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 %?
