On Friday 11 December, the European Medicines Agency (EMA) hosted an online stakeholder meeting on COVID-19: how safe and effective vaccines are developed and authorised in the EU?
At the meeting representatives from the EMA discussed how COVID-19 vaccines are developed, how they are evaluated and how safety is monitored.
During the second half patients/carers, consumers/citizens, industry, healthcare professionals and academics could present and ask questions to the EMA.
Here we have summarised some key points that answer some questions we at ELF have received about COVID-19 vaccine development.

EMA also have a COVID-19 vaccine key facts page which is a useful resource: https://www.ema.europa.eu/en/human-regulatory/overview/public-health-threats/coronavirus-disease-covid-19/treatments-vaccines/covid-19-vaccines-key-facts
There has been an effort to include people with underlying conditions in the studies. Although the numbers are not yet known, there should be at least 1 in 10 people in the trials that have an underlying condition. Once the data are released, the EMA will be open about the number of people in the studies who had underlying conditions.
In each trial there should be around 1 in 4 people who are over 65. Women and people from marginalised groups should also be well represented. EMA will consider these factors in its decision when assessing the safety and efficacy of the vaccines. EMA will also ensure that this information is transparent and accessible.
As pregnancy is often part of the exclusion criteria for medical trials, more data are needed to understand the safety implications for pregnant people.
Participants in the trials will be followed up for a minimum of 6 weeks. Most side-effects happen within 4-6 weeks of having a vaccine. The trials will last up to a year to better understand the level of longer-term protection and side-effects.
Once the vaccines are released, there will be a robust monitoring plan for managing the safety of the vaccine. All new data about the vaccines will be monitored and assessed on a rolling basis. If there are concerns, then the conditions for the vaccine being available can be re-assessed. If the conditions are not met, then the vaccine can be withdrawn.
