Modern vaccine component crossword clue
59 Down · WSJ Crossword, August 18, 2026 · 3 letters
Explanation
The answer to “Modern vaccine component” is RNA. It appears as 59 Down in the Wall Street Journal crossword of August 18, 2026, a Tuesday puzzle titled “On The Corner” by Kelly Richardson, and it fills 3 squares running top to bottom from row 13, column 11 of the 15×15 grid.
The clue is a straightforward definition, so the answer is a direct synonym or a factual match for the words as written. The entry begins with R and ends with A, and contains 1 vowel and 2 consonants. If you are working from the crossings, two or three confirmed letters from the Across entries should be enough to lock it in. Tuesday puzzles stay approachable with light wordplay, so expect the rest of this grid to be pitched at the same level.
