COVID-19 Weekly Newsletter: New Vaccines, Streamlined Shipment Coordination

Addressing new variants, coordinating vaccine shipments and the continued progress of a third vaccine highlighted this week in the COVID-19 response.

Vaccine Manufacturers Tackle New Variant

Manufacturers of COVID-19 vaccines currently available in the US look to a third dose to provide additional protection against the virus and its variants as both have been found to generate a weaker immune response to the South Africa variant. One such newly developed COVID-19 vaccine will begin human trials and another is being given to existing phase I clinical trial participants a third dose of the current vaccine to see if it can help. Earlier this week, the Food & Drug Administration (FDA) released guidance suggesting manufacturers could skip massive phase 3 trials for modified coronavirus vaccines targeting certain strains. 

Vaccine Shipment Coordination

Governors earlier this week were told by White House Coronavirus Coordinator Jeff Zentis that they can expect to know how many vaccine shipments they will be getting months ahead of time — rather than on a week-to-week basis. This will hopefully help states to plan vaccination distribution and set appointments at clinics appropriately. In the past month, vaccine weekly shipments have ramped up from 8.6 million a week to 14.5 million. This new forecasting approach from the administration comes just a week after governors raised concerns that the new federal strategy to directly send vaccines to pharmacies will exclude their input and cause redundancy and inefficiencies. States hope this forecasting will help in bringing them clarity.

Third Vaccine Approaches EUA

A single-dose vaccine is on track for FDA emergency use authorization (EUA). If approved, it will be the third vaccine to be circulated in the country. Today, FDA's Vaccines and Related Biological Products Advisory Committee’s (VRBPAC) will decide to recommend FDA to issue an EUA for the vaccine.

Study Explores Vitamin D3 Benefits

Vitamin D3, which has been suggested to positively impact immunity, has been a focus as a potential therapeutic intervention for COVID-19. A recent study found that single high doses of Vitamin D3 did not significantly reduce length of hospital stay for patients with moderate to severe COVID-19. The randomized, placebo-controlled study included 240 hospitalized individuals. Some limitations of the study include the relatively small number of patients and thus may lack the statistical power to exclude small, clinically meaningful differences among the study groups; and co-morbidities and consequent intake of other medications among the patients.

Pigmentation Differences Creating Disparities in Pulse Oximeter Accuracy?

The FDA recently released a safety communication explaining that pulse oximeters may be inaccurate when applied to people with dark skin pigmentation. The announcement references the December 2020 communication from researchers who compared the accuracy of pulse oximeters on two large cohorts of Black and white patients and found that Black patients had nearly three times the frequency of lowered arterial oxygen saturation not detected by pulse oximetry compared to white patients. The paper notes the criticality of understanding and correcting racial bias in this and other medical technologies.

COVID-19 Relief Legislation Update

The United States House of Representatives is expected to pass President Biden’s requested $1.9 trillion COVID-19 relief legislative package Friday night along party lines. Despite the Senate parliamentarian’s determination late Thursday that the inclusion of a mandated $15 federal minimum wage violates budget rules dictating the legislative process, House Democrats are leaving the policy in the package. That policy will likely be stripped in the Senate, requiring the package to be sent back to the House for passage at least one more time.
