I got my fresh respirator cartridges and non-vented eye cover already, plus two freezers full of protein and a job that can be worked entirely from home if needed.

Luckily, there's already an approved influenza vaccine platform that isn't mRNA and, IIRC, they already have H5N1 vaccines produced and stored as a precaution.

Only downside is it requires growing the virus in eggs and processing the concentrated viral stocks produced in the eggs to make the vaccine product. That takes time, but that time is less than the time Operation Warp Speed took to produce the COVID vaxx up until the point of clinical trials (about 9 months IIRC). mRNA will probably be ready far earlier for those willing to take it.

As an example, the Novartis 2009 H1N1 vaccine was approved on September 15, 2009. The virus was first detected in the US in April 2009 and was declared a pandemic in June 2009.
