Sadly!! 2 years is nothing. Whilst the UK, Israel, United States and Europe (gradually) are all showing good progress on vaccinations and getting the disease under control. Starting with Japan at less than 1% vaccinated, then India, Asia in General, Africa and South America are all a very long way from any control and natural hurd immunity looks like being the final path for these regions. Sanjay Gupta (CNN's favourite Doctor) said a while back that hurd immunity would take 4 years. I think that that's likely to be where we stand now with final disease control worldwide coming in at around 2025.
