The continuing politicization of COVID-19 vaccines is undermining medical science and the international response to the pandemic. “Vaccine nationalism is very troubling,” Jeremy Levin, chair of the Biotechnology Innovation Organization’s (BIO) executive committee, told BioWorld.
CAJICA, Colombia – Countries in Latin America have joined those in Europe expressing mixed reactions about continuing their vaccination plans with the AZD-1222 SARS-CoV-2 vaccine developed by Astrazeneca plc and the University of Oxford, following reports of alleged adverse events.
LONDON – Astrazeneca plc promised to publish the primary analysis of the phase III U.S. trial of its COVID-19 vaccine by the morning of March 25, after chastisement from the data safety monitoring board (DSMB) for using “outdated” information in the interim results published on March 22.
PERTH, Australia – Australia’s Therapeutic Goods Administration (TGA) has approved Australian manufacture of Astrazeneca plc’s COVID-19 vaccine (ChAdOx1-S), which is being manufactured by CSL Ltd.
Vaccines now in clinical trials can raise broad-spectrum antibodies against more than one form of hemagglutinin and provide protection against the flu strains that have been most troublesome from a public health perspective.
LONDON – Positive interim data from the U.S. trial of Astrazeneca plc’s COVID-19 vaccine have added yet more evidence it is effective in older adults and quelled concerns about serious thrombotic events that led countries in Europe to pause use of the vaccine earlier this month. Overall, the vaccine showed 79% efficacy in preventing symptomatic COVID-19, and was 100% effective in preventing serious disease and hospitalization. The effect was comparable across different ethnicities and age groups, with 80% efficacy in participants over 65 years of age. The analysis is based on 141 cases of COVID-19 infection.
CAJICA, Colombia – Countries in Latin America have joined those in Europe expressing mixed reactions about continuing their vaccination plans with the AZD-1222 SARS-CoV-2 vaccine developed by Astrazeneca plc and the University of Oxford, following reports of alleged adverse events.
A U.S. Senate committee met March 18 to review the federal government’s response to the COVID-19 pandemic, during which former FDA commissioner David Kessler said the Trump administration’s vaccine contracts were expensive, but effective in ensuring a robust supply. Nonetheless, Sen. Chris Murphy (D-Conn.) said one vaccine manufacturer had recently voiced an interest in charging more on a per-dose basis for its vaccine, and suggested that the cost of booster shots should perhaps be examined anew by the Biden administration.
LONDON – Astrazeneca plc’s COVID-19 vaccine is safe and effective and the benefits well outweigh any risks, according to a review carried out by the EMA, following reports of blood clots in people who received the vaccine.
After working 24/7 to develop a COVID-19 vaccine in a historic timeframe and scale up manufacturing at an unprecedented rate, some vaccine manufacturers are now facing what appears to be a concerted Russian misinformation campaign akin to those used in the last two U.S. presidential campaigns.
