FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) chooses the flu vaccine viruses for the United States. Which strains of the flu that go into the vaccine are typically determined in March, shortly after production begins in time for the fall/winter season. There is some educated guessing into which strains are predicted to circulate through the community later that same year, so there is a risk that some years the flu vaccine might not be as effective as they hoped. The flu shot is NOT a guarantee that you won't get the flu but if you contract a strain of the flu that was in the shot it can greatly lessen the severity of the illness.
As of 15 hours ago the CDC is saying that the 2019/2020 flu season has yet to peak. You have to wait until the peak before you can determine the vaccines effectiveness.
U.S. flu deaths hit 14,000, haven’t peaked yet, CDC says
Check out the current numbers for Flu 14,000 deaths to 26 million infections in the US. 14,000/26,000,000 = 5.38 or .05% death rate. Still allegedly higher than Covid-19 at .02% death rate.
This is absurd. They sent home the very few hospital staff that came into contact with the woman but they are just assuming the Uber driver couldn't have contracted it. WTF?! They were both confined in a tiny space together for what was likely longer than 5 minutes and they let the driver off. They did suspend his Uber account though, but still.
