> Vietnam is an epicenter right now, so my odds of catching COVID would be high. ho chi minh is an "epicenter" according to Vietnamese authorities (who have always taken a much stricter, "zero-covid-adjacent" approach to managing covid). While there is always risk, the case-rate is roughly the same as Germany & France (neither of which are in lockdown) & much lower than other western states like the US & UK. The entire country is in lockdown because this is an all-time high by Vietnamese standards (Vietnam have fared similarly to NZ in terms of case-rates before now), despite case-rate in e.g. Ha Noi being low, further mitigating risk factors. So no I don't think the odds of catching it would be significantly higher than wherever you currently reside, unless your humanitarian work is specifically treating covid patients, in which case of course you should get a booster but the destination country is completely irrelevant. Points about hospital capacity are obviously still relevant, but that's not necessarily going to be impacted by boosters as much as vaccination in general: full vaccination rate in Vietnam is only ~5% due to supply issues that are only exacerbated by over-subscription to boosters in western states.
