As long as there is no crisis of confidence in the ability to repay that debt, it will not be an issue.
That measure has been meaningless for a long time now since the central banks manipulate it for whatever goal they are currently trying to achieve.
With the amount of uncertainty in the current economic climate if interest rates were set by the market they would be skyhigh as nobody would risk loaning money.

Vaccines in human trials in the US now need to go through a 14 month observation period to understand effectiveness and side effects.
Influenza vaccines, if they are any guide, are only 50-70% effective and need to be renewed annually.
Ask people if they are willing to sacrifice 18 months of their life so that someone with an average age of 79 and existing health complications can live another couple of years and you will start to deal with the problem honestly.
By my calculations for every 1 year of saved life (average age 79) we are paying for it with 10 years of lockdown life (average age 35-40).
