COVAX updates delivery of COVID vaccines delays from Serum Institute of India (SII) and AstraZeneca

COVAX and the Government of India remain in discussions to ensure some supplies are completed during March and April.

March 27, Geneva: Deliveries of COVID-19 vaccines produced by the Serum Institute of India (SII) to lower-income economies participating in the COVAX Facility will face delays during March and April as the Government of India battles a new wave of COVID-19 infections.

According to the agreement between Gavi and the Serum Institute of India (SII), which included funding to support an increase in manufacturing capacity, SII is contracted to provide COVAX with the SII-licensed and manufactured AstraZeneca (AZ)-Oxford vaccine (known as COVISHIELD) to 64 lower-income economies participating in the Gavi COVAX AMC (including India), alongside its commitments to the Government of India.

To date, COVAX has been supplied with 28 million COVISHIELD doses and was expecting an additional 40 million doses to be available in March, and up to 50 million doses in April.

COVAX has notified all affected economies of potential delays. SII has pledged that, alongside supplying India, it will prioritize the COVAX multilateral solution for equitable distribution.

Participating economies have also received WHO guidance on optimizing the national deployment doses of the AstraZeneca-Oxford vaccine in a constrained supply environment.

Separately, the COVAX Facility has informed participants allocated AstraZeneca-manufactured doses of the AstraZeneca-Oxford vaccine that some of the first deliveries due in March are now set to take place in April.

In this early phase of COVID-19 vaccine roll-out, vaccine manufacturers require time to scale and optimize their production processes. AstraZeneca, which uses a novel supply chain network with sites across multiple continents, is working to enable initial supply to 82 countries through COVAX in the coming weeks.

COVAX retains its objective of supplying initial doses of vaccines to all participating economies in the first half of the year before ramping up significantly in the second half of 2021. To date, COVAX has shipped vaccines to over 50 countries and economies.
