Ivermectin might prevent Covid Mortality - the verdict is not resounding yet. Great for the general population, but for an aviator to have severe disease/symptoms and get Ivermectin and survive with long term damage to lungs and heart would probably cause a loss of license. Could you risk that?
As for masking, lockdown or not, the following chart paints a grim picture of excess mortality. True there could well have been other reasons for the excess deaths in 2020 - just run the same chart with countries that have strict masking, border closures and stricter measures(NZ, ROK, Taiwan) and do a comparison. You can draw some conclusions. Just a comparison of Sweden and other Nordic countries of similar population but applied other measures lockdowns etc.

First spike could well have been all the care home deaths but the 2nd end of year spike, unless they repeated their mistakes. You can paint a similar picture for Italy as well - first spike the terrible toll from Lombardy but another spike at the end of the year, similar in the USA, Belgium, Netherlands, England and Wales. Czech Republic went for a strict masking policy at the beginning of the pandemic - cases were kept low then the summer brought about relaxed masking , the famous party on the Charles Bridge to celebrate - populist government yielding to unmask and you can see the spike at the end of the year.
Vaccinate not because of a particular brand etc. Just use what is available as there's a shortage. Might not be the best but good enough. AstraZeneca is available as well now in Dubai but there won't be enough.
I would love my colleagues who have "left the business" to return. Possibly the quickest way out of this pandemic and for Aviation to revive is for herd immunity through vaccination. Other means may be the perfect solution but will probably result in prolonging job losses, more lockdowns, half vaccinated, more strains to emerge, extended damage to economies, debts - and indeed future of our kids as well.
