BERLIN — As concerns grow over the highly contagious Delta variant of the coronavirus, Germany on Monday became the biggest Western country yet to announce that it will offer vaccine booster shots to a wide range of people considered potentially vulnerable, adding to growing momentum in rich nations to give additional shots to fully vaccinated people.
The move by Germany came even as a top European Union official criticized the bloc as falling far short of its promises to donate vaccine doses to Africa and Latin America. And with a limited global vaccine supply, health experts say the top priorities should be distributing doses to poor countries that lag far behind in inoculations, and persuading vaccine-resistant people in wealthy countries to get their first shots.
There is also still no consensus among scientists on the need for booster shots, but as fears rise of more pandemic waves and more costly lockdowns, a growing number of countries are preparing to give their people booster doses — or have already started.
Starting in September, Germany, Europe’s largest economy, wants to administer a booster of the Pfizer-BioNTech or Moderna vaccine to older people, residents of care homes, and people with compromised immune systems — and also to anyone who was already fully vaccinated with the two-dose AstraZeneca or single-dose Johnson & Johnson shots, which clinical trials have shown are not as highly protective.
an early leader in vaccination, began administering boosters to people 60 and older last week. A month ago, Russia made additional shots available to anyone six months after inoculation, and on Sunday, Hungary began offering them four months post-vaccination.
France is offering them only to those with weak immune systems, and plans to give them this fall to those who were the first to be vaccinated early this year — mostly people over 75 and those with serious health problems.
government advisers recommended in late June that everyone over 50 should be eligible but said the priority should be getting the shots to people over 70, health workers, nursing home residents, and younger adults with immune problems or other serious vulnerabilities.
