Montreal Interview - Vaccines

I am missing a couple of vaccines that are required prior to my interview - the 10 year tetanus renewal and a flu shot.

I am visiting the USA anyway between now and my interview in Dec so I am wondering if it would be fine to get those two vaccines in the US?

The reason I am considering this is because I don’t have a family doctor in Canada and the pharmacies won’t give out tetanus shots. CVS provides most of the immigration vaccines and it’s easy to schedule so from a convenience standpoint, it would be easier to slot into my schedule.

Curious if anyone has gotten their supplementary vaccines in the USA and if it’s raised any flags at the interview. Thank you!
