BERLIN, Feb 23 (Reuters) - The World Health Organization has signed a contract with Deutsche Telekom (DTEGn.DE) subsidiary T-Systems to build a software solution for global electronic verification of coronavirus vaccination certificates, the telecoms company said.

The QR code-based software solution will be used for other vaccinations as well, such as polio or yellow fever, T-Systems said in a statement on Wednesday, adding that the WHO would support its 194 member states in building national and regional verification technology.

The financial details of the transaction were not disclosed.

"Health is a strategic growth area for T-Systems," said T-Systems Chief Executive Officer Adel Al-Saleh.
