France, Germany and Italy, among other countries, now advise only one dose of vaccine for people with a healthy immune system and a confirmed previous diagnosis.
Be careful quoting what's going on in Germany, there is a lot of false information. Germany is moving to pretty strict rules for non vaccinated, including that to attend things you must have done a test proving you are covid free withing the previous 48 hours AT your own expense, no more free testing. The single jab is becoming a MINIMUM requirement for those that have recovered from Covid, to boost antigens. And you can only use covid recovery as a pass if its within 6 months of recovery date, then you need MINIMUM 1 shot covid booster shots. So it is quite obvious that they consider having had covid as less of protection than teh vaccinations themselves which last 8 months to 1 year before booster is required. Basically in Germany it is set to get very expensive for you to attend any indoor event unvaccinated.
Do not regard minimum requirements by law as what is better for you. These minimums are what they consider the absolute basic requirements for public safety, you can actually get more and not suffer much side effect, but that would be wasting doses as the benefit of more does not significantly boost its effectiveness. Germany was actually pushing to mix up dosing with one AZ and one Pf for maximum effectiveness.
