@KonstantinKisin @BretWeinstein @JesslovesMJK why would it be any different for covid than for influenza? it's called _healthy_ vaccinee bias for a reason https://t.co/EWExaCdbgq
@AlexBerenson Both effects exist. What you describe is part of the "healthy vaccinee bias". The other effect is the "confounding by indication" which occurs when people with underlying chronic diseases are more likely to be vaccinated than healthy people.
@DavidC_Hatfield @AlexBerenson Please show me where this has been documented? Healthy vaccinee bias has been btw - and it has been known for a while https://t.co/4bhWkt0s13.
@eckels_sam @AlexBerenson Oh you mean the effect that has been known to confound vaccine studies forever? Plus how long were 'only vulnerable people' eligible until the jab became a passport to normal life? https://t.co/4bhWkt0s13.

@KalmiaLatifolia @USMortality You know it's true, but setting that aside, there is still the healthy vaccinee effect. "resulting estimates are still prone to healthy vaccinee bias, at least as long as unspecific outcomes like all-cause mortality are used.
