ZURICH, Jan 5 — Everyone in Switzerland who wants to be vaccinated against Covid-19 should be able to get a shot by summer, a Swiss health official said today, as the nation anticipates imminent approval of a second vaccine, this one from Moderna.

With 233,000 doses delivered by Pfizer and BioNTech , so far, the country is expecting vaccine deliveries to hit 500,000 in January and one million in February, provided Moderna's shot wins the regulator's blessing. The shots require two doses several weeks apart, to confer maximum protection shown in clinical trials to be around 95 per cent. — Reuters
