Actually 60-80% effective based on 2018 numbers. Because they can't predict the variants the flu will mutate into this year. One year they'll fuck up and have a really shitty batch of completely worthless trash and the other year it's a near perfect vaccines.
Flu is a special case. Guess what though. The measles vaccines is way better and nearly wiped out the disease until people stopped getting it.
Oh and before you bring up polio vaccines... using crappy attenuated oral vaccines because third world tribes fear needles and Bill Gates is evil doesn't mean polio wasn't eradicated in the West thanks to the superior inactivated injection polio vaccine by dr Salk.
Which he gave away instead of charging $1000 a pop. And the 1st year that pharma was involved a defective batch was distributed in California infecting 1000s, crippling hundreds, and killing 10 out of the 200k injections.
How does one prove a negative? That not getting the flu is proof that a vaccine is effective. Reminder that according to the CDC, efficacy rate was as low as 19% for 2014-2015.
Most studies that use placebo as a base measurement have better % efficacy with placebo.
Same principal the China virus mitigation is based on. Healthy people have to stay under house-arrest to prevent people from dying. Another negative impossible to prove.
Good damn question. How do we know that those who dont contract the flu would have contracted it if they didnt get the shot?
About a third of my patients who tested positive for flu had the shot. What proof do we have that it ever works? If we had 90% immunity then I might buy it but 12 %?
