the time, people needed ways to travel to essential destinations on foot or bike. To quickly meet these early pandemic needs, we implemented Slow Streets with simple signs and barricades. Over time, it became clear that Slow Streets served an even larger purpose. They became places for communities to come together. Neighbors organized events like scavenger hunts and Trick or Treat parties around their local Sl...

New top story from Time: How the GameStop Trading Surge Will Transform Wall Street

https://ift.tt/3a6hpB2 For years, professional money managers and hedge funds have tsk-tsked about individual investors. They have dismissed them as “dumb money” and cautioned that so-called “retail” investors lack the acumen and experience to make the right calls and weather the inevitable storms. That has often been the case, but then came the GameStop phenomenon , when a tsunami of that so-called dumb money flooded parts of the stock market, leaving Wall Street professionals not just scratching their heads but a few of them badly wounded . And while this might be an anomaly, it more likely is the first rumbling of what will prove to be radical transformation of money and markets. In less than a week, shares of the company GameStop rose more than seventeen-fold by the end of trading on January 27 after its prospects were touted two weeks ago on a Reddit sub-group called r /wallstreetbets that has several million subscribers. GameStop, a retail chain that started as a hu...

Geary Boulevard Improvement Project Update

Geary Boulevard Improvement Project Update By Amy Fowler Geary Boulevard is a critical east-west arterial and one of the busiest bus corridors in North America, connecting downtown San Francisco to the Richmond District. The SFMTA has been busy working on the second phase of planned improvements on Geary, called the Geary Boulevard Improvement Project , to improve Muni’s 38 Geary bus service and address traffic safety between 34th Avenue and Stanyan Street.  The project is building on the success of the Geary Rapid Project , which was recently completed on time and on budget and has already shown promising travel time savings on the eastern half of the Geary corridor.    Last fall, we asked neighbors in the Richmond about their priorities for transit, safety and driving issues on Geary via pop-up events on the corridor and a Virtual Open House. Thanks to input from over 600 community members , the SFMTA has used this feedback to draft the detailed, block-by-bloc...

SFMTA to Replace All Parking Meters in the City

SFMTA to Replace All Parking Meters in the City By Jessie Liang San Franciscans will see new parking meters on city streets beginning in early March 2022. Staff from the SFMTA’s Parking Meter Shop will replace the meters at all the nearly 27,000 paid parking spaces in the city because those meters have reached the end of their useful lives, and because many of the meters rely on 3G communications technology that soon will be phased out by the wireless companies. The first new meters will be installed in the South of Market and Mission Bay neighborhoods.  SFMTA staff will provide notices on vehicle windshields when the new meters are activated.  The new meters will provide several benefits, including larger and more legible screens, more intuitive user interface, more powerful batteries, and more resistance to vandalism.   The following neighborhoods will move to a pay-by-license-plate system with new paystations. South Beach SoMa Mission Bay Civic Center H...
