Vaccination at a massive scale is crucial to quickly manage the spread of the virus and
relieve symptoms of infection. According to the Green
Book of COVID-19, currently, candidate SARS-CoV-2 vaccines such as Pfizer-BioNTech COVID-19
vaccine
and AstraZeneca COVID-19 vaccine have shown about 95% clinical efficacy in phase 3 safety trials.
Immunisation Programme
As the COVID-19 pandemic sweeping the world, Britain began to implement nationwide
vaccination to achieve herd immunity. The COVID-19 immunisation programme in the UK is the world's
first mass immunisation campaign to protect against SARS-CoV-2 using vaccines developed in response
to the COVID-19 pandemic. In London, hundreds of clinic places such as pharmacies, hospital hubs and
Primary Care Networks (PCNs) have been transferred to vaccination sites to cover the demand of
vaccine services.
Vaccination Priority
Since the elderly and people with underlying health conditions are more like to suffer and die from the infection,
according to the
priority group
set by the government, people who are at high risk of severe
illness, such as the elderly will be given priority to be vaccinated.
