Indeed. "SpikeVax" is the best product name so far, I think.

"Comirnaty" is just a weird name. Apparently they even got a marketing company to come up with it and they gave this reasoning for it:

“The name is coined from Covid-19 immunity, and then embeds the mRNA in the middle, which is the platform technology, and as a whole the name is meant to evoke the word community,” Scott Piergrossi, Brand Institute president of operations and communications, said.

The Oxford/AZ vaccine isn't really much better, as they have picked "Vaxzevria" as their product name. At least it has " vax" in the name so you at least have a bit of a clue as to what it is. On the other hand, the Serum Institute of India also produces this vaccine, but markets it under the name "Covishield", which is much better.

At J&J they haven't bothered with a catchy name and their vaccine is still called "Janssen COVID-19 Vaccine" after Janssen Vaccines, the Dutch J&J subsidiary that developed the vaccine.

The Gamaleya Institute has called their vaccine "Sputnik V", which is weird given that "sputnik" means "satellite". I get the national pride angle they're trying to go for, but viral vector vaccines are not satellites, last time I checked.

Sinovac has called their vaccine "CoronaVac", which is incredibly to the point, but also very unimaginative.

And this concludes a brief roundup of covid-19 vaccine names. It's clear that most of these aren't exactly success stories when it comes to branding. But then again, does it matter?
