The vaccine for 'flu is far from perfect. It has to be modified twice a year due to mutations and only gives protection up to 60%.
Not sure on your figures, but you are certainly correct that it it is far from perfect. We are nowhere near the same standard with regards to the Coronavirus.
New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes
According to the CDC, the flu vaccine reduces the odds of getting the flu by about 60%. But that number varies from year to year and among different groups of people.
'Flu shot this year may not be as effective as usual.
There's more bad news about the flu: The main strain of flu that's circulating right now doesn't exactly match what's in this year's flu shot, according to a new report.
However, the strain in the vaccine may still be close enough to offer some protection, officials said.
There are several different vaccines that offer protection against 3 'flu viruses or 4 viruses. Some of the vaccines are age related and not recommended for certain age groups.
The reason that the vaccine is rarely an exact match is the developers have to 'guess' in advance of how the virus will mutate in the near future.
Vaccines in general are a form of the virus that is actually dead or weakened. The idea is the shot will give your immune system a jolt to produce antibodies that will help to protect in the limited future.
It is possible, according to some reports, that WuFlu will develop into another version of seasonal 'flu adding to the known 'flu viruses from 4 to 5.
