Buy Vaccines Revealed
A new global assessment of purchasing agreements for COVID-19 vaccines reveals that high-income countries, as well as a few middle-income countries flush with manufacturing capacity, have already purchased nearly 3.8 billion doses, with options for another five billion.

Meanwhile, the study found that only enough doses to cover 250 million people have been confirmed as purchased thus far by COVAX, a global effort involving both wealthy and poor countries that has promised equal access to COVID-19 vaccines globally, regardless of income levels.
Taylor and her colleagues conducted their assessment by reviewing available evidence from public sources through October 8, 2020, combined with interviews with global and regional vaccine experts, as well as ministry of health officials in select countries. The analysis looked at advance market commitments (AMCs) for COVID-19 vaccines in order to better understand their overall volume and ultimate destination.
Taylor said the vaccine outlook for low-income countries could be even bleaker when considering that the vast majority of low-income countries need vaccines that do not require extreme cold storage. That means only certain candidates in development will be suitable.
Taylor noted that other challenges that disproportionately impact low-income countries include the need to have supplies like syringes shipped and available in time for the arrival of vaccines. Also, she said that while there have been major advances in developing a better infrastructure in low-income countries for childhood vaccinations, COVID-19 will require vaccination campaigns targeting adults and especially older adults.
As we head into the fall, we know that there is a potential for an increase in infections, in part due to increased waning of immunity from vaccines and prior infection. Additionally, as the weather gets colder and people spend more time indoors, contagious viruses like COVID-19 can spread more easily. And, as we saw last fall with the emergence of Omicron, we must continue to stay prepared for the possibility of a potential new variant of concern.
1. Getting Americans the best available protection through free and easy access to new, updated COVID-19 vaccines.Following actions last week by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC), we are launching a new, updated COVID-19 vaccine this week. The new vaccines provide the strongest available protection from the Omicron strain of the COVID virus, which did not exist when the original vaccine was developed. As the virus continues to change, we will now be able to update our vaccines annually to target the dominant variant. Everyone age 12 years and older is eligible for these updated vaccines at least two months after their primary series or their most recent booster. Given the potential for cases to increase in the fall and winter, it is critical that Americans get a new, updated COVID-19 vaccine to stay protected. The Administration is launching a comprehensive effort to make sure that these vaccines are free, widely available, and easy to access for all Americans.
The Phase I/II data for our coronavirus vaccine shows that the vaccine did not lead to any unexpected reactions and had a similar safety profile to previous vaccines of this type. The immune responses observed following vaccination are in line with what previous animal studies have shown are associated with protection against the SARS-CoV-2 virus, although we must continue with our rigorous clinical trial programme to confirm this in humans
The chief adviser of Operation Warp Speed, the national program set by the government to accelerate the development and distribution of coronavirus vaccines, revealed he doesn't know what President Donald Trump's upcoming executive order on COVID-19 vaccines entails.
When Stephanopoulos said, "You don't know? But you're the chief science adviser for Operation Warp Speed," Slaoui replied, "Our work is, you know, rolling. We have plans we feel that we can deliver the vaccines as needed. So I don't know exactly what this order is about."
Earlier in the interview, Slaoui noted: "We are comfortable that we will be getting the vaccines to the people who need them as soon as possible. Because there are vaccine doses from Moderna, there are vaccine doses from Pfizer. We will work with Pfizer to try and increase capacity and have those vaccines available.
"We have tens of millions of doses from those vaccines participating to the volume of vaccines we need to immunize the U.S. population as we promised all of it by the middle of the year 2021 and that's still on track," Slaoui told Stephanopoulos.
Edible vaccines activate both mucosal and systemic immunity, as they come in contact with the digestive tract lining which is not possible with subunit vaccines which provide poor mucosal response. This dual effect of edible vaccines provides first-line defense against pathogens invading through mucosa, such as Mycobacterium tuberculosis and agents causing diarrhea, pneumonia, STDs, HIV, etc.
As a recent progress, the first human clinical trials for plant-based vaccine have been performed; it brings many challenges like optimization of expression levels, stabilization during post harvest storage, etc. Long-term reactions to edible vaccines are yet to be determined. Possible delayed reactions not yet discovered may be the point of consideration. In addition to that, edible vaccines can be further improved for their oral immunogenicity by the use of specific adjuvant which can be applied either as a fusion to the candidate gene or as an independent gene. Some of the diseases to which edible vaccines have shown promising application may be elaborated in the veterinary as well as human spectrum. These studies conclude plant-derived vaccines as a new hope and promise for more immunogenic, more effective, and less expensive vaccination strategies against both respiratory as well as intestinal mucosal pathogens.
Going forward, the single-dose vaccine will only be available to people 18 and older who cannot take one of the other available vaccines for medical reasons, or who simply will not agree to be vaccinated with one of the messenger RNA vaccines made by Moderna and by Pfizer and its partner BioNTech.
The National Vaccine Storage Guidelines: Strive for 5 provide best practice guidelines for storing vaccines and managing the cold chain. Resources are available from the National Vaccine Storage resource collection. The new guidelines were released in June 2019. Refer to the summary of key changes.
The NSW Health Vaccine Storage and Cold Chain Management Policy provides mandatory requirements for the storage and management of vaccines in NSW public facilities. The policy directive includes a Vaccine Refrigerator Protocol for public facilities.
All vaccines must be stored within the recommended temperature range of +2C to +8C at all times. Maintaining the cold chain is important to ensure that effective and potent vaccines are administered to patients.
The spat revolves around the EU's deal with AstraZeneca, which recently informed the bloc it would not be able to supply the number of vaccines the EU had hoped for by the end of March. EU leaders are furious that the company appears to be fulfilling its deliveries for the U.K. market and not theirs.
Peter Bone, a Conservative British lawmaker, said EU leaders were "bullies" for inspecting the Belgian plant. In an interview with talkRADIO on Friday, he accused them of "trying to cover up for their own failures" and reversed the EU's accusation, saying Brussels was trying to divert U.K.-made vaccines to its own people.
But the EU's contract with AstraZeneca -- which Brussels published on Friday -- states that doses for the bloc could indeed come from a supply chain that includes UK-based plants. Equally, the U.K. is receiving doses from Europe as well -- a person familiar with the matter said that the U.K. is still receiving small numbers of vaccines made in European plants, and that its initial doses had come from Europe too.
"The manufacturing of vaccines is extremely complicated, it's not like doing an orange juice, it's extremely complicated and the teams that are manufacturing those products have to be trained and they have to master the process," he said, adding that the U.K. had a head start in addressing inevitable teething issues.
There is a lot riding politically on a successful vaccine program. U.K. Prime Minister Boris Johnson's government has been lambasted by much of the media and public for a shambolic Covid-19 response. But the country's leadership in developing, approving and now distributing vaccines is being widely celebrated. It's a political win Johnson sorely needs.
Terje Andreas Eikemo, director of the Centre for Global Health Inequalities Research at the Norwegian University of Science and Technology, said that vaccines should be shared among the world's most vulnerable people first, regardless of where they live.
There is a huge sense of nervousness in much of the developing world: people there are watching some of the richest nations scramble for doses after buying up huge numbers of vaccines in advanced purchase agreements before they were even proven effective.
"Some countries have even gone beyond and acquired up to four times what their population needs, and that was aimed at hoarding these vaccines. And now this is being done to the exclusion of other countries in the world that most need this," he said.
But there appears to be little hope of that actually happening. Even the WHO -- whose chief in September said initial vaccines should reach "some people in all countries, rather than all people in some countries" -- appears to have lost hope of a truly collaborative response.
The group charged with making the decisions about vaccines has been right about 80 percent of the time, said Dr. Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases, and the new findings should lead to an even higher success rate. 041b061a72
