When Bob Briley retired as a firefighter and paramedic in West Palm Beach, FL to work with the Federal Emergency Management Agency (FEMA), he was accustomed to a 24/7 schedule with a certain level of unpredictability. He also knew that his poised under pressure temperament was an asset to his success. When he brought that skill set to CDC in 2009 as a Deployment Briefing Coordinator during H1N1, he may have solidified his path as one who works in the places that never sleep.

Learn about hospital surveillance (rates) and how that information helps find who is most at risk for severe illness and death, including important demographic information

The Moderna COVID-19 vaccine is an mRNA vaccine that requires 2 shots, 28 days apart. Learn about safety data, efficacy, and clinical trial demographics.

COVID-19 vaccines are safe and effective. Millions of people in the United States have received COVID-19 vaccines, and these vaccines will undergo the most intensive safety monitoring in U.S. history. CDC recommends you get a COVID-19 vaccine as soon as you are eligible. Adverse events described on this page have been reported to the Vaccine Adverse Event Reporting System (VAERS).

On 8-10 November 2021, Dr Naveen Rao, Senior Vice President, Health and other senior representatives from The Rockefeller Foundation joined World Health Organization (WHO) representatives to review the strategic directions of collaboration between the two Organizations. Notably they discussed support for the WHO Health Emergencies Programme and the Science Division, including the WHO Hub on for Pandemic and Epidemic Intelligence, genomic surveillance, infodemiology, vaccine equity and demand generation and WHO’s ongoing work with philanthropic organizations.

”The Rockefeller Foundation and WHO have worked together to address global health challenges since WHO was first established,” said Ms Jane Ellison, Executive Director, External Relations and Governance. ”The support of the Foundation has been – and will continue to be - fundamental, helping WHO to make major advances in providing equitable health outcomes for all.”

The Rockefeller Foundation’s collaboration with WHO dates back to when the WHO constitution was first created. Over the past two decades, The Rockefeller Foundation has continued to be a key collaborator, providing over US$ 25.3 million in support to WHO programmes.

Recent collaboration has focused on digital health building capacity in data and innovation to protect and promote health and well-being. Throughout the COVID-19 pandemic, the two Organizations worked together towards the goal of maintaining essential health services everywhere, expanding virus testing capacity, strengthening and accelerating the digitalization of WHO guidelines, and advancing approaches to using digital products to end the current pandemic and prevent future ones. The Rockefeller Foundation and WHO currently co-lead the Access to COVID-19 Tools Accelerator (ACT-A) Genomic Surveillance Working Group.

“The Rockefeller Foundation recognizes WHO’s unique and vital role in safeguarding global health and well-being,” said Dr Naveen Rao, Senior Vice President, Health, The Rockefeller Foundation. “We remain steadfast in our commitment to support WHO to be a strong and efficient Organization.”

The overall objectives of the strategic dialogue were for the two Organizations to gain a better understanding of each other’s current work and priorities, and explore expanded areas for collaboration based on a more deliberate and forward-looking relationship leveraging the comparative advantages of each Organization to maximize public health impact.

Building on lessons learned from our collective experience with dose donations over the past several months, the African Vaccine Acquisition Trust (AVAT), the Africa Centres for Disease Control and Prevention (Africa CDC) and COVAX wish to draw the attention of the international community to the situation of donations of COVID-19 vaccines to Africa, and other COVAX participating economies, particularly those supported by the Gavi COVAX Advance Market Commitment (AMC).

AVAT and COVAX complement each other’s efforts to support African countries to meet their immunisation targets, recognising the global goal of immunising 70% of the African population. Dose donations have been an important source of supply while other sources are stepping up, but the quality of donations needs to improve.

AVAT and COVAX are focused on accelerating access to and rollout of COVID-19 vaccines in Africa. Together we are rapidly expanding supply to the continent, and providing countries with the support to be able to utilise the doses they receive. To date, over 90 million donated doses have been delivered to the continent via COVAX and AVAT and millions more via bilateral arrangements.

However, the majority of the donations to-date have been ad hoc, provided with little notice and short shelf lives. This has made it extremely challenging for countries to plan vaccination campaigns and increase absorptive capacity. To achieve higher coverage rates across the continent, and for donations to be a sustainable source of supply that can complement supply from AVAT and COVAX purchase agreements, this trend must change.

Countries need predictable and reliable supply. Having to plan at short notice and ensure uptake of doses with short shelf lives exponentially magnifies the logistical burden on health systems that are already stretched. Furthermore, ad hoc supply of this kind utilises capacity – human resources, infrastructure, cold chain – that could be directed towards long-term successful and sustainable rollout. It also dramatically increases the risks of expiry once doses with already short shelf-lives arrive in country, which may have long-term repercussions for vaccine confidence.

Donations to COVAX, AVAT, and African countries must be made in a way that allows countries to effectively mobilise domestic resources in support of rollout and enables long-term planning to increase coverage rates. We call on the international community, particularly donors and manufacturers, to commit to this effort by adhering to the following standards, beginning from 1 January 2022:

• Quantity and predictability: Donor countries should endeavour to release donated doses in large volumes and in a predictable manner, to reduce transaction costs. We acknowledge and welcome the progress being made in this area, but note that the frequency of exceptions to this approach places increased burden on countries, AVAT and COVAX.
• Earmarking: These doses should be unearmarked for greatest effectiveness and to support long-term planning. Earmarking makes it far more difficult to allocate supply based on equity, and to account for specific countries’ absorptive capacity. It also increases the risk that short shelf-life donations utilise countries’ cold chain capacity – capacity that is then unavailable when AVAT or COVAX are allocating doses with longer shelf lives under their own purchase agreements.
• Shelf life: As a default, donated doses should have a minimum of 10 weeks shelf life when they arrive in-country, with limited exceptions only where recipient countries indicate willingness and ability to absorb doses with shorter shelf lives.
• Early notice: Recipient countries need to be made aware of the availability of donated doses not less than 4 weeks before their tentative arrival in-country.
• Response times: All stakeholders should seek to provide rapid response on essential information. This includes essential supply information from manufacturers (total volumes available for donation, shelf life, manufacturing site), confirmation of donation offer from donors, and acceptance/refusal of allocations from countries. Last minute information can further complicate processes, increasing transaction costs, reducing available shelf life and increasing risk of expiry.
• Ancillaries: The majority of donations to-date do not include the necessary vaccination supplies such as syringes and diluent, nor do they cover freight costs -  meaning these have to be sourced separately – leading to additional costs, complexity and delay. Donated doses should be accompanied with all essential ancillaries to ensure rapid allocation and absorption.

AVAT, Africa CDC and COVAX remain committed to collaborate with donor countries, vaccine manufacturers and partners on ensuring these standards are upheld, as we continue to work together towards achieving Africa’s vaccination goals.
