Is catching Covid now better than more vaccine?

There are marked differences in your immune system after a natural infection with coronavirus and after vaccination.

Which is better?

Even asking the question bordered on heresy a year ago, when catching Covid for the first time could be deadly, especially for the elderly or people already in poor health.

Now, we're no longer starting with zero immunity as the overwhelming majority of people have either been vaccinated or have already caught the virus.

It is now a serious question that has implications for whether children should ever be vaccinated. And whether we use the virus or booster shots to top up immunity in adults. Both have become contentious issues.

"We could be digging ourselves into a hole, for a very long time, where we think we can only keep Covid away by boosting every year," Prof Eleanor Riley, an immunologist from the University of Edinburgh, told me.

Prof Adam Finn, a government vaccine adviser, said over-vaccinating people, when other parts of the world had none, was "a bit insane, it's not just inequitable, it's stupid"
