Here in the Netherlands they did a crude antibodies test by testing blood plasma donated by a number of people. It's not really conclusive, but they found that now about 3% of the people have generated antibodies which means about 3% of the population has had some kind of exposure to the virus. Out of a population of 17.5M that means that after all this time only 0.5M have some kind of defence against the virus. It's also the question in what capacity their antibodies will be effective. In any case, this is long ways from establishing group immunity, the downside of lockdowns. Maybe the Swedish approach isn't so bad.
