A HEALTH chief has warned that Cumbria needs to keep coronavirus cases low to avoid more variations emerging as the vaccination process rolls on. Pfizer and AstraZeneca vaccines have been shown to cut transmission in anyone who catches Covid-19, 24 hours after receiving even their first dose. Cumbria has recorded levels of Covid-19 not seen since August and about three quarters of the eligible population have had their first dose. Meanwhile, health bosses across the globe are expressing concern at the situation in India. Cumbria’s director of Public Health Colin Cox said: “The situation in India is absolutely awful at the minute and it may feel far flung, but there’s an awful lot of people in this country with family there who may go and come back.
