WHO says countries should not order Covid-19 boosters while others still need vaccines

Rich countries should not be ordering booster shots for their vaccinated populations while other countries have yet to receive Covid-19 vaccines, the World Health Organization said on Monday. WHO Director-General Tedros Adhanom Ghebreyesus said deaths were again rising from the Covid pandemic, the Delta variant was becoming dominant, and many countries had yet to receive enough vaccine doses to protect their health workers.
