The UK has approved the Pfizer coronavirus vaccine with the first recipients set to receive it as soon as next week.
Ahead of the roll-out, the government has published two documents outlining further details of the vaccine including how it works, what it contains and what the possible side effects may be.
The information, which can be found on the government website here, also contains specific advice for women who are pregnant, breastfeeding or planning on getting pregnant.
According to the guidance, there is limited data on what the effects of the vaccine may be in pregnant women.
Healthcare professionals are being advised that the vaccine is not recommended during pregnancy, and possible pregnancy should be ruled in any women who are getting the vaccine.
The vaccine is also not recommended in anyone who is breastfeeding, as it is still unknown whether the vaccine may be excreted in human milk.
Anyone who is either pregnant, thinks they might be pregnant, is breastfeeding or is planning on getting pregnant, is urged to contact their doctor before receiving the vaccine.
If you get the vaccine, you should avoid getting pregnant for at least two months afterwards.
Research has shown that pregnant women are no more likely to become ill with severe coronavirus than non-pregnant woman.
The vaccine has been shown in studies to be 95 per cent effective.
The Joint Committee on Vaccination and Immunisation (JCVI) has said the elderly are most at risk from coronavirus and should get the vaccine first, followed by those aged 80 and above and frontline health workers.
The UK has ordered 40 million doses of the Pfizer vaccine, enough to vaccinate 20 million people with two doses, given 21 days apart.
