The impact of a new Covid vaccine will kick in significantly over summer and life should be back to normal by next winter, one of its creators has said.
Prof Ugur Sahin, co-founder of BioNTech, said this winter would still be hard as the vaccine would not have a big impact on infection numbers.
Last week, BioNTech and co-developers Pfizer said preliminary analysis showed their vaccine could prevent more than 90% of people from getting Covid-19.
About 43,000 people took part in tests.
The UK is expected to get 10 million doses by the end of the year, with a further 30 million doses already ordered. The vaccine is given in two doses, three weeks apart.
Older residents and staff in care homes are likely to be prioritised, followed by health workers and the over-80s. People would then be ranked by age.
In an interview on BBC’s Andrew Marr Show, Prof Sahin said he was confident the vaccine would reduce transmission between people as well as stop symptoms developing in someone who has had the vaccine.

And? What about if there is another virus by then?
Annual or frequent vaccination may be required, I think.
What about the developing countries….? And how much will it cost them?
