Sanofi and GSK sign agreements with the Government of Canada to supply up to 72 million doses of adjuvanted COVID-19 vaccine
LONDON and PARIS, Sept. 22, 2020 /CNW/ - Sanofi and GSK have today signed agreements with the Government of Canada for the supply of up to 72 million doses of an adjuvanted COVID-19 vaccine, beginning in 2021. Thomas Triomphe, Executive Vice President and Global Head of Sanofi Pasteur, said: " Today’s announcement showcases our unwavering commitment to develop a COVID-19 vaccine that is available to everyone when it comes to market. To address a global health crisis of this magnitude, it takes partnerships and we are grateful to Canada for their collaboration, and to GSK for partnering with us to develop a safe and effective vaccine." Roger Connor, President of GSK Vaccines said: "GSK is proud to be working in partnership with Sanofi to make this vaccine available as soon as possible in Canada. Both companies have significant R&D and manufacturing capability world-wide and are already working hard to scale up production. This announcement from the Government of Canada supports our ongoing efforts." Both companies have vaccine manufacturing sites in Canada that are contributing to overall global COVID-19 vaccine development, and these plus their global industrial networks will play a pivotal role in the production of the COVID-19 vaccine doses for Canada – as agreed today. The Companies initiated a Phase 1/ 2 study on 3rd September and anticipate first results in early December 2020, to support the initiation of a Phase 3 study before the end of the year. If these data are sufficient for licensure application, it is planned to request regulatory approval in the first half of 2021. In parallel, Sanofi and GSK are scaling up manufacturing of the antigen and adjuvant with the target of producing up to one billion doses in total per year globally.

Flu Season Will Be a Test Run for the U.S.’s Biggest-Ever Vaccine Campaign
Denver, CO - Mobile vans, vaccine strike teams and drive-throughs will take the place of traditional tactics to get shots to the public. This fall, the U.S. will need to vaccinate huge numbers of Americans in the middle of a public-health crisis. It will also be a valuable dry run should a coronavirus shot arrive months later.The annual U.S. flu vaccine campaign has been cast into disarray by Covid-19, with people staying away from pharmacies, schools, offices, hospitals and other places where they typically get their shots. But with fears of a flu surge colliding with the coronavirus pandemic, health authorities are looking at how one vaccine effort can inform the other. In Denver, public-health officials are trying to increase the number of adults who get the flu vaccine this year to 65% from 45%. To do it, they’re setting up “strike teams” that can go from school to school giving vaccines, vans that can stop at construction sites and inoculate workers, and doing outreach to hard-to-reach communities.

CDC and drug-makers boost flu vaccine doses for upcoming season
GA - Experts are girding for coronavirus and influenza hitting at the same time
Worried about a simultaneous assault of the novel coronavirus and
seasonal influenza this winter, public health officials and vaccine
manufacturers are making millions of extra flu vaccine doses to protect those
most vulnerable to the pandemic and influenza, according to government and
company officials. Even though flu season doesn’t begin until the fall, major
flu vaccine manufacturers say they plan to boost production by about 10 percent,
to about 189 million doses, up from 170 million doses last year, to ensure
enough doses exist for an anticipated surge in people seeking flu shots. The
Centers for Disease Control and Prevention has taken the rare step of buying 7
million doses directly from manufacturers to be distributed to states for adult
vaccination, CDC Director Robert Redfield said in an interview. “This
is a big move,” he said. That’s about 14 times the 500,000 doses the agency
typically purchases for adults. The adult doses are included in the industry’s
total planned production.

barriers to adult influenza vaccination in Canada
Toronto, ON – Vaccination against influenza is critical to the health and functional ability of Canadian seniors as well as people with chronic disease, who are at higher risk of morbidity, mortality and prolonged recovery due to underlying frailty and changes in immune function. For these reasons, the International Federation on Ageing (IFA) is ramping up efforts to end immunization inequality in Canada and around the world. The IFA launched a report identifying five major barriers to adult influenza vaccination in Canada:
· Lack of a national vaccination schedule
· Absence of consistent messaging
· Inadequate access and availability to more effective vaccines
· Lack of comprehensive influenza surveillance and vaccination data
· InequityThe focus of the report is on influenza vaccination for Canadian seniors, given the devastating and costly impact the disease has on at-risk groups. The IFA is encouraging patient organizations, healthcare providers, families and employers to come together on the issue to place adult immunization on their agenda.

Study finds vaccine
effectiveness reduces hospitalizations in elderly
Atlanta, GA - Vaccination is the best way to prevent influenza; however, greater benefits could be achieved. To help guide research and policy agendas, researchers here, led by Michelle M Hughes, aimed to quantify the magnitude of influenza disease that would be prevented through targeted increases in vaccine effectiveness (VE) or vaccine coverage (VC). For 3 influenza seasons (2011–12, 2015–16, and 2017–18), researchers used a mathematical model to estimate the number of prevented influenza-associated illnesses, medically attended illnesses, and hospitalizations across 5 age groups. Compared with estimates of prevented illness during each season, given observed VE and VC, we explored the number of additional outcomes that would have been prevented from a 5% absolute increase in VE or VC or from achieving 60% VE or 70% VC. They concluded that small, attainable improvements in effectiveness or VC of the influenza vaccine could lead to substantial additional reductions in the influenza burden. Improvements in VE would have the greatest impact in reducing hospitalizations in adults aged ≥65 years, and VC improvements would have the largest benefit in reducing illnesses in adults aged 18–49 years.For more information: https://tinyurl.com/y2dkmg
B.C. seniors face up to 2-month wait for more effective flu vaccine
Victoria, BC - Seniors in B.C. will have to wait longer for a flu vaccine that offers them better protection, because the province doesn't cover the vaccine, according to the vaccine's manufacturer. The Fluzone High-Dose vaccine isn't expected to land on shelves in B.C. until the end of November or early December, the B.C. Pharmacy Association said Tuesday. Fluzone High-Dose vaccine produces a stronger immune response in seniors who are vulnerable to the flu. Standard vaccines are expected to arrive in October. The vaccine, which Health Canada approved in 2015 for use in people aged 65 and older, contains four times the antigen of a standard flu vaccine and produces a stronger immune response in seniors. A 2014 study found the high-dose vaccine to be 24 per cent more effective in preventing the flu than standard vaccines in adults 65 or older. Seniors are more vulnerable to the flu because of their weaker immune systems. Adults 65 and older accounted for up to 90 per cent of seasonal flu-related deaths in recent years, and up to 70 per cent of seasonal flu-related hospitalizations, according to the U.S. Centers for Disease Control and Prevention. B.C. covers standard flu vaccines but does not publicly fund the high-dose version. Pharmacies in the province charge $75 for the shot.The vaccine's manufacturer, Sanofi Pasteur, said it prioritizes delivery of vaccines to provinces and territories that publicly cover the vaccine, including Ontario, Manitoba, Saskatchewan, Northwest Territories, Nova Scotia and Prince Edward Island. Ontario is the only province that offers the vaccines to all seniors. The other provinces and territories distribute the vaccines to people living in long-term care.

Very difficult flu season on the horizon
Toronto, ON - Health ministry says it has ordered 300,000 more high-dose flu vaccines for this year. This year's flu season will likely be a bad one, Ontario's health minister said Monday, and the province is stocking up on extra high-strength vaccines in preparation. "We expect that it's going to be a very difficult year," Christine Elliott said after an unrelated announcement. "Based on what's happening in Australia we sort of take a look at what's likely to happen in Ontario." Australian health authorities are reporting an early flu season — unusually high activity for this time of year. Though the overall severity is reported as low, hospitalizations are three times what is normal for this time, and there have been more than 200 deaths so far, according to that country's department of health. Ontario has already ordered 300,000 more doses of high-dose flu vaccines than last year, bringing the total order to 1.2 million doses, said a spokesman for Elliott. 'The anti-vaxxer theory is out there' That vaccine has four times the amount of antigens than the regular flu shot and is given to more vulnerable people, such as seniors. It can be provided in hospitals, long-term care homes and by primary care providers. Elliott said it was proven particularly effective last year, and that the government will also be rolling out an advertising campaign, encouraging people to get the flu shot. "It's really important to prevent it in the first place, but we also need to be prepared to deal with it when it does strike Ontario, both in terms of hospital care, home care and community care," she said. "We will be advertising to people that we want them to get out and get the flu shot and deal with some of the myths out there about getting the flu vaccine because ... the anti-vaxxer theory is out there as well as far as the flu vaccine is concerned, too." Elliott did not yet have a specific date when the flu shot will be available, but she said it will be well in advance of flu season. Researchers reported early this year that the previous flu season's vaccine appeared to be highly effective. The analysis by researchers with the Canadian Sentinel Practitioner Surveillance Network and published online in the journal Euro Surveillance, shows it was 72 per cent effective in preventing infection with the H1N1 respiratory virus overall across all age groups. In the 2018-19 flu season, 34 per cent of adults in Canada aged 18-64 got the flu shot, and 70 per cent of seniors got it, according to the Public Health Agency of Canada.

Flu shot OK for cancer patients on checkpoint inhibitors
A study, reported in MedPage Today, examined incidence of immune-related adverse events after flu vaccination. For cancer patients receiving treatment with immune checkpoint inhibitors for cancer, there was no increase in incidence of immune-related adverse events after receiving the flu shot, researchers found. No increase in incidence or severity of immune-related adverse events occurred in these advanced stage cancer patients, mostly with lung cancer and melanoma, within 2 months after receiving the inactivated influenza vaccine (IIV), reported Mini Kamboj, MD, of Memorial Sloan-Kettering Cancer Center in New York City, and colleagues.For more information: https://tinyurl.com/y3wyoq6l
