Would be hard to keep quiet tho if folk were rolling up at hospital having been vaccinated 5 weeks earlier.You might have expected them to shout that from the rooftops.
Folk becoming under weather and staying at home must be happening, I can vouch for that but if folk were still ending up in ICU the families would be straight to papers, social media etc. You can't keep anything quiet these days.. Personally, don't think it's happening. Besides would NHS still be so keen rolling out vaccine if essentially it wasn't working.. Becomes a pointless exercise. Can't see it myself.
