I got the initial series of Pfizer's vaccine back in 2021 and continued with it through 2024. Side effects were pretty short-lived but I disliked the elevated heart rate I typically get, so last year I opted for NovaVax. Sides seemed to linger for much, much longer (a week or two) than Pfizer, so this fall I'm thinking I'll go back to mRNA.

My question: Have I "interrupted" the mRNA compound effect by using NovaVax last year? Will switching back to Pfizer offer comparable protection as in prior years? TIA.

Friend has a backyard with extensive overgrowth of what I think is English Ivy. It's more or less contained to 1-2 areas of a large yard and it's fine save for where it grows over a concrete walking path. I tried a wimpy Ryobi weed whacker and it didn't make a dent. Don't really want to crawl on my knees and do it by hand with a pruner.

So: Is there a good (preferably cordless) trimmer that would slice through this stuff along the concrete edge of the path? Would an edger be better? I wouldn't mind renting something, but Home Depot only has a Mikita that looks like a circular saw on a stick. Attaching photo for reference on how I'd like for it to look. Currently, the stuff is taking over the concrete.
