On Monday, Pfizer said it has started a pilot Covid-19 vaccination program in four US states to help improve the delivery and deployment plan for the candidate vaccine.
The US drugmaker said it chose Rhode Island, Texas, New Mexico and Tennessee for the program due to differences in overall size, diversity of populations and immunization infrastructure, as well as the states’ need to reach individuals in diverse urban and rural areas. Settings.
“The four states included in this pilot program will not receive vaccine doses earlier than other countries under this pilot program, and they will not receive any differential considerations,” Pfizer said in a statement.
Last Monday, Pfizer released preliminary data on its vaccine, which it developed with German partner BioNTech SE, which has shown to be 90% more effective.
Earlier Monday, rival Moderna Inc said its experimental vaccine is 94.5% effective in preventing Covid-19 based on tentative data from a late-stage trial, raising hopes that vaccines against the disease may be ready for use soon.
The Pfizer and Moderna vaccines use a new technology called synthetic messenger RNA to activate the immune system against the virus.
Experts have raised concerns about distribution challenges associated with the Pfizer vaccine due to specialized storage requirements.
