Whooping cough vaccine (tick). Flu shot (tick). Now add COVID-19 vaccine to the list. Just as it鈥檚 recommended that pregnant women get up-to-date on other vaccines to protect themselves and their families, COVID-19 vaccines are vital.

Sadly, statistics from the last two years indicate that if you are pregnant and get COVID-19, you are more likely to need intensive care or to die, compared to others the same age and health status who get COVID-19. There鈥檚 also a higher risk of pregnancy complications with COVID-19, such as .

This is where vaccination can help. There are now lots of data showing that the mRNA COVID-19 vaccines, such as Comirnaty (Pfizer) and Spikevax (Moderna), are just as safe and effective at preventing severe COVID-19 and death in those who are pregnant or breastfeeding, as in the general population. In fact, immunity gained through vaccination may also be passed onto your baby, protecting them from COVID-19 as soon as they are born. If you鈥檙e not fully vaccinated, don鈥檛 let being pregnant stop you. The vaccine could save you or your baby.

What happens if you get COVID-19 while pregnant?

If you are pregnant, you are not more likely to catch COVID-19 than anyone else, but you are more likely to need to be in hospital, need to be in an intensive care unit or need invasive ventilation (breathing support) if you have COVID-19. Risks are if you have other conditions such as diabetes, hypertension, or cardiac or chronic respiratory diseases. of the most critically ill COVID-19 patients in the UK were unvaccinated and pregnant. Data from France showed that some women who were not yet vaccinated . It鈥檚 a reminder that waiting to vaccinate until after pregnancy won鈥檛 protect against COVID-19 during one of the most vulnerable times.

There are also risks of COVID-19 to your unborn baby. Around born to a mother who was hospitalised with COVID-19 were premature, and the same proportion needed neonatal intensive care.

These risks can be radically reduced by COVID-19 vaccination. Vaccination helps prevent the spread of COVID-19 in the first place, and it improves the body鈥檚 immunity to fight the virus. , 98 per cent of all pregnant people hospitalised with COVID-19 were unvaccinated. It shows that the vaccines are keeping people protected from COVID-19 when they鈥檙e pregnant. It鈥檚 also important for people who live with or spend time with pregnant people to be fully vaccinated and take COVID-safe measures such as physical distancing, good hand-hygiene and mask-wearing where appropriate to minimise the chances of transmitting COVID-19 to them.

Why has there been caution about vaccinating pregnant women against COVID-19?

The initial clinical trials for the COVID-19 vaccinations available in Australia deliberately did not include people who were pregnant. At the beginning of the vaccine rollout, this raised some caution for many people, including some health care professionals, as there was less available data to make informed choices.

But now that the vaccines have been rolled out across the world, researchers and regulators have been able to compare large numbers of cases and perform good studies, particularly in the Comirnaty and Spikevax vaccines. For example, in the US there is of approximately 180,000 (as of 17 December 2021) pregnant people who received mainly Comirnaty (Pfizer) and Spikevax (Moderna) vaccines, and there were no reported safety concerns. have also shown that the vaccines are equally as safe and effective in pregnant people as in those who are not. Governments and across the world now strongly recommend that against COVID-19 as a priority.

How does immunity transfer to the baby too?

A bonus gift of vaccination is that the baby is likely to have immunity to COVID-19 too, as it does with other routine vaccines. of 36 vaccinated pregnant women showed that antibodies against COVID-19 were found in the baby鈥檚 placental cord blood in every case. This process happens naturally as antibodies are passed from mother to baby through the placenta and it is known as . This is especially important because babies aren鈥檛 yet eligible for COVID-19 vaccination, so they will have some protection against COVID-19 as soon they are born.

There鈥檚 a lot of conflicting information in the community, especially on the topics of maternal health, vaccines and COVID-19. Always check the source of the information is from a credible organisation, and if possible, look at how recently it was published. Some good resources for extra information on COVID-19 vaccination during pregnancy include this from the Australian Government Department of Health and this from The Royal Australian and New Zealand College of Obstetricians and Gynaecologists. For Australians who don鈥檛 speak English, the Migrant Council鈥檚 app, , has a wealth of COVID-19 information available in multiple languages. If appropriate, share these resources with the expecting parents in your life. Together, we can push through the misinformation to reduce the harm from COVID-19 for ourselves, our families and our communities. And remember: don鈥檛 wait to vaccinate.
