Harrow Council has urged people to sign up for trials that could help provide a vaccine against Covid-19.

In its latest newsletter, it explained that “more volunteers are needed” to boost the chances of finding a “safe and effective jab” quickly.

This is particularly relevant for Harrow, since it a high proportion of groups disproportionately affected by the virus – those from black, Asian, or minority ethnic groups and those aged 65 or over – who are considered priority triallists.

According to the NHS, “vaccines are the most effective way to prevent infectious diseases” and “research into vaccines is the only way to find out which ones will work”.

Currently, two vaccine studies have been approved by the NHS’ research partner, the National Institute for Health Research – one run by the University of Oxford and another by Imperial College London.

Those who decide to take part in the trials will need to visit hospitals or research sites several times over six to 12 months where they will usually be given an update on the research and have blood tests.

The NHS explained participants will need to monitor any symptoms and may be required to carry out throat and nose swabs, or keep a diary.

More than 200,000 people have volunteered so far, visit www.nhs.uk/sign-up-to-be-contacted-for-research for more information.
