Can I still be a primary school teacher?

I'm 15 and in year 11, so I'm looking at what A-levels to do , and I'm thinking that after sixth form, I might like to be a primary school teacher. However, when thinking about it, I'm not very good when people throw up, I tend to get a bit nervous, and I may gip myself. Please be honest, would this mean I couldn't be a primary school teacher?

Thank you 😊👍🏼
