Almost 30 years living with PSO and the latest drug I am on is Tremfya
I spoke to my specialist yesterday as I'm on biologics and asked them about the vaccinations. In my case, as I'm on a drug that currently suppresses my immune system, he recommended that I ask my GP to prescribe only the 2 American developed vaccines but to avoid the Oxford developed one.
The American vaccines are protein-based which program the immune system to generate the antibodies where the Oxford one is a 'live' vaccine so seeks to 'infect' you so that your immune system develops it naturally. At least that's how he explained it to me...
Now this is info based on my current medication that reduces the immune system. It might be different depending on what medication you're currently taking so it would be worth speaking to your GP and/or skin specialist to make sure what I've just regurgitated is correct...!
