I don't suppose too many of us have enough knowledge of what virus's are, how vacines work, what precautions are essential / which are worthless etc to be able to cut through the bullsh*t on our own. So we have to choose who to believe, and often there's just enough 'pseudotruth' in some of the stories to cause you to doubt the official line, especially if you're suspicious of government and you're being told it by someone you trust.

Bill Gates microchips for example. No, there's no microchips being implanted, and no, the vaccine isn't going to change your DNA and turn you into a zombie (or whatever it's supposed to do) but two of the vaccines do inject RNA (DNA, RNA, potato, potaato) which goes into some of your cells and highjacks them to produce foreign proteins. If your political senses are more finely tuned than your virology ones that doesn't need much of a twist to become the message 'the government wants you to inject stuff into your body that'll take it over'. As nobody knows what proteins or RNA are microchips become a stand-in.

If you think that's patronisingly simplistic I know a health professional - a multi decade nurse - working in a large hospital who has refused to be vaccinated because 'it'll make me infertile'. She's in her 60's! Despite working with the stuff all day long her personal beliefs, sourced from her community, have overridden her professional knowledge. If she's taken in by it all what hope do many of the rest of us have.

Part of the problem with 'social passports' is that those most likely to need them will be the last to get them. If there's an unfulfilled need then 'alternative' sources will fill the void. Introducing them on a Monday to have the market flooded with fake ones by Friday isn't going to do much for disease control measures. My guess is a combination of the elections in May (don't upset the electorate just before they have to vote you back in) and how to produce something that won't be counterfeited (for a while anyway) is what's being kicked around in smoke filled rooms at present.
