The "no evidence" mantra we've seen to quash unpalatable truths from a lab-leak origin to vaccine side-effects to vaccine resistant variants is still alive and well:

BBC: The Department of Health and Social Care: There is no firm evidence yet to show this variant (Indian) has any greater impact on severity of disease or evades the vaccine.

If there's no evidence, why are all the vaccine companies scrambling to make so called "booster" shots? Why would you waste your time and money if the current vaccines work fine against variants?
