CAJICA, Colombia – Brazil’s health care surveillance agency, Anvisa, granted the first two emergency approvals for COVID-19 vaccines on Sunday, Jan. 17, giving the green light to Sinovac Biotech Ltd.’s Coronavac and to Covishield, developed by Astrazeneca plc and the University of Oxford.
Moncef Slaoui, chief advisor to Operation Warp Speed, the public-private partnership to hurry along a vaccine for COVID-19, cited tough going in the early days of development, as researchers met “a real challenge to engage the population.” During a panel discussion at the virtual 39th J.P. Morgan Healthcare Conference, he pointed to “a double-edged sword, to talk about what a vaccine can do, when we don’t know – and then once you know, you’re going to have to change your message.”
CAJICA, Colombia – Authorities in Brazil released new efficacy data for Sinovac Biotech Ltd.'s COVID-19 vaccine Coronavac that surprised on the downside, suggesting the vaccine could be much less effective than initially indicated for preventing symptomatic infections.
CAJICA, Colombia – A phase III trial for an HIV vaccine developed Janssen Vaccines & Prevention BV is finally moving forward in Latin America and elsewhere in the world after a delay of more than a year caused by slow regulatory progress and worsened by a string of COVID-19 lockdowns.
CAJICA, Colombia – Brazil's Butantan Institute and the government of the state of Sao Paulo released efficacy results on Jan. 7 for Coronavac, developed by China’s Sinovac Biotech Ltd., that suggest the COVID-19 vaccine is more than 78% effective.
DUBLIN – Curevac AG has entered a global alliance with Bayer AG to accelerate its efforts to bring a third, desperately needed mRNA-based COVID-19 vaccine to market. The vaccine in question, CVnCoV, began a pivotal phase IIb/III trial on Dec. 14.
LONDON – The EMA has recommended approval of Moderna Inc.’s COVID-19 vaccine, becoming the fourth western regulator to do so, after Israel approved the product on Jan. 5 and the FDA and Health Canada in December.
LONDON – Controversy has erupted over COVID-19 vaccines dosing after the U.K. said it is to prioritize giving as many people as possible a single dose of the two currently approved products, rather than two doses three or four weeks apart, as scheduled on their labels. The move prompted a sharp rebuke from FDA Commissioner Stephen Hahn and Peter Marks, director of FDA’s Center for Biologics Evaluation, who said any such change “is not rooted in the science.”
Relief spread across the world in December when the first two mRNA COVID-19 vaccines received emergency use approvals, although that deep sigh was short-lived as a highly-transmissible SARS-COV-2 mutation began to make its rounds, highlighting the need for continued research to strengthen the arsenal.
NEW DELHI – The Drugs Controller General of India (DCGI) granted its first emergency conditional approvals Jan. 3 for a pair of COVID-19 vaccines, including Covishield, developed abroad by Astrazeneca plc and Oxford University and manufactured by the Pune-based Serum Institute of India (SII). The DCGI also approved Covaxin, which was developed locally by Hyderabad-based Bharat Biotech International Ltd. in collaboration with the Indian Council of Medical Research, and is still in phase III trials.
