Herd immunity is not the goal of current vaccines because 1) all levels infections not preventable 2) would need high efficacy for all level of infection & high pop coverage. Please get any vaccine to give better chance of protection from symptoms, possibly severe COVID & death.

Can a person be checked after vax to see if they have antibodies and at what level or of what degree? Should this happen?

Not routinely done. Following a cohort of vaccinated people would certainly improve our knowledge about immunity.

If we were to get the AZ vaccine now, can you get the Pfizer one later?

No research, yet, to rule out switching vaccines the next season.

I understand research has still not determined effects of getting one type of vaccine now and getting a different, possibly more effective one later.

Seasonal vaccination is likely & no research, yet, to rule out having a different vaccine the following season.

Can a person get both the AstraZeneca vaccine and the Pfizer vaccine.?

I told you in a previous tweet the Liberal party will turn this into a cluster fuck.
