Short study name (acronym)

Vaccination in pregnancy - ideas, experiences and attitudes, London (VIP-IDEAL)

Who conducted this study?

The study was conducted by a research team from the London School of Hygiene and Tropical Medicine at the University of London.

Where and when was the study conducted?

The study was conducted in South London in 2022.

Why was the study done?

The researchers wanted to find out which vaccines women were offered during pregnancy and what they thought about them. They looked at vaccines against whooping cough, flu and Covid-19.

In some areas, only few people took these vaccines during pregnancy, and the researchers wanted to find out why. They also wanted to find out how things can be improved in the future.

The researchers wanted to hear from people from different social and ethnic backgrounds. This was to ensure that the experiences and worries of different types of people living in South London are understood and considered in the future, including from those who did not get vaccines during pregnancy.

Who took part in this study?

Both healthcare service users and providers took part:

1. A total of 38 pregnant or recently pregnant women
2. A total of 20 service providers, including 12 midwives, 2 family doctors, 3 pharmacists and 3 other providers

What happened during the study?

The researchers conducted interviews with 31 healthcare service users and 20 providers and a group discussion with seven service users. Participants could choose whether to be interviewed over the phone, via video conferencing, or in person. The interviews lasted about 20 to 90 minutes.

With consent of participants, the interviews and group discussion were audio-recorded and analysed.

What were the overall results of the study?

The pregnant or recently pregnant women in the study said they took either all, none, or some of the vaccines. The most common vaccine they took was for whooping cough, followed by flu and only few took the Covid-19 vaccine. Some women were unsure if they were offered the vaccines, while a few others forgot them or could not get them. A few were advised against the Covid-19 vaccine by their midwives.

Many people in the study, including midwives, said that it was up to the pregnant women to do their ‘own research’ about the vaccines and then decide if they wanted them. But many women felt they did not get enough information from midwives about where and when to get the vaccines and how safe and important they are. So they looked for information elsewhere, including online and on social media with the risk of getting wrong information. This made them more worried about vaccine side effects, especially for Covid-19.

Not just the pregnant women, but also some of the healthcare workers were confused when the government changed its advice in April 2021 and said pregnant women should get the Covid-19 vaccines. Some participants found that healthcare workers themselves did not have enough information about the vaccines and needed more training. Many participants found that we need more research to find out if new vaccines have any long-term effects on pregnant women or their babies. Many healthcare workers said that they did not have enough time to discuss vaccines with pregnant women.

Some also said that the computer systems were not good for reminding people about vaccines and keeping track of who got them or what was discussed. Most pregnant women were told about a pregnancy app, but were not told how to use it and did not know it had information about vaccines. Some pregnant women preferred to have information on paper instead of using apps. Some participants also spoke about language problems.

Overall, many participants talked about how the healthcare was organised and how that affected the decisions pregnant women made about vaccines and how to get them. Some participants also discussed where vaccines should be offered, and a few suggested that more vaccines should be offered in pharmacies. Many participants had ideas on how to make things better, for example, giving pregnant women more personalised information in different languages.

How has this study helped patients and researchers?

During the quite long interviews participants from different ethnic backgrounds were able to share their experiences and thoughts on vaccinations in pregnancy during the Covid-19 pandemic. Not everyone thinks the same, and the people who took part in the study might be different from others. We noticed, for example, that the midwives who took part were more pro vaccine than some of the midwives mentioned by the pregnant women. Nevertheless, it was very helpful to hear from both sides, including service providers and clients.

The information from this study can help researchers to improve health programmes with the help of healthcare providers and the public. It might also influence decisions about new vaccines that might become available in the future.

Who funded and approved this study?

The VIP-IDEAL study was funded by the Wellcome Trust (a charitable foundation with focus on health research) through an LSHTM Institutional Strategic Support Fund (ISSF) Pump Priming Grant (Wellcome ISSF Pump Priming Grant reference: 204928/Z/16/Z). Two of the authors (Sandra Mounier-Jack and Oyinkansola Ojo-aromokudu) were supported by the NIHR Health Protection Research Unit in Vaccines and Immunisation at  LSHTM in partnership with the UK Health Security Agency (UKHSA).

We obtained approval for the study from the NHS Health Research Authority, the London - South East NHS Research Ethics Committee and the LSHTM Research Ethics Committee.”
