GENEVA (Reuters) -The World Health Organization (WHO) recommended on Thursday that people who are immunocompromised or received an inactivated COVID-19 vaccine should receive a booster dose to protect against waning immunity.
Many countries have been rolling out booster shots, targeting the elderly and people with underlying health issues, but worries about the new, more transmissible Omicron variant have prompted some to expand their use to larger portions of their populations.
