I got my first Novavax shot as a 4th dose on 11/11 at Safeway with a high dose flu shot. was told efficacy should kick in, in about 14 days. The only exposure I could have had was a large all day Christmas event 15 days later, which was last saturday. I started having hoarseness and flu type symptoms on tuesday and tested positive for covid yesterday. (I did not test before that because I thought there was no way I got covid after getting the Nvax shot) This morning, I am definitely feeling better than the last few days.

I think someone else posted that they got covid within 2 weeks of the Nvax shot  but could not find that post.
