Tamiflu is the Roche brandname for Oseltamivir, which is stockpiled by the government. Oseltamivir is made from Chinese Star Anise, taking 90% of global crop. Chinese Star Anise which can be bought in health food stores and Chinese supermarkets. I've heard that a cup of Chinese Star Anise tea is just as effective as Tamiflu. That may or may not be true but it does you no harm and it should relieve any anxiety and hypochondria. During the initial avian flu scare Chinese Star Anise disappeared from the shops pretty quickly. It's something that activist healthfood co-ops should consider getting a stock in, if only to meet the extra demand at times like this.
Any activist who visits a Chinese supermarket should also buy themselves a durian fruit, the king of fruits. Although it is delicious it isn't effective against flu but you will soon be able to figure out why it is useful.
