Coronavirus does actually mostly fit with Japanese pronunciations of singular letter consonant-vowel pairings, with a dropped vowel on words ending with "s(u)". Ko-Ro-Na-Vi-Ru-Su and Ko-Ro-Na-Va-I-Ru-Su both fit japanese phonetics.

It's not like you're trying to say "Strength" or something which simply does not map to Japanese at all.

They do not drop the vowel after "r" sounds. In fact, they're not much fans of "r" sounds in general, but exceptions exist there. But they don't drop the vowel. Find one word that does, that ORIGINATES in Japan. Even words outside Japan, they bastardize significantly in order to render them pronouncible.

Ko-Mi-Lu-Na-Ti =/= Comirnaty. It can be safely said the word origin is not Japanese in nature. Even trying to ape English sounds, they wouldn't pick a shortened R/L.
