He added that an optional deal for another 30 million shots from Pfizer-BioNTech has also been made.

"Turkey has started phase 1 trials of virus-like particle vaccine today-one of the most innovative vaccine candidates in the world," the minister said.

Saying that Turkey has made significant progress in developing indigenous COVID-19 vaccines, Koca shared that one candidate, developed by Turkey's Erciyes University, will enter phase 3 trials by the end of April as the last volunteer will get the second dose on April 9.

"Turkey is working on the world’s first intra-nasal COVID-19 vaccine," Koca also said.

"Just a single facility will be able to produce over 250 million doses of the vaccine," Koca said.

"Turkey has administered over 14 million doses of the COVID-19 vaccine," Koca added.
