WHO recommends booster dose against Coronavirus

World Health Organization has recommended the COVID-19 booster shots, reversing its position. In a statement, WHO said its expert group concluded that immunization with authorized COVID-19 vaccines provide high levels of protection against severe disease and death amid the continuing spread of the hugely contagious omicron variant. It said vaccination, including the use of boosters, is especially important for people at risk of severe disease.

The WHO said that to ensure COVID-19 vaccines provide



optimal protection in the future, they may need to be updated as new, antigenically distinct variants emerge.

The WHO further said it continues to monitor the global spread of Omicron, including a 'stealth' version known as BA.2, which has been documented to have re-infected some people after an initial case of omicron.

WHO eased back on its earlier position in January by saying boosters were recommended once countries had adequate supplies.
