Novavax is not an mRNA vaccine and it has been approved as a
first booster. The company "believes" it provides durable protection against variants, but I have not seen proof of this.
Personally, I'm planning to get a bivalent booster. For me, it's just a timing issue.
>>>Novavax’s newly authorized booster was developed against the original strain of Covid but the company believes its protein technology provides durable protection across different variants of the virus. Novavax’s shots rely on more conventional technology used in other vaccines for decades rather than the newer messenger RNA platform used by Pfizer and Moderna.
Novavax said its booster doses triggered robust antibodies against omicron BA.1, BA.2 and the dominant BA.5 subvariant
in studies that observed adults who received the third shot 8 to 11 months after receiving their Novavax primary series.
The booster dose also induced an immune response in participants who received Moderna, Pfizer and Johnson & Johnson as their primary series, according to the company.<<<

This article says it "may be" effective against omicron:
>>>Oct 12 (Reuters) - Novavax Inc
(NVAX.O) said on Wednesday data from studies in adults and adolescents showed that the booster dose of its COVID vaccine produced robust antibodies against several Omicron variants, including BA.1, BA.2 and BA.5. . . .
In the late-stage study, a single homologous booster dose significantly increased antibody levels against these variants relative to pre-boost levels, the company said.
"These data are an early indication that our vaccine may be effective against variants such as Omicron," Novavax executive Gregory M. Glenn said.<<<

I have to believe Novavax is better than nothing (I realize you are not in the "nothing" category, of course, that's just a general observation/opinion).
