What [covid jabs] won’t do, according to an increasing body of evidence, is prevent you from being a carrier and thus a danger to others. This somewhat defeats the whole point – and is certainly the only reason international travel has resumed of late.
Last week, in news that hasn’t got nearly enough airtime, Public Health England said in a statement: “Some initial findings […] indicate that levels of virus in those who become infected with Delta having already been vaccinated may be similar to levels found in unvaccinated people. This may have implications for people’s infectiousness, whether they have been vaccinated or not.”
The travel and tourism industry has been one of the sectors hit hardest by the pandemic, with lockdowns and travel restrictions all but shutting business at times.
