CNN: Officials are considering a fourth Covid-19 shot this fall

More countries are introducing or exploring the possibility of fourth doses of coronavirus vaccination for their most vulnerable. Israel was the first nation to offer fourth doses, stating in December that people 60 and older, medical staff, and people with impaired immune systems were eligible if at least four months had passed since their third dose. Recently, the Swedish Public Health Agency said this week that second booster doses are now advised for all those aged 80 and up in the country. The Department of Health and Social Care in the United Kingdom stated Monday that people aged 75 and older, residents of care homes for older adults, and immunocompromised people aged 12 and older will be given an extra booster dosage of coronavirus vaccination in the spring. Now, the US FDA is constantly examining fresh data on the pandemic and variations in the US and other countries in order to evaluate the possible utility and formulation of booster doses according to an email to CNN on Friday, from FDA spokesperson Alison Hunt.
