Hi Bagpuss @ Sqad,
Immunocompromised patients represent a tricky cohort of patients when it comes to vaccines.
Self-evidently, because immunocompromised patients are unable to offer a strong immune defence against diseases in general, they are more likely to catch the disease and suffer more and longer - And unfortunately they have a higher mortality rate too, for the same reason.
So it makes sense for immunocompromised patients to take advantage of vaccines where they are available, but also to understand that because they have a compromised immune response, it is possible that they are unable to respond properly to the vaccine - this is where consultation with pharmacists/consultants comes in, to determine whether additional doses are desirable or necessary.
Whether or not your symptoms are a side effect of the vaccines or just down to your exposure to imclement weather is more difficult to say, but a mild "flu-like" response is not uncommon having received a vaccine, although and again for the reasons stated above, such side effects are less common amongst those who are immunocompromised.
Grin and bear it - The health value of at least some immunity to such diseases far outweighs the hopefully short - lived mild side effects you might currently be experiencing :)
If it persists for more than 48-72 hours, it might be worth considering visiting your GP......
