I'm still weighing up the options: am already double vaxxed without issue but now the consideration is whether to risk any possible complications of number 3 with the possible benign reaction to getting Omicron, which I want anyway for the long term immunity. Apparently those with double vaxs are only very marginally less "immune", whatever that means, to the virus than those with 3, and from what I've read/heard the effects of the virus (Omi) are negligible - WHEN YOU'RE VAXXED.
Not taking a third shot may not be an issue for you IF you remain in Bali, but it MAY impact you if you choose to travel, e.g., I can see Australia probably requiring a booster for you to be considered to be 'fully' vaxed, not too far in the future.
