HONG KONG – Following a wave of concern about the efficacy of two COVID-19 vaccine candidates developed by China National Pharmaceutical Group (Sinopharm), interim analysis of an ongoing phase III trial, published May 26 in the Journal of the American Medical Association, has shown that adults receiving at least one dose of either of the company’s two inactivated SARS-CoV-2 vaccines had significantly reduced the risk of symptomatic COVID-19.
As infections and deaths continue to surge in some countries so does the demand for unfettered access to the technologies behind COVID-19 vaccines and other medical products. In seeking that access, several countries are stressing the need to develop their own manufacturing capacity as they look beyond the current pandemic.
Seychelles has seen rising numbers of COVID-19 cases despite 61% of its population being fully vaccinated as of May 8, calling into question the effectiveness of the COVID-19 vaccines used by the island nation.

As COVID-19 deaths across the globe top 3 million, with more than 1 million in Europe alone, the global demand is increasing for mRNA vaccines, even as sponsors of adenovirus vaccines push back against ongoing safety concerns. Last week, the World Health Organization’s (WHO) Regional Office for Europe reported that the confirmed COVID-19 death toll for the region had surpassed 1 million, with 1.6 million new cases being reported every week. More than 171 million doses of COVID-19 vaccines have been administered in the region, translating to nearly 13% of the European population receiving one dose and close to 6% completing both doses of the vaccines.
PERTH, Australia – The Australian government is recommending that Australians under 50 take the Pfizer Inc. COVID-19 vaccine due to the risk of rare blood clots associated with Astrazeneca plc’s COVID-19 vaccine (ChAdOx1-S).

If these top-line phase III results were a grade card for 12- to 15-year-olds, they would be on the honor roll: The Pfizer Inc.-Biontech SE COVID-19 vaccine is 100% effective for the age group and produced robust antibody responses. The new results play out against a backdrop of increased production and big revenue estimates.
