evidence: From autumn 2024 onwards, COVID-19 vaccination is recommended in autumn/winter for persons at an increased risk of developing a severe case of the illness (including pregnant persons). COVID-19 vaccination is not recommended for any other persons. Almost everyone in Switzerland has come into contact with the coronavirus by now, meaning that their immune system has already had to respond to the virus. The coronavirus variants currently circulating also tend to cause only mild cases of COVID-19 among persons without any risk factors. As a result of the greater contacts that people are likely to have in enclosed spaces, the coronavirus may well spread more again in the coming winter season. And this in turn may increase the likelihood of contracting COVID-19.
