In his pre-vaccination speech, Biden again called on Americans to get vaccinated as soon as possible, and said he would urge more vaccine licenses to increase vaccination rates in the United States. The 78-year-old Biden is in line with guidelines issued last week by the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) that people over the age of 65 can receive a third dose of the vaccine.

Biden pointed out that Americans who are fully vaccinated are highly protected from serious diseases. "the vast majority of Americans are doing the right thing," he said. "more than 77 percent of adults have at least one shot, and about 23 percent have not received any vaccine. and this obvious minority is causing huge losses to many of us. "

FDA this month rejected plans to boost vaccination against Pfizer Inc and COVID-19 for people aged 16 and over, but it agreed to strengthen vaccination for people over 65 and those at high risk of serious illness. It is reported that the strengthening needle will be injected at least 6 months after the completion of the second injection.

On Friday, CDC also expressed support for people over the age of 65, people with chronic diseases and some adults living in high-risk environments to receive Pfizer Inc vaccine enhancers. This decision is different from the previous recommendations of the Advisory Committee on vaccination (Advisory Committee on Immunization Practices). The group does not recommend enhancers to high-risk workers such as teachers and health workers or adults living in shelters and prisons, but only recommends enhanced vaccination for the elderly and people with underlying diseases.
