Pregnancy, teaching, covid

[M2B91]

Hi all,
First of all I just want to applause all the pregnant women out there that are doing so well and have made me think this was going to be easy.
I for one am massively struggling- exhaustion, nausea, some days contact sickness, aches, pains, headaches, bowel problems, you name it, I’ve got all the symptoms! I’m 12 weeks pregnant and my hormones are all over the place. I work as a primary school teacher with a really difficult year 1 class who are massively behind due to covid. Not only are they behind academically but they are not independent one bit and need constant refocusing which is exhausting! I’ve ended up having days off here and there because it’s just getting way too much for me and I feel really bad!
Now we have many children in class who have tested positive for covid and numerous family members of children who have covid but are still sending there children in (I get this is the new guidelines but it’s scary!).
Anyway we didn’t take covid into account when doing my risk assessment and I have not had my booster due to feeling so unwell after my first and second jab.
Our office lady has just given birth and was not allowed any contact with children the whole way through her pregnancy - our head told all staff to under no circumstance send any child to the office so that we could safeguard said pregnant lady.
However I’m now concerned that I am not being safeguarded and am putting myself at risk on top of feeling like crap everyday anyway!
I know every pregnant women is having to work in difficult situations at the moment and I completely empathise with you and and just wondered if you had any advice for me?
In an ideal world I’d work from home until cases drop but my head isn’t going to suggest this for inclusion reasons.
Sorry for the long message and thank you to anyone who responds

@M2B91 While these vaccines are still fairly new, the science behind them is well-understood, as are the components.

The vaccines used in pregnancy never leave the muscle tissue in your arm - they're broken down there - so there's no way it could cross the placenta. They aren't live vaccines, so they don't actually contain any active virus. What they do is basically show your immune system a 'blueprint' for a piece of the virus which is quite recognisable (the 'spike protein'), so that your immune system knows how to defend against it - kind of like how in 'Star Wars' the Rebel Alliance were able to develop a plan to defend against the Death Star because they saw the blueprints in advance of the final battle. (spoilers for Star Wars Episode 4, I guess).

I work in healthcare and have been patient-facing throughout my (high risk) pregnancy, up until I started mat leave (at around 35 weeks). I've seen the effects of COVID in pregnancy and the vaccines can make a huge difference. My honest opinion is that the science behind them is sound, and that the very small risk of an 'unknown unknown' risk emerging regarding the vaccines is much safer than the very well known risks of COVID in pregnancy.

@M2B91 I was being seen by a consultant anyway so just mentioned it at my appointment, to say they were horrified I was working with 5 year olds with no distancing would be an understatement and I was told not to go back at all so called from my appointment, got stuff from school when it was empty then worked from home
