I decided to get them at different times because I often have a pretty strong response both in terms of arm pain and general ick. I got my COVID first and plan to get my flu shot second. I’m really glad to have a reference to this post for those who are weighing the choice!

Getting one shot in each arm was an interesting experiment for me. I first did it last year, and then again last week. From getting them separately, I was sure they would both cause arm pain, but the Moderna COVID shot would be worse.

Last year, I was surprised that the flu arm felt worse. But then a few hours later the arm pain from the COVID vaccine really kicked in, and stuck around for a few days as it had with past doses. So my expectation wasn't wrong; it just took the COVID vaccine longer to start causing the pain. This year was a pretty much identical experience.

I wonder if this means it is the actual spike protein that causes the pain, and so it doesn't kick in until my cells synthesize it?

Hey, you got it over with! Without leaving well referenced commentary here, I recall one study showing that about 10% of people had more severe side effects when getting both flu and Covid shots together. In terms of efficacy, I don’t think there’s a problem.

I got my flu shot today and I’m gambling I won’t get Covid before I get my mRNA booster as scheduled in mid October. Also hard to find the mRNA boosters freely in pharmacies right now and I’m not super high risk so I don’t want to take anyone else’s right now (48 yo).

And I don’t have a whole lot of faith that Novavax will get over the finish line, they have stumbled many times previously.

Salud 😊
