Pfizer Nears Submitting Data to FDA for 4th COVID-19 Shot

Other countries such as Chile, Israel, and Sweden already allow for a fourth dose if the patient is in a vulnerable position. However, with omicron-related cases significantly decreased, the FDA has to determine if a fourth dose is necessary. Federal officials have said they are continuing to evaluate if and when a new spike in cases will occur. A Harvard epidemiologist agrees with the vaccine makers that additional doses may be necessary for certain groups such as the elderly and those with underlying health conditions.
