Thanks, the comment implied the August 13 use date (but there is no explanation of the time lag between Tokyo and Osaka), but it’s not explicit. For all I know, the Japan AMA could have recommended ivermectin use on August 13th, but no one listened.
Hopefully they did adopt its use, and the future graphs will be clearer (e.g., including a line where ivermectin use was adopted on a wide scale).
Don’t you think it might take a little time to shift gears from the vaccine to Ivermectin? They probably had to go through the process of appropriating it first. I think they did a fantastic job in a short period of time.
