The director of the World Health Organization (WHO) warned Wednesday that “blanket” vaccine booster shot programs could “prolong” the pandemic, as the United States urged citizens to get their third shots and Israel introduced a fourth dose.
WHO Director-General Tedros Adhanom Ghebreyesus said booster shot programs could extend the pandemic by “diverting supply to countries that already have high levels of vaccination coverage,” allowing the coronavirus to spread and possibly mutate in countries where few citizens are vaccinated, according to CNBC.
