Is vitamin D stopping me from catching everything like usual?

[Butterflypattern]

I’ve been taking vitamin D3 everyday since last March.
I’m usually catch everything going as I work in a school and I have a toddler who goes to nursery. He’s just got over a very nasty virus (not Covid) but he had a high temp, cough etc and was ill on and off for over a week. Usually I would catch something like this, but I didn’t.
I haven’t actually been properly ill since around September of last year when I had a generic virus that was mostly sore throat, fever and snotty.

I also haven’t had either vaccine because I’ve got a severe phobia of needles.

So I guess I’m just wondering is vitamin D3 helping my body warn off infections and viruses?

If you actually get severe Covid you will likely need way more than 2 needles in your arm to receive treatment.

Get the vaccine. Talk to your GP about any ways to help you manage the phobia (emla cream to numb the area etc?).

Vitamin D3 will not keep you safe from Covid

I’ve been taking vit D for years as I tend to be low regardless of my sun exposure and diet.

I’ve not had any illness at all since the start of covid. The only thing that has changed in that time is social distancing, masks and improved hand hygiene.

Vit D will do you good but it’s not going to stop you catching and suffering respiratory illnesses.

Vitamin D is generally a good thing for immune system and bone density. It is difficult in the UK to maintain good levels of vitamin D all year round (and with all the overcast weather this "summer" it's not a been good one for vitamin D)

Covid is a lot of the luck of the draw. Vaccination boosts resistance and immune response, but but the number of contacts, proximity and ventilation are also influential. (I love the way that the hands, face, space bit ignores the key bit about maximising fresh air flow/ outdoor contacts ) The handwashing is beneficial for some illnesses more than others, norovirus being significantly reduced by reduced touch contact.

I had a succession of minor sniffles last September when the DCs went back to school for the first time in 6 months of minimal indoor contact with people. Then we've not had issues since, mainly because our interactions are still not normalised. Groups like Scouting were still outside through the summer term, the weather's been tolerable enough to meet socially outside or open windows. People are more cautious about meeting with any kind of minor symptom that we'd normally overlook because it's not worth the bother of a testing scare.
Saying that, in general it's good to keep our immune systems up to date with the usual range of minor illnesses and New Zealand is currently struggling with clusters of RSV affecting children because of the disruption to usual seasonal trends and exposure.

Vitamin D is good but there are a lot of variables at play!
