I can see how you'd get that impression if you followed the news through mainstream media and government spokespersons who stoked fear and uncertainty to push their recommendations, but I paid close attention to research and data, and there were countless instances of health authorities peddling obvious falsehoods, some of which I've already mentioned.
I traveled freely internationally throughout 2020 before a blanket ban was implemented to force people to get vaccinated. Of course, by that time, the virus was circulating everywhere, so it already made little sense, but it's even worse when you consider that long-distance travel was not a significant vector for viral spread (at that stage). If I recall correctly, the Canadian government admitted in court that their own travel ban had no scientific basis. In the US, the health authorities issued recommendations based on weak or absent data and then refused to withdraw them until the amount of data disproving those recommendations became overwhelming. That's a double standard and can hardly be justified with "uncertainty".
I'll add that many people pointed out the inconsistencies between government recommendations/policies and the available evidence at the time, and in response, they were fired, hidden or banned from social media, attacked, and demonized. Now history is being rewritten, but "in hindsight" there were plenty of warnings at all stages of this crisis.
