According to the chairwoman of the UK Vaccine Taskforce, a COVID-19 vaccine could be given to some of the most vulnerable people "this side of Christmas," reported BBC News.
However, Kate Bingham suggested limited supplies would mean the UK government would have to decide who should get it, and when.
Bingham said she was optimistic that a vaccine would be found that would "protect some people from infection and can reduce the severity of symptoms," but that it was "very unlikely" to be a single dose and that ongoing revaccination would be needed probably every few years.
The Joint Committee on Vaccination and Immunisation (JCVI) has already advised that vaccine distribution should be prioritised by need, with care home staff and the elderly population first in the queue.
One worry, Bingham said, is that work on a vaccine would have to start again from scratch if the virus was to mutate sufficiently in the future.
However, she was hopeful that by 2022 there would be no need for people to wear face masks, and was more confident that we could be bringing in 2022 with family gatherings and parties.
